Renin Angiotensin Aldosterone System
 
03:43
This animation focuses on the renin angiotensin aldosterone system (RAAS), a classic endocrine system that helps to regulate long-term blood pressure and extracellular volume in the body. Many aspects of cardiovascular disease progression can be directly linked to the RAAS system. Mechanisms such as vascular inflammation, generation of reactive oxygen species and alterations of endothelial function are all known to play a role in atherosclerosis.

If in the US use this link http://goo.gl/mDMfj5 If in the UK use this link http://goo.gl/j0htQ5 One of the proteins present in the blood is called angiotensinogen. This is a short protein produced by the liver and is inactive; it just circulates in the blood. However, when renin acts on angiotensinogen it converts it into another shorter protein called angiotensin I. As angiotensin I passes through the lungs it is converted into angiotensin II by an enzyme called angiotensin converting enzyme (ACE). Angiotensin II is a powerful vascular vasoconstrictor; this will increase peripheral resistance which will in turn increase blood pressure. In addition to increasing BP by direct vasoconstriction angiotensin II also stimulates the secretion of aldosterone from the adrenal cortex. This will increasethe amount of sodium reabsorbed from the renal tubules and so increase levels of sodium in the blood. As mentioned, increased levels of sodium increases the osmotic potential of the blood and so it attracts more water. This means more water is retained in the plasma increasing blood volumes. These increased volumes will increase venous return and so blood pressure. Conversely, lower amounts of angiotensin II will reduce aldosterone secretion leading to more sodium excretion. This will lower sodium levels in the blood leading to lowered blood volumes and so lower BP. If the systemic blood pressure is increased the pressure in the afferent arteriole will also be increased. This will be detected by the JGA cells which will respond by reducing renin secretion. When less renin is present in the blood, more angeotensionogen will remain in inactive form. This renin-angiotensin-aldosterone mechanism allows the kidneys to regulate their own blood flow to an extent. When an organ regulates itself in this way it is called autoregulation. If for any reason the kidneys over-secrete renin blood pressure will be raised. An abnormally high BP is termed hypertension. Renin excess probably explains most cases of chronic hypertension. You may have come across ACE inhibiting drugs; these inhibit ACE (angiotensin converting enzyme) and so inhibit the conversion of angiotensin I into angiotensin II. If there is less angiotensin II there will be less vasoconstriction and less secretion of aldosterone and so blood pressure will be lowered.

