1. In summer, many people gulp green tea to quench their thirst. Although green tea is unfermented, it retains more natural substances in fresh leaves, among which tea polyphenols and caffeine can retain more than 85% of fresh leaves. However, it is these natural ingredients that will have adverse effects on the human body if drunk on an empty stomach.

2, avoid cold food at night: people who are short in summer nights, slightly older, or slightly weaker, often have a cold abdomen, and their diet is not easy to digest, lettuce, melons and so on. This is a big taboo in summer, so you should pay special attention to eating this kind of food at night. Also be careful not to eat meat, noodles or anything cold and sticky at night, or you will see bloating, vomiting and diarrhea.

3, avoid cold water bathing: cold water bathing is the favorite way for many young and middle-aged men to cool off, but the summer weather is hot, and people's sweat holes and muscles are in a state of venting. Therefore, cold air can easily invade the human body, leading to the loss of yang. There are visible symptoms such as cold hands and feet, hamstring twitching, blurred vision in both eyes, and even unexplained fever syndrome. At the same time, even if you take a hot bath, you should pay attention to shelter from the wind after taking a bath, especially for children.

4. Eat only light vegetarian food: malnutrition

Because of the high temperature in summer, people like to eat light food, which can relieve the summer heat and prevent getting angry. But in summer, due to the high calorie consumption, it is more necessary to carry out comprehensive nutritional supplement. Heatstroke patients should mainly eat a light diet, but it is quite necessary to supplement it with fish, meat, eggs and milk. To ensure the necessary nutrition for the human body.

5, sleepy: easy to get yin and heat.

When enjoying the cool, don't be under the eaves or in the aisles, and stay away from the cracks in doors and windows to prevent thieves from invading and getting cold. It is best to exercise in the early morning or evening, and it is not advisable to do excessive and strenuous exercise. Sweating too much will not only hurt yin, but also hurt yang.

If the weather is too hot to sleep, you can open the window to ventilate after getting up in the morning and close the curtains before going to work. Turn on the air conditioner (about 27 degrees) after work at night, open the door of the room to ventilate each other, keep the room temperature difference balanced, and create a cool environment, which is naturally conducive to falling asleep.

6, nap can not be less: the summer days are long and the nights are short, the temperature is high, the human body has strong metabolism, and it is easy to get tired. Coupled with the hot weather, it often lacks sleep at night. So if possible, taking a nap for an hour or two in middle school will relax the brain and body system.

7, love to take a nap to check the cardiovascular system.

People often say that "spring is sleepy and autumn is lacking, and summer is a nap." In summer, the days are long and the nights are short. If people want to adapt to the changes of yin and yang deficiency in nature, they must go to bed late and get up early.

But in fact, because of the hot weather, people are not easy to fall asleep at night and wake up early in the morning, which is easy to cause insufficient sleep. Therefore, friends with conditions should gradually increase their lunch break, especially the elderly.

But be careful not to sit and take a nap, because your heart rate slows down and your blood flow slows down during sleep. Sitting and sleeping is easy to cause insufficient blood supply to the brain, and you will feel very tired after waking up. If the number of naps during the day is obviously increased, and the elderly are often sleepy, they often fall asleep unconsciously. They should be alert to the possibility of cerebrovascular diseases and go to the hospital for examination as soon as possible.
