Sleep - it's something many of us both love to get and sometimes have too much of. Whether your favourite place to rest is on your favourite bed, like one of our grey upholstered ottoman beds, on a sofa bed or even on your favourite chair in the living room, sleep is something we can all relate with. Read on for some interesting facts about sleep that you may not have heard of!
According to the national library of medicine, Only 15% of people dreamed in colour before colour television was introduced. Black and white dreams are more common in older people's dreams than in younger people's dreams.
This certainly varies depending on the human's age, but on average, it's roughly a third, which is a significant amount.
Randy Gardner, a Californian student, achieved the record in 1964. This is not encouraged, as Randy suffered from severe sleep deprivation and others have died as a result of staying awake too long.
We've all struggled to get out of bed at some point, but Dysania makes it considerably more difficult. The most likely diagnosis is CFS (Chronic Fatigue Syndrome).
According to the National Sleep Foundation, this is true. The idea that you shouldn't wake someone who is sleepwalking is likewise a misconception.
After another 5 minutes, 90% of remembrance has vanished. This, according to Sigmund Freud, is because dreams represent our suppressed thoughts, and our brain wants to get rid of them as soon as possible. However, it's much more likely that as soon as we wake up, our brains are put to work, and we forget a lot of what we've dreamed about.
We used to believe that when we sleep, everything switches off. However, scientists have learned that our brains are quite busy while we sleep in the previous 60 years. In fact, while sleeping, several areas of the brain consume more oxygen and glucose than when awake.
Sleep occurs in 90-minute cycles throughout the night. Every cycle includes REM (dreaming) sleep, even if it is only for a few minutes. We also have numerous brief arousals during the night. Most of these arousals go unnoticed, and most dreams are forgotten.
Why we need so much sleep is still a mystery to scientists. They believe it heals our bodies and aids in the organisation of our minds. We do know that without it, we wouldn't be able to function correctly.
The deepest stages of sleep occur during the first three hours of sleep (Slow Wave Sleep). We have more of the sleep stage later in the night, with vivid dreams (Rapid Eye Movement Sleep, REM sleep).
