In my opinion , everyone have their own “natural” positions because it just like your habits.
So maybe we can focus in which positions will make us sleep comfortably and healthy
1.Not recommend face down your pillow.
2. It is not recommended to curl up and sleep.
3.In addition, lying on the side of the bed is suitable for some special groups of people.
Which group ?
- Severe snoring
- A person with a disease on the back of the neck
- Patients with gastroesophageal reflux are advised to sleep on the left side
- Pregnant people, recommended left bedroom sleep
The most recommend : just lying on your bed.
