The constant state of the internal environment is known as homeostasis. The processes the body goes through to achieve homeostasis are called homeostatic mechanisms. On a cold day, the decrease in body temperature is picked up by thermo receptors in the hypothalamus and peripheral thermo receptors in the brain. The hypothalamus is the modulator which stimulates different responses from the body to increase in heat production. These include; Shivering (minor contractions of muscles to generate heat), vasco constriction of the blood, decrease body temperature, pilo erection (hairs stand on end) and behavioral responses such as putting on warm clothes and staying under shelter. This process is known as a feedback system and its purpose is to gain homeostasis.

What is the different between wind chill and air temperature?

Wind chill is the perceived decrease in temperature caused by the effect of wind on exposed skin, while air temperature is the actual temperature of the surrounding air. Wind chill takes into account how wind speed affects heat loss from the body, whereas air temperature is a measure of the thermal energy in the air itself.


Why might it be a good idea to wear a jacket when the wind chill factor is up?

Wearing a jacket in windy conditions helps prevent heat loss from your body, keeping you warm and maintaining your body temperature. Wind chill can make the temperature feel much colder than it actually is, so a jacket provides an extra layer of insulation to protect you from the cold air.