Quick Pharmacology: Hypertension (Cause & Blood Pressure regulation) Part 1 of 2
 
05:04
I recommend the Rang and Dales Pharmacology book for an in depth understanding of various pharmacological topics: https://amzn.to/2sR0XPC Arterial blood pressure is what drives blood to tissues and organ and is adjusted depending on oxygen requirements how blood pressure is regulated. It is regulated by the sympathetic nervous system. The SNS releases the NT norepinephrine aka noradrenaline which acts on several receptors: It Acts on 1 receptors in the heart It Acts on 1 receptors in arteries and arterioles causing constriction Lastly it Acts on 1 receptors in vein and venules causing constriction The cardiovascular centre in the medulla oblongata is the central control of blood pressure It receives Input from: Baroreceptors which are in the aortic arch and carotid arteries. The cardiovascular centre then reviews the inputs and decides whether to increase or decrease the blood pressure through the following Outputs: 1. The Vagus nerve which is Para sympathetic so decreases HR 2. The Cardiac accelerator nerve which is Sympathetic so increases HR and contractility 3. And the Vasomotor nerves which are Sympathetic and cause vasoconstriction Now let’s cover the humoral control of blood pressure. The first is the renin angiotensin aldosterone system or RAAS for short. The second humoral control of blood pressure is via the anti-diuretic hormone vasopressin which is synthesised in the hypothalamus and secreted from the posterior pituitary gland. The last humoral control of blood pressure is via natriuretic peptides. There are two main antipsychotic drugs used against schizophrenia. The first are typical antipsychotics. Examples include phenothiazine’s, butyrophenones and thioxanthines. These drugs block D2 receptors in the mesolimbic pathway and so relieve the positive symptoms of schizophrenia. They have little effect on the negative and cognitive symptoms as there is already a decrease in dopamine in the mesocortical pathway so blocking dopamine receptors in that area doesn’t elicit any useful effects. The first main side effect of using these drugs are extrapyramidal symptoms which are symptoms mainly associated with involuntary muscle movement. This is due to the blockage of the D2 receptor in nigrostriatal pathway and Also due to an increase in ACh release in the substantia nigra. They also cause Hyperprolactinaemia due to an increased secretion of prolactin due to the blockage of D2 receptors in Tuberoinfundibular pathway. Anticholinergic side effects such as dry mouth, constipation, blurred vision, tachycardia and urine retention occur due to the blockage of the MAChR. And lastly hypotension can occur due to the blockage of the H1 receptor. The second type of drug that can be used in schizophrenia are atypical antipsychotics. These drugs are: High affinity D2 and 5-HT2A receptor blockers. They Also block D4, M1, M2, M3, M5AChR, H1 and 1 receptors. And lastly they are full agonists of M4AChR They are effective in 60% of the patients who are unresponsive to typical drugs and in Most cases equally effective in reducing the positive symptoms. Unlike typical drugs, they also reduce the negative and cognitive symptoms because they block the 5-HT2A receptors. However, atypical drugs may have more side effects that typical drugs. These include metabolic side effects: due mainly to blocking 5HT and H1 receptors. This can result in hyperglycaemia which is increased blood glucose levels which can increase the risk of diabetes. Abnormal lipid profile and Weight gain. As a result, caution has to be taken when administering these drugs to patients with a family history of diabetes and CVD. Atypical drugs can also cause anticholinergic effects, hypersalivation, orthostatic hypotension, sedation, agranulocytosis and an increased incidence of seizures. On the other hand, there are less extrapyramidal symptoms seen with these drugs and they usually don’t cause hyperprolactinaemia.

Water Regulation by Antidiuretic Hormone (ADH)
 
06:22
Water Regulation by Antidiuretic Hormone (ADH)/ Antidiuretic Hormone animation/Antidiuretic Hormone mechanism/Antidiuretic Hormone physiology/Antidiuretic Hormone function The hypothalamus produces a polypeptide hormone known as antidiuretic hormone (ADH), which is transported to and released from the posterior pituitary gland. The principal action of ADH is to regulate the amount of water excreted by the kidneys. As ADH (which is also known as vasopressin) causes direct water reabsorption from the kidney tubules, salts and wastes are concentrated in what will eventually be excreted as urine. The hypothalamus controls the mechanisms of ADH secretion, either by regulating blood volume or the concentration of water in the blood. Dehydration or physiological stress can cause an increase of osmolarity above 300 mOsm/L, which in turn, raises ADH secretion and water will be retained, causing an increase in blood pressure. ADH travels in the bloodstream to the kidneys. Once at the kidneys, ADH changes the kidneys to become more permeable to water by temporarily inserting water channels, aquaporins, into the kidney tubules. Water moves out of the kidney tubules through the aquaporins, reducing urine volume. The water is reabsorbed into the capillaries lowering blood osmolarity back toward normal. As blood osmolarity decreases, a negative feedback mechanism reduces osmoreceptor activity in the hypothalamus, and ADH secretion is reduced. ADH release can be reduced by certain substances, including alcohol, which can cause increased urine production and dehydration.

