While cooling rates may vary, the cooling rate for cold water immersion will be approximately 0.37°F/min. or about 1°F every three minutes when considering the entire immersion period for an exertional heat stroke patient.
Is hyponatremia considered heat related?
Hyponatremia was removed from the current guidelines as this condition is not considered to be a true heat-related illness. This will now be focused on in a new fluid replacement position statement, currently in development.
How to avoid heat related illness?
The best ways for athletes to avoid heat-related illness are to heat acclimatize before training hard or racing in a hot environment, monitor and manage your hydration needs, and utilize cooling techniques to help manage your core body temperature. Doing these three things well will reduce the physiological strain of training and racing in the heat and optimize performance.
How to get rid of heat illness?
This step is often missed, which allows heat illness to progress to dangerous levels. Get out of direct sunlight and into a shaded, cooler environment. Finally, use whatever you have to cool off.
How does heat acclimatization help?
The most important of these three is heat acclimatization because it not only improves thermal comfort, or your psychological tolerance to the heat, but also it improves your physiological thermal tolerance, which is your body’s ability to tolerate heat exposure for an extended period of time. The physiological benefits of heat acclimatization include increased skin blood flow and increased sweat rate, both of which help to dissipate heat quickly and efficiently. During heat acclimation you also have an increase in your blood plasma volume, which allows you to better sustain your blood pressure and work capacity (1). These adaptations take roughly 7-14 days to fully manifest. Because of this, it is important to monitor your level of exertion as your body makes these adaptations. During this time you will naturally have a change in threshold pace, power output, and both maximal and submaximal heart rate. Don’t force it.
How does heat illness develop?
Heat illnesses develop when you can’t adequately dissipate heat to the environment, and involves an incredibly complex relationship between your thermal physiology (all that heat you are producing), environmental heat strain, and your clothing (2). Many experienced endurance athletes are well versed in hydration and cooling strategies, ...
What are the two types of heat illness?
There are two main types of heat illness: classic and exertional. Classic heat illness is directly related to the environment and how the environment is effecting one’s ability to dissipate heat. These factors include high temperature and humidity, strong direct sun exposure, and still air. Exertional heat illness on the other hand is primarily ...
How does sweat affect body temperature?
The second way your body combats the likely rise in core body temperature is by increasing your sweat rate. This allows you to utilize evaporative cooling, which cools the body by creating a temperature gradient as sweat (or other water) evaporates from your skin surface into the air.
What is the normal temperature of the body?
Although 98.6 F (37 C) is generally accepted norm for human body temperature, it is normal for core temperature to fluctuate within a small range of 97-99 F (36.1-37.2 C). When your body increases much above or below this “set” temperature you can experience hyperthermia or hypothermia as your body tries valiantly to bring your body back to homeostasis. When you get too hot your one of the best way your body can cool itself down is to shift more blood flow to the capillaries that lie immediately underneath your skin. What this allows your body to offload some of the heat into the environment and in turn send cooled blood back deep into your body. The second way your body combats the likely rise in core body temperature is by increasing your sweat rate. This allows you to utilize evaporative cooling, which cools the body by creating a temperature gradient as sweat (or other water) evaporates from your skin surface into the air. The neat thing about the increase in your sweat rate per hour during the heat is that your sweat becomes more dilute than usual which makes it even easier for your sweat to evaporate from your skin into the air.
How is heat gained or lost from the body?
Heat is gained or lost from the body by one or more of the following mechanisms9,85: RadiationThe energy is transferred to or from an object or body via electromagnetic radiation from higher to lower energy surfaces.9,43,51,85,166.
How much water should an athlete drink after exercise?

Recognizing Heat Stroke
- Beyond Fluids. Heat stroke in football sometimes seems to hit with surprising speed. When this happens, a common theme of bewildered staff is, "But he got lots of fluids." The misconception is that hydration prevents heat stroke. The truth is that hydrating is critical but not sufficient to prevent heat stroke. Stress fluids but think "beyond fluids." All the factors described above can w…
Preventing Heat Stroke
- Cooler is Better. The cooler athletes stay, the better they play. In team sports, take frequent cooling breaks. Provide shade, ice water, and misting fans for rest breaks. As the temperature rises, reduce practice pace and duration and increase rest breaks. Have players sit in cold tubs after practice. Hold practices earlier and later, with more time between — time for rest, recovery, …
Treating Heat Stroke
- Medical Emergency. In heat stroke, every minute counts. When core temperature is very high, body and brain cells begin to die, so fast cooling is vital. Early features are subtle central nervous system (CNS) changes — altered cognition or behavior — and core temperature over 104-105 °F (40.0-40.6 °C). When an athlete collapses, the best gauge of core temperature is rectal temperat…
