Core Tip: In the hot summer days, many people can't wait to soak in the water all day, or drink a few large cups of iced drinks. However, sometimes it will make people more uncomfortable. Recently, the US “MSN Health Network†invited a number of experts to summarize some of the most unreliable methods of summer heat and check whether you have made a mistake.
1. Take a cold shower. Baru Gard, a California internal medicine expert, said that the cold water bath seems to be reasonable, but it is not. Sudden cold will cause the blood vessels to shrink rapidly. "Cool" will not enter the body, and may even lead to imbalance of immune mechanisms. Bathing with warm water is better than cooling in a cold water bath.
2. The sunscreen is sticky and does not coat more refreshingly. Deborah Garriman, a dermatologist in New York, said that ultraviolet light can pass through the clouds and sunburn the skin, making people feel hot. Therefore, even on cloudy days, apply a sunscreen with a sun protection index of at least 30.
3. Sprinkle water on the ground to cool down. In summer, people often sprinkle water on the ground and take away heat with their evaporation. However, this can only temporarily cool down, and for a long time, the indoor humidity increases, but it is even more stuffy. When evaporating, bacteria and dust on the ground will disperse into the air with water vapor, which is unhealthy.
4. Playing bare-chested. When the temperature is close to or exceeds 37 °C, the skin not only weakens the heat dissipation function, but also absorbs heat from the external environment. Wearing too little is also very easy to get burnt by UV rays. Therefore, the more you get to the heat, the more you can't wear vests, shorts or bare shoulders. When the temperature is higher than the body temperature, you can wear some light-colored thin long trousers and trousers to block the sunlight, which is good for heatstroke prevention.
5. Soak in the pool all day. In the summer, the beaches and swimming pools are often crowded with people who want to cool off. However, Philip Tirno, a clinical microbiology and immunology expert at New York University School of Medicine, said that it is better to take a warm bath than to take a hot shower. If the water quality in the pool is not good, it will also spread the disease.
