What is Heat Shock?
Have you ever been stuck outside on a really hot day and started feeling terrible? Or maybe you’ve had the flu with a fever that kept creeping up, and it made you feel lousy? This is your body reacting to heat shock.
Heat shock occurs when your cells are warmed past their optimal temperature (with humans that is approximately 98.6 deg F). A cell usually ‘knows’ its optimal temperature as the temperature it was developed at. When they are feeling stressed, cells send out an ‘SOS,’ calling in the help of heat stress proteins and activating the stress response.
The Heat Shock Response
All cells have a temperature range that encompasses their ‘happy place.’ They function properly in this range, but things go badly when they get too hot or too cold. When cells undergo stress due to changes in temperature, they begin to break down, and one specific side effect is an abundance of proteins that remained unfolded (under-developed). A protein’s function is determined by its shape, and when unfolded proteins are near each other, they can begin to stick together, causing problems in the body.
