The weather is hot, the days are long and the nights short, and the climate is dry. Chinese medicine believes that summer belongs to fire in the five elements, and the corresponding viscera is "heart". Therefore, Director Zhao said that the key to keeping in good health in summer is to raise the "heart", but the "heart" mentioned by Chinese medicine does not just refer to the "heart", but the whole nervous system including the heart, and even mental and psychological factors.

It's very hot in summer, so people are easily agitated. Therefore, mental health care can not be ignored. Maintaining a peaceful mind and a happy mood is conducive to reducing the excitability of sympathetic nerves, slowing down metabolism and relieving the feeling of dryness and heat. When you are depressed and upset, you might as well listen to soothing music and look at beautiful picture books. Indoor curtains and decorations should also be light-colored, so as to keep a good mood.

Adequate sleep is conducive to peace of mind. Therefore, in summer, we should stay up late and get up early to adapt to the changes of yang excess and yin deficiency in nature. At the same time, taking a nap to supplement the lack of sleep can also effectively prevent heart diseases such as coronary heart disease and myocardial infarction. Generally, a nap should start at 15-30 minutes after lunch. Because sitting and lying is not conducive to eliminating fatigue, it is appropriate to take a nap in prone position. The nap time should not be too long, and it is appropriate to 1 hour to 1.5 hours. Alcohol, coffee and strong tea should not be drunk before going to bed.
