“Mask shell” helps you get into the habit of abdominal and nasal breathing and boost your immune system.

Self-protection plans against new coronavirus are both “external measures” to prevent infection with mask and “internal measures” to boost the immune system and make the body more resistant to infection.
Abdominal breathing is said to be an effective way to boost the immune system, additionally nasal breathing can also be expected to increase the effectiveness.

However, even if you know that abdominal breathing and nasal breathing are effective, it is difficult to adopt them because of the breathing on your own that you have learned in a long lifestyle.
So we suggest a health method with a nasal mask to focus your attention on your nose and learn how to breathe naturally and correctly.


The basics of abdominal and nasal breathing to keep your

physical condition

1. Putting on Mask Shell and focusing your attention on your nose

2. Breathing out through your nose in your comfortable posture.

3. Breathing through your nose and counting the numbers 1, 2, 3, 4 in your mind while

pushing out your belly

4. Pulling in your belly as you lift your organs and breathing out slowly (Counting 8)

through your mouth (Through your nose also OK).

5. Keeping doing 3 and 4 until relaxing
It is effective to do this frequently
