In summer, when the temperature rises day by day, people drink cold drinks, air-conditioners, and cold water to wash their feet in order to cool off. As everyone knows, these "correct" methods that seem to cool down are actually not conducive to good health. Gao Yanxia, ​​director of the Department of Nephrology at the Provincial Hospital of Traditional Chinese Medicine, said that it is not as cool as summer. Misunderstanding 1: wash your feet with cold water
When summer arrives, many people find it most comfortable to use cold water to wash their feet. In fact, the sweat glands on the soles of the human body are more developed and more sweating occurs in the summer. Using cold water to wash the feet will cause the enlarged pores to suddenly close and block and increase muscle fatigue and tension after exercise. If you do this often, not only will your feet get cold but it will also lead to perspiration problems.
Experts suggest that summer heat and dampness are more common in the summer, and the spleen is most afraid of wetness. Moisture blocks in the spleen and stomach, and there will be no appetite, love, sleep, no spirit and so on. The yang in the summer is most prosperous. Using warm water to soak the feet can better stimulate the meridians and stimulate the body's viscera function. It helps to eliminate Shushi, prevent hot wind, encourage people's spirits, increase appetite and promote sleep. Misunderstanding 2: Drink plenty of green bean soup, herbal tea
In order to prevent heatstroke, many people like to drink mung bean soup and herbal tea. Mung bean soup and herbal tea are good, but do not drink more, not to drink.
Expert advice: From the perspective of Chinese medicine, people who are cold, such as limbs cold, abdominal distension, diarrhea and other symptoms, can not drink mung bean soup and herbal tea, otherwise it will aggravate the symptoms, and even trigger other diseases. Especially in the menstrual period of women, should not drink mung bean soup and herbal tea, so as not to harm the body, causing dysmenorrhea.
Myth 3: Cold and Cold Drinks
Due to the hot summer days, many people like to eat a lot of cold dishes, cold food, watermelons, cold beer, cold drinks and so on. Experts pointed out that in the hot summer days, the human body is actually in a state of external heat and cold. If you eat too much cold food and cold drinks, you can easily cause gastrointestinal disorders.
Experts suggest that summer drinks are still dominated by hot drinks. Because the hot water enters the human body, although it feels hot at the time, the central thermal neurons reflect the pores of the skin's capillaries and expand rapidly. The blood flow is greatly increased. The secretion of sweat glands is increased, which promotes perspiration and brings out the heat inside the human body. In vitro, the temperature actually drops, and this coolness is long-lasting. Misunderstanding 4: Prolonged use of air-conditioning cooling
If you spend too much time in your room, you may feel sore, apathetic, and have a loss of appetite. Sometimes you may experience nasal bleeding due to dryness of the nose, or a cold, fever, or even bronchitis, pneumonia, and gastroenteritis.
Experts suggest that indoor temperature should not be lower than 27°C, and the temperature difference between indoor and outdoor should not exceed 8°C. Open air-conditioned rooms do not close doors and windows for long periods of time. Always ventilate.
Myth 5: Lightweight and cool chemical fiber fabrics
In summer, many beautiful clothes are made of synthetic fabrics. They are light in weight, cheap in price, and attractive in variety. They are very popular with young families, especially Amy ladies. In fact, the body sweats a lot in summer, and although chemical fiber fabrics are lighter and thinner, they are poor in water absorbency and breathability, and it is difficult for the skin to radiate heat through sweat evaporation. Therefore, it is not cool to wear such fabrics in summer. At the same time, excessive retention of sweat will also cause skin secretions to spoil and ferment, combined with the synthetic fiber components to stimulate the skin more, easily induced allergies or a variety of dermatitis.
Expert advice: natural fibers such as cotton, linen, and silk are the best choices for dressing in summer. Silk clothes are very good skin-friendly, light weight, thin thickness, summer wear both comfortable and beautiful, but also feel cool throughout. Cotton clothes absorb sweat, have good air permeability, and the fabric is soft and not stiff. Hemp clothing should have a loose molecular structure, light texture, large pores, and very good breathability and water absorption. The thinner and more sparsely clothed clothes, the lighter the clothes, the cooler the clothes are.
Misunderstanding 6: Light colored clothes are both cool and cool
People generally think that wearing white, light-colored clothes in summer can be cool. Actually, white or light colors can reflect ultraviolet rays, which can easily damage the skin. The red light wave is the longest, can absorb ultraviolet rays in sunlight, and other colors are relatively weak, so wear red clothes in summer can prevent ultraviolet rays and prevent skin from being sunburned.
Expert advice: To a certain extent, light-colored clothing can cause skin cancer for a long time under the irradiation of ultraviolet rays. In particular, dazzling cotton clothes may contain fluorescent brighteners, which will reflect harmful light to people's protection. To the face. Darker clothes such as red or navy are much safer. Therefore, it is best to wear red or navy blue clothes in summer. In addition, you can wear black clothes indoors or on cloudy days. Black has a fast heat dissipation function and can quickly remove heat from the skin surface.
