Why do you still have a cold and fever in hot summer?

In our daily life, the concept of a cold is caused by a cold, so it is particularly easy to catch a cold, have a fever and cough in autumn and winter. But catching a cold is not a patent in winter. Many people will catch a cold in summer and feel very uncomfortable, so many people will wonder why some people still catch a cold and have a fever in hot summer.

I ate too much cold food. It is very hot in summer, and many people can't stand the heat, so they like to drink cold drinks and eat ice cream, especially iced watermelons. Most people are greedy for cold, and they are also afraid of heat at night, blowing into air conditioners or fans. And it is very easy to sweat in summer. Many people will take a bath with cold water directly after sweating in summer. Although these methods can help the body to cool down temporarily, they are very unfavorable to the body. After the body is suddenly stimulated by these cold, it is very easy to cause vasoconstriction and cause a cold.

Second, protein content in human body is insufficient. Although the weather in summer is hot, it is sultry and humid, so many people will lose their appetite, often can't eat, and have no appetite, so most people will eat summer fruits or cold dishes. These foods are very nutritious, and there is no protein, so the human body will be deficient in protein. Without protein, the body's immunity will inevitably decline, so bacteria and viruses will enter at this time, causing patients to catch a cold.

Third, there is too little exercise. In summer, the weather is very hot. A little movement will make you sweat a lot, let alone exercise. Therefore, most people would rather stay in air-conditioned rooms and eat watermelons than go outdoors for the summer. Long-term inactivity can easily lead to the decline of body immune function. In addition, people who often stay in air-conditioned rooms have a closed environment and no ventilation, and there may be a lot of bacteria, viruses and other microorganisms in the air, which will increase the chance of catching a cold.
