What are some misunderstandings about cooling off in the heat
● Drinking more cold beer can relieve the heat?
On a hot day, drinking cold beer does feel cool. However, drinking too much can make the mouth dry and the whole body warm. Beer contains alcohol. If you drink too much, the alcohol content in the human body will be too high, which will cause people to feel “hot”, and the symptoms of thirst and sweating will also increase.
●The earlier the morning exercise, the better?
Many people believe that the earlier the summer morning exercise, the better. In fact, the air is not fresh before dawn or when it is very bright, which is not conducive to fitness. The data shows that before 6 o’clock in summer, the pollutants in the air are the least likely to spread, which is the peak period of pollution. Before sunrise, there is not much fresh oxygen around green plants because there is no photosynthesis. Therefore, the morning exercise time in summer should not be earlier than 6 o’clock.
●The air conditioner should be kept at a constant temperature?
Many people are used to setting the temperature at a certain value when using air conditioners in summer. Experts suggest that by constantly adjusting the room temperature, people’s physiological thermoregulation mechanism can often be in a “stressed state”, thereby improving people’s ability to adapt and self-protection, and not susceptible to colds or other room diseases. In addition, you must not hide in the air-conditioned room all day, artificially causing the body state of “cold fire”.
●The darker the sunglasses, the better the eye protection?
It is wrong to think that darker shades of sunglasses are better for eye protection. If the lens color is too dark, it will seriously affect the visibility and cause eye damage. Experts suggest that it is best to choose sunglasses lenses that can pass through 15% to 30% of visible light, and the color of the lenses is preferably gray or green.
