Most common sleep disorders

February 15, 2022by Oliver0

Sleep disorder is any condition that disrupts the way you fall and stay asleep. You may snore or stop breathing in your sleep, or you might feel tired after sleeping for many hours. Sleep disorders can leave you feeling fatigued during the day no matter how long you spend sleeping at night. Some common types of sleep disorders include:

  • Insomnia (inability to fall asleep or stay asleep)
  • Obstructive sleep apnea (breathing stops during sleep due to obstructed airways)
  • Restless legs syndrome (uncomfortable tingling, burning, pulling, etc. in your legs while resting)

What are sleep disorders?

Sleep problems affect the amount, quality, and timing of sleep, causing daytime pain and impairment in functioning. Sleep disorders are commonly associated with medical illnesses or mental health concerns including depression, anxiety, or cognitive impairments. Insomnia is the most common sleep disorder. Sleep disorders include obstructive sleep apnea, parasomnias, narcolepsy, and restless legs syndrome.

Sleep disorders have been linked to both physical and mental concerns. According to the National Sleep Foundation, sleep disorders may cause or aggravate mental health issues, and they can also be an indication of other mental diseases.

How much sleep is necessary?

Getting enough sleep

Sleep is a basic human necessity for both physical and mental health. Also, pay attention to your sleeping patterns. Your body has a 24-hour cycle that helps you decide when to sleep and get up.

The quantity of sleep we need varies with age and individuality. According to the National Sleep Foundation, most people need between 7 and 9 hours of restorative sleep every night. After reviewing the scientific literature, the Foundation updated its sleep recommendations some years ago.

Many of us do not get enough sleep. According to the National Sleep Foundation, about 30% of adults get less than six hours of sleep every night, while just 30% of high school students get at least eight hours. 2 Sleeping circumstances are described as “poor” or “only fair.” by the majority of Americans (about 35% of

Sleep is essential for brain health. Insufficient or poor-quality sleep has several harmful consequences. The most common symptoms are weariness, low energy, irritability, and trouble focusing. This disorder may affect your judgment and emotions. Sleep difficulties often develop in connection with melancholy or worry. Sleep difficulties may increase sadness or anxiety, and vice versa.

Sleep deprivation and excessive sleep are linked to chronic health issues including heart disease and diabetes. Sleep difficulties may signal medical and neurological illnesses such as congestive heart failure, osteoarthritis, and Parkinson’s.

Types of sleep disorders are there

In most cases, people who suffer from sleep disorders have difficulty sleeping and/or staying asleep, as well as waking up in the early morning hours.

Insomnia, sleep apnea, restless leg syndrome, and narcolepsy are just a few of the many types of sleeping disorders that can affect people.

Having difficulty sleeping or remaining asleep for at least 3 nights per week for a period of at least 3 months is considered to be insomnia.

Sleep apnea is defined as a temporary cessation of breathing during sleep that lasts for 10 seconds or more and occurs several times during the course of a night’s sleep.

When you have Restless Leg Syndrome, you have an irresistible urge to move your legs even when you are lying down.

Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness that typically begins with symptoms such as extreme fatigue and sudden muscle weakness during the day and is followed by nighttime sleepiness and grogginess.

Restless legs syndrome

restless legs syndrome rls

Restless legs syndrome (RLS) is characterized by an uncontrollable need to move your legs. It usually happens late at night when sitting or lying down. Moving around temporarily relieves the discomfort.

Restless legs syndrome, also known as Willis-Ekbom disease, may strike at any age, and it frequently worsens with age. It may induce sleep disorders, affecting daily activities. Simple self-care and dietary changes may help relieve symptoms. Medication helps many RLS sufferers. To move one’s legs is the main symptom.

Frequent symptoms of RLS:

  • After a time of relaxation, sensations arise. Long periods of time lying or sitting, like in a car, plane, or movie theater, frequently cause discomfort.
  • Moving brings relief. Stretching, jiggling your legs, pacing, or walking may help relieve RLS symptoms.
  • Evening symptoms worsen. The bulk of symptoms occurs at night.
  • Leg twitching all night. RLS may be linked to a more common condition called periodic limb movement sleep, which causes legs to twitch and kick throughout the night, perhaps all night.
  • RLS symptoms are often characterized as odd, achy sensations in the legs or feet. They often affect both sides of the body at once. The emotions may also be felt in the arms, although this is rare.

