Is it necessary to apply sunscreen when staying at home?
If you have to work from home and not go out, many people may wonder if they still need to apply sunscreen.
Some people may think that since they are not exposed to the sun, there is no need to apply it. However, some people may still be concerned about UV light from household electrical appliances such as fluorescent lights, televisions, or computer screens.
In reality, these devices emit almost no UV radiation, or if they do, it is at a very low level, and does not have any harmful effects on the skin. However, the concern is probably UVA radiation from light that leaks in through windows or glass. For clear glass, UVA radiation can pass through up to 75%, while tinted or reflective glass can pass through 25-50% (UVB radiation cannot pass through glass).
Therefore, even though home appliances hardly emit UV rays.
If you want to protect your skin from sunlight that may pass through windows or https://ufabet999.app glass while you are indoors, it is recommended that you always apply sunscreen.

Including avoiding being in areas where sunlight shines will help prevent UVA rays from harming the skin.

Most UVC rays are absorbe, reflecte, or destroyed by the Earth’s ozone layer, so they do not have much effect on the skin. Therefore, we will talk about the first 2 types of rays: UVA and UVB, which are the main causes of various skin problems.
1. Ultraviolet A or UVA rays
can divide into UVA-I and UVA-II. In sunlight, there is up to 95% UVA. UVA rays are harmful to the skin, causing wrinkles, sagging skin, darkening of the skin, dark spots, and the creation of free radicals. They indirectly affect DNA, genetic mutations, and can cause some types of skin cancer.
2. Ultraviolet B or UVB rays
cause sunburn, skin inflammation, premature aging, and are also a major cause of skin cancer if the skin is expose to sunlight frequently. Especially at noon or in the afternoon, or when the sky is clear with few clouds, and without good protection.
