Moving on from side sleeping to the back, the soldier position involves lying on your back with both arms down by your side. As anyone who snores (or has shared a bed with a snorer) knows, sleeping on your back can often result in less airflow, and thus, snoring.

Breathing properly is essential to a good night’s sleep, so if you sleep on your back and notice you’re consistently waking up feeling groggy, it could be worth experimenting with sleeping on your side. Other than that, this is another position where having the right pillow to support your head will make all the difference.

According to Idzikowski’s research, the soldiers of the sleep world are typically quiet, reserved, and hold themselves and others to a high standard.
