Heat: The Enemy of All Performance (& Why)
Heat: The Enemy of All Performance (& Why)
Temperature has a significant impact on the body's ability to perform and learn new skills. The body has evolved mechanisms to maintain a narrow range of temperatures, as overheating can be detrimental to physical performance and tissue health. Hyperthermia, or excessive heat, can cause neurons to die in the brain, leading to a loss of function. Additionally, heat can modify the structure of enzymes, which are essential for cellular function and energy generation. Therefore, the body has built-in mechanisms to prevent overheating and maintain optimal temperature for optimal performance and health.
Key Points:
- Heat can negatively impact performance and recovery by impairing digestion, cognitive function, and cell survival.
- Maintaining an optimal temperature range is crucial, as excessive heat can be detrimental.
- Cooling can be beneficial and offers more flexibility in terms of performance enhancement.
Blood Flow & Sweating & Piloerection
The body regulates temperature through vasoconstriction and vasodilation of blood vessels. When cold, blood vessels constrict, preserving heat in the core. When hot, blood vessels dilate, allowing more blood flow to the periphery and causing sweating. Different animals have varying capacities to sweat, using alternative methods like spitting or panting.
Key points:
- Sweating is a mechanism to cool down the body, but it is less effective in humid conditions.
- Vasodilation and vasoconstriction also help regulate body temperature.
- Goosebumps, or piloerection, are a leftover response from when humans had more body hair.
- Adrenaline is released in response to cold temperatures, causing hair follicles to stand up.
- Hair can be used by animals like Malamutes or Huskies to regulate body temperature.
Understanding vasoconstriction, vasodilation, sweating, and fluid conservation is important for leveraging temperature for physical performance and maintaining and dumping heat.
Heat Is What Limits Effort: Even If You Feel Fine/Motivated
Heat is a major limiting factor in exercise performance, affecting the ability of muscles to contract. The optimal temperature range for muscle contractions is narrow, around 39-40 degrees Celsius. If muscles get too hot or too cold, they fail to generate contractions, leading to decreased exercise capacity. Maintaining the proper temperature range is crucial for maximizing performance. Cooling technology is being used to overcome the barrier of elevated heat and improve workout performance, with striking results.
Key points:
- Heat affects muscle contractions and decreases exercise capacity
- Optimal temperature range for muscle contractions is around 39-40 degrees Celsius
- Cooling technology is used to maintain proper temperature range and improve performance
- Cooling technology has been successful in professional sports teams, the military, and other professions.
Proper Cooling Can Double, Triple, Quadruple (Or More) Your Ability
- Proper cooling techniques can greatly enhance exercise performance and recovery.
- A professional athlete experienced a threefold increase in the number of dips in less than a week through the use of proper cooling.
- The benefits of proper cooling extend beyond just strength training, also improving endurance running.
- The specific methods of proper cooling were not mentioned in the summaries.
Heat Induced Confusion & Death
Heat-induced confusion and death can occur when the body overheats, leading to severe danger such as hyperthermia. This can be caused by certain dietary supplements or drugs that increase body temperature, as well as dehydration and head injuries in professional combat sports. Additionally, drugs like MDMA can impair the body's ability to regulate temperature. During intense exercise, our muscles can overheat, triggering a self-preservation mechanism that may not activate in time, resulting in potentially fatal consequences. Proper heat dissipation is essential for prolonged and safe performance during exercise.

The Three Body Parts Best For Heating & Cooling Your Whole Body
- The body has three main compartments for regulating temperature: the core, the periphery, and a third component consisting of the face, palms of the hands, and bottoms of the feet.
- These areas are highly effective at passing heat out of the body and bringing cool into the body.
- They allow for rapid heating or cooling of the entire body.
- This knowledge can greatly enhance exercise performance and recovery.
Face, Palms, Bottoms of Feet; Glabrous Skin
- The unique vasculature of glabrous skin in the face, palms of hands, and bottoms of feet lacks hair and has a distinct arrangement of blood vessels, capillaries, and arteries.
- This specialized vasculature allows for efficient heat dissipation and cooling.
Arterio-Venous Anastamoses (AVAs) Are Super Cool(ing)!
Arterio-Venous Anastomoses (AVAs) are specialized blood vessels that allow for increased flow of heat and cooling in the body. They are direct connections between small arteries and small veins, bypassing capillaries. AVAs have a large inner diameter and a thick muscular wall. They receive input from adrenergic neurons, allowing them to contract or dilate. AVAs play a role in regulating heat and cooling in the hands, feet, and face.
Key points:
- AVAs are found in the hands, feet, and face
- They bypass capillaries and have a large inner diameter and thick muscular wall
- AVAs can contract or dilate based on input from adrenergic neurons

