The observe of carrying a number of clothes beneath outerwear for heat throughout low temperatures is a basic 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 gives 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 diseases comparable to hypothermia and frostbite. This layered method permits for adaptability to fluctuating temperatures; layers might be added or eliminated as wanted to keep up consolation and forestall overheating. The historic use of layered clothes for heat might be traced again centuries, evolving from easy animal hides and woven materials to the subtle technical supplies obtainable immediately.
