Sunbathing is good for your health, but too long will do harm to your health. How to sunbathe correctly?

Sunbathing can promote the production of vitamin D, which can help the body absorb calcium. Sunbathing can raise the body surface temperature and dilate blood vessels, so it has the effect of lowering blood pressure. Sunbathing outdoors can shorten the time of using eyes and prevent the eyesight from being too tired. On the other hand, sunlight can stimulate the production of dopamine, which can effectively prevent myopia. For people with poor sleep quality at night, it is better to bask in the sun during the day. Because sufficient light can inhibit the secretion of melatonin and make people more energetic during the day. In this way, at night, after turning off the lights, melatonin can be completely released, which can make people fall asleep quickly. When basking in the sun, it is best not to put the glass in the sun, because the glass will block ultraviolet rays, and it will not achieve the effect of health preservation through the glass.

It is best to bask in the sun outdoors, so that your skin can really get in touch with the sun and be fully exposed. For example, if the newborn has jaundice, the doctor suggests getting more sunshine. At this time, you should take the children out of the house, not through the glass, otherwise it will have no effect. The sun's rays at noon are poisonous, especially in summer, which will peel off in a few minutes. The time to bask in the sun is also particular. The morning sun can be between 6: 00 and 10: 00, and the afternoon sun can be between 4: 00 and 6: 00. At this time, the sun's light is mild, and the damage to the skin is weak, and it will not get sunburned. Sunbathing time should also be controlled.

Never bask in the sun for too long, or you will be affected by ultraviolet rays and your skin will be injured. The best time for sunbathing is about 15 minutes. You can't stay in the sun. If you get too much sun, you will get sunburned easily. In summer, people like swimming. If they stay in the water for a long time, their skin is more vulnerable to injury. When swimming, you can apply waterproof sunscreen on the exposed parts of your body, which can protect your skin from ultraviolet rays for a certain period of time. Compared with adults, children need sunshine more, but they are also more likely to get sunburned than adults. Children had better wear sunscreen in the sun, especially when swimming.

They must reapply it every half hour. Don't be overexposed to the sun. When the weather is hot, you can sunbathe for 5- 10 minutes at a time. After a long time, it is easy to turn people's moles into melanoma or skin cancer. Be sure to apply sunscreen to cover the mole when you are in the sun. It is best to wear red clothes when basking in the sun, because the long-wave radiation of red clothes can quickly "eat" the short-wave ultraviolet rays with strong lethality. It's best not to wear black clothes. When basking in the sun, you should take off your hat and gloves, expose your skin as much as possible, and let the sun get close to your skin.
