1. Health preservation in summer is easy to be taboo.
First, don't be too cold where you sleep.
After people fall asleep, the activities of various parts of the body will slow down, the speed of blood circulation will also slow down, the body temperature will be lower than when they wake up, and the body's sensitivity to cold and heat is not as good as when they wake up. At the same time, the temperature is low at night, and it is easy to cause colds, enteritis and other diseases when sleeping. Take care of this and don't catch a cold.
Second, it is not advisable to wash with cold water when you are sweating all over.
After outdoor activities, people often like to take a cold bath to "cool down quickly" to eliminate sweat and heat as soon as possible. In this way, when the body suddenly washes cold water, the opened sweat pores will shrink immediately, so that the sweat pores will be closed, so that the heat can not be emitted and will stay in the body, causing high fever, rapid contraction of blood capillaries in the brain and insufficient blood supply, which will make people dizzy, and in the most serious case, it will also cause shock, reduce human resistance and catch a cold.
Third, the nap time should not be too long.
If the nap time is too long, the central nervous system of the brain will deepen the inhibition, prompting the capillaries of brain cells to close for too long, so that the cerebral blood flow will be relatively reduced. Sometimes the longer you sleep, the more tired you get, which is not conducive to entering the working state soon after waking up, and even makes you feel uncomfortable after waking up. Therefore, the nap time should not be too long, and it is appropriate to take about half an hour to an hour.
Fourth, it is not advisable to wear sunglasses that are too deep or too shallow.
Sunglasses can avoid the damage of ultraviolet rays to the eyes, but if the lens color is too dark, it will affect vision because of unclear vision; If the color of the lens is too much, ultraviolet rays can still damage vision through the lens. Therefore, summer sunglasses should choose green lenses that can transmit 5%~30% of light, which can not only resist ultraviolet rays, but also have the best visual clarity and the smallest color change when viewed through external objects.
Fifth, it is not advisable to wear a dark coat.
In the case of direct sunlight, it is best to wear light-colored clothes and sun hats, and underwear should be made of natural fibers with good sweat absorption such as pure cotton cloth. Dark clothes absorb heat, which is not conducive to human heat dissipation.
2. Matters needing attention in summer health care
1. Drink more water if you are short of water in summer.
Drink plenty of water, warm water is better. Drink seven or eight cups of boiled water every day. The body should keep and replenish water at any time. Water plays a vital role in the human body, maintaining the normal physiological functions of the human body. Water is an indispensable part of human body. Organs, muscles, blood, hair, bones and teeth all contain water, and water loss will be more in summer. If you don't replenish water in time, it will seriously affect your health, make your skin dry, increase wrinkles and accelerate human aging. In addition, mineral water, herbal tea, milk and apple juice are all ideal thirst-quenching drinks.
2. Live in time in summer
Go to bed late and get up early in summer, and try to take a nap at noon. Remember not to sit, lie down or sleep for a long time in the corridor, under the eaves or in the shade of the vents. Electric fans should not be used for a long time, because in summer, the outside is steaming at high temperature, sweating a lot, and the pores are wide open, which makes it easy to catch cold. If it is blown for a long time, it may cause headache, lumbar muscle strain, facial paralysis or muscle pain.
3. summer health should be "yang-nourishing"
"Huangdi Neijing Suwen Siqi Tiaoling" said: "Summer and March are called beautiful months, and everything is gorgeous. Go to bed at night and get up early, and never tire of it for a hundred days, which makes Chi angry, makes Huaying put on a show and vent his anger. If you love the outside, this summer's gas should be the way to keep fit. " In hot summer, many people will suffer from air conditioning disease. People turn on the air conditioner all day long, and the temperature difference between indoor and outdoor can reach more than ten degrees. In addition, a large number of cold drinks with ice will definitely hurt Yang. Therefore, we should pay attention to the living environment not to be too humid, not to eat too much frozen and cold food, not to adjust the air conditioning temperature too low at night, preferably above 26 degrees, and not to spend the night in the open air and cold places.
4, summer diet tonic

Bitter gourd: Take its immature fruit as a dish. The mature pulp can be eaten raw, cold, fried and grilled fish. It is fresh and refreshing and has a unique flavor.

8. Supplementing salt and potassium in summer
Sweating more in summer, and more potassium ions are lost with sweat, leading to hypokalemia, which will cause fatigue, dizziness, headache, loss of appetite and other symptoms. The most effective way to prevent potassium deficiency in hot weather is to eat more foods containing potassium. Fresh vegetables and fruits contain more potassium, so you can eat more strawberries, apricots, lychees, peaches and plums. Vegetables include green onions, celery, edamame, etc., and are also rich in potassium. Tea also contains more potassium. Drinking more tea in hot weather can relieve summer heat and supplement potassium, killing two birds with one stone.
9. Vitamin supplementation in summer
In summer, the human body sweats a lot, and sodium chloride loses a lot. Pay attention to supplementing salt while replenishing water. Drink some salty boiled water every day to keep the acid-base balance and osmotic pressure in the body relatively stable. Nutritionists also suggest that it is best to supplement vitamin B 1, vitamin B2 2 mg and calcium 1 g every day in high temperature season, which can reduce the consumption of sugar and tissue protein in the body and is beneficial to human health. Therefore, we should eat more foods rich in the above nutrients in summer, such as watermelon, cucumber, tomato, beans and their products, animal liver, shrimp skin and so on. You can also drink some juice.
10, try to wear light clothes.
Dark clothes will absorb sunlight and make people's body temperature rise and dry; At the same time, mosquitoes have the habit of blackening, and dark colors are easy to attract mosquitoes, especially black.
