Why do I feel bad when I wake up from a nap?
Why do I feel worse after taking a nap? That familiar groggy feeling is called “sleep inertia,” and it means that your brain wants to keep sleeping and complete a full sleep cycle. This is why experts recommend keeping naps to just 10 to 20 minutes, among other nap best practices.
How long does it take to fully wake up from a nap?
Now, the good news. Typically, sleep inertia disappears after about 30 minutes, according to a 2019 analysis. In fact, it can sometimes disappear within 15 minutes. However, what some scientists call a “full recovery” takes about an hour to achieve — and it can continue to improve over the course of about 2 hours.
Is it bad to take a nap in the morning?
The best times to take a nap are early in the morning, in the middle of the afternoon, and during the night. Also, anytime you feel very sleepy but need to stay awake, a short nap can often restore alertness. People are less able to nap late in the morning and early in the evening.
What does it mean when you wake up sleepy?
Chances are, your morning grogginess is just sleep inertia, which is a normal part of the waking process. Your brain typically doesn’t instantly wake up after sleeping. It transitions gradually to a wakeful state. During this transition period, you may feel groggy or disoriented. 7 дней назад
Are 2 hour naps bad?
A: Naps are OK. But you’ll probably want to nap for less than an hour, and you’ll probably want to nap earlier in the day, like before 2 p.m. or 3 p.m. If you can power-nap for 15 or 20 minutes, so much the better. Napping for an hour or longer increases your risk of falling into the deep stages of sleep.
Is napping a sign of bad health?
In a recent study, researchers say napping two or three times a week might be good for your heart health. Experts say daily napping may be a sign of inadequate nighttime sleep or an underlying health problem. One expert says naps should be shorter than 30 minutes or longer than 90 minutes.
Is a 45 minute nap good?
A nap of 60 minutes improves alertness for up to 10 hours. Research on pilots shows that a 26-minute “Nasa” nap in flight (while the plane is manned by a copilot) enhanced performance by 34% and overall alertness by 54%. One Harvard study published last year showed that a 45–minute nap improves learning and memory.
What sleep inertia feels like?
“Sleep inertia” refers to the transitional state between sleep and wake, marked by impaired performance, reduced vigilance, and a desire to return to sleep. The intensity and duration of sleep inertia vary based on situational factors, but its effects may last minutes to several hours.
Is a 30 minute nap good?
On the other hand, sleeping for 30 minutes or longer gives the body enough time to enter deep (slow-wave) sleep. However, napping for too long or waking up from slow-wave sleep can leave you feeling groggy for up to an hour. This period of drowsiness is also called “sleep inertia.”
Is 90 minutes a good nap?
McGinn adds 10- to 20-minute naps can boost energy and alertness, without the feeling of sleep inertia, while a 90-minute nap boosts memory and creativity, which is ideal if you are studying for a test. “Short naps generally don’t affect nighttime sleep quality for most people,” she continues.
Is a 5 hour nap bad?
I write about the brain and the body but sometimes other things. Scientists find that drifting off for more than one hour could be risky. Napping for longer than an hour is linked to higher risk of heart disease and death, according to a new study.

Napping isn’t sleeping
The reason I was wrong is, napping is not sleeping. To get the benefit of a refreshing power nap, you don’t need to fall asleep. It’s enough to relax yourself and let your thoughts drift off, even while remaining mostly awake.

In extreme cases, a person with hypersomnia might sleep soundly at night for 12 hours or more, but still feel the need to nap during the day. Sleeping and napping may not help, and the mind may remain foggy with drowsiness.
What are the 3 types of fatigue?
There are three types of fatigue: transient, cumulative, and circadian:
- Transient fatigue is acute fatigue brought on by extreme sleep restriction or extended hours awake within 1 or 2 days.
- Cumulative fatigue is fatigue brought on by repeated mild sleep restriction or extended hours awake across a series of days.
Why the more I sleep the more tired I am?
It’s hardest to wake up from sleep cycles three and four. If you sleep more than you need to you’re probably going to wake up from a later sleep cycle, meaning you’ll feel groggy and tired even though you’ve slept more.
