Q: How harmful is ultraviolet radiation?
A: Ultraviolet radiation can be divided into three types: long wavelength (UV-A), medium wavelength (UV-B) and short wavelength (UV-C). Among them, UV-B irradiation on the skin, will make the skin slightly reddish, gradually turning into wheat color, that is, “suntan”, serious blisters, which is what we call “sunburn”.
Q: When is ultraviolet the strongest?
A: Many people think that the strongest time of ultraviolet radiation is midsummer, in fact, April to June, that is, spring and summer is the strongest time of ultraviolet radiation in a year, and in a day, the strongest time of ultraviolet radiation is from 10:00 a.m. to 3:00 p.m. We should try to avoid going out during this time period. If we need to go out for a long time, adequate protection is absolutely necessary.
Q: Should babies spend less time in the sun?
A: People spend a lot of time outdoors in their life, and the most suitable time for babies to get sunshine is about 5 years old. But the deterioration of the environment destroys the ozone layer, which can not effectively block ultraviolet rays. Therefore, it is better to let babies have less exposure to strong sunlight or take good protective measures when they go out.
Q: Do you need to wear a long-sleeved shirt to go out in summer?
A: It’s good to wear it, but because the baby’s thermoregulation function is not perfect enough, wearing too much will raise the body temperature and cause prickles, so you don’t need to wear long-sleeved shirts for short trips, but it’s better to wear a wide-brimmed hat and daub the baby’s sunscreen on the exposed skin. Of course, sunshade umbrella, trousers, car sunshade are indispensable preparation for taking baby out.
Q: What is “SPF”, “PA”?
A: Both SPF and PA refer to the ability to resist ultraviolet radiation. SPF is the defense index of UV-B, PA is the defense index of UV-A. The higher the index, the stronger the defense ability of UV-B.
Q: How to choose sunscreen with different index?
A: Mothers should choose sunscreen with different index according to different places of play. When walking, choose SPF 15 sunscreen; when climbing mountains or going to the seaside, choose SPF 25 sunscreen; if you go to a tourist attraction with strong sunshine, you’d better choose SPF 30 sunscreen with longer duration, but sunscreen with high SPF value (such as SPF 50) is more irritating to your baby’s skin, and you’d better not choose SPF 25 sunscreen.
