Impact of Sleep on Health. Why Sleep is Important.

February 8, 2021 by Prasanna

Importance of Sleep Essay: Sleep is one of the most important things you need to do for your body because it is your bodys way of recharging its batteries. When you begin to feel sleepy at night, it means that you have reached the limit that your body has, and you should sleep so that you do not over-exert yourself.

Many people dont get enough sleep at night, mostly because so many of us have turned into night owls who love to do so many things at night instead of the daytime. These are terrible habits, and we must learn to get rid of them by paying attention to the importance of sleep. For example, a bad habit like this would be watching TV shows late at night despite knowing that we have to wake up early the next morning.

Regular Exercise Can Absolutely Help You Sleep

Can exercise help you sleep? Absolutely. And if youve never experienced that immediate sleep-inducing exhaustion one might experience after a day of hiking or a grueling boot camp class, theres a ton of scientific research to back up this claim, too.

In one study published in the journal Sleep Medicine, individuals with a self-reported sleep time of less than 6.5 hours completed moderate-intensity workouts four times a week for six weeks. At the end of the experiment, they reported getting an extra 75 minutes of sleep per night more than any drug has helped deliver, according to the study authors.

Exercise actually has a chemical effect on the brain. Physical activity creates more adenosine in the brain, and adenosine makes us feel sleepy, says Winter. The harder we work out, the more driven we are by this chemical to sleep.

Healthier Heart

While youre sleeping, your blood pressure falls and gives your heart a chance to rest. It also allows your blood pressure to regulate. When you cut that time short, your blood pressure stays higher longer during each 24-hour period. Overtime, high blood pressure can lead to heart disease or stroke.

Weight Control

When youre sleep-deprived, it affects the hormones in your brain that regulate appetite. Lack of sleep not only knocks your appetite hormones out of balance, causing you to eat more, but you also have less motivation to get moving. Its a recipe for weight gain. Not to mention, people who havent gotten enough sleep have a tendency to choose unhealthy, higher calorie comfort foods.

Sleep Helps With Weight Management

Time and again, people struggle with weight issues. They claim to have tried everything follow a restrictive diet, eat healthily, and exercise regularly.

But apparently, getting your ideal weight requires more than that. Aside from eating healthy, dieting, and exercising, the importance of rest and sleep should not be overlooked. You need it in achieving your ideal weight.

Shape.com explains why it is very important to get enough sleep if you want to lose weight:

Within just four days of sleep deprivation, your bodys ability to properly use insulin becomes completely disrupted. In fact, the University of Chicago researchers found that insulin sensitivity dropped by more than 30 percent.

Heres why thats bad: When your insulin is functioning well, fat cells remove fatty acids and lipids from your bloodstream and prevent storage. When you become more insulin resistant, fats circulate in your blood and pump out more insulin

Eventually, this excess insulin ends up storing fat in all the wrong places, such as tissues like your liver. And this is exactly how you become fat and suffer from diseases like diabetes.

The Impact Of Sleep Deprivation

Sleep deprivation is a serious issue in the United States. It’s estimated that one in five Americans are chronically sleep deprived. However, even one night of sleep deprivation can put a person at risk of illness or injury. Here are some common way that sleep deprivation can impact your health and safety:

Poor Sleep Can Increase Your Calorie Intake

Why good sleep is important.

People who get poor sleep tend to consume more calories.

A study of 12 men found that when participants were allowed only four hours of sleep, they ate an average of 559 more calories the following day, compared to when they were allowed eight hours .

This increase in calories may be due to increased appetite and poor food choices, as mentioned above.

However, it may also simply be from an increase in the time spent awake and available to eat. This is especially true when the time awake is spent being inactive, like watching television .

Furthermore, some studies on sleep deprivation have found that a large portion of the excess calories were consumed as snacks after dinner .

Poor sleep can also increase your calorie intake by affecting your ability to control your portion sizes.

