Why do you tremble when you are cold?

Tremor is a function of human internal environment control system. There is a tiny brain tissue behind the eyes, called hypothalamus, which is responsible for controlling body temperature. Tremor is a way for the hypothalamus to keep the body warm. When the body gets cold, trembling can make the body release energy (on the contrary, when the body gets hot, trembling can make people sweat).

Matters needing attention in cold weather:

1, don't go on a diet

After "autumn clothes", the weight will inevitably rise, and some people have started the idea of dieting to lose weight. They think that if you don't sweat in winter, you have less exercise, and your body needs less calories, you can lose weight by eating less. But this will lead to decreased resistance.

2. Don't eat too spicy.

Many people will choose spicy hot pot to "warm up". Spicy food not only stimulates taste buds, but also stimulates gastrointestinal tract, causing pain and fever, making people feel warm from the inside out.

However, this kind of stimulation is a challenge to the digestive tract, especially for sensitive and easily inflamed people. After eating spicy food, their blood vessels dilate, their faces turn red, their pores open and they sweat profusely, and the accumulated heat in their bodies is emitted into the air with sweat. If they suddenly go from indoor to outdoor, their pores will not be closed enough and they will easily catch a cold.
