Hey there! Welcome back to another fascinating post on Peace Of Mind.
Today we will take a look at different stages of sleep and when do they occur during night.
There are four stages of sleep, consisting of both REM and Non-REM sleep, that we cycle through each night. The stage of Non-REM sleep happens when you began to fall asleep and usually lasts only a few minutes.
This next stage of non-REM sleep is a period of light sleep before you enter into a deep sleep stage, and it lasts for roughly 25 minutes. These final stages of non-REM sleep are the deepest sleep stages.
Stages three and four are known as slow wave, or delta sleep. Your body performs a variety of important health-promoting tasks in these final non-REM stages.
The rapid eye movement stage occurs about 90 minutes after you fall asleep, and is primarily known as “dreaming” stage of sleep. REM sleep lasts roughly 10 minutes the first time, and increasing with each REM cycle. The final cycle of REM sleep usually lasts for roughly 60 minutes.
When you fall sleep at night, you cycle through all of these stages of sleep multiple times — roughly every 80-90 minutes or so.
Check out some amazing facts about snoozing :
• Human beings spend 1/3 of their lives sleeping while cats spend roughly 2/3 of theirs sleeping.
• Other animals, such as koala and bats, can sleep upto 22 hours a day!
• Newborn babies need roughly 14 to 17 hours of sleep per day, while teenagers require 8 to 10 hours each night. Most adults need 7 to 9 hours of sleep.
Lack of sleep :
Sleep Deprivation can have a huge negative impact on health both physically and mentally. Even as little as 72 hours without sleep can cause mood swings, difficulty functioning and altered perception. Energy levels naturally dip at two distinct times of the day : 2 a.m. and 2 p.m.
This explains the post-lunch fatigue that some people feel during middle of the day.
