The best position to sleep is on your backs while the worst position is sleeping on abdomen that can cause numbness, tingling and muscle pain, an expert says, according to ummid.com.

“People who feel groggy despite having a solid eight hours shut eye may benefit from changing their sleeping position. Those who lie on their backs are more likely to wake feeling rested due to the position reducing their risk of aches and pains, as well as heartburn”, sleep expert Professor Shelby Harris from the Albert Einstein College of Medicine in New York said.

“Despite this position’s benefits, only eight percent of people sleep facing up, with most opting to lie on their sides, which can worsen shoulder and hip pain, as well as causing acid reflux”, Professor Harris said. “Lying on your front, which only seven percent of people do, is the worst sleeping position due to it putting pressure on the entire body, which can cause numbness, tingling, and muscle and joint pain.”
