As you all know or should know that getting enough sleep is vital for your health and productivity etc etc etc, but have you ever noticed the difference between when you sleep after lunch and when you don't sleep?
Oh and by the way..this is a hammock

Why A Power Nap? Facts on Sleep:
While small children typically take naps in the afternoon, our culture generally frowns upon mid-day sleep; however, even in those who get enough sleep (but particularly in those who don't), many people experience a natural increase in drowsiness in the afternoon, about 8 hours after waking. And research shows that you can make yourself more alert reduce stress and improve cognitive functioning with a nap. Mid-day sleep, or a 'power nap', means more patience, less stress, better reaction time, increased learning, more efficiency and better health.
Here's what you need to know about the benefits of sleep and how a power nap can help you!
How Much Sleep Do You Need? The body needs 7-8 hours of sleep per day; 6 hours or less triples your risk of a car accident. (Interestingly, too much sleep--more than 9 hours--can actuallybe harmful for your health; recent studies show that those who sleep more than 9 hours per day don't live as long as their 8-hour-sleep counterparts!)
The Effects of Missed Sleep:
Sleep is cumulative; if you lose sleep one day, you feel it the next. If you miss adequate sleep several days in a row, you build up a 'sleep deficit', which impairs the following:
- Reaction time
- Information processing
- Short-term memory
How Long Should I Sleep? When you sleep you pass through different stages of sleep, known together as a sleep cycle. These stages include light sleep, deep sleep (which is believed to be the stage in which the body repairs itself), and rapid-eye movement sleep, or REM sleep (during which the mind is repaired).
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. Also, longer naps can make it more difficult to fall asleep at night, especially if your sleep deficit is relatively small. 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.
Tips For a More Effective Nap If you want to obtain more sleep, and the health benefits that go with getting enough sleep, here are some tips for more effective napping and sleep at night:
- Avoid caffeine after 3pm. It's a stimulant that can disrupt your sleep and stay in your system longer than you think; its half-life is four to six hours!
- If you don't want to nap a long time, set an alarm.
- If you don't have time for a power nap, or don't feel comfortable napping during the day, try meditation ; it gives your body a rest and produces slower brain waves similar to sleep.
Napping has been found to be beneficial. Napping for 20 minutes can help refresh the mind, improve overall alertness, boost mood and increase productivity. Napping may benefit the heart. In a six-year study of Greek adults, researchers found that men who took naps at least three times a week had a 37 percent lower risk of heart-related death.
Scientists have been investigating the benefits of napping for years: the 20-minute nap, as well as sleep durations of 1–2 hours. Performance across a wide range of cognitive processes have been tested. Studies demonstrate that naps are as good as a night of sleep for some types of memory tasks. A NASA study led by David F. Dinges, professor at the University of Pennsylvania School of Medicine, found that naps can improve certain memory functions and that long naps are better than short ones. In that NASA study, volunteers spent several days living on one of 18 different sleep schedules, all in a laboratory setting. To measure the effectiveness of the naps, tests probing memory, alertness, response time, and other cognitive skills were used.
The National Institute of Mental Health funded a team of doctors, led by Alan Hobson, Robert Stickgold, and colleagues at Harvard University for a study which showed that a midday snooze reverses information overload. Reporting in Nature Neuroscience, Sara Mednick, Stickgold and colleagues also demonstrated that, in some cases, a 1-hour nap could even boost performance to an individual's top levels. The NIMH team wrote: "The bottom line is: we should stop feeling guilty about taking that 'power nap' at work."
