5 Reasons Why Sleeping In Every Day Will Boost your Productivity

1) Depending on your chronotype, you may be a Night Owl living in a Morning Lark’s world
Morning Lark: Morning person, naturally wakes up 2 hours earlier than the majority of the population, is ready for sleep between 8pm - 10pm. Cope more easily with early shifts.
Night Owl: Night person, naturally wakes up 2 hours later than the majority of the population, doesn’t feel sleepy until 12am - 2am. Cope more easily with late shifts.
Many creative types, such as writers, actors, and computer programmers, tend to be Night Owls. If they don’t have to get up early for work, many Night Owls choose to go along with there inherent sleep schedule and work until very late at night.
2) Most people need more than 8 hours of sleep
Before the invention of the electric light in 1879, most people slept 10 hours each night, and this has recently been discovered as the ideal amount of sleep for optimum performance. Additionally, people in cultures that are free from the demands of modern society typically sleep 10 hours each night. There are big benefits to sleeping ten hours per night:
Research Center of the Henry Ford Hospital in Detroit, Michigan, have demonstrated that alertness significantly increases when eight-hour sleepers who claim to be well rested get an additional two hours of sleep. Energy, vigilance, and the ability to effectively process information are all enhanced, as are critical thinking skills and creativity.

3) Sleep consistency is important; the time you wake up is not (unless you must get up for work)
Sleep consistency is key- this is why I named this post “5 Reasons Why Sleeping In Every Day Will Boost your Productivity”. But the time you wake up is not important:
In 1757 Benjamin Franklin gave us the epigram “early to bed, early to rise makes a man healthy, wealthy and wise.” It would be more accurate to say “Consistently to bed and consistently to rise….” As long as you fulfill your sleep requirement without interruption, it doesn’t really matter what time you go to bed or get up.

4) Sleeping in can improve your long-term memory retention, memory organization, and learning
REM Sleep: Stage of sleep with predominant eye movements and dreaming. During REM, brain neuronal pathways are fired randomly, and REM sleep causes strengthening of memory circuits similar to lifting weights causes strengthening of muscles.
When you fall asleep at night, you go through 4 stages of sleep every 90 to 110 minutes. You typically go through 4-5 cycles of these stages each night. With each successive cycle, more time is spent in REM stage. During later sleep cycles, REM sleep increases from twenty to as much as sixty minutes.
Whenever you have a short night of sleep, you eliminate the long REM periods that come toward morning. This can have significant negative consequences in terms of your learning, thinking, memory, and performance. The only solution is for you to get more sleep.
5) Sleeping in allows you to catch up on sleep debt
Sleeping is a way for you to catch up on sleep debt (Hours of sleep you need per night - Hours of sleep you actually get). In my sleep debt post, I recommend that instead of sleeping in, you catch up on sleep debt by going to bed earlier. However, if you can’t get to bed early, and can’t get enough sleep in your normal schedule, it’s smart to sleep in to catch up on sleep debt when you are able to.
