Sleep is an essential part of our daily routine, and we spend around one-third of our lives sleeping. Despite this, many people are not aware of the fascinating facts and mysteries surrounding sleep. Here are 5 fun facts about sleep that you may not know:
Some of us dream in black and white
According to The Sleep Journey, 12% of people still dream in black and white. In the 1940's three-quarters of Americans reported they "rarely" or "never" dreamt in color!
Sleep boosts the immune system
The Sleep Foundation says, "Sleep provides essential support to the immune system. Getting sufficient hours of high-quality sleep enables a well-balanced immune defense that features strong innate and adaptive immunity, efficient response to vaccines, and less severe allergic reactions." So if you're feeling sick, get some sleep!
Sleepwalking is more common in children than adults
Sleepwalking is a sleep disorder that affects around 5% of children and is less common in adults, according to The Sleep Foundation. Sleepwalking usually occurs during the first few hours of sleep, during the deep sleep stage. While sleepwalking, a person may sit up, walk around, or perform routine activities without being aware of their actions. Sleepwalking is usually harmless but can be dangerous in some cases.
You dream every night, even if you don't remember them
Many people believe that they only dream occasionally, but the truth is that we all dream every night, even if we don't remember them. Dreams occur during the REM (Rapid Eye Movement) stage of sleep, which happens about 90 minutes after falling asleep. While some people may not recall their dreams, others may remember vivid and elaborate dreams.
The record for the longest time without sleep is 11 days
In a famous experiment, a man named Randy Gardner stayed awake for 11 days straight, breaking the world record for the longest time without sleep. During this time, Gardner experienced mood swings, hallucinations, and impaired cognitive function. While it is not recommended to stay awake for this long, some people with rare genetic conditions can function on very little sleep.
Sleep is an essential part of our lives, and these fun facts demonstrate that there is much to learn about this fascinating aspect of our existence. Whether you are a dreamer, a sleepwalker, or simply curious about the mysteries of sleep, these facts are sure to spark your interest and encourage you to prioritize getting enough rest.
