Is it colder when the temperature is below zero in winter? Which is colder, minus 5 degrees or minus 16 degrees?

The higher the temperature below zero in winter, the colder it is. Negative 16 is colder than negative 5 and negative 16. According to the research of physiologists, around 30℃ is the best environmental temperature for human body, and it is also the temperature closest to human skin.

Sweat glands begin to develop at 33℃. After working at this temperature for 2-3 hours, the sweat glands, the "air conditioner" of the human body, began to start, and the accumulated body temperature was emitted through slight sweating.

The heat dissipation function of 35℃ can react immediately. At this time, the superficial vein dilates, the skin sweats, the heart beats faster, and the blood circulation accelerates. For some elderly and infirm people with poor heat dissipation, it is necessary to cooperate with local cooling or turn on indoor air conditioning to reduce human body temperature.

The first alarm was at 36℃. At this temperature, the human body "cools itself" by evaporating sweat and emitting heat. Sweat, sodium, vitamins and other minerals are discharged every day, and the blood volume is also decreasing. At this time, drinks containing salt, vitamins and minerals should be supplemented in time to prevent electrolyte disorder in the body, and other cooling measures should also be started.
