Cat help - researching litter

I've had two cats for about 12-13 years, and I'm just now wondering how safe is the cat litter I'm using for my health and the cats? I use Tidy Cat clumping litter and I'm not sure if any other long time cat owners are using this brand or if you've heard from other people that another cat litter is better?

I've googled this topic and I can't find any long term studies on the effects of cleaning cat litter or what types of litter they studied. I've found articles talking about silica clay and silica can cause problems.

I think I have too much free time on my hands and may be overthinking this topic. It's just now I can't stop worrying about my cats little lungs and my own! I'm 99% sure that using Tidy Cat and not wearing a mask isn't going to kill me or cause lung damage because millions of other pet owners are probably using this brand of clumping litter and if people were becoming sick and dying people would have talked about it.
