Sleep late and get up early. In summer, the sunshine time is prolonged, the days are longer and the nights are shorter. At this time, it is necessary to adapt to the changes of yang excess and yin deficiency in nature, and also to "sleep late" and "get up early". It is recommended to go to bed before 10 at night and get up around 6 am. Master the principle of "meridian sleep", that is, sleep at noon and take a nap at noon. But the nap time should not be too long, generally half an hour is appropriate. Don't get up to work or study immediately after a nap, because there is insufficient blood supply to the brain at this time, and there will be temporary brain dysfunction, which will make people feel dizzy. It is best to lie still 10 minutes before getting up. Once Xia Hou's schedule is determined, he should be self-disciplined to protect his biological clock from disorder.

Diet: increase acid and reduce spicy. In summer, the liver qi of human viscera is getting weaker and the heart qi is getting stronger. You can eat some sour food in your diet, such as tomatoes, lemons, strawberries, grapes, pineapples and mangoes. To tonify the kidney, help the liver and regulate the stomach. Their sour taste can astringe sweat and dispel dampness, promote fluid production and quench thirst, and strengthen stomach and digestion. Try to eat less spicy food. Due to the spirit of the rising sun in summer, foods that are easy to get angry will cause fever inside and outside the body, resulting in acne, oral ulcers, constipation and other diseases.

Emotion: calm down and raise your spirit. In summer, the elderly are easily agitated, and in the long summer, they should "nourish their hearts" for health preservation. First, "quit dryness and anger", the elderly should try to keep quiet and feel comfortable. When the temperature is too high, it is best to go out less and avoid moderate and high-intensity exercise. Second, eat less high-fat and thick flavor in the diet, and eat more soy products, chicken and lean meat. It not only supplements nutrition, but also plays a role in strengthening the heart.

Health care: invigorating spleen and eliminating dampness. Summer is hot and humid, and the elderly are prone to spleen deficiency. It is suggested to eat red bean sparerib soup, red bean barley porridge and yam lotus seed soup once or twice a week, which can improve mental fatigue, loss of appetite, loose stool and other symptoms caused by spleen deficiency. In addition, don't overeat cold foods such as watermelon and bitter gourd, otherwise it will hurt the spleen and stomach and promote "internal dampness", which is not conducive to health. Old people should not stay in air-conditioned rooms for a long time, nor should they sit on wet stools and grass. After taking a shower, don't go to bed until your hair dries naturally or completely. Proper exercise and sweating are conducive to the discharge of moisture in the body, such as walking slowly, yoga, Tai Chi and so on.