Low Blood Pressure caused by Adrenal Fatigue
 
06:03
https://www.drlam.com/blog/signs-symptoms-low-blood-pressure-causes-correlation-adrenal-fatigue/19097/ This is Dr. Lam, founder of DrLam.com and today we are going to talk about low blood pressure consistently. Now, blood pressure is an automatically regulated mechanism in our body. It is designed to provide oxygen through blood, through our brain, as well as various parts of our body. The regulation of blood pressure falls within many factors. Blood volume can effect the blood pressure, the endothelial wall of the blood vessel itself constricting and dialating through what we call baroreceptors or blood pressure sensitive receptors can help modulate the blood pressure, and of course electrolytes and the sodium balance can also play an important factor. The organs responsible including the kidneys, the adrenals, as well as the brain, can also make a big factor in regulating the blood pressure on a 24/7 basis without us knowing. Of course we can not discount the role that the heart plays as well. So maintaining normal blood pressure is a very important part of survival. Just going from a sitting to a standing position requires that it activates all the systems in various degrees so that we can stand up, not feel dizzy, and are able to walk and not feel dizzy and then have normal activity. Any time the blood pressure is not regular the brain is not getting enough profusion or blood flow, and then the body will suffer. In the case of adrenal fatigue, what happens is, because the adrenal glands regulate the sodium and potassium balance, there is a tendancy, as the adrenals get weaker, that the body is not able to regulate this as much as it should. As a result, the sodium is usually lost through the deficieny or the subclinical effectiveness of aldosterone: the hormone that is regulating the blood flow and the water flow. Now this hormone is critical because in adrenal fatigue this hormone aldosterone tends to be low. As a result the sodium is not going to be easily maintained in the body. At this time the labratory values may be the same, or when I say the same I mean normal. People come in a lot of them with low blood pressure because they are losing sodium, and without sodium your water does not flow. So in other words the water stays with the sodium, wherever the sodium goes the water goes. So as long as the sodium is high the water will be retained in the body. When the sodium is low then the body will tend to lose water, and if you lose water, then your blood pressure will go down; it will stay down consistently. That is why many people with low blood pressure tend to do better when they eat more salt they can be perked up and feel much better. But of course, you have to be careful because too much salt can lead to another set of problems including hypertension, as well as swelling in the legs, what we call edema. So first we have to understand that low blood pressure is a symptom and not a disease. Number two you have to look at the big picture of how everything else comes together. In an adrenal fatigue situation, oftentimes low blood pressure does not stand alone; it comes along with other clinical signs and symptoms that you have to put the pieces together. It is one of many symptoms that presents itself. Usually the more advanced the adrenal fatigue the more prominent this is. A very interesting thing that you also have to understand is that in the early stages of adrenal fatigue, blood pressure tends to rise because of the vessel constriction of blood vessels narrowing as a result of hormones; and then in later stages it tends to go down. So if you look at the blood pressure, it can be high and still have adrenal fatigue in early stages, if it stays low consistently then it could mean the body is in a state of advanced adrenal fatigue if all other medical workup is normal. So, low blood pressure constistently is an important symptom to look for in adrenal fatigue and it points us to the underlying dysfunction that is maybe happening in the adrenal glands.

Help us Improve our content Support us on Patreon : https://www.patreon.com/medsimplfied The renin–angiotensin system (RAS) or the renin–angiotensin–aldosterone system (RAAS) is a hormone system that is involved in the regulation of the plasma sodium concentration and arterial blood pressure.

Plasma renin then cuts a short, 10 amino acid long, peptide off a plasma protein known as angiotensinogen. The short peptide is known as angiotensin I.[2] Angiotensin I is then converted, by the removal of 2 amino acids, to form an octapeptide known as angiotensin II, by the enzyme angiotensin-converting enzyme (ACE) found in the lung capillaries. Angiotensin II is a potent vaso-active peptide that causes arterioles to constrict, resulting in increased arterial blood pressure.[3] Angiotensin II also stimulates the secretion of the hormone aldosterone from the adrenal cortex.[3] Aldosterone causes the tubular epithelial cells of the kidneys to increase the reabsorption of sodium ions from the tubular fluid back into the blood, while at the same time causing them to excrete potassium ions into the tubular fluid which will become urine. RELATED TOPICS renin catalysis protein chemical compound organic compound endocrine system polymer blood pressure angiotensin enzyme Renin-angiotensin system, physiological system that regulates blood pressure Renin is an enzyme secreted into the blood from specialized cells that encircle the arterioles at the entrance to the glomeruli of the kidneys (the renal capillary networks that are the filtration units of the kidney). The renin-secreting cells, which compose the juxtaglomerular apparatus, are sensitive to changes in blood flow and blood pressure. The primary stimulus for increased renin secretion is decreased blood flow to the kidneys, which may be caused by loss of sodium and water (as a result of diarrhea, persistent vomiting, or excessive perspiration) or by narrowing of a renal artery. Renin catalyzes the conversion of a plasma protein called angiotensinogen into a decapeptide (consisting of 10 amino acids) called angiotensin I. An enzyme in the serum called angiotensin-converting enzyme (ACE) then converts angiotensin I into an octapeptide (consisting of eight amino acids) called angiotensin II. Angiotensin II acts via receptors in the adrenal glands to stimulate the secretion of aldosterone, which stimulates salt and water reabsorption by the kidneys, and the constriction of small arteries (arterioles), which causes an increase in blood pressure. Angiotensin II further constricts blood vessels through its inhibitory actions on the reuptake into nerve terminals of the hormone norepinephrine.

