Matters needing attention in summer health care

1, not suitable for sleeping at night.

In midsummer, sweat glands on the body constantly secrete sweat to radiate heat in the body. After falling asleep, the body is in a relaxed state, and the resistance temporarily drops. At this time, if it is night, the temperature drops and the cold wind strikes again, the body will replenish dew, which will easily lead to headache, abdominal pain, joint discomfort, indigestion and diarrhea. Sleeping at night is also easy to be bitten by mosquitoes and may be infected with diseases, such as encephalitis.

2. It is not advisable to take a nap.

In summer, the days are long and the nights are short, the temperature is high, people's metabolism is vigorous, the consumption is also large, and they are prone to fatigue. Coupled with the hot night, sleep instability, resulting in insufficient sleep. Therefore, taking a nap for an hour or two at noon is good for your health. It can rest various systems of the body and is also a good measure to prevent heatstroke.

3, should not eat more cold food.

In hot summer, if the gastrointestinal tract is stimulated by a large number of cold foods, it will accelerate peristalsis, shorten the residence time of food in the small intestine, and affect the absorption of food nutrition by the human body. At the same time, due to the high temperature in summer, the heat in the body is not easy to dissipate, and the temperature of the gastrointestinal tract is also high. If you are suddenly stimulated by cold, it will lead to gastrointestinal spasm and abdominal pain.

4, thirst is extremely unsuitable for drinking.

Sweating a lot in summer, some people drink a lot of water at once, which will increase the burden on the heart, reduce the blood concentration, and even cause palpitation, shortness of breath and sweating. If you are very thirsty, you should drink a small amount of water first and then drink it later.

5, it is not appropriate to use drinks instead of boiling water.

Soft drinks, fruit juice, cola and other drinks contain more saccharin and electrolyte. These substances will cause bad stimulation to the stomach, affect digestion and appetite, and if ingested in large quantities, it will also increase the burden of renal filtration and affect renal function. Moreover, excessive intake of sugar will increase human calories and make people obese. Therefore, it is not advisable to drink more drinks in summer. It is best to drink boiled water, especially for children and the elderly. Drink less drinks and drink more water.

6. Don't blow the electric fan for too long.

Blowing the electric fan for too long will destroy the balance of sweating, make people feel headache, dizziness, leg pain, general discomfort, and even induce other diseases in severe cases. It is easier to catch a cold when sleeping with an electric fan on midsummer night. Especially the elderly and children should pay more attention.

7. Don't turn on the air conditioner too much.

Air conditioning can bring people a comfortable environment. However, if the temperature difference between indoor and outdoor is too large, it is difficult for people to adapt to the indoor and outdoor temperature changes and it is easy to "catch a cold". Moreover, if the temperature difference between indoor and outdoor is too large and indoor ventilation is not paid attention to, the indoor air will be turbid, leading to the breeding of various pathogenic microorganisms. If a person's body resistance is reduced, it is easy to get sick. Therefore, the temperature difference between air conditioners in summer is not easy to be too large, preferably between 5-8 degrees, and the maximum cannot exceed 10 degrees.

8. Don't 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 light, ultraviolet rays can still harm the eyes through the lens. Therefore, when choosing sunglasses in summer, 15%-30% of visible light should be allowed to pass through gray or green lenses, which can not only resist ultraviolet rays, but also have the best visual clarity and the smallest color change when viewed through external objects.

9. It is not advisable to sit on a log.

As the saying goes, "Don't sit on a stone in winter and a tree in summer." The temperature is high and the humidity is high in summer. Wood, especially wood, chairs and stools placed in the open air for a long time, is exposed to rain and contains more water. When the sun shines and the temperature rises, it will emit damp heat, which makes people susceptible to skin diseases, rheumatism and arthritis.

10, not suitable for "quick cooling"

In hot summer, people often like to take a cold bath to "cool down quickly" in order to sweat and dissipate heat as soon as possible. However, because people absorb a lot of heat in the sun, "rapid cooling" makes the pores of the whole body close quickly, so that the heat cannot be distributed and stays in the body, causing high fever, and it will also cause insufficient blood supply due to the rapid contraction of brain capillaries, which will make people dizzy and even cause shock. At this time, the human body's resistance is reduced, and the cold will "enjoy the cold." So the best way is to dry the sweat on your body first, or wash it after the sweat dissipates.
