Incredible Facts About Sleep

1. Sleep Deprivation and Appetite

People who don’t get enough sleep tend to eat more than people who get plenty of sleep. Lack of sleep causes the body to produce less leptin which is the hormone that regulates the appetite.

2. Snoring

Snoring is the number one cause of sporadic lack of sleep for around 90 million adults in the United States. About 37 million people in America commonly lose sleep due to snoring.

3. Late-shift Sleep Pattern Adjustment

The human body never actually adjusts its natural sleep pattern for those who work the late shift. Our bodies have a natural sleep pattern that’s determined by our biological clocks. No matter how long a person works the night shift, the body will always want to sleep at night and be awake during the day. There is even a sleep disorder classified as Shift Work Sleep Disorder. Symptoms include fatigue, insomnia,reduced performance, irritability, personal relationship difficulties and depressed mood.

4. Daylight Influence on Sleepiness

Daylight keeps us awake naturally. When daylight fades, the brain tells the body to produce more melatonin which makes us sleepy.

5.Jet Lag

Jet lag happens when people fly across time zones from one coast to the other. The body’s circadian rhythm, or internal clock, is set to the time zone it is used to. For instance, when someone lives in Florida then flies to California, his or her internal clock still thinks it’s 1:00 a.m. when it’s 10:00 p.m. in California. It commonly takes two or three days for circadian rhythms to make the adjustment.

6. Marital Status and Insomnia

People who are separated, widowed or divorced more commonly report that they are suffering from insomnia.

7. Exercise and Sleep

A regular exercise program contributes to healthy sleep habits. Falling asleep more quickly and sleeping more soundly can be attributed to regular exercise. On the other hand, irregular exercise makes it harder to fall asleep.

8. High-altitude Sleeping

The quality of sleep drops dramatically at high altitudes above 13,200 feet. Feelings of suffocation, unusually vivid dreams and not feeling rested upon waking are common side effects of sleeping at high altitudes. The problem is something called Periodic Breathing (PB) also known as Cheyne Stokes breathing. When PB occurs, the body breathes deeply for three to five breaths then takes two to three shallow breaths or no breaths for up to 15 seconds. The long pauses between breaths are known as apneas. It can take a few weeks after moving to a high-altitude location for the body to adjust.

9. Infant Sleep Habits

Infants who are put to bed when they are sleepy but awake tend to learn to fall asleep by themselves better than babies who aren’t put to bed until they are asleep. They learn to quiet themselves which means less bedtime effort for mom and dad and less frequent middle-of-the-night soothing.

10. New-baby Sleep Loss

Parents commonly lose 400 to 750 hours of sleep during the first year after a new baby is born.

11. Nap Requirements

Some children don’t need naps in the afternoon while others do. There are adults who need a mid-day rest, too. Their bodies actually require a short rest in the afternoon to be at their best. Most teenagers only nap during the afternoon because they stay up too late at night.

12. Napping at Work

According to a poll taken in 2008 by the National Sleep Foundation, 34 percent of employers allow their employees to take a nap during the work day. A napping area is even provided for workers by 16 percent of employers.

13. Melatonin

Melatonin supplements might help people fall asleep more quickly; however, it usually doesn’t help people stay asleep all night. Melatonin isn’t effective for everyone, though.

14. Elder Insomnia

As people age the incidence of insomnia increases. Part of this increase is simply due to aging but often the lack of sleep is connected to a health condition.

15. Falling Asleep too Quickly

If it takes less than five minutes for a person to fall asleep they are sleep deprived. The body should take 10 to 15 minutes to relax and fall asleep.

16. Sleeplessness Record

The longest any human has gone without sleeping is 18 days, 21 hours and 40 minutes. The record was set at a rocking chair marathon. The person who set the record experienced lapses in concentration, memory lapses, paranoia, slurred speech, hallucinations and blurry vision.

17. REM Sleep Facts

Rapid Eye Movement or REM sleep normally starts around 90 minutes after a person falls asleep. REM sleep happens for only brief periods of time throughout a person’s sleep cycle. Commonly, people only get a total of about 2 hours of REM sleep each night. Dreams during REM sleep phases usually have weird plots while dreams during non-REM sleep phases are less odd, more repetitive, have minimal imagery and are generally more like waking thoughts.

18. Sleeplessness Mimics Drunkenness

Going without sleep for 17 hours results in reduced performance capabilities similar to having a blood-alcohol level of 0.05%.

19. Tragedies Attributed to Lack of Sleep

The Challenger Space Shuttle accident in 1986, the Exxon Valdez oil spill in 1989 and the Chernobyl nuclear disaster in 1986 were all attributed to mistakes made due to sleep deprivation.

20. Noise and Sleep

Loud or unusual noises during the night may suppress the immune system, whether the noise wakes the person sleeping or not. This is especially true when the noise happens in the first two hours of sleep and last two hours of sleep.
