Description
Younger adults are less susceptible to hypothermia than the elderly, whose impaired ability to maintain core temperature during cold stress is widely documented. In a recently published study researchers have found that certain characteristics, which change with age, affect younger and older persons differently. The study examined the relative influence of ten physical characteristics thought potentially to play a role in how the body’s core temperature and tissue insulation react to cold. The characteristics they reviewed were age, sex, weight, body surface area, body surface area-to-mass ratio, sum of skin folds (an estimate of body fat), percent body fat, appendicular skeletal muscle mass (ASMM), and two thyroid hormone concentrations, T3 and T4.
