In these times of worry and stress, 24-hour lifestyles, and caffeine to fuel everyday functioning, more and more people are getting less and less sleep. Serious sleep disorders like insomnia and sleep apnea are on the rise, and sleeping pill companies are continually increasing their sales. Most people know the sleep deprivation effects and how uncomfortable it is to be sleep deprived, but what they don’t know is how deadly it can be.

Scientists and researchers have recently conducted studies to find out the physical effects of sleep deprivation. The results are alarming. Research is beginning to reveal a host of major illnesses that can be aggravated, and possibly even caused, by sleep deprivation. Such illnesses include cancer, diabetes, obesity, and heart disease.

This article cannot even begin to reveal every single health problem related to sleep deprivation effects, but an overview of some of the more serious problems is listed below:

Brain Sleep Deprivation. Sleep regenerates the entire body, but the brain especially needs sleep to function properly. When a person is awake for extended periods of time, neurons in the brain start to malfunction and negatively affect the person’s behavior. These neurons cannot be regenerated without going through certain stages of sleep. Not only could this potentially have some damage on the brain, but it causes visible problems in a person’s behavior.

Sleep Apnea Weight Gain. Sleep deprivation disrupts hormones in the body. Some of the hormones it affects are the ones that regulate appetite. A study of 10,000 people shows that people who sleep fewer than seven hours a night are much more likely to be obese.

Cancer Problems. People who don’t sleep enough have higher levels of substances in their blood caused by inflammation in their bodies. This inflammation causes many other diseases as well as cancer, such as stroke and diabetes. Also, people who don’t sleep enough have reduced levels of melatonin, the hormone that tells the body to sleep, and not enough melatonin has been linked to breast cancer. Many other hormones and proteins related to cancers are disrupted by a lack of sleep.

Heart Problems. The inflammation that increases cancer has also been linked to heart disease. Another problem with sleep deprivation is that studies have shown a lack of sleep causes a stressful state of high-alert in the body. When a person is significantly stressed, their body over-produces stress hormones, which drives up the person’s blood pressure. These stress hormones are a huge risk factor in heart attacks.

Diabetes Problems. People who are sleep deprived have problems regulating their blood sugar. Such problems with blood sugar correlates to diabetes, so a significant lack of sleep can cause or increase the risk of diabetes.

Sudden Death Sleep. At Harvard Medical School, Sanjay R. Patel led a study that involved over 82,000 nurses to see what correlations sleep deprivation had with physical and mental problems. Surprisingly, he found an increased rate of death in persons that slept less than six hours each night.

Most people are very familiar with the rules of good health – eating right, exercising, etc. – but scientists are just starting to realize that one of the most important aspects of good health is good sleep and can eliminate or reduce the sleep deprivation effects.

You have probably experienced mild sleep deprivation at one time or another. There have been times when you have not had enough sleep – it happens to everyone. But true sleep deprivation can be a serous condition. Sleep deprivation can lead to a host of different illnesses, including some cancers. There are both physical as well as psychological effects of sleep deprivation.

Sleep Deprivations Studies

Sleep deprivation studies have been conducted on those who have suffered these deprivations on a repeated basis. Many of them have been college students who have purposely prevented themselves from sleeping so that they could study for exams. In college, sleep deprivation is common around the end of terms, but studies are indicating that it is a lot more harmless than just getting a few dark circles under the eyes. There have been indications that students who have routinely deprived themselves of sleep have experienced a host of problems, including episodes of psychosis.

Physical Effects of Sleep Deprivation

Physical effects of sleep deprivation are often apparent. A person who is deprived of sleep feels tired most of the time. They may have dark circles under their eyes. These are the classic physical signs of sleep deprivation of which we have become accustomed. But there are more serious physical consequences to sleep deprivation than just the idea of someone appearing to be tired. Sleep deprivation studies have indicated that a lack of sleep can lead to serious diseases such as diabetes, depression and some cancers. This is due to the disruption in the hormones that take place when the body does not sleep.

