One can physically go 264 hours, or 11 days, without sleep (Everston). However, sleep is an extremely important part of everyone’s lives. On average, a teenager is recommended at least 8 to 9 hours, and an adult, 7 hours of sleep at night (Tuck). A sleeping disorder, on the other hand, drastically changes the way in which one sleeps. It can affect overall health, safety, and one’s own quality of life and can be a significant burden on one’s life. There are over 100 different types of sleep disorders and the three most dangerous disorders include insomnia, narcolepsy, and REM – Sleep Behavior Disorder. Insomnia is the very most common sleep disorder, including both sleep disturbance and daytime symptoms (Health Line). The effects of insomnia can change one’s every aspect of life. With that being said, it can affect one’s work performance, relationships, and even one’s decision making. Insomnia increases with one’s age as well (Health Line). It can increase one’s overall health concerns, such as medical conditions, mental health disorders, and shorten one’s life expectancy (Health Line). It can occur at any age in men or women, but mostly common in women. There are various kinds of insomnia: acute, chronic, transient, and several different subtypes. Acute is a moderate time period of insomnia. Those with acute insomnia have experienced sleeping difficulties such as inability to fall asleep or stay asleep for less than one month (Mental Health Daily). If the sleep difficulties persist for longer than a month, an individual would be diagnosed with “chronic” insomnia. Individuals with chronic insomnia are considered to have the condition for longer than one month. Finally, the third primary type of insomnia is transient meaning temporary. Transient is often untreated because it lasts within one week (Mental Health Daily). Insomnia can be caused by medical conditions, unhealthy sleep habits, specific substances, and/or certain biological factors (Mental Health Daily). There are various medical conditions that could lead to insomnia, such as: asthma, arthritis, chronic pains, neurological conditions, etc (Sleep Foundation). Taking certain medications can also cause insomnia. Not to mention, one’s concerns on work, school, family issues, etc, can cause stress, leaving one’s mind very active at night keeping them awake. Under those circumstances, insomnia can excessively change one’s life.Narcolepsy is a very dangerous sleep disorder that affects the control of sleep and wakefulness. Narcolepsy can affect one’s daily life by causing oneself to become lethargic or fall asleep at any given moment. One with narcolepsy will feel very tired throughout the day and could involuntarily fall asleep during normal, daily activities (Sleep Foundation). In other words, the normal boundary between awake and asleep is entirely blurred as the tiredness and lethargy of sleeping can occur while one is awake (Sleep Foundation). Narcolepsy occurs equally in men and women and affects around 1 in 2,000 people, occuring between the ages 15 and 25 (Sleep Foundation). There are various symptoms of narcolepsy including excessive daytime sleepiness, cataplexy, hallucinations, and sleep paralysis. Excessive daytime sleepiness is a main symptom. It interferes with one’s daily activities, whether or not one with narcolepsy has sufficient sleep at night. Cataplexy, in other words, is a medical condition in which any type of strong emotion or laughter causes one to suffer a sudden physical collapse (WebMD). Generally speaking, narcolepsy could occur at any time to anyone at any moment. Currently there is no cure for narcolepsy, but medications and behavioral treatments can improve symptoms for people so they can lead normal, productive lives (Sleep Education). The most effective treatment is normally a combination of medications, behavioral changes, and therapy; the behavioral changes would include maintaining a regular sleep schedule, avoiding heavy meals and alcohol, exercising regularly, scheduling naps, etc (WebMD). Rapid Eye Movement Sleep Behavior Disorder is a parasomnia in which one physically acts out vivid, unpleasant dreams with vocal sounds and violent arm and leg movements during REM sleep — sometimes called dream-enacting behavior (Sleep Education). REM occurs when one acts out vivid dreams as one sleeps. These recurrences are quite often filled with action and even a chance of violence (Sleep Education). The episodes gradually get worse over time. It is very likely to end in an injury to either one’s bed partner or oneself. With REM sleep behavior disorder, instead of experiencing the normal temporary paralysis of one’s arms and legs, during REM sleep, one will physically act out one’s dreams (Mayo Clinic). It could be gradual and or sudden. The episodes could occur several times in just one night. Symptoms would include extreme movement such as kicking, jumping, punching etc, also screaming and laughing, and most importantly, being able to recall the dream if you awaken during the episode (ED Medicine). There is an assorted amount of risk factors for developing REM. Being male and more commonly over 50 years old, although more women nowadays, are being diagnosed with this disorder (Mayo Clinic). Having narcolepsy and taking certain medications especially antidepressants can be a large risk factor (Mayo Clinic). Less than 1% of the world have it and is often taken care of through nothing but medications. In addition to insomnia, narcolepsy, and REM Sleep Disorder being unhealthy, there are medications but minimal treatments for each disorder. Ignoring sleep disorders can lead to poor health and mood, lethargy, and may negatively impact motivation, relationships, and job performance. To explain, an individual going 11 days without sleep, is extremely unhealthy for oneself and life threatening. It is important to know these unhealthy sleep disorders because otherwise it could be a prominent problem in today’s society.
