In the summer, the day is hot and sunny, UV radiation is at a very high level. When going out without protection, UV rays will damage the skin and health. So are there ways to block UV rays?

According to Dr. Pham Duc Tho - Aesthetic Center - Vinmec Times City General Hospital, first of all, it is necessary to mention the UV protection effect of sunscreen. In addition, sunscreen also helps reduce skin aging and the risk of skin cancer.
The simpler and more common measure that people often use is to use masks, sun clothes, wide-brimmed hats, ... However, medical masks are not enough to block the sun when going outdoors, so they should be left on. If you want to block UV rays better, you need to choose a cloth mask with enough thickness.
According to Doctor Pham Duc Tho, dark fabrics block UV rays better. Furthermore, sun-protective clothing with ceramic or denim-coated materials is better at absorbing and reflecting UV than linen, yarn, or wool. You should also pay attention to the thickness of sun protection clothing. Wearing too thick sunscreen will cause heat to the body.
In addition, another measure to help protect against UV rays is a sunscreen pill. Sunscreen pills have a protective effect on the whole body, but its protective effect is only achieved to a certain extent. Meanwhile, sunscreen has an effect on the areas of the skin where the cream is applied. Therefore, to achieve greater effectiveness, you should combine both oral sunscreen and sunscreen to increase the effectiveness of UV rays.
