Inside the house, building, bedroom or office It may seem like a shelter from the sun. And good UV protection Because there are walls, windows, curtains, UV protection But ... you might be thinking wrong. Because even though inside the building You can not get away from these things 100 percent, and even if the glass used to make windows in the house. Office building Or current car glass will have UV protection properties, but it only protects from most of the UVB rays. But cannot avoid all UVA rays
Because UVA is a very powerful long wave radiation. Therefore able to creep into the building or the car as before And it is also a ray that penetrates into our deep skin cells more than UVB as well. And it is UVA that will destroy the collagen and elastin layer in the skin. It causes wrinkles easily. And also at risk of skin cancer
However, besides the sun and UV rays Blue light from electronic devices such as LED screens. Light from the screen of mobile phones. Although there is not enough research to confirm that it is harmful to skin cells. But it is a matter that should not be overlooked. Wherever possible, spend a little less time spending on these digital screens in the light.
So you can see that even if we stay inside the house all day without going out in the sun at all. It does not mean that our skin is immune from the sun and UV rays, so applying sunscreen is a necessity that should not be ignored. And the sunscreen used should have an SPF of at least 30 or more to protect the skin.
