The Top 7 Dangers of Sleep Deprivation

Sleep is essential for a waking life filled with energy, and good health. This is a fact proven by science and one you have probably noticed in your own life; especially if you have ever experienced the effects of sleep deprivation.

Valley Sleep Center Blog: The Top 7 Dangers of Sleep Deprivation

Everyone knows that lack of sleep can make a person grumpy and foggy. However, not everyone knows that sleep deprivation can significantly affect your health, safety, and performance.

These Are the Top Seven Dangers of Sleep Deprivation:

 

  1. Sleep Deprivation Affects How You Learn

Sleep plays a vital role in how you learn and think. Lack of sleep impairs your attention span, alertness, reasoning, concentration, and ability to problem solve. This makes it difficult to learn effectively. Also, when you sleep at night, you go through various sleep cycles that play a role in strengthening your memories. When you don’t get enough sleep, you are less likely to remember what you experienced or learned that day.

  1. Sleep Deprivation Can Lead to Accidents

Were you aware that sleep deprivation played a role in some of the biggest disasters in the last 40 or so years? To name a few; the 1979 nuclear accident at Three Mile Island, the Exxon Valdez oil spill, and the nuclear meltdown at Chernobyl in 1986. However, sleep deprivation is its most dangerous to us as a public every day out on the road. Driving drowsy can slow your reaction time as much as drunk or impaired driving would. According to the National Highway Traffic Safety Administration (NHTSA), sleep deprivation, or drowsy driving is a cause in around 100,000 auto crashes and 1,500 crash-related deaths yearly in the U.S. Statistics show that the problem is greatest among people under 25 years old. Sleep deprivation or poor-quality sleep is also known to lead to accidents and/or injuries in the workplace.

  1. Sleep Deprivation Can Have Serious Effects on Your Health

It is estimated that around 90 percent of people who suffer from insomnia -a sleep disorder characterized by difficulties falling and staying asleep-  also suffer from other medical conditions. According to WebMD, chronic sleep deprivation could potentially lead to:

  1. Sleep Deprivation is Linked to Depression

For some, depression causes sleep deprivation, and for others sleep deprivation can cause depression. A Sleep in America poll conducted in 2005 concluded that people who were diagnosed with depression or anxiety were more likely to get less than six hours of sleep at night. Of all sleep disorders, insomnia has the strongest link to depression. In a sense, insomnia and depression feed off of each other.

  1. Sleep Deprivation Can Make You Forgetful

Getting plenty of sleep helps keep your memory sharp. According to WebMD, in 2009, American and French researchers determined that brain events called “sharp wave ripples” are responsible for consolidating memory. The ripples also transfer learned information from the hippocampus to the neocortex of the brain, where long-term memories are stored. Sharp wave ripples occur mostly during the deepest levels of sleep.

  1. Sleep Deprivation Can Cause Weight Gain

It has been proven that a lack of sleep is related to an increase in hunger and appetite, and possibly even obesity. WebMD sites that a 2004 study claimed that people who sleep less than six hours at night were nearly 30 percent more likely to become obese than those who slept seven to nine hours. Sleep loss is also linked to cravings for foods that are high-fat and high-carbohydrate. Studies are being done to help determine whether or not adequate sleep should be a part of weight loss programs.

  1. Sleep Deprivation Could Increase the Risk of Death

According WebMD, in the “Whitehall II Study,” British researchers looked at how sleep patterns affected the mortality of more than 10,000 British civil servants over two decades. The results, published in 2007, showed that those who had cut their sleep from seven to five hours or fewer a night nearly doubled their risk of death from all causes. In particular, lack of sleep doubled the risk of death from cardiovascular disease.

If you are suffering from sleep deprivation, it is important to note that it is commonly due to unrecognized sleep disorders. If after a typical night’s sleep, you don’t feel restored and refreshed and are sleepy during the day, you may benefit from a sleep study.  A sleep study is a stepping stone to helping you get the sleep you need to better maintain your health and well-being.

"Great staff, they make you feel so at home. Every medical facility should be this nice. Felt like a nice hotel. Someone has great taste in decorating. Thanks for making us feel at home."

"I was especially impressed with Andrew the Respiratory Therapist who reviewed my study with me and answered my questions. Andrew thoroughly explained everything about the Cpap machine-from start to finish. I never felt rushed and was assured I could contact him with any additional questions or needs. Andrew told me he would follow up with a call in a week and he did. I believe this center performed the study appropriately and the added benefit of having Andrew teach me about the machine and what to expect was a bonus."

"I recommend them highly!! I took my 2 year old daughter for a sleep study and was very impressed. Our sleep technician was amazing with her, very patient and kind. The DVD we brought to watch while getting her hooked up got stuck in the TV and they vowed to return it. We got a call the next day checking on our daughter and saying how sweet she was, they mentioned the DVD. Several days later, we received the DVD plus a new copy of the Lion King with a nice note. They are very good at what they do and if they can make a 2 year old feel at ease, they can probably do the same with anyone!!"