The dangers of low blood pressure
 
06:49
Most people worry about high blood pressure, and with good reason as it portends numerous health risks, such as the possibility of an increased risk of heart attacks and strokes. But… Low blood pressure brings a different set of problems, such as reduced brain function and increased mortality risk. If the upper or lower number deviates by more than 10 from 120/80, it pays to be aware low blood pressure may be affecting your health. Think of it like this. The function of your blood pressure is to push the blood out of your blood vessels by permeating out of them to the rest of the body. High blood pressure is often a compensatory response to something that is going on in the body. If you cover up the end response of your body you can get other symptoms. Such as, a very common side effect of blood pressure medications is brain fog or mental “unclarity”. Which really makes perfect sense. Your brain is now not getting the blood (or oxygen) it needs to function, which equals……uhhhhhhhh? What? As a side note I often find that in the elderly, if they have not taken care of themselves and their arteries are already starting to harden, this will lead to decreased permeability of the blood vessels. As a result, blood pressure goes up to compensate and get blood to the brain. If you lower blood pressure too much, you no think too much! ;-) Blood pressure pushes blood through about 100,000 miles of veins, arteries, and capillaries in the body, carrying oxygen, nutrients, immune cells, hormones, neurotransmitters, and other vital compounds. High blood pressure strains blood vessels. However, low blood pressure means not enough blood is getting to capillaries and tissues, particularly in your hands, feet, and brain. This deprives those tissues of sufficient oxygen and nutrients. You may have chronic nail fungal infections and cold hands and feet if so. These can also be signs of an immune system that is deficient as well. So it pays to check both. Adrenal fatigue as a cause of low blood pressure The most common cause of low blood pressure (other than taking blood pressure medications) in a functional medicine model is poor adrenal function. The adrenals are two walnut-sized glands that sit atop the kidneys. They produce stress hormones and help regulate blood pressure. Many people today suffer from adrenal fatigue due to chronic stress. Other causes of adrenal fatigue are poor diets, low blood sugar, chronic infections, gut problems, inflammation, and unmanaged autoimmunity — all stressors.

What is the Parathyroid Gland?

Take Dr. Berg's Advanced Evaluation Quiz: http://bit.ly/EvalQuiz Your report will then be sent via email analyzing 104 potential symptoms, giving you a much deeper insight into the cause-effect relationship of your body issues. It's free and very enlightening. Dr. Berg talks about the parathyroid hormone. This gland produces the parathyroid hormone (PTH). This hormone controls calcium, by increases it. It will rob the bone of calcium to keep normal levels of calcium in the blood. It will also convert the inactive vitamin D3 to active vitamin D3. Vitamin D helps absorb calcium by 20x in the blood. If the gland enlarges into a tumor, it can cause way too much calcium in the blood and rob too much calcium from the bone: causing 1. Osteopenia 2. Osteoporosis 3. Fractures 4. High blood pressure 5. Atrial fib 6. Kidney stones 7. Body Pain 8. Hypercalcemia (increases urination, thirst, depression, etc.) To the best was to rule this out is to get a simple blood test - blood calcium test to see if it's high or not. Also test your PTH levels as well as your vitamin D levels (both inactive and active forms).

