Does black light cause cancer?

I recently bought a black light for my room, and a friend joked about it causing cancer. While I know it's probably not serious, it got me wondering, does black light actually cause cancer?

Black lights emit UVA radiation, which is much weaker than the sun's rays. Unless you are standing directly in front of high-powered industrial black lights for hours every day, it is not going to affect your health. Just focus on your daily lifestyle, workout, and sunscreen outdoors.

No, regular decorative black lights or the ones used in clubs do not cause cancer. They use long-wave UVA light which is generally safe for short exposures. There is absolutely no need to panic about this.

At this rate, the internet will tell us that looking at a tube light causes cancer. Don't worry, those party lights are safe. Just don't stare directly into them unless you want a headache, which is a much more real threat!

I totally get it, with so much conflicting information online, it is very easy to feel anxious about everyday things. Standard black lights are safe for home use and won't cause cancer. I hope this brings you some peace of mind so you can relax.

For home decorations, it is always better to use natural yellow or warm white LED lights which are gentle on the eyes and skin. If you have been exposed to strong UV lights and notice any strange skin patches or itching, please get it checked by a skin doctor immediately.
