Why & How Intermittent Fasting Increases Growth Hormone

Intermittent fasting is a pattern of eating where you cycle between periods of fasting and eating. During the fasting periods, you do not eat or drink any calorie-containing foods or beverages. These periods can range from 12 hours to 24 hours or more. The eating periods can vary from one meal to several meals per day. Intermittent fasting has been shown to increase levels of growth hormone by binding ghrelin to the growth hormone releasing hormone receptor. This can lead to increased fat burning, improved muscle and general tissue health, and increased metabolism.

Why Your Stomach Growls

Your stomach growls because of the smooth muscle that lines it. When you eat or drink, your stomach cinches off at the two ends, and the muscles that line the sides of your stomach churn the food. If you don't have any food in your stomach, the churning continues, which causes the stomach growling.

Hot Baths & Hormones

Sauna, controlled safe hyperthermia can cause huge increases in growth hormone release anywhere from 300 to 500, even 1600% increases in growth hormone release. This is because when the Body is heated, it releases growth hormone in order to try and cool itself down. However, the temperatures that are needed to increase growth hormone are so high that there is a risk of burns. Therefore, saunas are the best way to increase growth hormone safely.

Energy, Adrenaline (Epinephrine), & Cortisol

Cortisol and epinephrine are two hormones that are responsible for a person's energy levels and immune system function. Most people want their energy levels to be high during the day and taper off at night, and they don't want to get sick. Therefore, these two hormones are very important in regulating a person's health.

Cortisol & Cholesterol, Competition With Testosterone & Estrogen

Cortisol is a steroid hormone that is derived from cholesterol. It is a precursor molecule for things like testosterone and estrogen. Cortisol is a competitive partner to estrogen and testosterone. This means that no matter how much cholesterol you are eating or producing, if you are stressed, more of that cholesterol will be devoted toward creating cortisol. Cortisol is a Stress hormone that is important for immune system function, memory, and preventing depression. However, it is important to control the timing and level of your cortisol so that it is not too high or too low.

Adrenaline (Epinephrine) Is Your (Immune Systems) Best Friend

Epinephrine is a hormone that is released in response to stress. It is often referred to as the "fight or flight" hormone because it prepares the body for physical activity. Epinephrine can have both positive and negative effects on the body. For example, epinephrine can help to improve memory and learning. It can also help to protect the body from infection. However, epinephrine can also cause anxiety and other stress-related symptoms.

Cortisol Basics In Two (Actually 1) Minute/s

Cortisol is a hormone that is produced in response to stress. It is sometimes referred to as the "stress hormone" because it helps the body to deal with stressful situations. Cortisol is produced by the adrenal glands and is released into the bloodstream. It works to increase blood sugar levels and to make the body more alert.

Adrenaline Basics In Two Minutes

The body's stress response is a complex system involving many different hormones and organs. When the body senses a stressor, whether it be physical or mental, a signal is sent to the sympathetic chain ganglia. These neurons release norepinephrine, which is like a sprinkler system that hoses the body with epinephrine. This increases heart rate, breathing rate, and blood flow to the vital organs. It also constricts blood vessels and makes the extremities cold. Adrenaline is also released from the adrenals, which are located on top of the kidneys. This creates alertness in the brain.

Tool: Time Your Cortisol Peak To Waking Using Specific Light Intensities

Cortisol is a hormone that helps to regulate energy levels, and epinephrine is a hormone that helps to regulate stress levels. When these two hormones are in balance, it helps to improve focus, energy levels, and learning. However, when cortisol levels are too high, it can lead to anxiety and depression. One way to help regulate cortisol levels is to get outside and view some sunlight within the first hour after waking up. This helps to stimulate the release of cortisol at the appropriate time, which can improve mental state and overall health.

Brief Increases In Cortisol & Adrenaline Boost Energy, Focus & Immunity

Cortisol is a hormone that is released in response to stress. It increases alertness and attention and can help to mobilize the body towards a goal. However, if cortisol levels become too high or are experienced chronically, it can lead to negative effects such as anxiety, irritability, and difficulty sleeping. NSDR, or non sleep deep rest, is a protocol that can help to reduce cortisol levels and improve sleep.

