Choosing the right sleeping position is the most important thing what you need to consider to help you sleep better and wake up more rested.There are a number of sleeping positions that you might find comfortable and at the same time promotes proper blood flow. Having a correct sleeping position would prevent that stiffness and soreness you might experience during mornings.
1. Sleeping on your side (with arms on the sides or with legs bent)
2. Sleeping on your back (with arms by the side or with arms by the head)
3.Sleeping on your abdomen.
The best sleep position is: Sleeping on your side with the knees bent and a pillow between the knees, and; sleeping on your back with a pillow under the back of the knees. The body pillows are key to maintaining the spine’s natural curves during sleep.
The worst sleep position is: Sleeping on your stomach because this position results in overextension of the lower back and awkward neck and shoulder postures.
