Power Napping for Increased Productivity, Stress Management and Health
The Benefit of a Power Nap: Studies show that 20 minutes of sleep in the afternoon provides more rest than 20 minutes more sleep in the morning (though the last two hours of morning sleep have special benefits of their own). The body seems to be designed for this, as most people’s bodies naturally become more tired in the afternoon, about 8 hours after we wake up.
How Long Should I Sleep?
Many experts advise to keep the nap between 15 and 30 minutes, as sleeping longer gets you into deeper stages of sleep, from which it’s more difficult to awaken. However, research has shown that a 1-hour nap has many more restorative effects than a 30-minute nap, including a much greater improvement in cognitive functioning. The key to taking a longer nap is to get a sense of how long your sleep cycles are, and try to awaken at the end of a sleep cycle. (It’s actually more the interruption of the sleep cycle that makes you groggy, rather than the deeper states of sleep.)
As there are pros and cons to each length of sleep, you may want to let your schedule decide: if you only have 15 minutes to spare, take them! But if you could work in an hour nap, you may do well to complete a whole sleep cycle, even if it means less sleep at night. If you only have 5 minutes to spare, just close your eyes; even a brief rest has the benefit of reducing stress and helping you relax a little, which can give you more energy to complete the tasks of your day.