Ways To Increase Adrenaline, Epinephrine & Cortisol & Why That Is Good

The body releases stress hormones like epinephrine and cortisol in response to stressors like a troubling text message, an ice bath, or high intensity interval training. These stress hormones can have either positive or negative effects on the body, depending on how often they are released and when they are released. To avoid the negative effects of too much stress, it is important to deliberately increase epinephrine and cortisol levels in a way that is beneficial to the body.

Does Mindset During Stress Matter?

When you tell yourself that you're enjoying something or that it's good for you, it helps to release dopamine and serotonin which can help to buffer the epinephrine response. This is because dopamine is the precursor to epinephrine, and cortisol is made from cholesterol. Telling yourself that you're enjoying something can help to increase the release of epinephrine, giving you a sense of control.

Protocols: Adrenaline Breathing Described

If you want to increase your energy levels, you can do things like take an ice bath, take a cold shower, or do a breathing exercise where you inhale and exhale deeply 25-30 times. They say that doing these things will release adrenaline and norepinephrine in your body, which will make you more alert. They also say that you can follow the breathing exercise with an exhale hold, where you hold your breath for 15-30 seconds. They say that doing these things will help you to better buffer the stress response when you experience it from life events.

Practices To Increase Energy Without Increasing Stress

In order to increase energy and focus, and to improve the function of the immune system, it is important to be able to release adrenaline from the body on demand. One way to do this is through a cold shower or a breathing protocol. The key is to try to stay calm in the mind while the body is in a heightened state of alertness. This allows the body to enter a state of readiness and alertness while the mind remains calm.

Using Stressors to ENHANCE Our Immune System: Science & Tools

The body's stress response is governed by the sympathetic nervous system, which is responsible for the "fight-or-flight" response. This response is characterized by increased heart rate, increased respiration, and increased blood flow. When the body is under stress, levels of epinephrine (also known as adrenaline) and cortisol are increased. These hormones are responsible for the body's stress response, and they have been shown to improve immune system function in the short term. In a study published in the Proceedings of the National Academy of Sciences, it was shown that brief bouts of stress (induced by breathing exercises) can attenuate the negative effects of E. coli infection. This suggests that the sympathetic nervous system can be used to control the body's response to stress and infection.

Timing Thyroid Release For Energy

The body's release of the hormone cortisol is controlled in part by the body's circadian mechanisms. Cortisol is responsible for setting the level of metabolism, and it is also responsible for timing the release of thyroid hormone. Getting cortisol exposure early in the day can help to increase energy levels and to properly time the release of thyroid hormone.

Adrenaline/Stress Increase Performance & Memory. IF They Are After Learning

epinephrine (adrenaline) and cortisol (the stress hormone) can actually improve learning and memory, as long as they are not too high. This is because these hormones help to consolidate memories and make them more robust. However, it is important to note that this only works if the hormones are released after the learning has taken place – if they are released before, they can actually interfere with learning.

An Optimal Learning Protocol

The optimal strategy for enhanced learning would be to focus for 90 minutes, followed by a cold shower or tummo type breathing, or ice bath. Then shower up and do a non sleep deep rest, and finally get a good night's sleep.

Coffee Changes Your Brain & Increases Connectivity Of “Anxiety Circuits”

The study found that people who drink coffee habitually every day have changes in their brain circuitry that bias toward anxiety, even when they don't ingest caffeine. This means that the anxiety is not just from the caffeine in the coffee, but from the way that chronic coffee drinking changes the brain's circuitry.

Nootropics: Two Kinds, & How & Why They Work, “Neural Energy”

Nootropics are drugs that people take to increase their cognitive abilities. They fall into two categories: those that increase blood glucose, and those that increase cholinergic system activity. Both have their benefits and drawbacks.

Cortisol and epinephrine are two hormones that are associated with increased energy. However, if they are chronically elevated, they can have negative impacts on the body, including insomnia and compromised immunity.

Biology of Comfort Foods: From Negative to Positive Feedback Loops

Cortisol, a stress hormone, can cause increased appetite for high-fat and high-sugar foods, a phenomenon known as "comfort eating." This is because chronic stress can cause a positive feedback loop between the adrenals and the brain, resulting in increased production of cortisol. This can lead to health problems such as type 2 diabetes and anxiety. Therefore, it is important to learn to manage stress in order to maintain a healthy lifestyle.

