Why do people tremble when they are very cold?

It's hot recently, and I simply don't know how to live without air conditioning, a life-saving artifact. A few days ago, the air conditioning temperature was a little low, and my daughter was shivering with cold.

But the little guy's first reaction was not to ask me to turn up the temperature of the air conditioner, but to ask me why people tremble when they are cold. I have to answer her questions patiently.

1. Why do people tremble when they are cold?

1, I told my daughter that shivering is actually a function of the human internal environment control system. Tremor is a way for the hypothalamus to keep the body warm. When the body gets cold, trembling can release energy.

2. Hypothalamus is located at the back of the eye, and there is a tiny brain tissue responsible for controlling body temperature. Sweating is also controlled in this part.

Second, the baby sometimes shivers all over, or his chin and limbs tremble.

1. It is normal that the baby has a "tingling sensation" all over his body and his hands and chin tremble briefly. This is because the baby's nervous system is immature. This situation will gradually disappear as the baby grows up.

The baby is separated from the mother's body when the brain is immature. After birth, the baby's brain needs to continue to develop.

Because the baby's nervous system is underdeveloped, the central nerve cells are highly excited, which is easy to cause excitement after being stimulated, and the baby's nerves are still immature in controlling muscle movements, so there are often involuntary shaking of hands and feet.

3, especially when stimulated by strong light, sound or vibration, but these jitters will gradually disappear with the development of nerves. As long as the shaking action is not big and lasts for a long time, we can give the baby a sense of security by comforting the arm or wrapping it in swaddling clothes, so as to stop shaking.

However, if the baby's hands and feet are shaking for a long time, the comfort is ineffective, and the baby has crying and pain, it is necessary to take the child to the hospital for a systematic examination.
