Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
The average difference between oral and axillary temperatures of Indian children aged 6–12 was found to be only 0.1 °C (standard deviation 0.2 °C), [51] and the mean difference in Maltese children aged 4–14 between oral and axillary temperature was 0.56 °C, while the mean difference between rectal and axillary temperature for children ...

With humid heat, the moisture in the air can prevent the evaporation of sweat. [21] Regardless of acclimatization, humid heat poses a far greater threat than dry heat; humans cannot carry out physical outdoor activities at any temperature above 32 °C (90 °F) when the ambient humidity is greater than 95%.
Cotton is one of the most breathable materials, so cotton sheets or blankets could help keep you cool through the night. Shutterstock The lower the thread count of the cotton, the more breathable ...

In shivering, the heat is the main intended product and is utilized for warmth. [citation needed] Newborn babies, infants, and young children experience a greater (net) heat loss than adults because of greater surface-area-to-volume ratio. As they cannot shiver to maintain body heat, [citation needed] they rely on non-shivering thermogenesis.
Alcohol consumption increases the risk of hypothermia in two ways: vasodilation and temperature controlling systems in the brain. [30] [33] [34] Vasodilation increases blood flow to the skin, resulting in heat being lost to the environment. [33] This produces the effect of feeling warm, when one is actually losing heat. [34]