It is possible to characterize the feelings, which often occur inside the limb rather than on the skin, as follows:

  • Crawling
  • Creeping
  • Pulling
  • Throbbing
  • Aching
  • Itching
  • Electric

It might be tough to put into words what you are feeling. Individuals who suffer from RLS do not often characterize the illness as a muscle spasm or numbness. They do, on the other hand, constantly express a desire to get their legs moving.

It is usual for symptoms to change in intensity over time. In other cases, symptoms may vanish for a period of time before reappearing.

Circadian rhythm disorders

Sleeping disorders occur when your sleep cycle is not in sync with your environment.

The biological clock in your body governs numerous activities and processes, including when you sleep and wake up. This biological mechanism is called the circadian clock. It is a 24-hour cycle for the human body. These 24-hour cycles are called circadian rhythms. Circadian clock genes in your DNA influence how you feel throughout the day and night.

Healthy sleep cycles are synchronized with environmental cues such as light and dark, food intake, and physical activity. If your sleep cycle is out of whack with your circumstances, you may have difficulty sleeping or sleep poorly. Circadian rhythm disorders cause sleep cycle disturbances that interfere with daily activities.

Disruptions in sleep patterns may be induced by external factors such as sleeping habits, work schedules, or vacation plans. The issue may be long-term and caused by internal variables including age, genetics, or a medical condition. This syndrome may cause extreme daytime sleepiness, insomnia, fatigue, low attentiveness, memory, and decision-making difficulties.

A doctor may enquire about your sleep patterns, prescribe sleep tests, a sleep diary to document when and how long you sleep, and test hormone levels in your blood or saliva to diagnose a circadian rhythm issue. Your doctor may prescribe sleep medication if you have a circadian rhythm disorder. The kind and cause of your circadian rhythm issue will dictate your treatment plan. Insomnia may be treated with light therapy, drugs that help you fall asleep or stay awake, and healthy lifestyle modifications including improving your sleep habits. Untreated clock-related disorders may increase the risk of various health issues, as well as employment and traffic accidents.

Sleep apnea

Snoring is a potentially dangerous sleeping problem in which the patient’s breathing regularly stops and begins during sleep. If you snore loudly and wake up feeling fatigued even after a full night’s sleep, you may be suffering from sleep apnea, which is a medical condition.

The following are the most common kinds of sleep apnea:

  • Obstructive sleep apnea is the more prevalent kind of sleep apnea, which happens when the muscles in the throat relax during sleep.
  • Central sleep apnea is a condition in which your brain fails to deliver correct signals to the muscles that regulate your breathing while you sleep.
  • Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, is a condition in which a person has both obstructive sleep apnea and central sleep apnea at the same time.

Symptoms of sleep apnea:

It may be difficult to distinguish between obstructive and central sleep apneas since the signs and symptoms of both types are similar, making it tough to establish which kind you have. The following are the most prevalent signs and symptoms of both obstructive and central sleep apneas:

  • Snoring that is audible
  • Episodes in which you stop breathing during sleep — which might be seen by another person — are classified as sleep paralysis.
  • While sleeping, you may find yourself gasping for oxygen.
  • Having a dry tongue when you first wake up
  • Headache in the morning
  • Having trouble falling asleep (insomnia)
  • Excessive drowsiness throughout the day (hypersomnia)
  • While awake, it is difficult to pay attention.
  • Irritability


It is a persistent sleep disorder characterized by excessive daytime drowsiness and falling asleep suddenly. Narcolepsy patients generally struggle to stay awake for long periods of time, regardless of the environment. Narcolepsy may cause major disruptions in your daily routine.

Cataplexy is a sudden loss of muscle tone that may occur with narcolepsy and be triggered by strong emotions. Type 1 narcolepsy is caused by cataplexy. Type 2 narcolepsy occurs without cataplexy.

