In summer, many people will wear hats when they go out. One is for concave shape, and the other is for sun protection. Can wearing a hat prevent ultraviolet rays? Can wearing a hat prevent sunburn? Let's learn about it with Xiaobian!
Can wearing a hat prevent ultraviolet rays
Wearing a hat can block part of the ultraviolet rays, which belongs to physical sunscreen, but it is not that wearing a hat does not need sunscreen, because the ultraviolet rays will also refract from the ground to the face, so the sunscreen with SPF30 can not be saved.
Sun visors are UV resistant. There are UPF hats on the market, such as coolibar. Some hats and clothes on the market have been marked with UPF index, ranging from 15 to 50. The higher the value is, the stronger the sun protection is. But the effect is not as powerful as you think. In other words, even if you wear a sun hat, sunscreen can't be omitted.
Can wearing a hat prevent sunburn
In summer, wearing a hat alone can't prevent the sun completely, or it will be tanned.
In summer, strong sunlight will have a series of adverse effects on the human body, making the skin tan, leading to cataract, sunburn and skin cancer. In the strong sun, it is necessary to wear a cool hat when going out. It can not only prevent the hot sun, protect the mind, but also help to prevent heat and health. The most intense sun exposure is from 10am to 3pm or 4pm. Sun visors are very effective against direct sunlight, so it's best to wear them on both sunny and rainy days. Always wear a hat on the boat, on the beach and outdoors.
There are many kinds of cool hats, such as straw hat, cloth hat, sun hat, etc. Each kind of sunshade has its own advantages. Straw hat has better performance of heat dissipation and heat resistance. Choose cool hat that can cover the sun, heat dissipation, ventilation and perspiration, but good ventilation is very important. It can avoid the formation of high temperature and humidity in the hat. The best color of cool hat is white, which has the strongest reflection ability and the weakest absorption ability.
Misunderstanding of sunscreen
Mistake 1: when it comes to sun protection, many people think that sun protection is sun protection. In fact, there are many places that need sunscreen in our life, such as working in front of the computer for a long time and using mobile phones frequently, so we need to take some protective measures for the face skin.
Myth 2: only when the sun is strong, you need to use sunscreen. This equates ultraviolet with sunlight. In fact, ultraviolet rays in the sun, even in mist, cloudy days and cloudy weather, still exist, so always pay attention to sun protection.
Myth 3: you don't need sunscreen in seasons other than summer. Even in seasons other than summer, ultraviolet rays can take away moisture from the skin and destroy the skin tissue. Therefore, sunscreen is a task to be done all year round.
Myth 4: the higher the SPF of sunscreen products, the better the sunscreen effect. This is wrong. Sunscreen products with too high SPF are easy to block pores, which is not conducive to perspiration, causing excessive burden on the skin. Therefore, they will feel uncomfortable after being applied, and are not suitable for daily use. The correct way is to choose products with different SPF in different occasions and according to different requirements.
