The premise sounds almost too good to be true: taking a nap in the middle of the day could end up making you more productive. Of course, avid nappers will attest to feeling better after napping, but they’re naturally more likely to believe in the power of naps.
Similarly, people who have chosen not to nap — for fear that the downtime will eat into their working hours — will naturally be inclined to believe that naps are wastes of time.
So where does the truth lie?
Sleep and Productivity
It should come as no surprise that sleep and productivity are tightly interconnected. If you get the recommended amount of sleep each night (7 to 9 hours for most adults), you’ll be more alert, more focused, and equipped with a better memory.
Of course, one in three American adults aren’t getting the sleep they need to achieve peak productivity, and that rate is even higher in entrepreneurs, who often work long hours to reach their goals. Napping is shown to help mitigate the effects of sleep deprivation, and is therefore a helpful aid in restoring your productivity to optimal levels.
According to a study fueled by data from the American Time Use Survey, healthy sleep patterns are also correlated with productivity in the form of higher wages. Sleeping just one additional hour every week is correlated with an increase in short-term wages of about 1.5 percent, and long-term wages of about 4.9 percent. That’s a massive jump just for taking one extra hour-long nap a week.
The Evidence for Naps
Scientists still don’t have a firm grasp for exactly how naps function in relation to our sleeping habits, but there is some evidence that links naps, specifically, to working benefits. For example, one study by the University of Michigan randomly assigned 40 adult participants to two groups — one of which took a 60 minute nap, and the other of which watched a nature video — and found the following results present in the “napping” group:
· Less impulsive behavior. Napping participants were less likely to engage in impulsive behaviors, such as engaging with distractions or moving off-task.
· Higher tolerance for frustration. When trying to complete a difficult puzzle, napping participants were less likely to exhibit signs of frustration and other negative emotions.
· Improved focus and alertness. As expected, napping participants showed higher levels of focus and alertness.
The benefits of a 90-minute long nap are comparable to those of a full night’s sleep in some cases. Sleep is shown to be a facilitator of learning and long-term memory, and taking an extended nap midday can help you remember things you’ve recently learned. Also, taking an extended midday nap is shown to boost mood and alertness even more than a dose of caffeine.
The Downsides of Napping
Not all the evidence for naps is positive, however. If you aren’t careful about how you nap, you could end up with sleep inertia. This happens when you wake up at an inopportune time in your sleep cycles, so your body wakes up incompletely and unexpectedly. As a result, you feel groggy and drowsy, and more tired than you did before you took the nap in the first place.
There’s also some limited evidence that midday naps can be harmful for large-scale productivity. Spain, for example, is famous for its workday, which is centered around an extended midday break called a siesta.
This working schedule was recently the center of some controversy, as politicians noted Spaniards work more hours and are still less productive than workers in neighboring countries with a conventional 9 to 5 schedule. This evidence is limited, and was not formally studied.
How to Nap Effectively
Overall, naps can be a good thing for your productivity — and your health — but there are some precautions you’ll need to take to get the right benefits:
· Get the timing right. Napping after a long day of work when you only have 30 minutes of work left probably won’t help you. If you’re going to nap, make it a midday occasion to make the most of your post-nap energy boost.
· Set an alarm. If you sleep too long, you’ll experience sleep inertia. If you don’t sleep long enough, you won’t get the benefits of the nap. Aim for between 60 and 90 minutes of sleep time, but feel free to experiment — what works for you may be different than what works for others.
· Get quality sleep. If you’re going to sleep, sleep well. Find a comfortable, dimly lit area that won’t interrupt you with noise or distractions. Take off your shoes, clear your mind, and ask not to be disturbed.
You don’t need to nap every day to see an increase in productivity, nor does napping guarantee higher productivity. Try using napping as a tool to make up for sleep deprivation you may face on a regular basis, and strive for all-around healthier sleep habits.
When implemented consistently, napping can help you get more done every day — and you’ll feel better, too.