Nausea and tiredness are symptoms of narcolepsy, a chronic condition with no cure. Medication and lifestyle changes may help manage symptoms. The help of others may be quite helpful in managing narcolepsy.


  • Throughout the day drowsiness. Narcoleptics fall asleep without warning, at any time and anywhere. You may be working or talking with pals when you abruptly fall asleep for a few minutes to a half-hour. You feel energized when you initially wake up, but then weary.
  • Throughout the day, you may notice a loss of focus and concentration. The initial symptom is usually extreme daytime sleepiness, which makes it difficult to concentrate and do everyday duties.
  • Muscle tone drops abruptly. This illness, which is pronounced cat-uh-plek-see, may cause various bodily changes. These alterations might last a few minutes or longer and vary from slurred speech to complete muscular weakness.
  • The uncontrollable response to intense emotions such as laughter or excitement, although it may also be caused by emotions such as fear, surprise, or fury. Depending on the scenario, your head may droop or your knees may fall as you laugh.
  • According to the National Narcolepsy Society, some narcoleptics have cataplexy just once or twice a year, while others experience it frequently. Not all narcoleptics have cataplexy.
  • Sleep paralysis happens while the body is sleeping. Narcoleptics typically experience a short inability to move or speak when they fall or wake up. Even though these episodes are brief (a few seconds or minutes), they may be frightening. In other circumstances, you may be aware of your situation and recall it afterward, even though you had no control over it.
  • This sleep paralysis is comparable to the transient paralysis that occurs naturally during REM sleep, which is a kind of deep sleep. This temporary immobility during REM sleep may prohibit your body from carrying out your dream activities.
  • But not everyone with sleep paralysis has narcolepsy. Sleep paralysis occurs in many people, even those without narcolepsy.
  • Changes in REM sleep are seen. REM sleep is when most dreams occur. Patients with narcolepsy may have REM sleep at any time of day or night. Narcoleptics enter REM sleep quickly, usually within 15 minutes after falling asleep.
  • Hallucinations. These hallucinations are referred to as hypnagogic hallucinations or hypnopompic hallucinations depending on when they occur. For example, you may feel a stranger in your room. Because you may not be fully asleep when you start dreaming, your hallucinations may be quite vivid and frightening.

Periodic limb movements of sleep

Leg cramps or jerks may occur while sleeping. Periodic limb movement disorder (PLMD). It is the only movement disorder that occurs solely during sleep, and some specialists call it periodic leg (or limb) motions. Periodic movements are periodic and rhythmic motions that occur every 20-40 seconds. The movements commonly disrupt sleep and cause excessive daytime weariness, hence PLMD is classed as a sleep condition.

PLMD may occur with other sleep disorders. It is often mistaken with restless legs syndrome, however, they are not the same. Restless legs syndrome causes strange sensations in the legs (and sometimes the arms). The condition causes an irresistible need to exercise the limbs to relieve discomfort. PLMD affects at least 80% of people with RLS, but not the other way around.

When PPMD was first described in the 1950s, it was called nocturnal myoclonus. Myoclonus is a quick, rhythmic contraction of a muscle group, similar to a seizure. Nocturnal implies nighttime, and myoclonus means all night. However, PLMD movements are not myoclonic, therefore the word “myoclonus” is obsolete.

PLMD may strike at any age. Like many other sleep disorders, PLMD is more common in middle-aged and older people.

Seasonal affective disorder

Winter depression, also known as seasonal affective disorder (SAD), is a kind of sadness that is linked to seasonal variations – SAD starts and finishes at about the same period every year. Your symptoms, if you are like the majority of individuals who suffer from SAD, will begin in the autumn and extend throughout the winter months, draining your energy and making you feel depressed. During the spring and summer months, these symptoms are more likely to subside. SAD, which occurs less often, produces depression in the spring or early summer and subsides throughout the autumn or winter months, respectively.

Severe depressive disorder (SAD) is treated with light treatment (phototherapy), psychotherapy, and medicines.

Never dismiss that annual sensation as a simple case of the “winter blues” or a seasonally debilitating malaise that you must endure on your own. Take measures to maintain a consistent attitude and level of motivation throughout the year.