Bombesin: Energy Without Eating

Short-term stress can actually block hunger by activating or interacting with a system called the bombesin system. Bombesin is a peptide hormone that was named after some sort of reptiles or amphibians, excuse me, some sort of toad. Toad's Latin name is Bombina bombina, or something of that sort. And so they decided to call this thing bombesin, but it reduces eating and stress liberates bombesin and makes you want to eat less. But chronic stress causes all these positive feedback changes, which are not positive.

How Stress Makes Our Hair Gray, & How To Prevent Stress-Induced-Graying

Stress has many negative effects on the body, one of which is premature graying. Gray hair is caused by a depletion of melanocytes, which are responsible for pigmentation. Stress can deplete melanocytes stem cells, causing the hair to go gray. To offset the effects of stress on graying, it is important to have a practice to regulate stress, and to get ample sunlight.

Blunting Chronic Cortisol, Including: Ashwagandha & Science Of

Chronic stress is when the body is in a state of stress for an extended period of time. This can be due to many things such as a demanding job, a chaotic home life, or financial problems. When the body is in a state of chronic stress, it has a negative impact on the person's health. This is because the body is constantly producing stress hormones, which can lead to problems such as high blood pressure, anxiety, and depression. There are ways to help reduce chronic stress, such as exercise, relaxation techniques, and supplements.

Ashwagandha is a common supplement with a powerful effect on anxiety. It has been shown to modestly increase testosterone and reduce LDL cholesterol. It also has a profound effect on cortisol, with a reduction of 14.5 to 27.9% noted in studies. Ashwagandha may also improve memory and decrease reaction times.

Licorice Increases Cortisol & Blood Pressure, & Reduces Testosterone (by Glycyrrhizin)

So some substances can increase cortisol levels, which in turn can decrease estrogen and testosterone. This can have an impact on blood pressure and other stress hormones. Liquorice is one such substance, and it can be used in small amounts to help with things like jet lag. However, it is important to be careful not to overuse it, as too much cortisol can have negative effects.

Apigenin: Anti-Cortisol

Apigenin is a compound found in chamomile that has various effects, one of which is reducing anxiety. It is believed to work by calming the nervous system. Ashwagandha and Apigenin together are considered to be the most potent commercial compounds for reducing chronic stress.

Protocols For Optimizing Energy & Immune System Function (& Learning)

Cortisol and epinephrine are hormones that have both positive and negative effects on the body. If levels are too high for too long, it can lead to chronic stress and negative health effects. However, if levels are managed and maintained at a healthy level, it can lead to increased alertness and energy. Fasting is one way to increase levels of these hormones in the short term.

When Fasting, Exercise, Cold & Intense Breathing Become Detrimental

If you are experiencing a lot of stress in your life, and you are also fasting, you are putting yourself at a greater risk for more chronic stress. This is because fasting can lower your testosterone and estrogen levels, and also affect your sleep and immune system. However, if you are feeling low energy, then practices like ice baths and intense breathing may be beneficial. But if you are feeling exhausted and burnt out, then fasting or doing a lot of cold exposure is not going to help and may actually make things worse.

Prescription Compounds

There are drugs that can be used to treat conditions that involve high or low levels of cortisol, but that these drugs come with their own risks and side effects. The speaker emphasizes that it is important to speak to a medical professional before starting any kind of treatment.

Tools For Accessing Alert & Calm States of “Energy”: Separating The Brain & Body

It is beneficial to have a practice of increasing adrenaline in your body while learning to stay calm in your mind. This helps to separate the brain body experience. Most of the negative effects on your life are due to people being unable to regulate their mind when they have high levels of adrenaline in their body. The ability to regulate adrenaline cortisol is about inducing them deliberately when you want to push back on infection, potential infection from bacteria viruses. It is about training your system to have a deliberate dissociation between the adrenaline response from the adrenals and the adrenaline response from the brainstem.

Ways To Apply Knowledge Presented Today

The information covered in today's episode is designed to help the listener understand how to better control their stress levels by regulating the hormones cortisol and adrenaline. It is important to remember that these hormones are not inherently good or bad, but rather it is the chronic stress that they can cause that is problematic. The listener is encouraged to take what they have learned and apply it in their own life to improve their stress management.
