1, 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.
2. Take a cold bath? Cooling? This is a misunderstanding.
Many people think that using cold water? Shower? It makes people more comfortable and can cool down. But in fact, use cold water when sweating? Shower? It will make the pores of the whole body close quickly, so that the heat in the body cannot be distributed and stays in the body, which is easy to cause various diseases.
The correct way is to choose warm water bath, because warm water bath dissipates heat faster, and it will make people feel refreshed after bathing.
3, electric fans, air conditioners and other refrigeration tools should not be blown for a long time.
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.
Many people think that in hot weather, the lower the indoor air conditioner is, the more comfortable it is. But in fact, if the air conditioner is turned on too low, the temperature difference between indoor and outdoor will be too large, which is easy to get heatstroke.
It is unscientific to pour water in a sealed room to cool down.
Many people like to splash water indoors to cool down. In fact, the method of splashing water does make water vapor evaporate and take away some heat. So just after pouring water, the indoor temperature will drop temporarily. However, if the indoor ventilation is not good, the air is not circulating, and the water splashes on the ground, it is difficult for the evaporated water vapor to be distributed to the outside and stay in the air, which will increase the humidity of the indoor air and increase the indoor temperature after a long time. At this time, people will feel bored indoors, which will lead to heatstroke.
In addition, due to the high temperature in summer and the rapid evaporation of water, indoor bacteria and dust enter the air with water vapor, making the air more turbid than before splashing water.
5, keep the necessary 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.
6, remember not to drink instead of boiled water.
Frozen drinks such as soda, juice and cola have become popular drinks in summer. These drinks contain more saccharin and electrolyte, which will cause bad stimulation to the stomach and affect digestion and appetite. If you drink a lot, it will also increase the burden of kidney filtration and affect renal function. Moreover, excessive intake of sugar will increase human calories and make people obese.
7, thirst should not be urgent to drink
Sweating a lot in summer, drinking a lot of water at once will increase the burden on the heart, reduce the blood concentration, and even cause palpitation, shortness of breath, sweating and other phenomena. In summer, you can't wait until you are thirsty to replenish water. If you are extremely thirsty, you should drink a small amount of water first and then drink it later.
8. Pay attention to proper diet.
Eat less spicy and fried foods, eat more fruits and vegetables, and drink more water or heat-clearing drinks such as green tea and Sangju granules to ensure enough effective circulation, so as to achieve the purpose of promoting blood circulation, removing blood stasis, clearing fire and expelling toxins.
9. After heatstroke, you should drink light salt water or fresh fruit juice instead of plenty of boiled water.
Many people drink a lot of boiled water after heatstroke. Although drinking boiled water during heatstroke can replenish water, can drinking too much boiled water produce when people are dehydrated? Out? Reaction, the result returned to the state of dehydration. The correct way is to drink some light salt water or fresh fruit juice.
10, drink more mung bean soup and herbal tea with caution.
For heatstroke prevention and cooling, many people like to drink mung bean soup and herbal tea. Although both mung bean soup and herbal tea are good, don't drink too much, not to mention drinking like drinking water.
From the perspective of Chinese medicine, people with cold constitution such as cold limbs, abdominal distension, diarrhea and loose stool should not drink more mung bean soup and herbal tea, otherwise it will aggravate symptoms and even cause other diseases. Especially for girls in menstrual period, it is not advisable to drink mung bean soup and herbal tea, so as not to harm the body and cause dysmenorrhea.
1 1, it is not advisable to sit on the wood or sleep at night.
As the saying goes:? No stones in winter, no trees 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.
In midsummer, the sweat glands of the body constantly secrete sweat to radiate the 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.
12, don't apply too much sunscreen or cool oil.
Many people mistakenly think that sunscreen can protect themselves from the sun, and naturally it can also prevent heatstroke. So whenever they go out, they should apply a thick layer or cool oil to cool down. In fact, these practices can not only prevent heatstroke, but will lead to heatstroke.
According to the analysis, thick sunscreen covering the skin will affect the sweat discharge, which will naturally lead to slow heat dissipation. Similarly, covering the whole body with cool oil will also reduce the discharge of sweat because of a cool feeling.
13, don't wear sunglasses that are too deep or too light.
Sunglasses can avoid the damage of ultraviolet rays to the eyes, but the lens color is too dark, which will affect the vision because of unclear vision; The color of the lens is too light, and ultraviolet rays will still hurt the eyes through the lens.
Therefore, the choice of sunglasses in summer should allow 15%-30% of visible light to pass through gray or green lenses, which can not only resist ultraviolet rays, but also have the best visual clarity. Don't choose sunglasses that are too dark or too light just to look good.
14, clothes that are not light in color are both radiant and cool.
Judging from the color of clothes, most people think it will be cool to wear white and light clothes in summer. In fact, white or too light-colored clothes will reflect ultraviolet rays and easily hurt the skin. Red light waves are the longest and can absorb a lot of ultraviolet rays in the sun, while other colors are relatively weak, so wearing red clothes in summer can block ultraviolet rays and prevent skin from being sunburned. If you wear black clothes indoors or on cloudy days, it will exert its function of rapid heat dissipation, and can quickly discharge the heat on the skin surface, making people feel much cooler.
In addition, when buying clothes, you should choose cotton clothes with soft texture. Clothes with loose styles and bright colors can play a cool and pleasant role.
15, don't be optimistic. I believe you can lose weight by sweating in summer.
It's hot, and you sweat a lot when you walk a little. Many ladies who love beauty secretly rejoice: Is my fat burning?
Truth: There is no scientific basis for sweating to lose weight. It is understood that there are about 3 million sweat glands in the human body. When heat causes blood vessels to dilate, water in blood transfers heat to the skin surface, and then evaporates with sweat to transfer heat to the surrounding environment. In the high temperature environment, the daily sweat output of human body can be as high as 8- 12 liters. Sweating in summer is just a physiological phenomenon that the body regulates temperature, and it has little to do with burning fat.
