Admit it, there are times when you can’t help but feel sleepy after lunch. But is afternoon nap good for you, or does it do more harm than good? Studies show that napping does more than just reduce fatigue. It can elevate your mood and make it easier for you to learn and retain new information.
However, not all afternoon naps are equally beneficial. It turns out that what time you nap and how long that nap lasts make a difference. Having a perfect nap environment is also a factor. Tools like a white noise machine can help drown out disruptive noises so you can doze off quickly in no time.
Defining the Midday Slump: Why We Feel Sleepy After Lunch
Food is designed to give you energy, right? So why, after eating a large meal, are you feeling drowsy and a lack of motivation to, well, anything? For most individuals, having high-carb and high-fat meals, sugar-soaked desserts, and alcoholic beverages leads to a food coma.
The food coma, or the postprandial somnolence, is that sleepy, lethargic feeling as you undo your belt buckle a few notches after eating your meal. Why does this happen? Well, after you eat, the foods that are partially digested by the stomach acids make their way into the intestines. This is where the sleepiness begins. The nutrients from the food you eat trigger a chain reaction, calming down your sympathetic nervous system and kick-starting your parasympathetic nervous system. This leads to a “rest and digest” response, causing your body to feel very sleepy.
Individuals with postprandial somnolence may experience the following symptoms after eating:
- Drowsiness or sleepiness
- Low energy levels
- Lack of focus or concentration
The Benefits of the Perfect Power Nap (and Why 20 Minutes Is Magic)
A power nap is a short-term sleeping technique that can benefit your energy and wellness. Specifically, a 20-minute power nap may enhance your memory and boost your creativity.

Boosting Brainpower: How Napping Improves Memory and Focus

Memory performance can be significantly enhanced after napping. The sleep spindles during naps are periodic, burst-like signals between different brain areas, which are believed to reactivate and consolidate memories. Both the slow brain waves and the spindles increase plasticity, the brain’s ability to learn and adapt to new experiences.
- Power naps improve focus and concentration
A well-timed nap can improve your focus and ability to concentrate. It helps your brain to clean up sleep-inducing waste products that would otherwise inhibit brain activity, and it replenishes the brain’s energy stores.
The Dark Side of Dosing Off: When Naps Hurt Nighttime Sleep

If you have obstructive sleep apnea, you will not cure it with naps. However, you will find reliable relief in treating this; once treated, your daytime sleepiness should disappear.’
- Diabetic, or likely to develop diabetes
Recent studies have linked long afternoon naps to Type II Diabetes. A certain study found a curious link between long napping and a 45 percent increase in the incidence of diabetes when naps lasted at least 60 minutes.
- Don’t know what is causing your daytime fatigue
Other than sleep disorders, there’s a whole range of other causes for daytime sleepiness, including prescription medications and underlying health problems, to depression and mood disorders.
Timing Is Everything: Finding the Ideal Window for Your Afternoon Rest
Most sleep experts recommend napping before 2 p.m., so that your naps have less impact on your nighttime sleep.
Try not to nap after 4 p.m., as it might interrupt your sleeping schedule that night. Also, the later in the afternoon that you go to sleep, the more deeply you will fall asleep, making it harder to wake from it. In addition, drink a cup of coffee or a green tea right before you fall asleep to maximize performance after you wake up. It takes caffeine twenty minutes to kick in, and you will get an extra boost of energy when you wake up.
Nap Length Matters: Matching the Duration to Your Desired Benefit
Whenever you feel sleepy during the day, how many minutes should you power nap? Below are the different types of nap lengths and which one you should utilize for maximum productivity.
- 10 Minute Nap: The ten-minute nap is great for a quick energy boost and improved alertness. This nap is filled with NREM sleep, which makes it easier for you to continue on your day and not feel groggy when you wake up.
- 60 Minute Nap: A sixty-minute nap is suggested if you want to improve your memory for faces, names, and facts. This nap includes the deepest type of sleep, which is the slow-wave sleep. However, the downside of this nap is that you might feel groggy when you wake up because you were in a deep sleep, so it might take you some time to recover from it.
- 90 Minute Nap: In a ninety-minute nap, you undergo a full sleep cycle, which includes both the lighter and deeper sleep stages and REM sleep, which is where dreams occur. This sleep cycle improves emotional and procedural memory and creativity. Napping for ninety minutes also prevents sleep inertia.
