Top athletes would swear by it: Sleeping with your mouth taped off. There is also quite a lot of posting in the media around: sleeping with your mouth taped off to focus more on nasal breathing. It would help you sleep better. Better all around than with your mouth open. In any case, American dentist and sleep expert Dr. David E. Rye is clear:

“Sleep with your mouth closed. Your mouth is not meant for breathing during sleep. Breathing through your mouth dries out your mouth, irritates your throat and makes you more likely to snore and sleep apnea.”

But is that right? During the corona pandemic, a lot of people cried murder for not getting enough oxygen because they had to wear a mouth mask. So what is mouth tape good for? Is it healthy? Why would you tape your mouth and with what? All good questions we think. Time to dive deeper into it!

What are the benefits of sleeping with tape on your mouth?

When you look for true fans, you often read stories of top athletes, performance coaches and dentists. They point out the benefits to your health.

  • More calm: Breathing through the nose helps to calm your body and reduce stress.
  • Less snoring: When you are forced to breathe through your nose, your throat can stay open and you reduce the likelihood of snoring. This is one of the most well-known benefits of sleeping with a taped mouth.
  • Better sleep quality: Breathing through the nose is said to improve your sleep quality. This is because it helps you breathe deeper and slower, which gives your body more oxygen and helps you relax.
  • Less dry mouth: People who sleep with their mouths open or always breathe through their mouths will find that their mouths dry out more quickly. Breathing through your nose can reduce this.
  • Reduced allergies: Breathing through the nose filters and warms the air before it enters the lungs. This can help reduce the symptoms of allergies.
  • Fewer dental problems: Think cavities, bad breath and gum disease. If you breathe mostly through your mouth, your mouth dries out faster and there is less saliva. Its presence naturally protects your teeth.