Obesity and Sleep Deprivation Health

Obesity is a common side effect of sleep deprivation. Obesity and sleep deprivation seem to go hand in hand as many studies indicate that not only does sleep deprivation lead to obesity due to hormone imbalance created by sleep deprivation, but that obesity can also influence sleep habits. Someone who is obese has more of a chance of getting sleep apnea, a sleeping disorder that causes the individual to awaken several times during the night and is often characterized by snoring.

Other physical effects of sleep deprivation include a delayed reaction time. Someone who is tired and not getting enough sleep will not have the same reaction time as someone who is fully rested. A lack of sleep, therefore, can prove to be harmful if someone is driving a car or operating heavy machinery. Thousands of accidents, many of them fatal, occur each year due to sleep deprivation and a lack of sufficient reaction time.

Sleep Deprivation while Driving

Sleep deprivation while driving occurs more often than people think. Truck drivers, under pressure to get a delivery to a destination within a certain amount of time, will often self deprive themselves of sleep. They take artificial stimulation so that they can stay awake at the wheel for longer periods of time. Despite the fact that this is illegal and dangerous, some trucking companies look the other way when it comes to their drivers taking on more than one shift. Accidents involving truckers who have fallen asleep at the wheel due to sleep deprivation and driving occur all over the United States.

Signs of Sleep Deprivation

In addition to obvious signs of sleep deprivation such as dark circles under they eyes, that indicate a lack of melatonin, someone who is deprived of sleep may also be irritable and appear nervous. Their hands may shake due to an imbalance in the central nervous system that occurs because of sleep deprivation. Anyone who is suffering from sleep deprivation may exhibit these signs.

Sleep Deprivation and Reaction Time is slowed considerably

Sleep deprivation is not only dangerous when it comes to driving, operating heavy machinery or working, but can also lead to a host of physical problems due to the hormonal imbalance that is created when the body is deprived of sleep. If you are not sure if you are getting enough sleep, you should seek out the results of a sleep study. You can do your own sleep tracking study, or you can seek out this type of study at a clinical environment if you feel that you are suffering from sleep deprivation.

Studies may conclude that sleep heat disease with mild sleep deprivation and disrupt hormones ghrelina and leptin.  These hormones regulate appetite, lack up sleep can also aid in colon cancer, breast cancer, heart disease and diabetes.  Medical study found that people who slept less than six ours a night were at an increased risk of death.  The common prescription to treating insomnia are thru drugs; such as, Ambien, Lunesta, and Sonata.  An over the counter drug melatonin is produced synthetically to mimic the natural melatonin producted by the body.

Drowsy driving is like having several alcoholic drinks and drive after works, bottom line, it is very dangerous. It takes the focus and concentration away from the driver, they become a danger to themselves and other drivers.

Sleep and Stress Can Cause Cellular Aging

Studies have found that inadequate sleep in elderly who experience sleep disturbances, could aggreate aging cells like Alzheimer and Parkinson diseases.

Young Mice were used as an experiment to determine effects of sleep deprivation and aging. The experiment was conducted on a 3,6,9, or 12 hours basis of sleep deprivation. On the six hour of sleep deprivation, mice demonstrated the unfolded protein response (UPR) system. The unfolded protein response is part of the quality control system for monitoring protein synthesis in the endoplasmic reticulum, that is the cellular compartment where some proteins are made. Old mice which were not stress by sleep deprivation were shown to already have an impaired UPR.

The results speculate that sleep disturbance in older humans are heavily burden on already stressed protein in the system.

Learning becomes less efficient when sleep deprived, different parts of the brain are activate when verbal learning between (temporal region) rested patients and (parietal lobes) non rested patients. Although brain activity is present in both subject, sleep deprivation memory was less efficient but is associated with better memory.

The NeuroReport found that the brain is extremely dynamic and will try to function when sleep deprived, even when the ability of cognitive task diminishes. Remember that being deprived of sleep has side effects, impeding the brain to function normally.
