Why do we tremble when cold?
Your body needs to maintain a constant temperature at 36.9 degrees Celsius. To avoid hypothermia and other consequences of coldness, your brain will keep a close eye on your body temperature.
If your skin surface is too cold, receptors on the skin send signals to the brain, from which the brain creates a series of movements to alert.
Shivering is one of those tricks. Then your muscles shrink and relax constantly. Besides trembling limbs, your jaw muscles also move, making your teeth collide with each other.
This convulsive exercise helps to generate heat, making your body temperature rise. It is also a warning sign that you need to find a place to heat and drink a glass of hot water.