A parasomnia is a kind of sleep disorder characterized by the occurrence of strange and uncomfortable bodily occurrences or sensations that cause you to lose your sleep. A parasomnia is a sleep disorder that may occur before, during, or after waking from sleep. If you suffer from parasomnia, you may have odd movements, speak, express emotions, or do weird things while you are sleeping. You are really sleeping, despite the fact that your bed companion may believe you are awake.

Sleep paralysis

Awake yet unable to move, sleep paralysis is a common condition. An individual passes from one state of wakefulness to another stage of sleep. During these shifts, you may be unable to move or speak for a few seconds to many minutes. Some may also feel pressure or choking. Sleep paralysis is also linked to narcolepsy. Narcolepsy is defined by an overwhelming need to sleep induced by a brain malfunctioning sleep regulation.

Chronic fatigue syndrome

Chronic fatigue syndrome (CFS) is a difficult ailment defined by chronic exhaustion that lasts for at least six months and that cannot be completely explained by an underlying medical condition. It affects around 500,000 people worldwide. The exhaustion develops as a result of physical or mental exertion, but it does not lessen as a result of resting.

Other distinguishing signs and symptoms are as follows:

Nourishing sleep is difficult to come by.

Disabilities in the areas of memory, attention, and concentration

Dizziness that develops when you get up from a laying down or sitting position to a standing position

This disorder is also referred to as myalgic encephalomyelitis in certain circles (ME). ME/CFS is a common abbreviation for this condition. In recent years, the name “systemic exertional intolerance disease” has been suggested (SEID).

Despite the fact that the exact etiology of chronic fatigue syndrome is unclear, there are several ideas that range from viral infections to psychological stress. Chronic fatigue syndrome, according to some experts, may be caused by a variety of elements that come together.

In order to confirm a diagnosis of chronic fatigue syndrome, there is no one test that can be performed. You may need a number of medical tests to rule out other health disorders that exhibit symptoms that are similar to yours. The goal of treatment for chronic fatigue syndrome is to alleviate its symptoms.


Insomnia is common, causing difficulty falling and staying asleep, as well as waking up too early and being unable to go back asleep. You may still feel tired when you wake up. Insomnia may cause loss of energy, mood, health, work performance, and general quality of life.

The length of sleep necessary varies, but most people need seven to eight hours each night.

Many people have acute (short-term) sleeplessness for days or even weeks at a time. Stress or a traumatic event in one’s life usually causes it. Some people, however, have persistent insomnia that lasts a month or longer. Insomnia may be caused by a variety of medical conditions or medicines.

Circadian rhythm disorders

sleep disorder

Circadian rhythm sleep disorders are a category of sleep disorders that are all characterized by a change in the time when people sleep. In Latin, the term “circadian” refers to “around or approximately” (circa) “a day” (diem). The term “circadian rhythm” refers to the 24-hour “internal clock” that exists inside your body. The sleep-wake cycle of your body is controlled by your internal clock.

Lighting serves as a visual signal to “set your internal clock” during the course of a 24-hour day – particularly, the brightness/type of light, length of time spent in the presence of light, and when one is exposed to light. In your brain, light is transported via your eyes and into a specialized “control center” that is responsible for processing information. Other factors, such as melatonin (a hormone secreted in your brain that plays a role in sleep), physical exercise, and social behaviors, might have an impact on your body’s internal clock as well. It is also possible that your age has an impact on how sensitive you are to the sleep-wake cycle.

Circadian rhythm sleep disorders are characterized by one or more of the following problems:

  • You have a tough time getting to sleep at night.
  • You have difficulty sleeping and often wake up numerous times throughout the course of a sleep cycle.
  • You have woken up too early and are unable to get back asleep.


Fybromyalgia (fibro-my-al-gi-a) is a chronic disorder that produces widespread pain throughout the body (also known as widespread pain syndrome), as well as exhaustion, and emotional and mental discomfort. People who suffer from fibromyalgia may be more sensitive to pain than those who do not suffer from the condition. Pain perception processing that is aberrant is referred to as abnormal pain perception processing. Fibromyalgia affects around 4 million individuals in the United States, accounting for approximately 2 percent of the adult population. Although the exact etiology of fibromyalgia is unknown, it is possible to cure and manage the condition efficiently.


