Do sleep masks work?

They block the light well, but does anyone else feel super suffocated wearing them? I get anxious thinking my skin can't breathe or that I'll miss an emergency because my eyes are covered. Let me know if you guys also feel this pressure.

In our days, we did not need such artificial masks to sleep. If you have trouble sleeping, wash your feet with cool water and put a drop of castor oil on your soles before bed. A naturally dark and quiet room is much better than tying tight cloth on your face.

I have been using silk sleep masks during my train travels for twenty years now. They really help your eyes relax and prevent early morning light from waking you up. Don't worry, they are quite safe and work beautifully if you travel a lot like me.

I used sleep masks for a year to block light because I was having severe headaches and couldn't sleep. It turned out I had high blood pressure, not a sleep light issue. Please get a proper health checkup if you are suddenly finding it hard to sleep naturally.
