4. Fetal Position
Sleeping all curled up into a ball with your knees drawn up and your chin tilted down might be comfortable but it’s probably one of the worst sleeping positions to consider as it can do a number on your back and neck.
The extreme curl of the fetal position can also restrict deep breathing. That considered, sleeping like a fetus can have you sleeping like a baby if you typically have problems with snoring or if you’re pregnant.
