The Science of the Power Nap: Duration and Benefits
It is very common in India to take afternoon naps after school, and even for adults who stay at home, a midday nap is a must. Naps are brief periods of daytime sleep that typically last 10 minutes to a few hours. Mid-day naps lasting 10 to 30 minutes are referred to as power naps since they can instantly increase energy and alertness.
If you feel groggy even after taking a nap that is because you are taking a longer nap than required. Sleeping 2-3 hours during the day doesn’t make you feel any better, instead you will wake up feeling disoriented and groggy.
This is why it is recommended that you only take 10-30 minute naps throughout the day. Long naps produce more sleep inertia and deeper REM sleep (Rapid Eye Movement Sleep) which make it difficult to wake up in the middle of the sleep.

What is a Power Nap?
A power nap is a short sleep, usually between 10 to 30 minutes. It helps you feel more awake and energized without making you feel too tired or groggy. Power naps are great when you’re feeling sleepy but still need to do things during the day.
The trick is to nap for just a little while, so you wake up feeling better instead of more tired. If you sleep too long, you might wake up feeling extra sleepy. A power nap gives you a quick boost of energy, so you can keep going with your day.
How Long to Nap
A power nap lasting 20 to 30 minutes is usually considered ideal. It's long enough to provide all of the benefits of sleep without making you feel foggy when you get up.
If you sleep for more than 30 minutes, it will be difficult to get up because your brain has already begun to enter a deeper level of sleep; sleep inertia will drag you back to sleep, and you will wake up sluggish and disoriented.

Drawbacks of Long Naps
Most people in India take lengthier naps during the day, particularly in small cities where life moves slowly. When you wake up from a long nap, it takes some time for you to regain full alertness since you will feel sluggish and disoriented for a while.
Napping for 30 to 90 minutes boosts your chances of waking up in a deeper sleep state, causing sleep inertia. Sleep inertia can continue between 30 and 60 minutes after waking up, making it harder to wake up.
It is also found that those who nap for a longer time can suffer from high blood pressure and type 2 disease. Also, those who have insomnia or any other condition related to sleep should avoid taking naps.
