10 Reasons to go Back to Bed
Just in case you needed some extra motivation to stay in bed tomorrow morning, here is some psychological ammunition to go back into your warm bed:
Sleep deprivation is becoming increasingly problematic nationwide: In 2005, a poll conducted by the National Sleep Foundation concluded that Americans averaged just 6.9 hours of sleep per night. To many of us, that might not sound too shabby, but according to the report, that’s two hours less than people were sleeping on a nightly basis back in the 19th century; an hour drop per night compared to fifty years ago; and 15—25 minutes less per night since the turn of the century.
Lack of sleep can accumulate over the course of several days:  In one of the most extensive human sleep deprivation studies ever conducted, researchers at the University of Pennsylvania limited study volunteers to various levels of sleep deprivation for 14 consecutive days (for example, 6 hours in bed per night for two weeks straight). Their results showed that restricting sleep to six hours per night caused cognitive performance and reaction times so drop so dramatically, that by the end of the 2-week period, these test participants were performing as poorly as subjects who had forgone sleep for two nights in a row.
You’re a terrible judge of how tired you really are. (Sleep deprived participants) who were subjected to consecutive nights of decreased sleep were asked to rate their subjective feelings of sleepiness… and their self-assessments were total crap. At the end of the two week testing period, most volunteers believed themselves to be functioning relatively normally, even though their cognitive and physiological abilities were comparable to those of subjects who had gone days without sleeping at all.
If you don’t, you’ll die  Depending on who you ask, the world record for intentional sleep deprivation is somewhere between 11 and 19 days. That said, experiments in rats have shown that continuous sleep deprivation for upwards of two weeks inevitably leads to death; and outcomes are also fatal in rare cases where humans are literally unable to sleep. Such is the case with fatal familial insomnia (FFI). FFI is an exceedingly rare prion disease of the brain. Its progression is marked by a complete inability to sleep, dementia, and eventually death, with the typical survival span for FFI patients being between 7 and 36 months.
The dangers of microsleep. The American Academy of Sleep Medicine defines a microsleep as an episode, lasting anywhere between a fraction of a second to half a minute, during which external stimuli are not perceived. Have you ever driven through an intersection only to realize that you had no idea what color the traffic light was? There’s a chance you were experiencing a bout of microsleep.
Lack of sleep is expensive. The American Academy of Sleep Medicine reports that there are an average of 250,000 accidents every year related to sleep — which sounds high, until you read that as many as 80,000 drivers may be falling asleep behind the wheel every day. In 1994, a special report for the National Commission on Sleep Disorders Research found that all told, accidents related to sleep deprivation are estimated to have an annual economic impact in the range of $43 billion to $56 billion dollars.
Improve your sex life.  A 2009 study conducted by the National Sleep Foundation found that 75 percent of respondents reported symptoms of sleep problems — problems that carried over into many of the respondents’ sexual encounters (or lack thereof).  According to CBS, roughly one quarter of the respondents with partners reported that their sexual relationships had been hurt because they had “been too sleepy,” and that “they had sex less often or lost interest in having sex because they were too tired.”
It’s probably making you fat.  Evidence continues to pile up that prolonged periods of partial sleep loss may increase your risk of both obesity and diabetes via a number of different metabolic pathways, including your body’s ability to regulate glucose (i.e. the development of insulin resistance), and your brain’s ability to keep your hunger and appetite in check.
Sleep in, save your grade. In 1997, University of Minnesota researchers conducted a study on more than 7,000 high school students whose school district had recently switched from a 7:15 am start time to an 8:40 am start time. According to the APA: Compared with students whose schools maintained earlier start times, students with later starts reported getting more sleep on school nights, being less sleepy during the day, getting slightly higher grades and experiencing fewer depressive feelings and behaviors.
Because sleep deprivation is torture.  The use of sleep deprivation as a CIA interrogation technique has stirred up intense controversy in recent years, with many scientists — including James Horne, from the Loughborough University Sleep Research Centre — quick to characterize it as absolutely and unequivocally torturous.

10 Reasons to go Back to Bed

Just in case you needed some extra motivation to stay in bed tomorrow morning, here is some psychological ammunition to go back into your warm bed:

  1. Sleep deprivation is becoming increasingly problematic nationwide: In 2005, a poll conducted by the National Sleep Foundation concluded that Americans averaged just 6.9 hours of sleep per night. To many of us, that might not sound too shabby, but according to the report, that’s two hours less than people were sleeping on a nightly basis back in the 19th century; an hour drop per night compared to fifty years ago; and 15—25 minutes less per night since the turn of the century.
