What are the misunderstandings about summer health care?

Myth 1: Drinking beer can relieve the heat

On hot days, when beer (especially cold beer) is drunk into the mouth, there is indeed a cooling feeling. However, drinking too much can still make people feel dry in the mouth and throat, and the whole body feels hot. The climate in summer is hot, and the human body sweats more, consumes more, and gets tired easily. If you continue to drink beer, the "hot" feeling caused by alcohol will continue, and the phenomenon of thirst and sweating will become worse, which not only affects Without the purpose of relieving summer heat, it will reduce people's thinking ability and work efficiency, and even cause errors and accidents at work.

Beer cannot relieve the heat. If you want to relieve the heat, you should still drink boiled water, or drink mung bean soup or sour plum soup.

Myth 2: The fewer clothes you wear, the cooler you will feel

Generally speaking, in summer, the smaller the area covered by clothes, the faster the body dissipates heat, so the cooler you feel. But we can’t generalize and think that “it’s coolest to go shirtless in the scorching heat of midsummer.” Studies have shown that going shirtless can only increase skin radiation and conductive heat dissipation when the skin temperature is higher than the ambient temperature. On hot summer days, when the highest temperature is generally close to or exceeds 37°C, the skin not only cannot dissipate heat, but also absorbs heat from the external environment. It absorbs heat, so you will feel hotter when you are shirtless, and it is easy to develop skin diseases. In this sense, during the hotter summer months, men should not go shirtless, and women should not wear short skirts.

Myth 3: The darker the sunglasses, the better they can protect your eyes

When walking or riding a bicycle in summer, you will indeed feel a "coolness" when wearing sunglasses, which can protect your eyes. But when the sun is scorching at noon, many people think that the darker the sunglasses, the better they can protect their eyes. In fact, this view is wrong. Lenses that are too dark in color will seriously affect your visibility. Your eyes will be easily damaged due to the difficulty of seeing. They will not protect your eyes, but will affect your safety. The criteria for choosing sunglasses in summer are: the lenses should be able to pass through 15% to 30% of visible light, preferably dark tea. In this way, they can not only resist ultraviolet radiation, but also have the best visual clarity and minimize the color change of external objects.

Myth 4: Sweating more is better for health

Sweating in summer is good for health, but you should not sweat excessively, otherwise you will easily suffer from heat stroke. On the one hand, sweating can evaporate and dissipate heat to maintain a constant body temperature; on the other hand, it can discharge a variety of harmful metabolic wastes, such as lactic acid, carbonic acid, creatinine, urea, and bacterial toxins. Therefore, as long as you can sweat a little and urinate easily in summer, you are less likely to get sick. If there is no sweating and oliguria, it is often a precursor to heatstroke. The elderly's sweat glands atrophy, so they are prone to heatstroke.

Therefore, when you sweat a lot in the hot summer, you should replenish water and salt at any time, in small amounts and often, and do not drink too much if you are thirsty. You should drink more vegetable soup for three meals on weekdays, and eat more fruits and vegetables that are rich in water and vitamins and potassium salts, such as watermelon, cucumber, spinach, loofah, etc.

When exercising in summer, you must first evaluate your cardiopulmonary function and rule out underlying diseases. Do not exercise excessively in hot weather, otherwise it may easily cause sudden death from myocardial infarction. In summer, it is best to choose outdoor and well-ventilated venues to exercise, and the exercise time can be appropriately shortened.

Myth 5: Go to bed late to enjoy the coolness on summer nights

Some people think that if the temperature drops in the second half of the night before going to bed and getting up late the next day, you can have a better rest. However, according to the rules of the human body's "biological clock", the best time to sleep is 22 to 23 o'clock. 5 to 6 o'clock in the morning is the "climax" of the biological clock. It is the best time to get up at this time. Therefore, you should live on time in summer.

Misunderstanding 6: The more bitter the herbal tea is, the more it will cause internal heat

"The more bitter the herbal tea, the more effective it is." When drinking herbal tea in summer, many people think that "the bitter taste of herbal tea is good for the disease." " attitude, they only look for herbal teas that are too bitter to swallow. In fact, bitterness is not the criterion for measuring the effectiveness of herbal teas. Blindly seeking "bitter" may damage the spleen and stomach. Judging from the effects of herbal tea, it is mainly divided into two types: clearing fire and removing dampness. To drink herbal tea for the purpose of clearing fire, you can drink some bitter tea, which will have better effect. If the main purpose is to remove dampness, there is no need to ask for "bitterness", because bitter Chinese medicinal materials are generally cold and can easily damage the spleen and stomach.

Warm reminder that although herbal tea is a good refreshing drink in summer, it is also a traditional Chinese medicine decoction, so you must drink it in moderation. In addition, the spleen and stomach functions of the elderly are relatively weakened, and the spleen and stomach functions of infants and young children are not yet perfect, so it is not suitable to drink herbal tea, otherwise it may easily cause side effects such as indigestion, cold and painful epigastrium, and loose stools after eating less.
