Most people say that we really need seven, eight, or more hours of sleep on a regular schedule each night. But actually, it is not all about total hours of sleep but the quality of sleep each night, so you will recover and be ready for the next day’s activity.

Sleeping each night helps the body heal itself, activates the immune system, and gives your heart a break. Beyond that, sleep experts are still trying to learn more about what happens once we fall asleep. These are the 12 facts about sleep that you may not know.

1. Losing just an hour of sleep could give a big impact

2. It takes 10-20 minutes to fall asleep

4. Bright screens can affect your circadian rhythm

Healthy sleep hygiene, like a good habit of putting your phones away before bedtime, is highly recommended to prepare yourself for the time to rest. The natural light and dark cycle of the day helps your body know when it is time to be awake and alert and when it is time to shut down and get some rest. If your eyes are constantly exposed to bright lights like those on the screens of your phones, TV screens, video games, and more, this will gradually give your eyes a hard time sleeping.

5. You should always consider taking a nap

A short nap, like twenty to thirty minutes, is advisable and recommended for the purpose of short-term alertness without feeling too groggy to get back to your day instead of giving your body back just like recharging a bit.

6. Sleep deprivation will kill you more quickly than food deprivation

Those people deprived of sleep for research initially noticed the effects on their alertness, mood, and physical performance, but the awareness dropped off after the first few days.

7. Sleeping on your front can aid digestion

Hands should apparently be placed above the pillow to create a “freefall” position, and lying on your left side can help reduce heartburn.

8. 24-hour internet access is one of the biggest sleep distraction

Experts say one of the most alluring sleep distractions is the 24-hour accessibility of the internet. Having an internet connection will just give you a loss of focus, lead you to uncontrollable direct accessibility to your gadgets, and offer temptations like continuing watching the video and following social media platforms, which will deprive you of sleep.

9. Avoid the habit of compensating the missed hours of sleep

According to a study, sleeping extra to compensate for the missed sleep times decreased reaction times and the ability to focus. It simply means that you need to practice good sleep hygiene and get 7-9 hours of sleep as recommended.

10. Exercise may be helpful or not
