Top Ten Negative Effects of Sleep Deficiency

Everyone has passed through a night, not slept, or hardly closed an eye for other reasons. Still others complain that they have slept very badly, less than a few hours, sometimes even. And most people experience negative consequences of having to sleep too little or not after one night. Fatigue, for example. However, this phenomenon is by no means the worst, nor the most serious, consequence of sleep deprivation. What people often do not realize is that sleeping is not deadly, and it does not take that very long!


The American Randy Gardner did not want to believe that one needs sleep. He therefore conducted a self-experiment, and stayed awake for eleven days and 24 minutes, without the use of drugs, drugs or other stimulants. In the end he had to give up, he suffered from paranoia, hallucinations and a whole range of other medical symptoms.





Not convinced of the need for sleep? Remember, for example, that sleep abstinence is used as a torture mechanism and as a questioning technique by, for example, the Russian secret service. Lab research has shown that when lab animals are kept awake, they eventually die from sleep deprivation. For ethical reasons, this research has not been conducted on humans (but with animals, most people have less compassion, unfortunately).


Still not convinced? Then we suggest that you go through the list below. This is waiting for people who suffer from chronic sleep deprivation (but not, please note, people who spend a night or four sleeping "badly"!). Read more...


10. Car Accidents


No, lack of sleep does not directly lead to the crashing of your car, especially if the person who fails to sleep is not driving himself. But what is the case is that too little sleep can build up and can pop up at times when you can least afford it. For example, when you drive a car, over the highway.


Research has shown that motorists who have a lack of sleep do not have a good perception of the risk they take, but in fact it is more dangerous to drive with lack of sleep than when you are drunk! The difference is in the sensation; people who are drunk know (at least until they are too drunk) that they are under the influence. A person with a lack of sleep does not have to notice this until it is too late, and they hang in the crash barriers.


9. Inefficient Brain


Do you sleep less because you need more time to get certain things done? Then you can sometimes be deceived. Sleep deprivation makes our brains much less efficient. In other words, taking a nap regularly helps your brain stay effective and efficient. Just like a computer, which you have to close every now and then, we also have to give our brains time to sleep.


Studies show that people with lack of sleep pump a huge amount of blood to their 'prefrontal cortex' (forehead brain, used for conscious thinking and behavior). That has a reason, your brain works like a madman to overcome the effects of sleep deprivation. And all that energy is not put into other things, only in keeping your consciousness awake. Lost energy, and that while you thought you had won a few hours by not sleeping!


8. Short-Term Memory Loss


Your active working memory, with a time span of in fact only a few seconds up to a few minutes, needs sleep. Without this memory one can not even remember a few numbers, let alone memorize a telephone number. Observations do not come directly into the long-term memory, but always go through your short term.


If you have a lack of sleep, your short working memory is often one of the first to be affected. Of course it starts mild, you are confused and have difficulty remembering numbers, but it can get completely out of hand. Randy Gardner, our self-experimenter of the intro, was asked on the eleventh day of his experiment, which numbers one gets when repeatedly subtracting 7 of 100. He stopped at 65, he had no idea what he was doing in the name of God ... We ask ourselves the same ...


7. Long-Term Memory, too!


No short-term memory, but at least you still have memories from before your sleep-complete abstinence. Yet? No, you can already see the storm. Also your long-term memory will eventually go to the sharks. Our brain needs sleep in order to integrate everything, to put it in order, and to process it. If we do not get that sleep, then this does not happen. You can forget to learn something, if you have good sleep deprivation. Especially when it comes to skills, forget it.


6. Notice zero point zero


Do not underestimate a normal person. The waking man is extremely good at paying attention and being alert in his or her environment. We can perceive, feel, or hear the smallest movements when we commit ourselves to them. A serious lack of sleep, however, ruin all those 'super' forces.


Sleep deprivation makes us more or less deaf, dumb and blind for things that happen around us. Not literally, of course, you still see (later more about what you see exactly), but you hardly notice it anymore. You are literally unable to concentrate or direct your attention. You can only react instinctively to distress signals, and even you do that badly and slowly. That is why people with a lack of sleep often feel aloof, and distracted from the reality around them.


5. You can forget plans


After about 36 hours of no sleep, your ability to plan and coordinate your time and actions is totally lost. Tests have shown that an important part of your brain, that part that takes care of the planning of starting and stopping activities, simply ceases to work, after a few days of sleep deprivation. That is why people with a lack of sleep easily stick in a behavioral circle, and repeat the same action, or continue to walk around in a cloud of doubt, instead of making decisions.


For example, which rice you want to buy in the supermarket. Most of us do not take that long. Some people may briefly inform themselves about the caloric content, or look for the sustainability logo, but a sleep-limited individual may need minutes to decide to buy rice. And you can imagine that a shopping trip will take a long time, if you need at least 10 minutes for each product choice!


4. Habits prevail


Exactly, if you are no longer able to make decisions, then you fall back on your habits. These are built into your automatic thinking pattern, and therefore require less intervention from your prefrontal cortex (see number 9). Your habits are therefore the only thing left over.


It can of course work out well, if your habits are generally positive, but in most cases this is not the case. People with a lack of sleep, for example, eat significantly more fast food, fall back on old habits (smoking) and are generally less able to think about the consequences of these actions.


3. Risky


Moreover, studies have investigated whether sleep deprivation has an effect on your own sense of risk, and yes, there is a connection. People with too little sleep are less able to assess risk properly. In other words, your sense of risk is reduced. One of the reasons why you think you can drive a car, do not sleep after two nights.


This has been investigated with card players who continue until late at night, and get too little sleep. These players soon seem to be trapped in a single strategic plan-the-campaign, and can no longer adjust their game, regardless of how Lot is turning or turning. When you normally thrown the towel in the ring, you just continue betting and raising. Not smart…


2. Dying brain cells


All the above things are worrying in an everyday context, but if you stay safe in your own room, surround yourself with only healthy food, lack of risky business, and enough material to keep yourself alive? Then you are not there yet.


In mice, it has been found, among other things, that after a long period of no sleep, approximately 25% of the brain cells give it to them. They die. Other studies showed that sleep deprivation reduced the integrity of the white part of your brain. It will not be immediately deadly, but it is not healthy at all! Read more...


1. Mania

Finally, if you think you have had everything, then you still have mania. Mania is more or less a collective name here for many symptoms, such as psychosis, paranoia, hallucination, aggression and so on. In other words, you become upset mentally.


"Finally, good news: most of the above effects disappear immediately when you resume your sleep (unless of course you crash yourself into a car ...). Our Randy, for example, slept after his eleven days record attempt (you can find him in the Guinness book of Records, incidentally) about 14 hours the first night, and 10 hours the next night. Then he was completely recovered. Of course, scientists do not guarantee that this will always be the case. If you damage your brain, who knows how much is still intact, after sleep recovery. The conclusion should therefore be, although the cliché is: "do not try this at home!"
