10 Fun and Useful Facts about Sleep

Sleep. It’s as essential as eating and breathing, yet we struggle to make time for it given our over-packed schedules.

We’re constantly under pressure to fit more in, and with the online world at our fingertips 24/7, it’s becoming harder to justify a solid, 8 hour block of sleep. Time and time again, we’ve been warned that sleep deprivation can have a disastrous effect on our health, but when balancing the role of student with, say, the role of employee, mother, father, friend and pet-owner, now might be the time to start giving some thought to your sleeping habits.

We hope that our list equips you with some fun and useful new information about sleep – but if we find out that you’re using your sleeping time to read this, we will look for you, we will find you, and we will tuck you in really, really tight.

  • OneThe only mammal that deliberately puts off sleeping is the human. In our defense, it’s not like cats have a whole season of Suits to catch up on.cat-coffeeImage Credit:  www.flickr.comphotoswheatfields1824789454
  • TwoFalling asleep should ideally take 10 to 15 minutes, so if you’re able to fall asleep at night in less than 5 minutes, it’s likely that you’re sleep deprived.
  • ThreeThere are two times during a 24-hour period that you experience a peak in tiredness- 2am and 2pm. So perhaps your post-lunch food baby isn’t the only thing to blame for your heavy eyelids.
  • FourPeople who sleep less, eat more. This is because of decreased levels of the hormone ‘leptin’, which regulates the appetite, and helps well-rested people control their cravings for food.dessert-cake
  • FiveLevels of light play a big part in establishing sleeping rhythms, as darkness encourages the body to fall asleep and light encourages the body to wake up. The light emitted from devices like your TV, computer, phone or even alarm clock will trigger a drop in the levels of a brain chemical that promotes sleep. Blind people often have trouble with their sleeping rhythms because of their inability to perceive light.
  • SixIn order to sleep, you need to cool down. That’s why it can be hard to sleep on hot nights, or if you’ve exercised too close to bedtime. We need to hit a certain body temperature in order to sleep soundly, and as we age, this optimum body temperature reduces, making it more difficult for older people to sleep well.
  • SevenThe “natural alarm clock” is not some sort of myth or magical power, it’s actually a burst of a certain stress hormone. It is said that people can anticipate the stress of waking up on a subconscious level.alarm-clock
  • EightOver the course of your life, it’s likely that you’ve taken a nap of 3-30 seconds without even realising it. These are generally referred to as ‘microsleeps’, and often, they take place while your eyes are open.
  • NineAlcohol is far more potent when consumed by a sleep-deprived person. After 5 days of even partial sleep deprivation, 3 drinks does to your body what 6 drinks does to a well-rested person. On another alcohol-related note- if you stay awake for 17 consecutive hours, your performance will drop to the level of a person with a blood alcohol level of 0.05%
  • TenThe longest period recorded without sleep is 18 days, 21 hours and 40 minutes. This record was set during a rocking chair marathon and caused the record holder to experience hallucinations, paranoia, slurred speech, blurred vision and lapses in concentration and memory. This record is no longer published in new editions of the Guinness Book of World Records, as the promotion of extreme sleep deprivation is considered unethical. Fair call!
