WebSep 1, 2015 · Thermoregulation is the maintenance of a relatively constant core body temperature. Humans normally maintain a body temperature at 37°C, and maintenance of this relatively high temperature is critical to human survival. WebHumidity affects thermoregulation by limiting sweat evaporation and thus heat loss. Humans cannot survive prolonged exposure to a wet-bulb temperature above 35 °C ... Age. Age can be a factor in a person's ability to adapt to temperature variations. Studies have shown that younger people adapt more efficiently to contact with cold surfaces ...

Estrogens generally promote vasodilation, heat dissipation, and lower body temperature and progesterone or progestins generally have the opposite effect.
WebMoreover, heat is transferred to the fetus via the placenta and the uterus, resulting in a 0.3 degrees C to 0.5 degrees C higher temperature than that of the mother. Therefore, fetal temperature is maternally dependent until birth. At birth, the neonate rapidly cools in response to the relatively cold extrauterine environment.
