📝 Podcast Summary
The Power of Deliberate Cold Exposure for Mental Health and Physical Performance
Deliberate cold exposure can be leveraged to improve mental health, physical health, and performance. Temperature is a powerful stimulus on our nervous system and every organ and system of our body. It is important to understand how cold impacts the brain and body before applying specific protocols involving factors like temperature, duration, and delivery method. Consult a board-certified physician before initiating any protocol involving strong stimuli like changing temperature. Gradual progression is important, and extreme temperatures may not always be necessary for maximum benefits. The most potent stimulus isn't always the one experienced as most intense, and finding the minimum threshold of stimulus is crucial. Deliberate cold exposure has many powerful applications and can be complemented with other exercises like zone-two cardio for increased efficiency.
Boost Your Focus with Moderate Exercise Before Cognitive Work
Moderate exercise for just 15 minutes prior to cognitive work can significantly increase focus and attention. This is because exercise increases energy levels which directly impact cognitive performance. While mindfulness meditation is also beneficial, when given a choice between the two, moderate exercise could be more valuable. Non-sleep deep rest activities like SDR and yoga nidra also enhance neuroplasticity which can be done after the cognitive work. This protocol works every time and can be a great tool for mental and physical health performance. This study also showed that energy levels play a significant role in cognitive tasks and that exercise can help enhance visual attentional control and perceptual speed testing.
Using Deliberate Cold Exposure for Health & Performance
Deliberate cold exposure can be used as a tool for health and performance. However, it is important to keep in mind the baseline circadian rhythm in temperature, which varies across the 24-hour cycle. The circadian rhythm in temperature helps to frame both the effects of deliberate cold exposure and when to use it in order to access specific states. One should avoid using deliberate cold exposure during times within the 24-hour cycle when the primary goal is to get to sleep. Additionally, thermal regulation, meaning the brain and body's ability to regulate internal core temperature, is essential to maintain homeostasis. Thus, one should be mindful of how and where to place cold towels to avoid disrupting the body's natural thermostat.
Efficiently Regulating Body Temperature for Optimal Performance and Wellness.
Understanding how to regulate body temperature efficiently and effectively can improve athletic and cognitive performance and prevent hyperthermia. To quickly cool down, it's important to focus on cooling the upper half of the face, palms of the hands, and bottoms of the feet which have unique vasculature called arterial, venous anastomosis. Simply using a towel or splashing water on the body's surface can be ineffective and even counterproductive for lowering core body temperature. Deliberate cold exposure protocols have been shown to improve mental performance and resilience during times of stress. It's important to understand the role of adrenaline and noradrenaline in stress and use cold exposure as a tool for regulation.
The Benefits of Deliberate Cold Exposure
Deliberate cold exposure can increase the release of chemicals like dopamine, norepinephrine, and epinephrine which can improve mood, attention levels, and energy. This can be achieved by exposing oneself to a cold environment on purpose. The elevation in these chemicals is healthy and can lead to vast improvements in cognitive performance and energy levels. Deliberate cold exposure has also been shown to increase metabolism, convert white fat cells to beige or brown fat, and reduce inflammation. The mindset of deliberate cold exposure is key; being uncomfortable is a part of the process. The cold exposure protocols can be adjusted depending on personal preference and the intended outcome. Overall, deliberate cold exposure is a useful tool for training mental and physical resilience.
Efficient Ways for Deliberate Cold Exposure
When it comes to deliberate cold exposure, the most efficient way is to immerse yourself in cold water up to the neck with feet and hands submerged; however, a cold shower or exposure to cold air outside can also be beneficial. The key is to place yourself in an environment that is uncomfortably cold but safe to stay in. The temperature will vary depending on the individual's cold tolerance and core metabolism. Cold exposure has been shown to improve mental and physical performance, but there are no simple prescriptive guidelines for how cold the environment should be for maximum benefit. Individuals will have to experiment with different temperatures and times of the day to find what works best for them.
The Benefits of Deliberate Cold Exposure on Mental and Physical Performance
Deliberate cold exposure can increase mental and physical performance by stimulating the release of noradrenaline and adrenaline in the brain and body, which builds resilience and mental toughness. Cold showers, immersion, or wearing ice packs can be used to intentionally stress the body and increase these hormones. One simple protocol to increase resilience is to pick a temperature of uncomfortable cold for a certain duration of time and systematically increase it over time. However, different people will experience varying levels of noradrenaline and adrenaline release when exposed to cold, so it's important to monitor progress and adjust protocols accordingly. Cold exposure can help individuals maintain mental clarity and calm in stressful situations through deliberate stress and building resilience.
Building Mental Resilience Through Counting Walls.
