Side Effects of a Lack of Sleep
Do you suffer from sleep deprivation? Most teenagers need 8-12 hours of sleep. Lack of sleep can cause delayed reactions or even learning disorders. Prolonged loss of sleep occurs for physical and mental reasons and has harmful physical and mental effects to the human body.
Prolonged sleep is caused by many different functions of the body. An important cause of prolonged sleep is a teenagers biological phase-delay or a tendency to fall asleep and wake up at different times. Changes that occur at puberty in the internal body clock governing their circadian biological rhythms can cause them to sleep irregularly(Johnson, 3).
Another good reasons why teenagers do not get enough sleep is because they simply do not make time for it. Some schoolwork, sports, jobs, girlfriends or boyfriends may take up most of a teenagers time or cause them to have stressful sleep(Johnson 3).
Sleep deprivation can cause slow reactions of time. It may also cause headaches and nightmares more frequently. The mind will fall asleep if it cannot get enough sleep causing it to not function properly. Some side symptoms of chronic lack of sleep are feeling fatigue or depression as body becomes drained (Haynes).
A major problem caused by sleep deprivation is behavioral changes such as: irritability, short temper, impatience, and stressful situations with more anger or sadness, also can cause more fear than they would normally have. If you continue to have prolonged lack of sleep your immune systems will begin to break down and become unstable to fight diseases (Haynes). To show how this is caused the researcher has done a study on how much sleep he/she got and how they felt that day.
Sleep deprivation has many harmful effects and there are some reasons you cannot stop prolonged lack of sleep. Sleep is essential to the studying and learning if you do not get enough sleep the mind can shut down from not having enough rest and can harm the human body.

Lack Of Sleep
It has always recommended that getting at least eight hours a sleep a night will make your life less complicated. Sleep deprivation is generally the cause of sleep disorders such as apnea, narcolepsy, and insomnia. Everyone knows without the proper amount of sleep, the mind will be groggy the next day, and as a result, many more mistakes will be made, meaning that you should get a full night's rest before taking a test or a little nap before a long drive in a car. But scientists are beginning to realize that sleep is not just a mental recharge, but also important for the body as well. When a person sleeps, the body and mind are working just as hard as when the person is awake, correcting chemical imbalances, assuring proper blood sugar levels for the next day, and maintaining the memory.
The effect of lack of sleep on the body is often worse than just not feeling like you got any sleep the next day. There can be serious health issues that result from not getting proper rest. The most obvious side effect of a lack of sleep is not having energy the next day. However it is more than feeling less than our best, the body actually performs less efficiently when we are tired or not rested. Performance, productivity, memory, and a whole lot of other things are all reduced when our body is running on less sleep than we need.
Physiologic studies suggest that a sleep deficit may put the body into a state of high alert, increasing the production of stress hormones and driving up blood pressure, a major risk factor for heart attacks and strokes. Other studies have found that sleep influences the functioning of the lining inside blood vessels, which could explain why people are most prone to heart attacks and strokes during early morning hours.
The body also needs rest to repair tissue, cope with stress, and recharge the immune system. A lack of sleep hampers these functions in the body. The ability to handle stress and fight off illness lessens when we fail to get enough...
Why do we sleep? Almost everyone seeks rest after a taxing day, through the act of sleeping. While there are individuals who claim to live without sleep, such instances are extremely rare. Sleep is a fundamental physiological need, a necessary aspect of brain function, where neural activity in the cerebral cortex is followed by a necessary period of inhibition to protect and rejuvenate nerve cells.
1. A yawn is often the first sign of sleep deprivation. If deprived of sleep for 18 hours, reaction times can double from the normal 0.25 seconds, and after 20 hours, drowsiness sets in.
2. Sleep is as essential to life as food, water, and sexual activity, a fact observed across the animal kingdom, from fruit flies to humans. However, the exact purpose of sleep remains elusive. It's not solely for muscle relaxation or to replenish energy, though these theories have been proposed.
3. One theory suggests sleep aids in processing the information the brain absorbs during wakefulness, while others propose that it serves as a mystery aid in skill acquisition.
4. Advances in sleep science, such as the research conducted by the Weizmann Institute of Science in 1994, have shown a correlation between the amount of REM sleep a person gets and their ability to recognize patterns on a computer screen. This is related to procedural memory, which involves repetitive tasks.
5. Declarative memory, which includes factual information like the names of U.S. presidents, is associated with rapid eye movement sleep, according to Harvard University's Dr. Siddiq Gode, who stated, "Our understanding of memory is always very naive."
6. Accidental discoveries in memory research have shifted focus. Dr. Gode and his colleague, Dr. Matthew Walker, have studied the impact of sleep on motor skill memory. They found that participants improved their accuracy by 60%-70% after training with their non-dominant hand, regardless of the time of day.
7. Surprisingly, those who showed the most improvement also spent the most time in non-rapid eye movement (NREM) sleep. For tasks involving vision or perception, participants benefited from deep sleep or a combination of slow wave and REM sleep, highlighting the varying effects of sleep on different types of training.
8. A restful night's sleep is crucial for memory consolidation and performance. It's clear that sleep plays a vital role in our cognitive function and overall well-being.
