1.If it takes you less than 5 minutes to fall asleep at night, you are sleep deprived. On average, it takes people between 10 and 15 minutes to fall asleep. If you are falling asleep faster than that it means you are overtired.

2. No one yet knows why we dream or what purpose dreams serve but there are several hypotheses. The theories claim we dream to help our memory, to sort through and store experiences, to “clean out” the unneeded information in our brains, among other things.

3. 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 this long.

4. 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 every now and again, but those suffering from Dysania find it particularly difficult. It is most likely to be a form of Chronic Fatigue Syndrome.

5. British researchers have developed a pair of glasses that can essentially reset a person’s body clock by projecting a ring of bright light that mimics the sunrise into the eye. The spectacles have been used with soldiers and can allow someone to go without sleep for as long as 36 hours, assumedly without experiencing functional deficits.

6. We need 7 to 8 hours of sleep per night. Sleep research has shown that the best time to fall asleep is between 10 PM and 11 PM. This way your hormones will be reset overnight automatically (diurnal hormone rhythm). Too much stress hormone (cortisol) counters the production of melatonin, the sleep hormone. When people get older, melatonin is not produced as well, but melatonin supplementation will fix this, re-establishing the balance between cortisol and melatonin

7. 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 considered to be perfectly healthy. However, they may be increased by anxiety, caffeine or physical activity close to bedtime. They are more common in young people and decrease as we get older.

8. People live very busy lives and often push the envelope by staying up late at night. This interferes with your growth hormone release that happens when you are deep asleep between midnight and 3 AM. If you miss this growth hormone spurt, you will have a hangover the following day and a lack of energy all day. If you ignore this and go until the early morning hours again the following day, you start interrupting your normal sleep cycle, get a fitful sleep and wake up several times during the night finding it difficult to fall asleep again.

9. Within 5 minutes of waking up, 50% of your dream is forgotten.

After an additional 5 minutes, 90% of recollection is gone. Sigmund Freud believed this was because dreams represent our repressed thoughts and so our brain wants to get rid of them quickly. However, it’s much more likely due to our brains simply being used much more as soon as we’re awake and so we forget much of what we’ve dreamed about.

10. A knocker-up was a profession that started during and lasted into the Industrial Revolution, a time when alarm clocks were neither cheap nor reliable. A knocker-up had to wake up sleeping people (by tapping their windows with long sticks until they woke up) so they could get to work on time.

11. Giraffes sleep only 1.9 hours daily for 5 to 10-minute session.

This is how Giraffe sleeps:

12. The light keeps the brain awake. So all the lights should be discarded while sleeping. The light of a laptop, phone, TV set etc. also cause sleep disturbances. So while sleeping electronic objects should be kept away. The house will be as dark as it would be to induce sleep.

13. The higher the altitude, the greater the sleep disturbance. Generally, sleep disturbance becomes greater at altitudes of 13,200 feet or more. The disturbance is thought to be caused by diminished oxygen levels and accompanying changes in respiration. Most people adjust to new altitudes in about two to three weeks.