Increasing Endurance, Willpower & Persistence
Increasing Endurance, Willpower & Persistence
- Cooling the body during exercise can increase the number of reps and sets that can be performed with the same weight.
- Endurance can be improved through cooling, as excessive heat can cause the body to shut down.
- Body heat and willpower are physiologically linked, and maintaining a cool body temperature can help individuals push themselves further.
- The reflex that connects the body and brain shuts off effort when the body becomes too hot.
- Laboratory tests have shown that participants can maintain effort on a treadmill when they are not pushed to the point of exhaustion.
Cardiac Drift, & Moving the ”I Quit” Point
Cardiac drift, the increase in heart rate during exercise in a hot environment, can lead to fatigue and decreased performance. Cooling the body, particularly the hands and face, can counteract cardiac drift and improve exercise performance. Cooling not only allows individuals to go further and faster for longer periods of time, but also protects against overheating and potential harm to the brain and body. Cooling has been shown to significantly increase work output, with individuals able to perform six times more pull-ups when cooled compared to controls. Additionally, cooling can enhance mental willpower and the perception of being able to do more work.
Deliberate Heating: Myths and Better Protocols
The most profound aspect of the text is the importance of cooling the palms, feet, and face for optimal heat transfer in the body.
Key points:
- The palms of the hands, the bottoms of the feet, and the face are key areas for heat loss and regulation.
- Most heat actually escapes through these areas rather than the head.
- Warming the palms, feet, and face is recommended for insulating heat loss.
- The use of warm socks on the feet is mentioned as an effective method for heating up post-surgery patients.
- The use of gloves on the hands and warming the face, without obstructing respiration, is recommended.
Protocols For Self-Directed Cooling To Vastly Improve Performance
Self-directed cooling can greatly improve exercise performance and recovery. Here are the key points:
- The most effective areas to cool are the face, palms, and bottoms of the feet.
- Cooling the core, such as with an ice bath, is not as effective.
- Cooling devices for bike handles are being developed.
- Cooling the hands or feet in cool water for 10-30 seconds between sets or during fatigue can provide benefits.
- Cooling the face can help dissipate heat and improve output.
- Ice packs can be used to quickly dump heat.
- Cooling the hands, feet, and face can lead to improvements in endurance, strength, and explosive power.
- Cooling these surfaces does not require precise temperature control.
- Cooling the hands and bottoms of the feet can result in a significant increase in performance.
- These surfaces can also be used to heat up in certain situations.
How To Use Cold To Recover Faster & More Thoroughly
Cold can greatly improve exercise performance, endurance, and strength, as well as enhance recovery. To optimize the benefits of cold, it is important to cool specific areas of the body such as the face, palms of the hands, and bottoms of the feet. Submerging the body in an ice bath or taking a cold shower is not as effective because it does not target these key areas and can cause vasoconstriction. Instead, methods like ice baths, cold showers, or ice packs on the back of the neck can be used to cool specific surfaces without causing vasoconstriction.
Ice Baths & Cold Showers Can Prevent Training Progress: mTOR, etc.
Ice baths, cold showers, and cryotherapy may hinder muscle growth and adaptation by blocking pathways involved in muscle hypertrophy, such as mTOR. However, cooling specific regions like the face, palms, or feet can still be beneficial for recovery without inhibiting muscle growth. Endurance work has not been extensively studied, but targeted cooling is recommended over full-body immersion. Cooling the body back to its resting temperature after a workout can enhance muscle and tendon recovery, allowing for quicker return to training. Focusing on cooling the palms, bottoms of the feet, or face is recommended for optimal results.
Alcohol, Caffeine, NSAIDs: Their Temperature Effects Matter
Maintaining an optimal body temperature is crucial for maximizing exercise performance and optimizing recovery. Here are the key points:
- Certain substances like caffeine and thermogenic compounds can increase body temperature before exercise, limiting performance.
- Alcohol, being a vasodilator, can lower body temperature and potentially aid in recovery.
- Consuming alcohol after exercise should be avoided by those with alcohol-related issues or who are underage.
- Anything that increases body temperature after exercise hinders recovery, while anything that lowers body temperature within safe ranges accelerates recovery.
- Compounds like caffeine and NSAIDs can increase body temperature and impede recovery.
Are Stimulants Counter Productive For Performance? It Depends.
Stimulants, such as caffeine, can hinder exercise performance despite providing an initial boost of energy. The increase in body temperature caused by these compounds can lead to decreased performance and hinder recovery. For individuals who are not using other methods to enhance recovery, such as hormone augmentation, the use of stimulants may be counterproductive for both performance and body recomposition goals.
Key points:
- Stimulants like caffeine can hinder exercise performance despite providing an initial energy boost.
- The increase in body temperature caused by stimulants can lead to decreased performance and hinder recovery.
- For individuals not using other methods to enhance recovery, such as hormone augmentation, stimulants may be counterproductive for performance and body recomposition goals.
- Stimulants can have both positive and negative effects on exercise performance.
- They can increase alertness and focus, but may impair recovery and increase heart rate.
- The impact of stimulants on performance depends on individual factors like genetics and tolerance.
- It is important to consider the potential drawbacks and benefits before using stimulants for exercise.
The Caffeine Rule & “Caffeine Adaptation”
Caffeine can have different effects on exercise performance and recovery depending on an individual's caffeine adaptation. For those who are not caffeine adapted or are caffeine sensitive, consuming caffeine before exercise can constrict blood vessels and increase body heat retention, which is not ideal. However, for those who are caffeine adapted, caffeine can cause vasodilation and help in dissipating body heat, making it beneficial to consume before exercise. It is recommended that individuals who regularly consume caffeine (2-3 cups of coffee or more per day) should consume it before exercise and avoid consuming it after exercise. On the other hand, individuals who do not consume caffeine should avoid consuming it before a workout as it can increase core body temperature and constrict blood vessels, making it harder to dissipate heat. Generally, it is better to avoid caffeine unless one is a heavy caffeine user or abuser, as abruptly stopping caffeine consumption can lead to headaches and decreased motivation. It takes about three weeks to adapt to no caffeine.

NSAIDs for Training: Performance Enhancements & Risks
Non-steroidal anti-inflammatory drugs (NSAIDs) such as Tylenol and Advil can lower body temperature and are often used by athletes, especially endurance athletes, to keep their body temperature lower during long bouts of exertion. Lower body temperature allows for greater endurance and intensity. However, NSAIDs can have negative effects on the liver and kidneys, and maintaining water and salt balance is crucial for optimal performance. Therefore, careful consideration should be given before using NSAIDs for performance enhancement, especially in situations where monitoring body temperature is important. Additionally, alcohol and caffeine can also impact performance and recovery, so caution is advised when using these substances.