What is Rem's sleep behavior disorder?

Rem Sleep Behavior Disorder (RSBD) is a rare disorder that causes people to act out their dreams while sleeping. RSBD can cause an individual to act out violent dreams or frightening dreams with physical consequences such as choking, gasping for air, and even heart failure.

What are the 3 most common sleep disorders?

1. Sleep Disorders Insomnia, or inability to fall or stay asleep. It includes people who can not fall asleep, wake up frequently and can not fall back asleep, wake up earlier than desired in the morning, or simply have insufficient sleep. These issues often manifest as fatigue, irritability, and difficulty concentrating. Around one in ten adults suffers from chronic insomnia, and half of all adults have at least one isolated episode. Chronic insomnia treatments vary depending on the severity and individual circumstances, but the National Sleep Foundation has a good list. Narcolepsy is a disorder that affects sleep control. Narcoleptics may fall asleep unexpectedly during the day and are tired even when awake. Narcolepsy can affect muscle and nerve impulses. Narcolepsy is sometimes linked to insomnia, but not always. 2. Apnea Sleep apnea is characterized by frequent pauses in breathing during sleep. Obstructive sleep apnea (OSA) and central (CSA). The most common form of the disorder is obstructive sleep apnea, caused by a blockage of the throat muscles. OSA is characterized by loud snoring and daytime fatigue similar to insomnia. Central sleep apnea occurs when the brain fails to properly alert the muscles to keep breathing. Awakenings during the night are more common in CSA. Complex sleep apnea syndrome occurs when someone has both OSA and CSA. These disorders require medical attention in severe cases. 3. RLS RLS is characterized by an insatiable urge to shake or move the legs. RLS affects many people, not just those who have trouble sleeping, but it tends to flare up during long periods of stillness, especially sleep. Like insomnia and sleep apnea, RLS causes daytime fatigue, grumpiness, and difficulty concentrating. Most people treat mild RLS at home with stretching, massage, ice or heat packs, but severe cases may require medical attention.

What are the 7 sleeping disorders?

There are several types of sleep disorders that can affect one or both eyes, the ears, the teeth and jaw, the throat, the nose and sinuses, the skin, or other parts of the body. Eye disorders are the most common type of sleep disorder.

The seven most common sleeping disorders:

Insomnia hypersomnia narcolepsy sleep apnea restless leg syndrome periodic limb movement disorder Circadian rhythm disorder

What is the most common sleep problem?

Sleep disruptions are a common health issue that affects millions of people every year. Insomnia, sleep apnea, and narcolepsy are just a handful of the more common sleep disorders. Insomnia is one of the most common sleep disorders and one of the most difficult to treat. Insomnia is the inability to fall or remain asleep for more than 30 minutes at a time. Insomnia may cause daytime tiredness as well as poor quality restful sleep during the night. The most common symptom of insomnia is difficulty sleeping. As a consequence, people with this condition may have trouble falling asleep. It may also be induced by bodily issues like pain or discomfort after an illness or surgery, or a mix of factors including stress and anxiety.

What are 2 common sleep disorders?

Sleep issues impact individuals of all ages, genders, and ethnicities. Here we will look at two prevalent sleep problems and their consequences on people. Insomnia Insomnia is a condition in which you have trouble sleeping or staying asleep. Symptoms include daytime weariness, mood swings, impatience, and difficulties focusing. Narcolepsy When narcolepsy patients are in deep slumber or about to fall asleep, they become hyperalert. Stress, lack of exercise, or too much coffee may cause this disease.

What is the most common sleep disorder?

To put it another way, sleep disorders are common medical conditions that may negatively affect one's overall health and quality of life. Insomnia affects roughly 30% of people in both countries, according to the National Sleep Foundation. You may have this issue if you have trouble falling or staying asleep for longer than 30 minutes. Stress, anxiety, despair, pain or discomfort, painkillers and other medicines, external noise (like traffic) and other underlying medical conditions have all been linked to insomnia.
