Falling asleep fast may seem like a good thing, but according to Alex Savy, a certified sleep science coach and founder of SleepingOcean, if you’re able to knock out in less than five minutes, that’s cause for concern. In fact, it’s one of the most common signs of sleep deprivation. “If you fall asleep fast, it might mean that you aren’t getting enough sleep overall,” he explains. Sujay Kansagra, MD, a sleep health expert for Mattress Firm and director of Duke University’s Pediatric Neurology Sleep Medicine Program, says other signs of sleep deprivation include moodiness, over-emotional response, impaired attention and decision making, and high blood pressure. “When chronic sleep deprivation continues, the body must work harder to maintain everyday functioning, and one of the most affected organs is the heart,” he explains. “Sleep deprivation can cause elevated blood pressure, and when exacerbated, continued sustained high blood pressure can even lead to stroke.” And for more health problems you should be aware of, If This Body Part Hurts You at Night, See Your Doctor.

And do not hesitate to talk to your doctor to get a proper diagnosis.” And for more on your sleep, beware that Going to Bed Past This Exact Time Is Hurting Your Health, Study Says. Leigha Saunders, ND, a naturopathic doctor and sleep expert, says it should ideally take you anywhere from five to 20 minutes to fall asleep. “If it takes you longer than this, you’re probably aware of the fact that you’re trying to fall asleep,” she says. “This can generate thoughts like ‘Why is it taking me so long to fall asleep?’ or ‘Why haven’t I fallen asleep yet?’ If you’re conscious of those thoughts, it’s a sign it’s taking you too long.” And for more health tips delivered straight to your inbox, sign up for our daily newsletter.ae0fcc31ae342fd3a1346ebb1f342fcb Falling asleep in less than five minutes isn’t the only sign of a sleep disorder.
