First of all, keep warm and cold. Warming the chest, head and feet in winter belongs to yin, so there is an old saying in winter that it is necessary to warm up after removing cold, which is very necessary to prevent cold attacks. In the cold, heavy snow and scorching sun, clothes should be increased or decreased according to the change of temperature. You should wear a hat, scarf and warm shoes, which is the best choice for winter protection. However, don't be too careful, that is, don't be too hot, don't be too thick, and be sure to choose the right one.
Secondly, drink plenty of water, moisturize and prevent dryness. It is easier to dry indoors after heavy snow. Although the amount of sweating and urination will decrease in winter, the cells in our brain and other organs still need water to moisten them. This can ensure the normal metabolism of the body. Therefore, in the cold winter, we should also drink more warm water and eat more fruits and fresh vegetables.
Keep the room ventilated and get into the habit of going to bed early. Indoor air pollution is many times more serious than outdoor air pollution in winter. Therefore, while keeping the indoor temperature normal, special attention should be paid to opening doors and windows frequently for ventilation. Fresh air will strengthen the brain and spirit. In winter, the days are short, the nights are relatively long and the sunshine is relatively weak, especially at night. Therefore, it is necessary to develop the habit of going to bed early, so as to achieve the effect of nourishing yang and insist on going to bed early. Don't stay up late and don't get up early.
