Sleep Follows the Same Rules

During sleep:
- We cannot consciously adjust posture
- Breathing quality determines muscle tone and alignment
When mouth breathing occurs at night:
- Breathing becomes shallow
- Neck and shoulder muscles remain tense
- Head position becomes unstable
As a result:
- Neck strain
- Morning stiffness
- Chronic postural imbalance
become more likely.
Why Back Sleeping Is Recommended
Back sleeping is the preferred position.
When lying on your back:
- Blood flow and mucus are distributed evenly
- Nasal passages are less likely to become congested
- Nasal breathing is easier to maintain
This position best supports both breathing and posture.
If Back Sleeping Is Too Difficult
Some people find back sleeping uncomfortable.
In such cases:
🔳Side sleeping is acceptable if mouth taping is used.
The priority is not achieving a “perfect” posture, but maintaining nasal breathing during sleep.
