What happens when you feel very cold, your hair gets erect. Standing hair is also known as Goosebumps. This is the most common reaction that occurs when the body gets cold or due to a sudden change in the emotional response. Actually, when for some reason small skin gets raised in our skin, due to which the hair and hair on the body are standing upright, then this phenomenon is called Goosebumps.

It is worth noting that due to the shrinkage and contraction of the small muscles attached to each hair on the skin, the hair grows erect. Each shrink muscle creates a shallow hole on the surface of the skin from which the surrounding part emerges. When a person feels cold, something feels the same. The same thing happens in animals. Their thick and thick hair gets spread when they stand and hide a small amount of air which acts as an insulation layer. The thicker the layer of hair, the more heat it will prevent.

Also note that behind this, the stress hormones, called adrenaline, stand up only when they are released in the subconscious state. The release of this hormone not only causes contraction and contraction in the skin muscles but also affects other functions of the body. In animals, this stress hormone is released when they feel cold or when they are under some kind of stress or stressful situation.
