1. [+212, -6] There's a reason people open their mouths while asleep... because they can't breathe through their nose. What do you think happens when you block the mouth, then?

2. [+38, -3] Just wear your face mask to sleep...

3. [+21, -3] I guess you're just going to die if you have a plugged-up nose

4. [+22, -6] I know someone who sleeps with paper taped to their mouth in the winter and they said they don't wake up with a dry mouth or catch colds as easily anymore

5. [+13, -0] Wake up, people. Who do you think these celebrities are that you're actually copying what they do? They're just humans like the rest of us just with a more decent looking face.

6. [+12, -1] You don't need these special mouth tapes. Just get regular paper tape and make sure you don't block your mouth entirely. You should still be able to breathe and talk through it, but it'll be enough to hold your mouth from spreading when you're asleep. I find that I wake up in the morning without as much dryness and soreness and can't sleep without it anymore. Just get paper tape for a dollar and it'll last you six months.

7. [+8, -2] I suffer from sleep apnea which causes my mouth to open automatically when I'm asleep. These mouth tapes aren't so strong that you can't open your mouth at all, but it helps with the dryness in the morning. Dry mouth is the cause of a lot of health issues.

8. [+5, -0] When I saw Shinji use one, I thought she was crazy. What if you die in your sleep?

9. [+8, -4] I've been using mouth tapes for three years and enjoying the benefits of it. I recommend it to anyone.

10. [+5, -1] What a stupid trend ㅋㅋㅋ who even thought of this? I don't think you need an expert to tell you that this is dangerous. Please don't copy these trends blindly or you just might end up dead.

11. [+4, -0] I think anyone can see that this looks dangerous... you could die if you do it the wrong way

12. [+4, -0] Please don't copy these things~ if you have issues with your sleeping, please go consult with an expert
