FAQ about uv light

What are the different types of UV rays?
There are three types of UV rays: UVA, which are responsible for skin ageing, UVB, which cause sunburn, and UVC, which are blocked by the Earth's atmosphere.
How to protect oneself from UV rays?
To protect oneself from UV rays, it is recommended to wear broad-spectrum sunscreen, protective clothing, a hat and sunglasses, and to avoid the sunniest hours of the day.
Do clouds block UV light?
No, up to 80% of UV rays can penetrate through clouds, which is why it's crucial to protect oneself even on cloudy days.
Are children more vulnerable to UV rays?
Indeed, children's skin is more sensitive to UV rays, which makes them more susceptible to sunburn and long-term damage.
Do windows block UV rays?
House or car windows block the majority of UVB rays, but they allow a significant amount of UVA rays to pass through, hence the importance of wearing sun protection, even indoors.
Does UV light exclusively cause skin cancer?
UV rays are primarily responsible for skin cancers, but they can also damage the eyes and increase the risk of cataracts.
Does tanning protect against UV rays?
Tanning is primarily a defensive reaction of the skin to the damage caused by UV rays. It does not protect against the long-term effects of ultraviolet radiation.
