You must score eight hours of sleep per night but let’s be honest, we are all guilty of neglecting this requirement.

The data of the Centers for Disease Control and Prevention (CDC) found that more than 30% percent of people reported that we slept less than seven hours in a 24-hour period, and 37.9 percent have fallen asleep involuntarily during the day.

Night Sleep is one of the most important things you can do to keep your body healthy.

In fact, sleep can aggravate health problems and interfere with the body’s natural ability to heal itself.

It has been proven scientifically that cutting down sleep from eight hours to four hours per night even to a period of less than a week can produce changes in your body. 

Lack of sleep has been linked to serious health problems which are coming ahead in this article.

Ist check that how much sleep actually our body requires.

  • Newborns: 14 to 17 hours
  • Infants: 12 to 15 hours (ages 4 to 11 months)
  • Toddlers: 11 to 14 hours (ages 1 to 2)
  • Pre-Schoolers: 10 to 13 hours (ages 3 to 5)
  • School Age: 9 to 11 hours (ages 6 to 13)
  • Teens: 8 to 10 hours (ages 14 to 17)
  • Young Adults: 7 to 9 hours (ages 18 to 25)
  • Adults: 7 to 9 hours (ages 16 to 64)
  • Older Adults: 7 to 8 hours (65+) 

Sleep Timings

During the early 1900s, the average night sleep time was 9 hours.

By 1975 it dropped down to 7.5 hours.

By 2002 it fell down to 6.9 hours.

Today most people average just five to six hours of sleep per night. Fast and unhealthy lifestyle made most of us sleep-deprived. 

Symptoms Of Sleep Deprivation

There are specific symptoms of sleep deprivation. Some of the common symptoms are mentioned below.     

1) Lack Of Concentration

A very prominent sign that your sleep-deprived is that you have a lack of concentration.

Now the ability to focus calls for a lot of brainpower and you just don’t have the energy to concentrate.

So you’ll notice that you just can’t focus on anything and you’ll find yourself spacing out or maybe forgetting things and of course, this is because of sleep deprivation.

2) Weak Decision Power

Another symptom of sleep deprivation is that you feel confused while making decisions and sometimes make bad decisions.

Probably you may never make an important decision in your life when you are sleep-deprived.

It has been found scientifically that when you’re sleep-deprived your brain has reduced access to higher-level cognitive functions.

The decision-making part of your brain seems to be reduced inactivity, so it’s just a really bad idea to make important life decisions on a bad night’s sleep.

3) Feeling Stress

If you are sleep deprived, you will feel very very stressed sometimes without any good reason.

Now, this is pretty intuitive because when you sleep it gives your body a chance to wind down and to reconcile your emotions and to basic recharge.

That’s how you sort of alleviate yourself from the daily stresses of life.

So if you’re not giving your body a chance to rejuvenate itself you know to expect to be more stressed. 

4) Slow Reflexes

Slow reflexes and poor hand-eye coordination is also a symptom of sleep deprivation.

So again this was proven with a study and when subjects were sleep-deprived they performed quite poorly on like motor skills tests and they had very slow reaction times.

So driving or doing anything that requires mental agility is actually a very bad idea when you’re sleep-deprived.

You’ll find yourself nodding off at the wheel and that’s very dangerous.

Actually, when you’re sleep-deprived it produces the same type of effects as if you are drunk. So basically you could roughly equate sleep deprivation with intoxication and that’s scary. 

5) Need An Alarm To Wake up

Another way to realize that you’re sleep-deprived is that you would need an alarm clock to wake up.

If you wake up without an alarm clock like on your own feeling refreshed that is how you know that you’ve had enough sleep.

So ideally, you would wake up before work or whenever you need to wake up on your own.

You can’t actually train yourself to go to bed and wake up at the same time every day. You need the discipline of course but it is possible.

Your biology is trained to go to bed and wake up when the Sun sets and there’s not very much variety in the time for that so it’s technically possible to really get your body into a routine. 

4) Overeating

Another sign that you’re sleep-deprived is that you tend to overeat.

Again they’ve done studies on this lack of sleep caused your body to produce the hormone called Ghrelin and that is the hormone that’s responsible for making you feel hungry.

So your body produces more of this so you’re much more prone to go for the high-calorie high-fat food.

You’ll try to eat things like muffins and donuts. So it’s just another reason to get more sleep.

Some of the major negative effects of sleep deprivation on body and mind are 

1) Negative Emotions & Attitude

Basically, your ability to experience positive emotions and as well as empathy which is your ability to genuinely connected with others is like severely impaired. 

So when you are sleep-deprived you have a reduced ability to handle your emotions so you’re much more likely to get upset if something doesn’t go your way.

If you’re sleep-deprived it just sucks all the joy out of your day.

You might as well just write off that day because it’s gonna be very difficult for you to maintain a positive attitude and to find opportunities to experience joy and happiness. 

2) Feelings of Loneliness

If you experience more feelings of loneliness and helplessness this is also a signal that you are sleep deprived.

So according to a British survey poor sleepers are seven times more likely to feel alone and this is a very important finding.

Who wants to feel alone and helpless? So you can reduce those feelings by changing your sleeping habits.

3) Central Nervous System

Your central nervous system is the information highway of your body and proper sleep is necessary to keep it functioning properly.

Sleep deprivation can disrupt how your body usually sends information during sleep.

Pathways between nerve cells neurons in your brain help you remember new information.

As mentioned earlier that sleep deprivation leaves your brain exhausted so it can’t perform its duties as well.

So, you may find it more difficult to concentrate or learn new things. 

4) Affects Your Immune System

Sleep-deprived people are three times more likely to catch a cold which obviously means that their immune system is not working efficiently.

So to rejuvenate your immune system take care of yourself and get sleep because otherwise you’re just gonna be sick a lot more often and that is no fun.

5) Sleep Deprivation Causes Obesity

Sleep deprivation is another risk factor for becoming overweight. 

There are numbers of studies finding a direct connection between sleep deprivation and weight gain.

In a than their counterparts who slept seven to nine hours a night.

Those averaging 5 hours of sleep were 73% more likely to be overweight.

In a Harvard Nurses Health Study, women who slept less than five hours per night were 30% more likely to gain at least 33 pounds over a 10-year period of time than women who slept seven to eight hours a night.

Researchers measured growth hormone in levels in 20-year old men who restricted to six hours of sleep every single night.

Growth hormone regulates both blood sugar and body proportion a fat to muscle. without adequate sleep, the production of growth hormone goes down and that study concluded that the sleep you’re getting right now in your 20’s and 30’s can affect your health when you get older.

In a study carried out in 2014 by teaching hospital associated with Harvard, the researchers determined that those who obtained a total of 8 hours of sleep they burned twice as much fat as those who did not get enough rest. 

Actually, sleep affects the levels of two hormones Leptin and Ghrelin which control feelings of hunger and fullness leptin tells your brain that you’ve had enough to eat.

Without enough sleep, your brain reduces Leptin and raises Ghrelin which is an appetite stimulant.

The flux of these hormones could explain night snacking or why someone may overeat later in the night.

Lack of sleep can also contribute to weight gain by making you feel too tired to exercise or any other healthy physical activity like sports.

Long daytime rests can negatively affect night sleep.

If you rest in the daytime than restrict yourself to up to 30 minutes and abstain from doing as such late in the day.
