How to Use Cold & Heat Exposure to Improve Your Health

1. The Brain-Body Contract

The intricate relationship between the brain and body, often referred to as theBrain-Body Contract,” is a fundamental aspect of how cold and heat exposure can impact our health. This contract encompasses the communication system between the central nervous system (CNS) and various physiological processes throughout the body.
When exposed to extreme temperatures, this contract plays a pivotal role in regulating responses such as shivering or sweating to maintain thermal balance. One crucial component of the Brain-Body Contract in response to cold exposure is thermoregulation.
The hypothalamus, a region of the brain responsible for regulating body temperature, detects changes in external temperature through thermal receptors located on the skin. Upon sensing cold temperatures, the hypothalamus signals for vasoconstriction of blood vessels near the skin’s surface to conserve heat.
Additionally, it triggers muscle contractions that generate heat through shivering—a process where rapid muscle movements produce warmth as a means to raise core temperature back to homeostasis. In contrast, when exposed to heat,
