Nothing is worse than waking up in the morning feeling out of it and sleepy when you thought you got a decent night's rest. If you logged in enough hours, you should feel well rested, right? Unfortunately, there are a number of reasons you feel groggy in the morning, some of which you may not even be aware of. Your quality of sleep matters just as much as your quantity, and some of your nighttime habits may be setting you up for a lethargic morning.
"People feel groggy in the morning essentially because they are sleep deprived," Dr. David Weissman, M.D., a primary care physician who sees patients via telehealth app LiveHealth Online, tells Bustle. "More specifically, grogginess, or what doctors call sleep inertia, is the feeling of incomplete awakening due to sudden awakening during REM sleep. REM stands for rapid eye movement, and is one of four stages of sleep and is the one associated with dreaming. If you are suddenly woken up in the middle of REM sleep, it leads to sleep inertia which can last from 15 minutes to about four hours. During this groggy period of sleep inertia, you have a reduced capacity for doing even simple activities."
Making sure you get enough good quality sleep, as well as avoiding waking up in the middle of your REM cycle, can help get rid of that morning fog. Here are seven surprising reasons you might feel groggy in the morning, according to experts.
