In the hot summer days, the most common seasonal disease is heatstroke. Heatstroke is mainly caused by high temperature and poor ventilation in the environment, which makes the body heat unable to spread out in time. When going out at this time, you should adjust the time to avoid going out at high temperature at noon. Some old people often feel fidgety, fatigue, loss of appetite, and even dizziness, chest tightness, nausea and other symptoms in this season. Chinese medicine experts at Huakang Orthopedic Hospital said that it was "summer heat hurting qi", while folks said it was "bitter summer". In this regard, appropriate supplements can be made to ensure adequate sleep, and nap time can be used to make up for the lack of sleep at night. In diet, it is best to be vegetarian. Soybeans and bean products (such as tofu) are good for heart health. You can also eat more melon and watermelon, which is good for eliminating the evil of summer heat and dampness. There are folk sayings of "clear soup and white gourd" and "watermelon and green clothes". In order to eliminate or prevent the cold at night, we should take some ginger and drink more cold boiled water or mung bean soup every day, which can relieve summer heat and quench thirst.

The summer climate is hot, people are easily upset, tired and weak, so when self-care and exercise, we should be calm and ensure the vigorous heart function.
