Do you ever wake up suddenly and feel so groggy you can’t make it out of bed? Well, that’s sleep inertia.
What scientists call sleep inertia is a state of fatigue and disorientation felt directly after being suddenly awaken. This happens usually happens to people who rely on alarm clocks to wake up, and don’t catch enough sleep the night before.
Since parts of your body (and brain) are still asleep, your cognitive performance isn’t what it should be. While it usually last for 15 to 30 minutes after waking up, it could last for hours in some people.

But be careful, because it having sleep inertia doesn’t exactly mean that you’re not getting enough sleep. It has more to do with sleep quality and at which point of your sleep cycle you awakened.
It is therefore important that you sleep in a room with no disturbance, such as sound, light or a ticking alarm clock. It is best to wake up naturally, at the end of a sleep cycle.
Although the symptoms only last for a short while and can be reversed with the help of coffee or
Splashing your face with cold water, sleep inertia can be dangerous in the long run.

It has been suggested that sleep inertia causes damage to your memory ability and overall productivity, and can also cause stress and put a strain on both your mind and body.
One way to beat sleep inertia is to take naps throughout the day. However, most people make the mistake of taking long naps, disrupting their sleep cycle and waking up with even more sleep inertia.
To avoid it after a nap, make sure to limit your naps to just under 30 minutes, because during the first 30 minutes of sleep your body enters a short sleep cycle which you can easily wake up from.
