Sleep Deprivation and Work Performance

It is well known that the lack of sleep can be extremely damaging to both your mental and physical health. Sleep is required for our bodies to function normally. Without enough of it, people feel tired and lack the motivation to perform at their best. The problem with insomnia can be severe because the person may not get quality restorative sleep. People who go to bed late can often experience sleep deprivation. In addition, those who suffer from chronic insomnia are less efficient in many aspects of life including work performance, decision making, memory, and attention control. This article will cover a number of studies on how poor sleep affects workplace tasks. 

Sleep Cycle of Human

The human body is designed to function on less than six hours of uninterrupted sleep per night. The average adult needs between seven and nine, but even if we get that amount it can be hard to maintain because our bodies need time for restorative processes. During these times when we’re not sleeping, our brains begin to release chemicals like cortisol which make us feel tired and stressed out. A lot of people find they have trouble getting back into their normal routine after taking long breaks from being awake, and this causes them stress and anxiety in addition to making it harder to focus at work or school.

Impacts Of Sleep Deprivation

  • Sleep deprivation affects almost everyone 
  • It makes it more difficult to concentrate and learn new things
  • People who don’t get enough shut down parts of their brain
  • Some people also experience depression and/or other mental health issues due to proper sleep
  • There’s no real way around it; you just need to change how much sleep you’re getting every day so that you can stay healthy and productive throughout the year!

Symptoms of Deprivation


It is one of the main reasons why people go to bed later and wake up earlier. This means that many people will start feeling sleepy during daytime hours instead of going to bed early. If someone doesn’t fall asleep until 4 am, then by 9 am or 10 am they’ll likely still have feelings of fatigue rather than having gotten adequate amounts of sleep. Since there isn’t really an ideal duration of sleep, you should aim to try to get about eight hours each night. When you’ve got too little sleep, you may notice yourself needing caffeine and sugar to keep you alert. You may actually lose weight and gain muscle mass if you eat properly while trying to sleep longer. Sleeping past noon won’t help either since your biological clock will kick in and cause you to want to sleep again soon anyway. You need to sleep and wake up early. As long as you aren’t falling asleep in class or doing anything dangerous, staying up late shouldn’t hurt anyone too badly unless you have medical conditions related to insomnia.

Memory Loss & Confusion

Your memory functions best when you sleep deeply and regularly. Even though you could potentially remember everything you did today, tomorrow morning your short-term memories will fade away faster than usual – especially if you didn’t get any quality sleep last night. Because of this, you’ll probably struggle to recall information such as names and faces. However, learning something new requires energy, which you will definitely be lacking without good sleep. One thing you can do is try taking notes on paper before heading to bed and reading them first thing in the morning. That helps give you a clearer sense of what was learned. You can also take naps 2 to 3 times to combat memory loss and fatigue. Napping for 10-20 minutes is ideal for all humans. 

Decreased Ability to Focus

When you haven’t been able to spend sufficient time resting in between waking periods, your ability to think clearly becomes impaired. To function effectively, your mind needs regular downtime so that all its various aspects operate smoothly. While this means that you may need less concentration and attention span overall, you’ll still have plenty left over once you’ve had a few days’ worths of uninterrupted slumber. Just know that keeping track of multiple tasks simultaneously takes a lot of effort, and you may not always succeed in completing those tasks successfully.

Increased Anxiety and Stress Levels

Since your nervous system has already begun releasing adrenaline and noradrenaline even before you’ve fallen asleep, you may end up experiencing increased levels of both hormones as you lie there waiting for the next period to arrive. These two neurotransmitters are responsible for causing an increase in heart rate, blood pressure, breathing rate, and core body temperature. All of this contributes to creating an elevated state of arousal known as “the fight or flight response.” With constant exposure to high levels of these hormones, it only stands to reason that you’d eventually become anxious and tense. The solution to this problem is simple: Get better sleep. Depression / Mood Swings

While depression isn’t necessarily caused by lack of sleep per se, it’s certainly easier to fall into a depressive cycle after having trouble sleeping all day. If you’re feeling down because you don’t feel rested enough, you may find some relief simply from getting more restful sleep. Sleep deprivation also tends to make people irritable, grumpy, and prone to mood swings. So instead of letting low-quality sleep ruin your entire day, turn things around with quality sleep! It just makes life much happier during the daytime hours.

Low Energy Level

If you’re tired most of the time, then chances are that you’re not receiving adequate amounts of sleep every night. This leaves you with very little reserve power throughout the day, making you weaker and slower at performing physical activities. Your brain doesn’t receive nearly enough nutrients, leading to poor decision-making skills, decreased productivity, sluggishness, fatigue, and other problems. Try going to bed earlier to catch more dreams each evening and see how well you fare the next day. Remember: Quality sleep improves your mental clarity, reduces stress, increases motivation, boosts confidence, and enhances social interactions.

Sexual Dysfunction

Many men experience sexual dysfunction due to insufficient sleep, but women rarely suffer from similar issues. Women tend to naturally produce higher quantities of estrogen than their male counterparts, so they often experience fewer negative hormonal effects from reduced sleep cycles compared to males.


Sleep deprivation affects almost everyone every day. Apart from this, your sleeping position also affects your health. The effects of sleep deprivation vary from person to person, but in the end, it will lead to your inability to function properly throughout your day. It is extremely important to take note of how long you spend awake each day, to help identify patterns and establish what causes them, as well as what you can do to combat sleep deprivation and the resulting symptoms.