This was demonstrated in a study on 16 men. Participants were either allowed to sleep for eight hours, or kept awake all night. In the morning, they completed a computer-based task where they had to select portion sizes of different foods.

The ones who stayed awake all night selected bigger portion sizes, reported they had increased hunger and had higher levels of the hunger hormone ghrelin .


Poor sleep can increase your calorie intake by increasing late-night snacking, portion sizes and the time available to eat.

What Happens During Sleep

Every night you leave wakeful consciousness and descend into a state of sleep. But most people have no idea what happens after they close their eyes.

While youre off in dreamland, several physiological changes in your body take place. Changes in your temperature, heart rate and brain activity all occur during sleep. Although physiological demands are decreased, several things are still going on.

As you pass through the various stages of sleep, your body cognitively and physically restores itself. For example, cells synthesize protein, tissues repair themselves and growth hormones are released while you are sleeping.

Sleep may also help your brain reorganize and retain memories. While youre awake, your brain is receiving lots of information and images. You might even be trying to learn new things. While youre asleep, your brain may replay and organize the events, memories and information from the day. During sleep, your brain might be consolidating new memories and processing information all of which help with cognitive function.

How To Sleep Better

Sleep Council: Why we need to sleep for health and wellbeing

If youre experiencing mild, occasional problems with sleep, try these simple strategies from sleep expert Michelle Drerup, PsyD, DBSM.

1. Treat getting enough sleep as if it is as important as taking medicine.

With all the demands on our time every day, you might put a good nights rest at the bottom of your priority list. But Dr. Drerup says we need to schedule adequate time for sleep.

Its very easy to stay up late and burn the candle at both ends, she says. However, when you do that, you quickly run into a problem of dealing with sleep deprivation.

2. Keep a consistent wake time.

Wake up at the same time every day, including weekends or days off. Waking at the same time every day will actually help you to sleep better at night. A fixed wake time helps to build a strong desire for sleep throughout wakefulness. This sleep drive gradually builds, and shortening it by sleeping in will make it harder to fall asleep the next night. Sleeping in on the weekend makes it much more difficult to wake up earlier on Monday morning.

It also is important, Dr. Drerup says, to do some relaxing activity such as taking a warm bath or reading a book before bedtime. By making these activities part of your bedtime ritual, you can train yourself to associate these activities with sleep. This association will help you to move more easily into slumber.

3. Put away the smart phones and tablets.

4. If you do wake up during the night, avoid looking at the clock.

Why Cant I Fall Asleep

Many things can make it harder for you to sleep, including:

  • Stress or anxiety
  • Certain health conditions, like heartburn or asthma
  • Some medicines
  • Caffeine
  • Alcohol and other drugs
  • Untreated sleep disorders, like sleep apnea or insomnia

If you’re having trouble sleeping, try making changes to your routine to get the sleep you need. You may want to:

  • Change what you do during the day for example, get your physical activity in the morning instead of at night
  • Create a comfortable sleep environment for example, make sure your bedroom is dark and quiet
  • Set a bedtime routine for example, go to bed at the same time every night

Sleep Can Help You Experience Less Pain

Another interesting importance of rest and sleep is its ability to increase your tolerance for pain. You might be asking, What has sleep got to do with my sensitivity to pain?

Well, there are a number of studies supporting this claim.

The most recent one is a 2015 study performed by a fellow from the Norwegian Institute of Public Health in Bergen, which was published in official publication of the International Association for the Study of Pain.

This study, which was featured in Science Daily magazine, reports that people with insomnia and other sleep problems have increased sensitivity to pain.

While this may not directly affect people who are not experiencing pain, according to Annahad OConnor of the New York Times, scientists believe this has implications for people with chronic pain.

It could also have an impact on the effects of painkillers which appear to the be blunted after chronic sleep loss, he adds.

So, there you go. If you want to be more tolerant to pain, better get enough sleep.
