The facts about sleep

**Most of what we know about sleep has only been discovered in the last 25 years, but it’s fair to say we’ve made up for it. Scientists and researchers all over the globe are learning more and more about sleep every day, teaching us things we never even dreamed about (excuse the pun).I have put the most interesting and surprising facts about sleep that you may not know.** The facts about sleep: **1. 12% of people dream entirely in black and white** Before colour television was introduced, only 15% of people dreamt in colour. Older people dream in black and white more often than younger people, it’s all here in **this study.** **2. Two thirds of a cat’s life is spent asleep** This will come as no surprise to most cat owners. Every sofa is a sofa bed to them. Otherwise found on your favourite seat or a computer keyboard.

**3. A giraffe only needs 1.9 hours of sleep a day, whereas a brown bat needs 19.9 hours a day** Learn more about other animals and their sleep **here** including ferrets, cheetahs, and sloths. **4. Humans spend 1/3 of their life sleeping** This obviously differs depending on the age of the human, but on average it’s around a third, which is quite a lot when you think about it. **5. The record for the longest period without sleep is 11 days** This was set by a Californian student named Randy Gardner in 1964. This is definitely not recommended, however, as Randy experienced extreme sleep deprivation and others have died staying awake for too long. **6. It’s not uncommon for deaf people to use sign language in their sleep** There are many instances where people have reported their deaf partners or children using sign language in their sleep. **7. Dysania is the state of finding it hard to get out of bed in the morning** We’ve all no doubt found it tricky getting out of bed before, but those suffering from Dysania find it particularly difficult. It’s most likely to be a form of Chronic Fatigue syndrome.

**8. Parasomnia is a term that refers to unnatural movements during your sleep** Some people have even committed crime due to parasomnia, including sleep driving and even murder. **9. The sensation of falling when half asleep and jerking yourself awake is called ‘hypnic jerks’** No one is totally sure why hypnic jerks occur but they are deemed to be perfectly healthy. However, they may be increased by anxiety, caffeine or physical activity close to bedtime. They’re more frequent in young people and decrease as we get older. **10. It’s thought that up to 15% of the population are sleepwalkers** This is according to the **national sleep foundation.** It’s also a myth that you shouldn’t wake someone who is sleepwalking. **11.Sleep deprivation will kill you more quickly than food deprivation** Neither are good for you, obviously, but **this article** claims that sleep is actually more important than food in the short term.

**12. Those born blind experience dreams involving things such as emotion, sound and smell rather than sight** This is a topic that is really quite interesting and the timing of the blindness in a person’s life may impact what that person dreams about. **That's all the facts about sleep i have put together and i think it’s interesting that's why i share with everyone..** If you enjoy this article then give valuable comments and Don't forget to subscribe if you want to read my article more..
