The climate is changeable in March and April every year. It was very hot yesterday, but it suddenly turned cold today. Or it's cold in the morning and evening, and it feels hot at noon. Or it was sunny yesterday and cloudless in Wan Li, but it's windy and rainy today. It is this erratic and unpredictable climate change that easily reduces people's resistance and leads to colds. So what should be done to prevent colds?
Dress appropriately and keep warm.
The weather is hot and cold, cold in the morning and evening, hot during the day, and everyone will be upset because they don't know what to wear. Everyone just needs to pay attention to adding clothes when the weather is cold, going out to wear a coat in the morning and evening, sweating a lot during exercise, and not taking off a lot of clothes suddenly, which is easy to cause a cold alternately.
