Matters needing attention in hot weather

1, ultraviolet light. Summer gives people the feeling of enthusiasm, unrestrained, sports, etc. Under the scorching sun, ultraviolet radiation is strong, so we can't avoid some outdoor activities. But pay attention to the time in the hot sun. The advantage of ultraviolet ray is sterilization, which is beneficial to the synthesis of vitamin D and promotes the development of bone tissue, but at the same time, ultraviolet ray also does a lot of harm to human skin and eyes. (Coping method: avoid spending too much time outdoors, use sun umbrellas and sunglasses to reduce the harm of ultraviolet rays to us)

2. water. Drinking water often, the human body secretes sweat through the skin and consumes water in the human body. If you are thirsty, you will not drink water. Due to the influence of high temperature, the human body will produce a series of physiological reactions, leading to listlessness and loss of appetite. It can be properly adjusted by cold drinks and beverages, but it is not allowed to eat too much. Drinking too much will affect appetite, which will seriously damage the spleen and stomach or lead to gastrointestinal dysfunction.

3. Salt and vitamins. In hot summer, people sweat a lot, and the sweat secreted by the skin contains sodium chloride, which not only supplements water, but also supplements salt. Vitamins are also essential, such as watermelons, cucumbers and tomatoes. You can also drink some juice.

4. Adjust your diet. Perhaps it is the overheated weather that makes you feel unwell and listless, so you should eat some light and digestible food and eat less greasy or fried food. Seasonal vegetables, assorted fruits, seafood and fish are all good choices, and protein should be supplemented appropriately to meet human metabolism.

5. Don't take a cold bath. If you don't take a cold bath with a large temperature difference, your body temperature will suddenly drop, which will easily lead to cold, joint pain, numbness of limbs and other adverse reactions, and may also lead to some other hazards.

6. Maintain the regular pattern of daily life. Not staying up late and getting enough sleep are effective measures to keep the human body in the best condition, and summer is also an effective measure to prevent heatstroke. Don't lie on the air outlet of air conditioner and the air outlet under the electric fan when sleeping.