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. Blood pressure is the force the circulating blood EXERTS on the walls of blood vessels. It is different in different types of vessels, but the term ”blood pressure”, when not specified otherwise, refers to ARTERIAL pressure in the SYSTEMIC circulation. When the heart contracts and pumps blood into the aorta, during systole, the aortic pressure RISES, and so does the systemic arterial pressure. The maximum pressure following an ejection is called the SYSTOLIC pressure. In between heart beats, when the ventricles refill, blood pressure FALLS to its lowest value called the DIASTOLIC pressure. THESE are the 2 numbers on a blood pressure reading. Blood pressure normally shows a daily pattern and is usually lower at night. During day-time, it fluctuates with physical activities and emotional states. Hypertension refers to a PERSISTENT HIGH blood pressure. In the US, high blood pressure used to be defined as greater than 140/90, but recent guidelines have changed these values to 130/80 to better prevent and treat the condition. Normal blood pressure is BELOW 120/80. In practice, blood pressure is considered TOO low ONLY if it produces symptoms. Hypertension does NOT cause symptoms on its own, but it slowly DAMAGES blood vessels, and in the long-term, is a MAJOR risk factor for a variety of cardiovascular diseases such as stroke, aneurysm and heart attack; as well as end organ damage such as renal failure or vision loss. For this reason, hypertension is known as the “SILENT killer”. Hypertension can be classified as primary or secondary, with the former being responsible for over 90% of cases. Primary hypertension has NO apparent cause and may develop as a result of old age, obesity, high-salt diet, lack of exercise, smoking and drinking. Most commonly, the blood vessels are hardened with age or unhealthy diets, making it harder for blood to flow. Secondary hypertension, on the other hand, is caused by an underlying condition. Many conditions and factors can cause hypertension; most notable are kidney problems and endocrine disturbances. Regardless of the cause, the INcrease in blood pressure is produced by EITHER an INcrease in vascular resistance - narrower or stiffer blood vessels; OR an INcrease in cardiac output – larger volume of blood pumped out by the heart. These 2 factors are the targets of antihypertensive drugs. Treatments must start with life style changes such as healthy, low-sodium diets, physical exercise and stress management. On top of that, antihypertensive agents may be used to control hypertension. These include: - Vasodilators: these drugs DILATE blood vessels, thereby DEcreasing vascular resistance and reducing blood pressure. - Diuretics: diuretics promote sodium and water removal by the kidneys and thereby DEcrease blood volume. - Drugs that DEcrease cardiac output by decreasing heart rate or contractility, may also be used to treat hypertension.

Thyroid Hormone Regulation and Negative Feedback
 
03:18
In humans and other mammals, thyroid hormone regulates bioenergetics; helps maintain normal blood pressure, heart rate, and muscle tone; and regulates digestive and reproduc- tive functions. If the level of thyroid hormone in the blood drops, the hypothalamus responds by initiating a hormone cascade pathway . The hypothalamus secretes thyrotropin-releasing hormone (TRH), causing the anterior pituitary to secrete a tropic hormone known as either thyroid-stimulating hormone (TSH) or thyrotropin. TSH stimulates release of thyroid hormone by the thyroid gland, an organ in the neck consisting of two lobes on the ventral surface of the trachea. As thyroid hormone accumulates, it increases metabolic rate, while also initiating negative feed- back that prevents its overproduction. CAMPBELL 10th Edition

