Do I have to put on sunscreen even if I live indoors?

pu1. I heard that it's good to apply sunscreen because you can get ultraviolet rays inside

OK

pu2. Sunscreen itself is not good for your skin, so it's better not to apply sunscreen unless you're under direct sunlight. Some people read blogs and company advertisements and say that you can apply inorganic sunscreen because it's okay, but it's better not to apply it because it's toxic
