We spend a third of our lives doing it. From the moment we are born until the ultimate sleep. Thomas Edison claimed that it was a waste of time, and others like Florence Nightingale and Margaret Thatcher got by on only four hrs of sleep a night.
5. How Much Sleep Is Required?
Sleep can vary from person to person. Whilst, Margaret Thatcher, stated above, can get by on four hours sleep per night, most healthy adults need between 7 to 9 hrs sleep to function at their best. The hours vary slightly with different age groups.
Here’s a chart for the recommended hours of sleep for each age group:
- Newborn (0 – 3 months) – 14 – 17hrs sleep
- Infact (4 – 11 months) – 12 – 15hrs sleep
- Toddler (1 – 2 years) – 11 – 14hrs sleep
- Pre-school (3 – 5 years) – 10 – 13hrs sleep
- Teen (14 – 17 years) – 8 – 10hrs sleep
- Young Adult (18 – 25 years) – 7 – 9hrs sleep
- Adult (26 – 64 years) – 7 – 9hrs sleep
- Older Adults (65+) – 7 – 8hrs sleep
Here at Snoreeze we believe that you have the right to sleep at night. That is why we are championing a good night’s sleep with our 8 Hour Challenge. Snoreeze is challenging snorers and their partners across Great Britain to get their 8 hours of sleep every night. Taking part is a simple as 1, 2, 3!
4. The Future Of Sleepwalking
When you hear stories of sleepwalkers, you just imagine people walking around the house, but sleepwalkers can do other things. Our night-time activities have evolved with our daytime ones. There have been cases where people have sleep-texted or sent a sleep-email.
Professors have stated that the act of texting and answering an alert on our phones have become so ingrained in us that it’s crossing boundaries between sleeping and being awake. There are a few simple tricks to prevent any embarrassing messages being sent whilst you snooze: turn off your phone at night and keep it well out of reach.
3. Earliest Theories About Sleep
The history of sleep and dreaming goes back to the BC era. Early scientists, physicians, and psychologists had a hard time trying to figure out why we sleep.
One of the first thoughts on why we sleep was by Alcmaeon, one of the most renowned natural philosophers and medical theorists of his time (Ancient Greece). His theory stated that sleep occurs when blood vessels in the brain are filled up and we wake up when the blood vessels empty… He also thought that the eye contains both fire and water. Kudos for trying, Al! The rest of the scientific community would ignore the science of sleep for another 2,000 years, becoming one of the most under-researched areas of human behaviour.
In ancient Egypt, sleep was something that people had no control over. The Egyptians believed that when they fell asleep, they entered a place between the lands of the living and the dead. Sleep was thought to be the works of spirits and a way for the dead to communicate with the living.
2. Longest Amount Of Time Without Sleep
A Californian man named Randy Gardner holds the record for the longest period of time a human has gone without sleep. Gardner managed to stay awake for 11 whole days and 24 minutes (that’s 264.4hrs).
Gardner’s health was monitored by Lt. Cmdr. John J. Ross, and he reported that Gardner’s behaviour changed dramatically. Lack of sleep caused Gardner problems with his concentration and even short term memory loss. On the eleventh day, when asked to subtract 7, starting from 100, Gardner stopped at 65 and replied that he had forgotten what he was doing.
1. Animals That Sleep
There are so many sleeping facts about animals that are super interesting. Here’s a list of a few our faves. Three eye-opening facts about how the animal kingdom sleep.
- Cats can sleep up to 13 - 14 hours, on average. They mostly roam around at night to hunt, which is typically in the wild. This is true for biggers cats, too - the mighty lion, king of the jungle.
- A desert snail can sleep up to THREE YEARS! It's not uncommon for any snail to nap for a week, either. They hibernate when the air gets too dry because they need moisture to stay alive.
- We all know about bats sleeping beside down, but they do it for a reason. It makes them less obvious prey and it allows them to take off at any moment if they are any any treat.
