The apply of carrying a number of clothes beneath outerwear for heat throughout low temperatures is a elementary precept of thermal regulation. This system traps heat air generated by the physique between the layers of clothes, creating an insulating barrier in opposition to the chilly. For example, a base layer of thermal underwear can wick moisture away from the pores and skin, whereas a mid-layer of fleece offers insulation, and an outer shell protects in opposition to wind and precipitation.
Efficient thermoregulation is essential for sustaining core physique temperature in chilly environments and stopping cold-related sicknesses similar to hypothermia and frostbite. This layered method permits for adaptability to fluctuating temperatures; layers could be added or eliminated as wanted to take care of consolation and forestall overheating. The historic use of layered clothes for heat could be traced again centuries, evolving from easy animal hides and woven materials to the subtle technical supplies accessible at the moment.
