many people don’t like summer because the hot weather in summer is difficult to bear. High temperature and heat make many people want to find a cool place, so they will hide in the air-conditioned room and eat cold drinks… It is such extreme behavior that often poses hidden dangers to their health. Summer is also exquisite, can not be taken lightly. The following small series will teach you 10 unsuitable ways to relieve summer heat in summer:

should not eat more cold food

in hot summer, if the gastrointestinal tract is stimulated by a large number of cold food, it will accelerate peristalsis, shorten the residence time of food in the small intestine and affect the human body’s absorption of food nutrition.

at the same time, due to the high temperature in summer, the heat in the body is not easy to dissipate, and the temperature in the gastrointestinal tract is also high. If suddenly stimulated by cold, it can lead to gastrointestinal spasm and abdominal pain.

should not sit on wood

as the saying goes: “don’t sit on stone in winter, don’t sit on wood in summer”. In summer, the temperature is high and the humidity is high. Wood, especially the wood, chairs and stools that have been placed in the open air for a long time, is exposed to the rain and contains more water. When the sun is exposed, the temperature rises, it will emit damp heat, making people vulnerable to skin diseases, rheumatism and arthritis.

should not sleep in the open at night

in midsummer, the sweat glands on the body constantly secrete sweat to radiate heat from the body. After falling asleep, the body is in a relaxed state and the resistance decreases temporarily.

at this time, if it is night, the temperature drops, the cold wind strikes again, and dew is added to the body, it is easy to cause headache, abdominal pain, joint discomfort, indigestion and diarrhea. Sleeping in the open at night is also easy to be bitten by mosquitoes and may be infected with diseases, such as cerebritis.

should not lack 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 easy to fatigue. Coupled with the hot night, sleep instability, resulting in lack of sleep. Therefore, sleeping for an hour or two at noon is of great benefit to health. It can rest all systems of the body and is also a good measure to prevent heatstroke.

electric fan should not be blown too long

electric fan blowing too long will destroy the equilibrium state of sweating, make people feel headache, dizziness, sore legs, soft hands and general discomfort. In severe cases, it may also induce other diseases. It’s easier to catch cold when you sleep with your fan on on a midsummer night. Especially the elderly and children should pay more attention.

air conditioner should not be turned too large

air conditioner can bring a comfortable environment to people. However, if the indoor and outdoor temperature difference 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” and “catch a cold”. Moreover, if the indoor and outdoor temperature difference is too large and do not pay attention to indoor ventilation, the indoor air will be turbid, resulting in the breeding of various pathogenic microorganisms.

if people’s body resistance decreases, they are prone to disease. Therefore, the temperature difference of air conditioner in summer is not easy to be too large, preferably between 5-8 degrees and no more than 10 degrees.

is not suitable for “rapid cooling”.

in hot summer, people often like to take a cold bath to “rapid cooling” in order to eliminate sweat and heat as soon as they go out. However, because people absorb a lot of heat in the sun, the pores of the whole body close quickly, so that the heat cannot be emitted and remains in the body, causing high heat.

also causes insufficient blood supply due to the rapid contraction of brain capillaries, making people dizzy, and severe cases can also cause shock; And at this time, the resistance of the human body decreases, and the cold will “enjoy the cool”. Therefore, the best way is to dry the sweat on your body or rinse it after the sweat is dry.

is extremely thirsty.

people sweat a lot in summer. If someone drinks a lot of water at once, it will increase the burden on the heart, reduce the blood concentration, and even panic, shortness of breath, sweating and other phenomena. If they are extremely thirsty, they should drink a small amount of water first and stop for a while.

do not 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 the vision due to unclear vision; If the lens is too light, it can still damage the eyes.

therefore, the selection of sunglasses in summer should allow 15% – 30% of the visible light to pass through the gray or green lens, which can not only resist ultraviolet rays, but also have the best visual clarity and the smallest color change of external objects.

beverages should not be used to replace boiled water

soda, fruit juice, cola and other beverages contain more saccharin and electrolyte. These substances will cause adverse stimulation to the stomach and affect digestion and appetite. If they are drunk in large quantities, they will also increase the burden of renal filtration and affect renal function.

and excessive intake of sugar will increase human calories and make people obese. Therefore, it is not suitable to drink more drinks in summer. It is better to drink boiled water, especially for children and the elderly.
