Will UV light in bug zapper hurt you?

The abbreviation for ultraviolet is UV, where the ultra -means "above, beyond". In the solar spectrum, ultraviolet light has a higher frequency than visible light.

1.UVA (wavelength 400nm ~ 320nm, low frequency long wave, there’s a lot in sunshine light, mainly used for curing such as printing, manicure, dental UV lamp, which will not cause acute damage, but long-term exposure will tan, sun wrinkled skin , so do not look at it for a long time. This band is the most attractive to mosquitoes and has the least damage to the human body, so the mosquito killer lamp adopts this band. However, when installing, keep a distance from the human body to avoid looking directly at a short distance for a long time.)

2.UVB (wavelength 320nm ~ 280nm, medium frequency medium wave, will hurt skin).

3.UVC (wavelength 280nm ~ 100nm, high frequency short wave, the best band for bactericidal effect, can burn the skin, generally blocked by the ozone layer).

UV rays are not all bad. When they irradiate the human body, they can promote the body to synthesize vitamin D to prevent rickets. This is the reason why let children exposed to the sun usually. Ultraviolet rays also have a bactericidal effect, and wards in hospitals use ultraviolet rays to disinfect. However, too strong ultraviolet rays will harm the human body, so you should pay attention to protection.