2-Minute Neuroscience: Hypothalamus & Pituitary Gland
 
02:01
In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I cover the hypothalamus and pituitary gland. I discuss the two major roles of the hypothalamus: homeostasis and hormones. I also explain how the hypothalamus controls hormone release by manipulating the pituitary gland. I cover the anterior and posterior lobes of the pituitary gland, along with the most common hormones secreted from each lobe. For more neuroscience articles, videos, and a complete neuroscience glossary, check out my website at www.neuroscientificallychallenged.com ! TRANSCRIPT: Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss the hypothalamus and pituitary gland. The hypothalamus is a small region situated directly above the brainstem. It is made up of a collection of nuclei with a variety of functions, but in general the hypothalamus is involved in controlling the two H’s: homeostasis and hormones. Homeostasis is a term used to describe the maintenance of balance or stability in a biological system. The hypothalamus can maintain homeostasis either by exerting direct influence over the autonomic nervous system, or by causing the release of hormones. The hypothalamus manipulates hormone release primarily by controlling the pituitary gland. The pituitary gland is a hormone-secreting gland that sits just below the hypothalamus. It is sometimes called the “master gland” because it not only secretes many extremely important hormones but it also regulates the activity of other hormone-secreting glands throughout the body. The pituitary consists of two lobes, called the anterior and the posterior pituitary. The anterior pituitary is responsible for the release of a number of hormones that have widespread effects throughout the body. They include growth hormone, which is involved with growth, follicle-stimulating hormone, which plays a role in development and reproduction, luteinizing hormone, which is essential to testosterone production and reproduction, adrenocorticotropic hormone, which is involved with the stress/fear response, thyroid sTimulating hormone, which is important to healthy metabolism, and prolactin, which promotes milk production in females. The release of these hormones is controlled by the hypothalamus, which sends signals in the form of releasing hormones to tell the anterior pituitary when to secrete its hormones. The posterior pituitary also secretes two hormones, but does not synthesize them. Instead, they are synthesized by the hypothalamus and then sent to the posterior pituitary for release into the bloodstream. The names of these hormones are: oxytocin and vasopressin. Oxytocin has important roles in facilitating childbirth and lactation, but is also thought to have a role in compassion and social bonding. Vasopressin's main functions are to control urine output and regulate blood pressure.

9 Reasons To Use Pink Himalayan Salt
 
06:22
9 Reasons To Use Pink Himalayan Salt The gorgeous hues of pink Himalayan salt makes it the perfect way to spruce up the table, yet this ancient seasoning has benefits that go far beyond beautifying your dining room. In fact, the rose-colored grains were once so valued for their transformative properties that they were used as currency by our ancestors. Today, this salt is used for everything from cooking to bathing and air purification, yet many people are still unaware of how much better it is for your health when compared to other salts. Although there are many different types of salt available, pink Himalayan salt is unique because it is the purest kind of salt you can find in the world. This is because the Himalayan salt beds were covered by lava millions of years ago. They then remained covered by snow and ice, which protected it from modern day pollutants. Now, the salt is hand-mined and brought to your table unrefined and unprocessed so that all of its beneficial properties are preserved. When compared to table salt, pink Himalayan salt has more nutritional value since it contains over 80 minerals, including bromine, zinc, calcium, potassium, phosphorous and boron. The larger grains also mean that you will get less sodium per serving from Himalayan salt than you would table salt since you need less to create the same level of flavor. Commercially prepared salt also goes through a process of bleaching and heating that destroys minerals, and it is treated with an anti-caking agent that builds up in our bodies and can cause health problems. When you have a choice between an all-natural seasoning with health benefits and one that has been processed beyond any recognition, the choice is pretty clear. However, here are just a few more reasons why using pink Himalayan salt will benefit your overall health. 1. Regulate Blood Sugar Out of the 84 minerals contained in pink Himalayan salt, there are four that play a major role in your body’s ability to regulate your blood sugar. These are chromium, manganese, vanadium and magnesium, which play an important role in the digestion of starches and sugars so that your blood sugar stays at healthy levels. 2. Stabilize Blood Pressure People are often advised to cut out table salt when they have high blood pressure due to the high sodium content. While pink Himalayan salt does have some sodium, it also contains the mineral potassium that can help lower blood pressure. 3. Stimulate Digestion When you add pink Himalayan salt to a meal, it helps the food move through the digestive track more easily. It also stimulates certain glands that are responsible for producing acid and enzymes in your stomach, liver and intestines. This can help you reduce post-meal discomforts such as bloating and constipation. 4. Breathe Freely When mixed with water to create an inhalable steam, pink Himalayan salt can relieve sinus congestion, bronchitis and asthma. Simply mix ½ cup of salt into one gallon of boiling water, and lean your face toward the bowl while keeping it safely away from the hottest part of the steam. Then, cover your face with a towel and inhale. You can do this as often as necessary to enjoy respiratory relief. 5. Replenish The Body’s Electrolytes Muscle cramps happen when you overtax your body and deplete it of water and essential minerals. Since Himalayan salt regulates your fluid levels and contains the minerals you need to replace, you will find that it relieves muscular pain quickly. Replenishing your electrolytes after exercise will also ensure that you enjoy more energy instead of a post-workout crash. 6. Relieve Menstrual Issues That monthly bloating and cramping does not have to be miserable anymore. Soaking in a pink Himalayan sea salt bath can ease water retention while soothing any lower abdominal cramping you experience. 7. Detox The Body Adding the pink salt to your bath water will also help with detoxification. This is because the compounds in the salt will break down sediment and toxins on your skin. Salt also draws out toxins from the deeper layers of your tissues so you can purify your body inside and out. 8. Increase Blood Circulation Pink Himalayan salt works to clear out your arteries, which can also help prevent the development of those dreaded varicose veins. Increasing blood flow to all of your body will also encourage better overall health while restoring your vitality. 9. Enjoy Restful Sleep The wonders of pink Himalayan salt can even continue to benefit your health well into the night. This is because it contains the trace minerals potassium and magnesium, which promote relaxation and an elevated mood. Just mix a teaspoon of the salt with several teaspoons of honey and allow a small amount to dissolve under your tongue. Not only will you fall asleep easier, but you will wake up refreshed and feeling all of the benefits of switching to pink Himalayan salt.

