How do you know if your shirt is thick enough to protect against the sun?

Doctor-CKII Le Vi Anh , Department of Dermatology - Dermatology, University of Medicine and Pharmacy Hospital, Ho Chi Minh City replied: Currently, the weather is hot and sunny over a large area, the intensity of ultraviolet rays (UV) increases, which are harmful factors to the skin. When going out, you should pay attention to choosing clothes, sun-protective skirts, long-sleeved jackets, thick cotton material to cover and avoid sunlight from penetrating. Dark-colored clothes will help protect better than light-colored clothes.

You can use a flashlight to check whether the thickness of your clothing is enough to protect you from the sun.

To know if the outfit is thick enough to block the sun, you can use a flashlight to shine through it. If no light gets in, you can rest assured that it is sufficiently protected from the sun.

In addition, you should wear a hat with a brim of over 3 cm to ensure coverage on the face, neck and chest. Use sunscreen with an SPF of 30-50. Under normal conditions, you should apply sunscreen every 2 hours, 20-30 minutes before going out.

In addition, you can take sunscreen pills. With the main ingredient being antioxidants, sunscreen pills help prolong the exposure time to UV rays that can harm the skin, for example 30 minutes instead of 15 minutes.
