In spring, the air in nature is always rising, and the indoor temperature is often higher than the outdoor temperature, so in this case, everyone will pick up clothes to cool down, but it is wrong for the elderly to say so, and then the elderly will stop this practice and say that we have to take off our clothes in a hurry, which will make us sick.
Second,? From winter to spring, it changes from cold air to hot air. Although the weather is getting warmer in this transitional period, the climate is constantly changing. It will become very cold for a while and very hot for a while. When the sun comes out, it is usually very hot. If the sun goes down, it will feel particularly cold. People wear a lot of clothes in winter. If they take off too much in spring, they can't adapt to this climate, so they catch a cold easily.
Third,? Autumn and winter are the stages of temperature drop. The indoor temperature lags behind the outdoor temperature due to the heat of the house, so there is an opposite temperature difference. Therefore, it is particularly warm indoors and cold outdoors, so we need to put on more clothes. In fact, we all know that from summer to spring is a stage from hot to cold. Although the weather is particularly cold, it takes a process to change. Some people put on a lot of clothes soon in autumn, and then put them off until noon.
Therefore, all of us must listen to the old man. They are particularly experienced in dress. They know when to add clothes and when to cut them, so that we won't get sick, including other things, and we don't want the old people to be wordy, because everything they say is based on experience.
