When the season changes, many people catch a cold. What is the reason?

As soon as the season changes, many people catch a cold: changing seasons is a period of alternating cold and heat, epidemic infectious diseases and changeable emotions. Overwork, sedentary driving, drinking and smoking can all easily lead to colds.

Preventive measures for seasonal colds;

1, don't add or subtract clothes suddenly.

Seasonal changes, the biggest feature is the change of temperature, and the body needs a smooth adjustment process. For example, from winter to spring is a process from cold to warm.

Be careful not to cut clothes suddenly this season. Although the temperature is very warm and it feels very hot, you can't wear short-sleeved skirts. You can change them slowly. Brush your teeth in the morning, wash your face with cold water and wear thinner clothes. The gradual transition after 7 days can prevent the self-cause caused by a cold.

2. A reasonable diet.

Diet should be light, avoid greasy, spicy and cold; Eat more fresh vegetables and fruits to keep the stool unobstructed; Cooking mung bean porridge, lotus seed porridge, lotus leaf porridge and jujube porridge at home can prevent heatstroke and cool down; Drink plenty of water; Eat less high-sugar and high-salt foods; Eat less fried food; Quit smoking and limit alcohol. Animal liver is the first choice to prevent colds.

Because the liver contains a variety of vitamins, especially vitamin A and vitamin B 12, these vitamins can enhance the body's resistance.

3. Combination of work and leisure.

Chinese medicine believes that staying up late is easy to hurt people, so it is very important to ensure adequate sleep in summer nights. You should also have enough exercise. If you stay at home and watch TV all day, or you are too busy, work long hours and get tired easily, it will lead to the decline of human immune function and the occurrence of colds.

4. Keep a good attitude.

People who are often worried may lead to low immune function and weakened ability to swallow pathogenic microorganisms, giving the invading respiratory virus an opportunity.

It is reported that the number of people who are often worried about respiratory virus infection is 3-5 times that of the control group, and the resistance of people with great psychological pressure and introverted personality to cold virus is obviously reduced. Therefore, a cheerful and optimistic mood is an effective way to prevent colds.
