25 Cool Facts About Sleep You Probably Didn't Know

Показать описание

Sleep plays a vital role in good health and well-being throughout your life. During sleep, your body is working to support healthy brain functioning and maintain your physical health. The damage from sleep deprivation might not hurt you instantly but it’s a safe bet it will harm you over time if it continues for a long time. For example, ongoing sleep deprivation can raise your risk for chronic health problems such as depression, high blood pressure, obesity, diabetes, and various heart problems. The ancient Greeks were the first people to realize the importance of sleep in people’s lives and for that reason they worshiped Morpheus (god of sleep and dreams), to whom they prayed for a good night’s sleep and peaceful dreams. Today, however, since the rhythms of modern life are more demanding and stressful than ever before, many people tend to suffer from insomnia (mainly due to stress and anxiety) or intentional sleep deprivation in an attempt to achieve more than a normal human being should in a day. In case you’re one of those people who don’t fully realize the importance of sleep, take a look at these 25 Cool Facts About Sleep You Probably Didn't Know and we can promise you that you will make a few changes in your life starting today.

A new baby typically results in 400–750 hours of lost sleep for parents in the first year.

In the REM (rapid-eye movement) stage of sleep (it’s when we are dreaming) your body is normally paralyzed. In rare cases, however, people act out their dreams. This has led to broken arms and legs, broken furniture, and in at least one reported case, a house burning down.

Dreams are responsible for many of the greatest inventions of mankind. A few examples include the idea for Google, the alternating current generator, DNA’s double-helix form, and the sewing machine, among others.

It might sound like something out of Inception, but it’s true. Falling backward while in a dream is a popular technique for waking from an unpleasant dream, or changing the scenery of your unpleasant dream. And keep in mind that, just as in Inception, falling backward in a dream can sometimes cause a “false awakening,” where you think you’re awake but still dreaming.

Regardless of whether men spend more of their waking hours thinking about sex, a 2007 study found that they are no more likely to dream about sex than women. However, the type of sex dreams that participants had varied by gender. Women are more likely to dream about sex with celebrities, exes, and current partners. Men are more likely to dream about having multiple partners, and ninety percent of men’s sex dreams involve women initiating sex.

In rare cases, people can die from insomnia. To be more specific, fatal familial insomnia is a rare genetic disease that prevents a person from falling asleep, eventually leading to death. The average survival span for patients diagnosed with FFI after the onset of symptoms is eighteen months. This very rare disease has been found in just twenty-nine families worldwide, affecting a total of seventy-eight people, and the first recorded case was an Italian man, who died in Venice in 1765.

Women are two times more likely to have insomnia than men, according to the National Sleep Foundation. Experts speculate that the reason may have to do with female hormones. Sleepless nights and daytime sleepiness have been linked to hormonal changes in a woman’s life, including pregnancy, menopause, and the menstrual cycle.

People who don’t get enough sleep are more likely to have bigger appetites due to the fact that their leptin levels (leptin is an appetite-regulating hormone) fall, promoting appetite increase. This explains why people who suffer from insomnia usually gain weight.

Scientists still don’t know—and probably never will—if animals dream during REM sleep, as humans do.

According to the International Classification of Sleep Disorders, shift workers are at increased risk for a variety of chronic illnesses such as cardiovascular and gastrointestinal diseases. In other words, and despite what your boss might tell you, the body never adjusts to shift work.

Fact 26... We spend almost 30% of our lives sleeping, that's a lot of life wasted when you think about it. If I had the choice, I'd rather go skydiving then sleep, sleep is too boring.

you get energy from sleep and you can also feel energized

I laughed during some of the video because for some reason I dream in both color and black and white, I remember most of my dreams even from my childhood, I have dreams about people I have yet to meet, I have dreams of the future, I have both sleep insomnia and disania. I have once fallen asleep for three days straight without even peeping open an eye and I can stay away for days on end. Yet when I stay awake for two days I don't feel drunk at all I feel like I have a hangover that's all

If I'm dreaming & I want to wake up, I tilt my head hard right to wake up. If I'm awake and something bad happens, I've tilt my head to try & see if I'm dreaming. If I'm stuck in sleep paralysis I move my Big to and pull myself up out of it( feels like I'm under deep water, very hard to wake up)

I was kind of phasing out, so the record scratch at 1:00 scared the shit out of me.

Hey, What software do you use to edit this? Like how do you add that little 25 in the corner over your video or the small box with a video within your own. I really want to get into video making but can't find any good tutorials for what im looking for. Can someone help me out?

Sometimes I wake up and I don't remember sleeping and I remember staying awake in my bed. I can't tell if realistic dream, sleep paralysis, or awake.

I think I have "dissania" (however you spell it), I have a tough time getting up from my bed unless i'm motivated to do something asap. I mean it's either that or my bed is just too damn comfortable.
