Impaired spatial memory<\/li>\n<\/ul>\nSome people have a more severe form of sleep inertia, called \u201csleep drunkenness.\u201d With this type of sleep, inertia, confusion, slowness, and lack of coordination can last up to four hours.\u00a0<\/p>\n
While sleep inertia isn\u2019t a sleep disorder, sleep apnea and other conditions can make sleep inertia symptoms more severe. Likewise, sleep inertia can make the symptoms of other sleep disorders worse.<\/p>\n
There are multiple theories on the causes of sleep inertia<\/h2>\n
Scientists aren\u2019t sure exactly what causes that tired feeling from sleep inertia. But they have some ideas.<\/p>\n
High <\/strong>adenosine<\/strong> levels.<\/strong> Adenosine is a chemical in the brain that rises and falls during the day to help people feel sleepy and wake up. If the level of adenosine is too high in the morning, it encourages sleep.<\/p>\nInterruption of the <\/strong>REM sleep cycle.<\/strong> People go through multiple sleep cycles at night. They may feel groggy and disoriented if interrupted during a deep sleep period.<\/p>\nIncreased levels of delta waves<\/strong> in the brain. <\/strong>People with sleep inertia have higher levels of delta waves, which are linked to deep sleep.<\/p>\nReduced blood flow <\/strong>to the brain.<\/strong> During sleep, this can affect cognition.<\/p>\nThe prefrontal cortex. <\/strong>The decision-making parts of the brain, such as the prefrontal cortex, may reactivate or wake up more slowly than the rest of the body.<\/p>\nYour <\/strong>chronotype can be a factor.<\/strong> Your chronotype, which is your circadian preference for sleeping and waking (i.e., early riser versus night owl), can be a factor, as research suggests that night owls need more time to recover from sleep inertia than early risers.<\/p>\nWhen sleep inertia is a problem<\/h2>\n
Sleep inertia is primarily an inconvenience for some people as they fight the desire to roll over for a few more Zzz\u2019s.. But for others, sleep inertia can be dangerous. The diminished awareness can make people more susceptible to accidents.\u00a0<\/p>\n
This trouble concentrating is especially concerning for people who work late-night and third shifts, like factory workers or transportation drivers. It\u2019s additionally troubling for people who work in jobs that typically involve interrupted sleep cycles but need to make urgent decisions soon after waking, like medical professionals and emergency responders.<\/p>\n
Tackling sleep inertia<\/h2>\n
So what can people do to feel wide awake when they get up in the morning?<\/p>\n
Get enough sleep. <\/strong>This often starts with setting a schedule to go to bed and get up at the same time every day. Sleep inertia can be worse when you\u2019re sleep-deprived. Even if you slept eight hours last night, you might have a sleep deficit from previous days of missed rest.<\/p>\nTake a power nap<\/strong> during the day.<\/strong> But keep it short: 20 to 30 minutes, so you don\u2019t fall into a long, deep sleep.\u00a0<\/p>\nDrink caffeine<\/strong> to wake up in the morning and before a nap to help wake up after.<\/strong> Caffeine helps block the brain\u2019s adenosine receptors, keeping you more alert.<\/p>\nMake your room is comfortable for sleeping.<\/strong> Keep it cool and dark, and power down devices with distracting bright lights.<\/p>\nUse <\/strong>Fitbit\u2019s advanced sleep tools<\/strong>. <\/strong>\u00a0Wear your Fitbit while you sleep and let it work its magic. First, set a sleep goal, in addition to a consistent bedtime and wake-up targets. Then wear your Fitbit watch or tracker to record how long you sleep. You can analyze your patterns and adjust accordingly, all within the Fitbit app.<\/p>\nYou can also tap into your Sleep Score and the new Sleep Profile with Fitbit Premium to better understand your sleep habits. Learn more about how Fitbit can help you get a better night\u2019s rest here.\u00a0<\/p>\n
Exercise.<\/strong> <\/strong>Yoga or simple stretches increase the blood flow throughout the body, which helps you wake up.<\/p>\nEat an energy-rich breakfast<\/strong>.<\/strong> Eating a breakfast with proteins and complex carbohydrates will be satisfying and help sustain energy throughout the morning.<\/p>\nBuild in time to wake up from sleep inertia. <\/strong>Start your day slowly and recognize that even though you are awake, your brain may not be ready to do taxing work or make big decisions until later in the day.<\/p>\nChange your alarm to one that is more melodic.<\/strong> Researchers found that waking up suddenly to a beeping alarm can increase sleep inertia, interrupting the sleep cycle and creating stress. Instead, an alarm with a melodic tone or a favorite upbeat song makes a better transition from sleep to wakefulness.\u00a0<\/p>\nIf you sleep with your Fitbit device on, set a silent alarm to have your tracker or watch wake you up peacefully with a quiet vibration on your wrist. And with Smart Wake, you can set your Fitbit alarm to wake you during a lighter sleep stage so that you can wake up feeling more refreshed.\u00a0<\/p>\n
It may be impossible to avoid sleep inertia, but you also don\u2019t have to accept it passively. If you don\u2019t have time to snuggle under the covers and sleep in, understanding what causes sleep inertia and having tips to counter it will give you the energy to wake up fully so you can start your day successfully.<\/p>\n
