A nap is a short period of sleep throughout the day. One-third of all adults in the United States take a nap. Many people swear by naps as a great way to relax and refresh, while others find them to be ineffective and disturbing to their sleep. You may learn to take successful naps that support your body’s internal clock and keep your energy level during the day by knowing the importance of napping.
Health Benefits of Napping
Better Memory
Napping may help with memory consolidation (the process where our brain turns information into long-term memory). After learning something new, a decent nap appears to assist us to recall that information.
Researchers grouped 74 undergraduate students into groups in a modest 2019 study. They each spent 90 minutes studying different crab species. After that, one group dozed for an hour, another spent an hour learning (i.e. “cramming”), and the third group watched an hour-long movie. After that, they all had 90 minutes of crab school. Participants took a test on what they learned after a 30-minute pause, and then another one a week later. On the first test, the nap and “cram” group outperformed the movie group. On the second test, the nap team outperformed everyone.
Other studies have discovered that sleeping can aid perceptual learning (the ability to distinguish between diverse stimuli) and memory formation (recalling specific events or experiences).
Boost of Immunity
We all know how important our immune system is. Although you should continue to wash your hands and maintain physical distance, an afternoon nap may benefit your immune system. Sleep deprivation induces immunodeficiency by increasing the release of pro-inflammatory markers. By counteracting this by resting during the day for many days, the immunity and cellular function are improved.”
In a tiny 2015 research, for example, 12 men slept for barely 2 hours one night. The next day, they rested for 30 minutes before getting a full night’s sleep. The naps helped lower inflammatory cytokines and norepinephrine, a hormone that regulates immunity.
Improved Cognition
You will feel more awake after taking a nap. As a result, your brain should work more efficiently. A nap that includes REM sleep might also assist you in combining ideas in novel ways to come up with solutions. REM sleep engages regions of your brain related to images and dreams, and it usually begins 75 – 90 minutes after you fall asleep. Naps have also been shown to lower adenosine levels in the brain. Adenosine is a neurotransmitter that helps you sleep and helps you think.
How Long Should You Nap?
According to studies, a 20-minute nap is the most beneficial. This type of brief nap helps your mind and body to relax without going into deeper phases of sleep. If you have the time and desire for a longer nap, 60 to 90 minutes is sufficient to achieve deep, slow-wave sleep while remaining in the lighter phases of sleep, allowing you to wake up feeling aware. Medium-length naps of 45 minutes or less might be troublesome since you will most likely wake up throughout slow-wave sleep, the lowest stage, leaving you with a foggy sensation known as sleep inertia.
However, the benefits of napping can be felt with just a quick nap! Scientists discovered that persons who slept for 30 minutes or less had higher memory recall and general cognition than non-nappers as well as those who napped for longer periods of time. What is the duration of a power nap? When you’re experiencing a natural fall in energy and alertness, a 15- to 20-minute power nap in the early afternoon can replenish and refresh you. NASA conducted research on the benefits of power napping on astronauts and discovered that it provided a significant boost in performance and attentiveness.
How to Nap Correctly?
It is recommended that you nap between 1 and 3 p.m. for the greatest, most beneficial naps. Humans have a natural droop during these hours. If you try to nap earlier, your body will most likely not be ready for extra sleep, and if you nap later, it will likely interrupt your nighttime sleep. Make your surroundings as dark, chilly, and quiet as possible, since this will help you sleep better at night. If you’re having trouble sleeping, try using a sleep mask or a white noise generator. Instead of napping in your bed, you could decide to take a nap on a couch or in a comfortable recliner. You don’t want to become too comfy and sleep for too long, as this will make waking up harder.
Consider taking a “coffee nap,” in which you drink a cup of coffee before lying down. You’re revived from the nap when you wake up, and the caffeine kicks in, making for a really productive post-nap experience.
A huge number of studies clearly show that there are several benefits of napping. Putting aside a few minutes each day can benefit you in a variety of ways. Adding napping to your daily routine may require some effort at first, but after a few weeks, you will be able to determine the best sleeping time for you. After your snooze, you should feel well-rested and invigorated. However, if you wake up fatigued or sleepy, it may be time to reduce the length of your nap.
