Vasodilation is when your blood vessels widen (dilate) after they’ve been narrowed (vasoconstriction) in response to the cold. This physiological process is also known as cold-induced vasodilation (CIVD) and it’s there to help you keep a steady temperature. CIVD also protects your extremities, such as fingers, toes, nose, and ears, from frostbite and other cold-related…
The Lewis Phenomenon, more commonly called the Hunting Response, is an example of the body’s natural responses to the cold. This natural process helps regulate body temperature and protect against frostbite. As part of the body’s survival mechanisms, the Lewis Phenomenon offers insights into how humans adapt to extreme environments while maintaining critical physiological functions….
Our bodies have a fascinating set of mechanisms designed for survival in different environments. One of these mechanisms is called the “hunting response” or the “Lewis hunting reaction”. This is a thermal response that our bodies use to adapt to cold temperatures, but it actually has very little to do with actual hunting. The hunting…