Building mental resilience or grit can be achieved through protocols such as timed exposure to cold temperatures. One approach is to gradually increase duration or decrease temperature, but there is a limit to how low the temperature can go. A more effective approach is to build mental toughness by counting walls, which are moments when the sensation of discomfort arises. These walls can be set and progressively increased over time, giving flexibility and room for growth. By counting and traversing these walls safely, one can build resilience and resistance to stressors through willpower and cognitive control. This approach offers more latitude and adaptability to the individual compared to just focusing on time and temperature.
Using Cold Exposure to Build Resilience and Mental Toughness
To build resilience and mental toughness, vary the temperature and time parameters of cold exposure. Use these experiences to teach your top-down control to clamp down on reflex and learn behavioral control in the context of your body. When exposing yourself to cold, you can either try and calm yourself or lean into the challenge and grind it out. Anchoring your mind in cognitive activities can help maintain clarity of thinking and learn to do so when the body is flooded with stress chemicals. Cold exposure can train you up for real-life stressors and help you climb walls of resistance while staying calm and clear of mind.
Increase Cognitive Performance with Deliberate Cold Exposure
Deliberate cold exposure can increase cognitive performance by teaching the brain to stay engaged under high stress levels. Toggling between different states of mind like boxing and chess or doing cognitive tasks in an ice bath can help increase cognitive clarity and resilience through stress. Moving around in cold water immersion can increase the potency of the stimulus as stillness generates a thermal layer that generates heat, making the body warmer. It is recommended to do 11 minutes total of deliberate cold exposure per week, divided into two or four sessions of two or three minutes. This threshold is geared towards increases in metabolism and can be a good number to use for most people.
The Power of Deliberate Cold Exposure for Mental Toughness and Health
Deliberate cold exposure can help build mental toughness, but it should be done safely and consistently. Andrew Huberman recommends getting at least 11 minutes of exposure per week, but adjusting the frequency, duration, or temperature if it becomes too easy. Cold exposure can also release dopamine, which can improve mood, energy, and focus. This makes it a healthier dopamine release for those struggling with addiction. Most stressors only increase norepinephrine and epinephrine, but deliberate cold exposure seems to cause a dramatic increase in dopamine, as seen in a 2000 study. Therefore, deliberate cold exposure may be a powerful tool for building resilience and improving mental health and focus in the long run.
The Benefits and Risks of Cold Exposure and Exercise on Metabolism, Hormones, and Mental Acuity
Extended exposure to moderately cold water, even at temperatures not considered very cold, can lead to dramatic increases in metabolism and serum levels of norepinephrine, dopamine, and cortisol in the blood. Deliberate cold exposure is known to create similar increases in dopamine that are long lasting and can enhance mental acuity and the ability to focus. These effects of deliberate cold exposure are similar to those of addictive drugs, but can be leveraged towards other activities. However, the optimal duration and temperature for cold exposure is unknown and should be done safely. Short 15 minute exercise at moderate intensity can also increase levels of energy and mental acuity.
Benefits of Deliberate Cold Exposure for Mental and Physical Health.
Deliberate cold exposure can increase catecholamines such as nor epinephrin and dopamine which sharpen mental acuity, elevate mood and improve levels of alertness in the short term. It can also create use stress by stressing the brain and body without increasing cortisol, leading to positive health outcomes. Additionally, deliberate cold exposure has significant metabolic benefits, including increases in brown fat thermogenesis, core body temperature and metabolism by changing the types of fat stored in our body. Regular exposure to cold environments can prepare our body for different seasons, but it is important to not push beyond the threshold of what our body can handle.
Deliberate Cold Exposure for Boosting Metabolism and Losing Weight.
Deliberate cold exposure can help convert white fat cells into more metabolically active and thermogenic beige and brown fat cells, thus increasing overall core metabolism. When we expose ourselves to cold environments on a repeated basis, our bodies become more comfortable in those environments. This is because norepinephrine released during cold exposure binds to receptors on the surface of white fat cells, triggering the release of UCP one and other factors that increase mitochondrial output and change gene expression in these cells. Though babies and young children have brown fat to keep them warm, adults tend to lose this over time. Deliberate cold exposure can help increase beige and brown fat stores, making us more comfortable and increasing our metabolism.
The Benefits of Deliberate Cold Exposure and How to Maximize Them.
Deliberate cold exposure can increase metabolism by converting white fat to beige or brown fat, leading to lasting effects. The increase in metabolism from cold exposure is not just limited to an increase in resilience, but it also enhances the effect of norepinephrine and epinephrine, especially during fasted states. Fasting and intermittent fasting can benefit from deliberate cold exposure, leading to a greater increase in norepinephrine and epinephrine. Combining caffeine intake before cold exposure leads to an increased density and efficacy of dopamine receptors. However, it is essential to balance these protocols with other activities, such as school or relationships.
