If you sleep through the night but still feel tired, you could have a chronic sleep issue, one that’s keeping you from getting a restful night’s sleep. So, here are the signs to look for:

  • #1: Morning mouth. Waking up with a bad taste in your mouth could mean that acid reflux is disturbing your slumber, where acid backs up into your esophagus and causes heartburn. The fix? Don’t eat within 2 hours of bedtime. And try sleeping on your left side, because stomach acid has a harder time getting up into your esophagus and staying there when you’re in that position.

  • Another sign of a sleep problem: Your jaw clicks, pops, or feels sore - those are symptoms of bruxism, also known as teeth grinding. Since grinding tenses your jaw muscles, you never relax enough for deep sleep. And only 5% of teeth-grinders know they do it. So, ask your dentist to check for signs of wear on your teeth. If bruxism’s an issue, they can prescribe a mouth guard that will help your jaw relax.

  • Finally: If you always feel groggy in the morning you’re probably out of sync with your circadian rhythms. Working a shift schedule, watching TV in bed, or even using a nightlight can throw off your hormones to the point that you get a second wind when you should be going to bed. Luckily, there’s an easy fix. Just take a walk every morning. Getting a dose of morning light, even if it’s cloudy, will help reset your internal clock. That way your sleep and wake hormones function properly, and you’ll feel tired at the right time at night, and sleep more soundly when you go to bed.
