Sleepy much? Here are some interesting facts about sleep

Given that we spend roughly a third of our lives asleep (around 25 years), we thought we'd go deeper into the world of sleep to unearth some intriguing statistics about sleep and what we do when we're sleeping.

Here is the list of some facts about sleeping that were unexpected and mind blowing!

Some of us have black-and-white dreams

About 12% of people dream in black and white nowadays. While this may appear surprising, it was closer to 75% prior to the introduction of colour television.

We are the only mammals capable of postponing sleep
 

We can keep ourselves awake even when our bodies tell us it's time to sleep. Other mammals, on the other hand, are forced to sleep when their bodies demand it.

Men and women sleep in various ways
 

The circadian rhythms of men and women differ slightly. Men have a six-minute longer circadian rhythm than women, which means they are less exhausted in the evening. Women are more likely than males to have a shorter cycle, which means they get up sooner.

Sleep improves your immunity
 

It's recommended that you get seven to eight hours of sleep per night throughout flu season to keep your busy immune system in good shape.

Approximately 15% of the population sleepwalks
 

According to the National Sleep Foundation, 15% of people sleepwalk, and you can supposedly wake someone who is sleepwalking.

A person should take 10-15 minutes to fall asleep
 

This is the average length of time for falling asleep. If you fall asleep in less than 5 minutes, you're probably suffering from sleep deprivation.

No one sleeps the whole night through
 

We all wake up multiple times during the night, most of the time without recognising it, whether it's from being too hot or chilly, partner movement, children, or noise. Waking up in the middle of the night is nothing to be concerned about; we go through numerous stages of sleep, each punctuated by occasional awakenings.

When we sleep, our perception of smell declines
 

Noise has been demonstrated to rouse us up when we sleep, whereas odors do not, which is why fire alarms were designed.

We couldn't leave you without a few amusing facts. There are some more fun facts also such as, you can't sneeze in your sleep, giraffes only need 1.9 hours of sleep per day, and babies can deprive their parents of 44 days of sleep every year!

In general, we should strive to get 7–9 hours of sleep each night. It may appear simple, but in our neon-lit, frantic, and noisy existence, it is more difficult than we would want. All we can do is continue to make an effort to provide sleep with the space it requires.