Using Cold Exposure and Coffee to Increase Dopamine and Metabolism
To get the effects of dopamine, the receptors need to be available in the appropriate density, in the striatum. Ingesting coffee an hour before an ice bath may be beneficial to increase dopamine over extended periods of time. To achieve the greatest increases in metabolism through deliberate cold exposure, follow the sober principle and force yourself to reheat naturally after the cold exposure. Shivering due to deliberate cold exposure causes the release of a molecule called irisin, which plays a key role in activating brown fat thermogenesis, critical to increases in metabolism. To efficiently induce shivering, alternate one to three minutes of cold exposure with one to three minutes of drying out in the air, and repeat. This can be a brutal protocol, but can increase metabolism.
The Effects of Deliberate Cold Exposure on Metabolism and Fat Cells
Deliberate cold exposure can induce increases in metabolism in both the short-term and long-term, and can cause fat cells to convert to BeiGene brown fat. Neurons that sense cold can release nor epinephrine into the fat cells which results in gene expression changes with huge cascades of immediate and long-term effects. Cold exposure should be avoided up to four hours after hypertrophy and strength training if those are the main goals, but cold water immersion after endurance or skill training will not inhibit progress or the stimulus that leads to progress during the training. It is not necessary to end on cold or induce shivers, but if the primary goal is to induce weight loss through metabolism, ending on cold and finding a safe way to shiver is recommended.
The Benefits of Cold Water Immersion After Exercise
Cold water immersion performed after high intensity exercise can significantly improve recovery, reduce soreness, and improve training efficacy. Shorter duration cold exposure is also effective, with durations of one to five minutes at lower temperatures being ideal. Cold immersion can positively impact muscular power, reduce muscle soreness, and improve perceived recovery. This approach is more effective than passive recovery from various standpoints. However, eccentric exercises may not benefit from cold immersion. Therefore, unless the goal is hypertrophy and strength, immediate cold exposure, preferably cold water immersion or ice baths, can be beneficial after training, especially high-intensity training.
The Benefits of Deliberate Cold Exposure on Glamour Skin Surfaces
Deliberate cold exposure, like taking cold showers or immersing in cold water, can help reduce inflammatory cytokines and increase anti-inflammatory cytokines, making it an effective anti-inflammatory tool. Cold exposure on glamour skin surfaces like palms, upper face, and soles of feet is efficient in cooling the body, and can even save lives in cases of exercise-induced hyperthermia. However, it's important to use cool objects or surfaces that are not too cold to cause vasoconstriction of the veins in those areas. Dr. Craig Heller and colleagues have developed a commercial product called the cool mint, a glove that circulates water at a temperature that won't cause vasoconstriction of the palm. Glamour skin cooling can improve performance and help offset hyperthermia.
The Promising Benefits of Palmer Cooling for Physical Performance
Palmer cooling, or cooling the palms of hands, is a promising way to improve endurance and strength training output. Cooling the body through this method can lead to significant increases in physical performance. The effects of Palmer cooling tend to be on the ability to do more work over time, rather than short, immediate bursts of activity. It is important to note that Palmer cooling should be done correctly and in conjunction with proper exercise protocols. The benefits of Palmer cooling are clear and robust, allowing people to go longer with less perceived effort and to quit later. This method is a promising area of research for those looking to improve their physical performance through innovative means.
The Power of Palmer Cooling for Increased Endurance and Strength
Palmer cooling, i.e., using a relatively cool object to cool the palms or the bottom of the feet for a minute or two in between sets, can vastly increase endurance and strength volume by reducing core body and muscular temperature. This can help in pushing through plateaus and reducing delayed onset muscle soreness. This technique can work well for experienced athletes as well and can be used when people reach plateaus in endurance and strength training. The narrow range of temperatures under which muscles can perform is critical to muscle contractions, so cooling can increase the capacity for pyruvate kinase to allow muscles to contract and thereby allow more volume of endurance and strength training.
The Potential Benefits and Risks of Deliberate Cold Exposure to the Groin and Testicles
Deliberate cold exposure to the groin and testicles may increase testosterone, but there are no controlled studies to confirm this claim. The increased blood flow to the area due to vasoconstriction and vasodilation, as well as the dopamine increases caused by cold exposure, are the two plausible mechanisms that may stimulate testosterone production. However, applying ice packs directly to the gonads is not necessary and may even be dangerous. It is also essential to consider that deliberate cold exposure can increase core body temperature, which is associated with wakefulness and alertness. It is important to be cautious and aware of these factors while using deliberate cold exposure to improve health and performance.
Deliberate Cold Exposure: Timing is Everything
Deliberate cold exposure can increase core body temperature and make you feel more alert if done properly. However, if done too late in the day, it can disrupt sleep by disrupting your core body temperature. Ideally, it should be done early in the day when most of us want to be alert. But, like Andrew Huberman, some people may also take it in the afternoon or even at night if they are prepared to be fairly alert for the next few hours. A decrease in core body temperature of one to three degrees is necessary for deep sleep. Therefore, if you want to get into deep sleep and remain in it, deliberate cold exposure done properly in the right time will help you achieve that.
