Why is it particularly easy to catch a cold in winter?

People may not notice that the weather is getting cold, or catch a cold before they react, and more seriously, they have a fever. So what is the reason for this phenomenon? Perhaps, from the following points, you will be inspired.

Because the temperature drops, the human body's ability to resist viruses also drops. If you don't keep warm, of course, it is easy to be invaded by viruses, leading to colds. Part of the important reason for this situation is that people still wear short sleeves in summer and autumn. After a series of autumn rains in summer, they caught a cold.

So we should do the following: First, pay attention to adequate nutrition. Picky food or frequent eating out can easily lead to nutritional imbalance and weaken the resistance to colds. Therefore, it is necessary to take a balanced intake of various yin and yang substances and drink plenty of water. Second, ensure adequate sleep. Sleep can regulate human immune function. Office workers sleep for not less than six hours, and students sleep for not less than eight hours. Third, keep personal hygiene. No matter what others do, you should pay attention to your personal hygiene. As the saying goes, disaster comes from the mouth and disease comes from the mouth. Only by taking care of your own hygiene can you be qualified to take care of others. Fourth, insist on washing hands frequently and go to crowded places less. Wash your hands frequently every day, because hand contact is the most susceptible to infection. When coughing or sneezing in public places, cover your nose and mouth with a handkerchief or paper towel to prevent droplets from splashing and infecting bacteria. Once you catch a cold, rest as much as possible and don't go to crowded public places to avoid cross-infection. Fifth, rinse your mouth with salt water. Rinsing your mouth with salt water after breakfast and dinner every day can remove oral germs. It is not enough to brush your teeth only twice a day. It is also very necessary to gargle at the right time. Sixth, keep exercising. Exercise can relieve stress, keep a happy mood, keep healthy and reduce the chance of catching a cold.

The above points are how to prevent colds when the weather turns cold. In other words, isn't it necessary to prevent colds if the weather is neither cold nor hot? In fact, we should always prevent colds all year round, regardless of spring, summer, autumn and winter, but autumn and winter are the high incidence seasons for colds.

The main reasons are: in autumn and winter, the weather turns cold, people stay in the classroom or at home because they are afraid of the cold, and the air circulation is not smooth, which naturally makes them easy to catch a cold; There is also human inertia. Because the weather is too cold, they don't like sports, lack the most basic physical exercise, and their physical fitness will decline, so it is a matter of time before they catch a cold.

In a word, when the weather gets cold, it's easy to catch a cold, so we should take precautions, for ourselves and for the health of others.
