Can you get a sunburn indoors?
Many people may be surprised when asked, "Can you get a tan indoors?" However, UV rays actually enter the room through window glass, so you can get sunburn even indoors.
Ultraviolet light is a type of electromagnetic radiation emitted by the sun, and is divided into UV-A, UV-B, and UV-C depending on wavelength.
UV-A reaches deep into the skin and causes wrinkles and sagging. UV-B reaches the dermis and causes age spots and freckles. UV-C has the shortest wavelength and is mostly blocked by the Earth's atmosphere, so it never reaches the ground.
Window glass blocks all UV-C, but allows some UV-A and UV-B to pass through. The amount of UV rays that passes through the window varies depending on the type and thickness of the window glass.
In general, frosted glass or window glass with UV protection processing transmits less ultraviolet rays than transparent window glass.
People who are at risk of sunburn indoors are those who spend a lot of time near windows. People living in sunny rooms should also be careful.
To prevent sunburn indoors, the following measures are effective.
・When spending time near windows, protect yourself from UV rays by wearing a parasol or hat.
- If you live in a sunny room, use blackout curtains or blinds.
- Apply UV protection to window glass.
・Apply sunscreen.
We recommend sunscreens that are effective in blocking UV-A and UV-B.
SPF is an index that indicates the protective effect against ultraviolet B rays (UV-B), and the higher the number, the higher the protective effect. PA is an index that indicates the protective effect against ultraviolet A waves (UV-A), and the higher the number of +, the higher the protective effect.
By preventing sunburn even indoors, you can prevent skin problems such as age spots and freckles. In addition, UV rays increase the risk of skin cancer, so it is important to take precautions against UV rays on a daily basis.
What are the effective methods for indoor UV protection?
I'm sure many of you have heard the question, "Can you get a sunburn indoors?" In fact, there's a good chance you can get a sunburn even indoors.
