Question: what side do you sleep on when you have a stuffy nose?
Answer: Sleeping on your back is your best option when you've got the sniffles, says Lina Velikova, MD, at Disturb Me Not. "Lying on the side might make one or both nostrils completely congested." The goal is to allow your mucus to run down and out overnight, instead of clogging up your airways and sinuses.
