You must "nourish your heart" in summer. Why?
Health preservation from summer solstice focuses on nourishing the heart, eating and exercising, just as Chinese medicine often says that summer is connected with the heart, and summer belongs to the fire and the heart. Summer heat disturbs the mind, and the phenomena such as sweating, fatigue, impetuous mood, palpitation and insomnia caused by summer heat are all related to the dysfunction of the heart, so it is very important to nourish the heart in summer.

During the summer solstice, you should choose to do physical exercise in the morning or evening when the weather is cool. You can choose places with fresh air, such as rivers, parks and beaches, and try to avoid strenuous exercise. During the summer solstice, you should exercise less or not. You can choose walking, jogging, Tai Ji Chuan, yoga, swimming and so on. And exercise without fatigue to avoid sweating a lot. Sweating too much not only hurts the vaginal fluid, but also hurts the yang.

Generally speaking, the human body should be balanced between yin and yang, and when the sun is strong in summer, it disturbs the yin and yang of the human body, and irritability and anger are unconsciously sprayed out. At this time, it is necessary to nourish the heart and soothe the nerves. Maintain a cheerful mood at ordinary times, pay attention to adjusting emotions, don't be sad and overjoyed, keep your mind stable and your heart is naturally calm. In fact, there are many ingredients or Chinese herbal medicines that can also help nourish the heart, and you can eat more in summer. For example, longan pulp can nourish the heart and soothe the nerves, lily can nourish yin and soothe the nerves, lotus seeds can transport the heart and kidney, poria cocos can induce diuresis and soothe the nerves, jujube can nourish the blood and soothe the nerves, and Zizyphus jujuba seed is the most important medicine to soothe the nerves.

"Nourishing the heart" not only conforms to the concept of keeping in good health in summer in the theory of traditional Chinese medicine, but also has very obvious practical significance because high temperature can easily make people nervous and fluctuate psychologically and emotionally in summer. In addition, high temperature reduces the immune function of the body, and patients are likely to have myocardial ischemia, arrhythmia and elevated blood pressure. Even healthy people may have emotional irritability. Therefore, nourishing the heart is also a good way to prevent emotional ups and downs and even prevent diseases.

Modern medicine has also found that when the temperature exceeds 33℃, human metabolism will be significantly improved, thus increasing the workload of the heart. At the same time, when the weather is hot, sweat glands open to dissipate heat, sweat too much, blood volume decreases and viscosity increases, making it more difficult for the heart to pump blood. In summer, the heart is very tired, and its own nutrition supply is poor, so it is easy to have problems if you are not careful. Therefore, keeping in good health in summer focuses on nourishing the heart.

Comfortable living environment Too hot environment will affect the quality of sleep. Remember to air the room in the morning. And clean the room regularly to ensure a clean and refreshing sleeping environment.

Don't be greedy when sleeping at night. You can cover a quilt in summer, which is lighter and more breathable, warmer than a small blanket, less likely to catch cold and sleep more comfortably. Especially middle-aged and elderly people, we should pay more attention to sleep health.

Don't stay up late. Staying up late often will overload the heart and lead to long-term discomfort, which often leads to acute heart disease. Many reasons for sudden death after staying up late are myocardial infarction, which has become one of the super health killers. We must be absolutely vigilant.
