In order to spend the hot summer healthily and safely, people must follow three principles and eight points for attention in summer health preservation.

(1) Three principles:

Pay attention to your daily life. In summer, we should insist on "going to bed late, getting up early and taking a lunch break". In summer, the sun rises early, the air is fresh, and outdoor activities after getting up are conducive to fitness; The temperature is high at noon, so a proper nap can supplement the lack of sleep at night. Indoor ventilation and watering should be carried out frequently, and the temperature can also be adjusted with the help of desk fans, ceiling fans and air conditioners, so that the indoor temperature can be kept at around 25℃, with the maximum not exceeding 30℃ and the humidity at around 60%. Fluorescent lamps should be used indoors, not incandescent lamps. Windows should be hung with light green or light blue curtains to increase the cool and quiet feeling. It is determined that the temperature of the wall covered by trees can be about 8℃ lower, and the temperature of the balcony with vines can be about 5℃ lower. Therefore, if the house is well afforested, its interior will be fresh and cool. In summer, people are vulnerable to wind, cold and humidity, so don't sleep on the ground or balcony in summer, facing the fan or window.

Adjust your diet. Summer diet should be light, fresh and easy to digest, such as fruits and vegetables, eggs and bean products. Eat less fatty and spicy things that get angry. Pay attention to color, smell and taste in cooking to increase appetite. Drink more boiled water or mineral water containing trace elements; You can also make some cool food yourself, such as mung bean porridge, lotus seed porridge, lotus leaf porridge, red bean cake, sour plum soup, chrysanthemum tea and so on. You can also eat some fresh cold salad, and add some seasonings such as vinegar, garlic paste and Jiang Mo, which can not only relieve summer heat and dampness, strengthen the spleen and benefit the kidney, but also inhibit bacteria and prevent intestinal diseases.

A study shows that 10% people will have emotional, emotional and behavioral abnormalities in summer, showing emotional disorders. The ancients said, "Breathing meditation is like trillion snow in your heart." Therefore, people in Xia Hou should first have a calm mind, a steady mind and a happy mood. They should not be excited by heat and impatience, but should be "calm and naturally calm". Talk as little as possible in hot weather, do not do strenuous physical activities and nervous mental thinking, and do not work and walk for a long time in the scorching sun. "The Medical Book" points out: "People who take good care of their lives are not bothered or bitter, and the shape of God is safe. What makes patients?"

(2) Eight points for attention:

Adequate sleep and health come from sleep. As the saying goes, "sleep well every day and you will never get old." Good sleep can enhance the body's ability to resist aging and prevent diseases. Because of the harassment of mosquitoes and flies in summer, the weather is hot and uncomfortable, and people often lack sleep or sleep badly. Therefore, ensuring adequate sleep is an important part of summer health care. First of all, take a nap 1 ~ 2 hours every day; Secondly, people should not sleep too late, so as not to disturb the biological clock rhythm; Third, we should strive to create a comfortable, quiet, harmonious and completely relaxed sleeping environment.

Don't eat too many cold drinks. Eating too many cold drinks will stimulate gastrointestinal peristalsis, shorten the residence time of food in the gastrointestinal tract, and affect the body's absorption of food nutrition. In addition, human body heat is difficult to dissipate in hot summer, and the gastrointestinal temperature in the body is high. Suddenly eating a lot of cold drinks can lead to gastrointestinal colic and abdominal pain.

Old people who don't sit on the wood for a long time often say, "Don't sit on the stone in winter and don't sit on the wood in summer." The reason is that the temperature is high and the humidity is high in summer, and the wood (such as chairs and stools) placed in the open air for a long time contains more water. On the surface, it is dry. After exposure to the sun, it will emit moisture, and sitting on it for a long time will induce hemorrhoids and arthritis.

Go out for sun protection, and try to avoid the "scorching sun" at noon when going out in summer. When you really need to go out, you should wear an umbrella or a sun hat, sunglasses, etc. If possible, you can apply sunscreen to the exposed parts. When working in the hot sun, you should have regular rest.

The diet is rich in potassium and sodium. In midsummer, people sweat a lot, which often consumes body fluids, resulting in more loss of potassium and sodium. Therefore, it is advisable to supplement more water and potassium and sodium elements, such as eating more fruits and foods containing sodium to prevent hypokalemia and hyponatremia.

Don't be greedy at high temperatures. When you come back from going out, don't wash your sweaty body with cold water immediately, so as not to suddenly close your pores and leave heat in your body. Don't lie on the brick floor or terrazzo floor to prevent arthritis and sciatica. Don't adjust the air conditioning temperature too low, so that the temperature difference between indoor and outdoor is too large, which makes it difficult for the human body to adapt when going in and out; Don't let the fan blow directly on your body for a long time, so as to avoid the imbalance of human regulation and cause diseases.

Tonic supplements should benefit qi and high fever in summer, and the human body sweats a lot, which often leads to qi deficiency and body fluid discharge. Chinese medicine has a method of invigorating qi and preventing heatstroke, that is, when taking supplements in summer, it is advisable to choose some drugs for invigorating qi and take them several times in order to strengthen the body resistance. The most commonly used tonic in summer is American ginseng, or 3 grams of Schisandra chinensis is mashed and decocted instead of tea, which can cure qi deficiency, thirst and hyperhidrosis.

Early prevention of diseases In summer, the temperature is high, mosquitoes, flies, insects and pathogenic microorganisms multiply quickly, and the human body consumes a lot at this time, and its resistance is reduced, making it easier to get sick. It's too late to "cure diseases and save lives", and prevention is the most important thing in summer. First of all, we must prevent and treat cardiovascular and cerebrovascular diseases. According to the data, after entering May, the hospitalization rate of stroke and coronary heart disease increased, and the mortality rate increased significantly. The main reason is that there is more water loss in the body, which leads to blood concentration and increases the probability of thrombosis, embolism and arteriosclerosis plaque formation; Coupled with fatigue, emotional instability, biological clock disorder, neuroendocrine dysfunction and so on. , leading to hypertension, ischemia and hypoxia of heart and brain cells, leading to the occurrence, development and recurrence of cardiovascular and cerebrovascular diseases.

Second, prevention and treatment of gastrointestinal diseases. Acute gastroenteritis, vomiting, diarrhea, abdominal pain, etc. It often happens because gastric acid is diluted by a lot of drinking water, and its ability to kill germs is weakened.

Third, prevent and treat colds. Summer colds are often accompanied by summer dampness, with symptoms such as fever, headache, stuffy nose and runny nose, sore throat, cough with yellow phlegm and dry mouth. Most of them are caused by excessive temperature difference between air-conditioned rooms, sleeping with a fan, catching cold in the rain, sweating, and cold water washing, and can also be caused by the loss of vitality such as summer fatigue and wind-heat evil.

Fourth, prevent skin diseases. Such as mosquito bites, prickly heat, boils, sleeping pad allergies, etc., these skin diseases are often scratched by hands due to itching, leading to infection and pain. In addition, there are air-conditioning diseases, heatstroke, summer mood disorders, sub-health "bitter summer" symptoms. Should be prevented as soon as possible and treated in time.
