Humans possess complex thermoregulation. The body cools itself when heat is transferred from the blood to the skin, and the heat is then dissipated from skin to the environment, sometimes aided by sweat. The colder blood circulates throughout the body, lowering the body’s temperature. When the brain learns that the body is overheating, and the hypothalamus directs the body to speed up the process: more blood flows to blood vessels near the surface of the skin and sweat glands produce more sweat. As a result, more heat is removed from the body until homeostasis is achieved. 

 

The flexor side of the wrist is the best location to cool the body. The wrist features non-hairy skin, known as Glabrous skin, which possess specialized blood vessels that can release considerably more heat as compared to hairy skin. Glabrous skin is only found on the hands, feet, wrist, and ankles. But only the wrist is practical for a wearable, making it the optimal location to augment thermoregulation. 

 

Cooling Cuffs speed up this process and help you fight excessive heat. Concentrated cooling is applied to where the body can best dissipate heat, the wrist. The body returns to homeostasis quicker and sweat glands stop producing sweat sooner.

 

The result is an up to 66% faster cool down!
