Lack of Sleep and It's Obvious Side Effects

Everyone has pulled an “allnighter” at least once in their life.

Whether it was at your first sleep over as a kid or a night in college, everyone has stayed up throughout the night. Think back to that sleep over or that night of studying and remember how you felt the next day.
Chances are you weren’t feel as fresh as a daisy. So what happens to our bodies when we lack sleep? Is staying up all night good for us? Check out some of the side effects of not catching enough Z’s.

Why we do we sleep?


Lack of Sleep and It's Obvious Side Effects


We sleep because we are tired. We sleep because we had a long day. We sleep because we just like to sleep! But why do we scientifically fall asleep? If you have ever wondered about the science behind sleeping, here are all of your answers.
We spend one third of our entire lives asleep. That’s a lot of time. Sleeping is an essential part of living. It is extremely important for our general health and wellbeing. Although there is not one specific reason for why fall asleep, scientists have been coming up with multiple theories on why our bodies must fall asleep.


INACTIVITY THEORY

The first theory that was ever brought to light is called the inactivity theory. Also called the evolutionary or adaptive theory, this theory suggests that our bodies fall asleep as a protective mechanism.
It explains that when in a vulnerable situation where an organism would be harmed, our bodies go into a survival mechanism and fall asleep.
This may not make sense when it comes to humans but the idea is that animals or other organisms were in a state of inactivity, helping them remain quiet so that the other organism trying to harm them would not notice where they were.
This theory was soon overlooked because it has come to our attention that remaining awake and alert in times of activity is necessary for safety.

CONSERVATION THEORY

The next theory that was brought up to explain why we sleep is called the energy conservation theory. During natural selection and survival of the fittest, organisms needed to keep their energy levels high.
Sleeping gives our bodies a chance to rest and be ready to take on anything that comes along once we are awaken. Conserving energy is important for when that energy is needed in full effect.

RESTORATIVE THEORIES

There are multiple restorative theories that suggest we need sleep to help restore many of the body’s functions. Sleeping gives our bodies the chance to rejuvenate.
During the day, many activities are done and our bodies can eventually wear out. By going to sleep, you give your organs a chance to reset.

BRAIN PLASTICITY THEORY

One of the last and most recent theories on the question “why do we sleep” has to do with brain and cognitive function.
Brain plasticity is the way our brains grow and develop throughout life. Sleep plays a major part in brain development, especially in infants and young children. This may explain why most infants and children spend about 13-14 hours each day asleep.
Although there is not one specific answer as to why we fall asleep, all of these theories make sense. So what happens when we lack of sleep.

Side Effects of Not Getting Enough Sleep


Side Effects of Not Getting Enough Sleep


Think back to a time when you didn’t sleep enough. How did you feel? Tired? Lazy? Dizzy? Did you find it hard to concentrate?
Lack of sleep can take a serious toll on our bodies and can affect how we go about the rest of day. Some of the side effects of not sleeping enough can be actually dangerous while others just put a damper on our lives.
  • Sleep deprivation can lead to some serious health risks.

You eat right, you workout, you take your vitamins, but you only sleep 5 hours a night. Well, no matter how healthy you are throughout the day, missing out on those extra  hours of sleep can actually reverse all of that.
Research shows that lack of sleep increases your chance of developing some of these diseases: diabetes, stroke, heart disease, high blood pressure, and obesity.
  • Sleep deprivation can cause depression.

Rather than thinking about a time when you didn’t get enough sleep, think about the last time you slept for a good 9 hours. How did you feel after? Probably like a million bucks! Not getting enough sleep can increase feelings and symptoms of depression.
There was a study done in 2005 that showed that people who got less than six hours of sleep each night were at a much higher risk for depression and depression like symptoms than those who slept longer.
  • Sleep deprivation can lead to impaired judgement.

Think alcohol can lead to some bad judgement calls? Well, so can lack of Z’s.
Not getting enough sleep actually affects the way our brains interprets people, places, and events. If you have some big decisions to make, be sure you are getting enough shut eye.
  • Sleep deprivation can cause weight gain.

Ask any fitness professional and they will tell you that getting enough sleep is just as, if not more, important as dieting and exercise. Keeping a regular sleep schedule helps keep your energy levels up, allowing you to push through your workouts. It also keeps your appetite at a normal level.
If you aren’t sleeping enough, your body looks for energy. If you are not sleeping, your body immediately taps into the second place to get energy which is from food. This will increase your appetite, causing you to consume excess calories. All of these factors can lead to weight gain.
Sometimes hitting that snooze button can do you good. The theories behind why we sleep all go back to keeping you healthy. Sleep is your friend!
Have you ever missed out on a few hours of sleep and noticed some of these side effects? Let us know how a lack of sleep has affected your life.