Cortisol: How to Balance Cortisol Levels to Burn Fat- Thomas DeLauer

Cortisol: How to Balance Cortisol Levels to Burn Fat- Thomas DeLauer… The Good and the Bad of Cortisol - http://www.ThomasDeLauer.com When you hear cortisol, you may automatically jump to stress and inflammation. There is more to cortisol than just functioning as a stress hormone. It is possible to have both too little and too much cortisol. So what exactly is cortisol and what does it do? Cortisol is a steroid hormone that is produced in the adrenal glands, with its secretion controlled by the adrenal glands, the hypothalamus and the pituitary gland. Most cells in the body have receptors for cortisol, so this hormone impacts much of your body in numerous ways. Cortisol functions include: Regulates blood sugar Regulates metabolism Plays a part in memory Impacts inflammation, including decreasing inflammation Blood pressure control Water and salt balance Supports a healthy pregnancy Proper cortisol function is in fact part of maintaining a healthy weight and losing fat. Slight elevations in cortisol levels activate an enzyme called hormone sensitive lipase (HSL). Burning fat involves hormones - HSL releases stored fat from your body when queued by cortisol. Your body is then able to utilize this fat for fuel, thus leading to fat burning.If your cortisol levels remain elevated for too long, the opposite can happen and cortisol will trigger fat storage. Excess cortisol causes: Chronic stress Cushing’s syndrome Excess cortisol can lead to: Weight gain, particularly around the core and face Mood swings Anxiety Depression High blood pressure Labido change Menstrual changes Chronic inflammation Too little cortisol causes (known as hypoadrenalism): Iron deficiency Long periods of excessive synthetic cortisol treatment (can reduce the natural release of cortisol) Addison’s disease - an autoimmune disease that can lead to adrenal gland damage Tuberculosis Other rare medical conditions Too little cortisol can lead to: Muscle loss and muscle fatigue Weight loss Fatigue Mood swings Dizziness Anxiety Difficulty sleeping Darkening of the skin What Can You Do? Controlling stress can help with both high and low cortisol levels, so adding meditation and yoga to your daily routine can help. Adaptogens such as ashwagandha can help to balance your stress response and cortisol levels. Research bomb: In a 2012 randomized, placebo-controlled study of 64 adults with chronic stress looked into the stress levels and serum cortisol levels following ashwagandha supplementation for 60 days. Those who took the Ashwagandha supplements were found to have lower serum cortisol levels when compared to the placebo group. Curcumin has also been shown to help reduce cortisol levels, so add turmeric to your foods. Speak with your doctor if you are experiencing any of the above symptoms. References: 1.

