April 20th is the solar term in Grain Rain, followed by Grain Rain and Changxia. As the saying goes: "Chang Xia has a kind heart and is light without illness." Traditional Chinese medicine believes that the heart governs summer, the blood vessels, and the fire passes through the heart meridian. Summer is connected with the heart. Therefore, summer health should pay attention to maintaining mood.

In sports health care, you can choose walking, jogging, swimming and other sports, and the intensity of activities should be based on not feeling tired, so as to reduce the heart load. It is also advisable to replenish water in time after exercise, and drink light salt water if you sweat more. Adjust the pace of work and life in time, moderately slow down the pace, and be closer to nature. You can go for a walk and outing in the park, and you can also choose painting, calligraphy, chess, flower cultivation and other activities.

Hot weather and rising temperature can easily make people feel dry, and summer heat can easily hurt their spirits and lead to excessive heart fire, especially for middle-aged and elderly people. It is not uncommon for them to have unstable blood pressure and arrhythmia in summer due to weather changes or mood swings. Therefore, we should pay attention to mental and emotional recovery, keep a peaceful mind and a good mood, and relax as much as possible.

In summer, Yang Qi rises and falls, while Yin Qi weakens, which corresponds to the weakening of liver qi and the enhancement of heart qi. Diet is mainly light and digestible food, which can increase acidity and reduce bitterness, tonify kidney and help liver, and regulate stomach qi. You can eat more soy products, sesame seeds, walnuts, millet, bamboo shoots and so on. Drink more milk and eat less big fish and meat and spicy products such as onions and garlic. Excessive consumption of greasy and spicy foods can cause acne, sore throat, constipation and other diseases.

Attention should be paid to protecting gastrointestinal tract in summer. After summer, most people's appetite becomes worse, their digestive function is affected, and problems such as stomach pain, indigestion and acid reflux increase. Because of the hot weather, many people are greedy for raw and cold food, which is a bad stimulus to the gastrointestinal tract and easy to hurt the spleen and stomach yang. To prevent gastrointestinal diseases, we should pay attention to food hygiene, eat less cold drinks, supplement more fresh fruits and vegetables, eat three equal portions of rice, coix seed rice and red beans to eliminate moisture in the body.
