Experts analyzed that the ultraviolet rays in the summer sun are relatively strong, and the human body is exposed to sunlight for too long, and it is prone to acute sunburn. Acute sunburn will not be immediately manifested after exposure to the sun. It is often exposed to skin for 6 to 12 hours after exposure to large areas of erythema and peeling. Severe blistering, edema, burning, and fever may occur in some people. The symptoms of blisters ulceration.
In summer, people like to swim to cool off summer, but ignore the days of soaking in rivers or swimming pools during the day, the skin is more prone to sunburn. Because the ultraviolet rays are reflected in the water, they can pass through a depth of more than one meter. And because water reflects sunlight, its intensity will increase, and people will receive double ultraviolet radiation in the water.
Experts advise that before playing, be careful to apply waterproof sunscreen on the exposed parts of the skin. Children should choose a child-specific sunscreen. The ultraviolet rays in the sun are the strongest between 12 noon and 2 pm, and you should avoid swimming outdoors during this time. After half an hour or an hour of water, it is best to re-apply sunscreen. Compared with adults, children's skin is thinner, their body resistance is poor, and they are more likely to be sunburned. Therefore, preparations before the play should be paid more attention.
When mildly sunburned, the skin will be reddened at the time. In severe cases, the skin will have a burning sensation and a painful sensation. It is like a burn, which is an acute reaction to the skin suffering from damage. At this time, it is best to use ice to eliminate pain, and then use calamine lotion to wash the sunburn skin, play a role in heat dissipation, convergence, anti-inflammatory, etc., in addition to reducing symptoms, but also prevent ultraviolet rays from further irritating the skin. In general, when the skin is sunburned, the body will speed up metabolism and peel off as soon as possible to restore normal skin.
For the prevention of sunburn during swimming, experts recommend the following prevention methods:
(1) When swimming to the water, all exposed parts should be waterproof sunscreen, which can protect the skin from UV rays for a certain period of time and to a certain extent.
(2) After diving, surfing, swimming, you can apply sunscreen again as needed.
(3) UV has advantages and disadvantages. Appropriate sun exposure not only promotes the absorption of calcium in the body, enhances bone density, but also allows the skin to produce a certain amount of melanin, which enhances the skin's ability to defend against ultraviolet rays. Therefore, experts say that The idea of ​​isolating ultraviolet light is ridiculous, and proper sun exposure to ultraviolet light is good for your health.
(4) When you are in the sun, avoid the strong noon, you can choose 30 minutes before morning and after 4 pm, 30 minutes in the morning and evening.