Simha means 'lion' and mudra means 'symbol'. The final position of this posture resembles like the face of the lion and so the name Simha Mudra. It improves the blood circulation in the throat region and so the health of thyroid and parathyroid glands improves. This practice stimulates carotid body and sinus nerves. This in turn helps to control blood pressure. Remember to do this practice alternately with jivha bandha for 3 times. www.yoboho.com

Why Do People With Acromegaly Have Hypertension?
 
02:30
Why Do People With Acromegaly Have Hypertension? There is one organ which causes high blood pressure (and it's not what you think!) and there are specific exercises you can use to target and fix your blood pressure easily. No diet, lifestyle changes or medication required: http://hibloodpressure.stream/ Answers from: Kristie Leong M.D. Youre absolutely right people with acromegaly have ahigher incidence of hypertension. Acromegaly is a condition where the portion of the brain called the pituitary gland produces too much growth hormone, usually due to a non-cancerous tumor of the pituitary gland. In one study, 42% of people who had acromegaly also had hypertension. What Causes Acromegaly, People who have acromegaly secrete too much growth hormoneas well as another related compound produced by the liver called IGF-1. Growth hormone and IGF-1 cause cartilage, bone, and other tissues to grow larger. As a result, people with acromegaly often experience joint pain, hand and feet swelling, joint pain, and enlarged facial features: Why is high blood pressure so common with this condition? Thetheory is that overproduction of growth hormone and IGF-1 causes the renin-angiotensin system to malfunction. This is a system at the level of the kidney that helps regulate blood pressure and fluid balance. When this happens, you begin retaining water and sodium and blood pressure goes. up. Another Reason Why Hypertension is More Common People with acromegaly can also develop insulin resistance and blood sugar abnormalities. As a result, people with this condition have higher levels of insulin in their bloodstream. This is another possible contributor to the elevation in blood pressure you see with acromegaly: The higher blood pressure places extra strain on the heart, particularly the left ventricle since it has to pump against tight arteries and more resistance. As a result, people with acromegaly can develop an enlarged left ventricle. So, heart disease is another complication of acromegaly: Hope this answers your question: References: Nature Reviews Endocrinology 1, 66 (December 2005) |doi: 10.1038/ncpendmet0037.

Adrenal Glands: Help Them Out By Slowing Down | Dr. Weston
 
03:40
Adrenal glands are teeny endocrine glands that sit at the top of the kidneys. The adrenal glands produce dozens of powerful hormones that help control heart rate, regulate blood pressure, and balance blood sugar levels. But what happens when good glands go bad? As much as 80% of the public are affected by adrenal fatigue, which is caused by constant stress, making the adrenal glands work improperly. Do you feel overwhelmed and exhausted? Do you have difficulty concentrating? Feel nervousness, anxiety, or depression? You too may have adrenal fatigue. So help those glands out by slowing down. Much like exercising without rest can cause muscle fatigue, being constantly on the go, go, go can cause adrenal fatigue. Eat whole foods rich in vitamins C, E, and B. Get adequate sleep. Cut down on alcohol, caffeine, and sugar. And, most important, take a breath, slow down, and don't overstress yourself. -- Subscribe to our channel: http://www.youtube.com/subscription_center?add_user=sunwarriortribe -- Visit us at: http://www.sunwarrior.com/ Like us on Facebook: http://www.facebook.com/sunwarrior ‪Follow us on Twitter: http://twitter.com/Sunwarrior Hang out with us on Google+: http://plus.google.com/100431369190586473063/posts Follow us on Pinterest: https://pinterest.com/sunwarriortribe/
