Sleep Disorders - Common Types, Causes, Symptoms

What Is Sleep?

Sleep is more than just resting. Even though you are not aware of it while sleeping, your brain and body are still busy working. They do important jobs that keep you healthy and help you feel good. So, if you do not get enough good sleep, it is not just about feeling tired. It can affect your health, your mood, how you think, and how you manage daily tasks.

What Are Sleep Disorders?

Sleep disorder is a problem that makes it hard to sleep or prevents one from having peaceful sleep. This, in turn, can cause daytime sleepiness and other symptoms. A hundred million people of all ages are not getting adequate sleep and are suffering from unwanted consequences in school, college, work performance, and personal relationships.

Sleep disorders can be suspected if:

• A person regularly experiences difficulty sleeping.

• A person is often tired during the day, even though they slept for at least seven hours the night before.

• A person has a reduced ability to perform regular daytime activities.

What Are the Common Types and Symptoms of Sleep Disorders?

The most common types of sleep disorders include:

1. Insomnia - Insomnia is a sleep problem where people struggle to fall asleep and experience symptoms, such as :

• Difficulty in falling asleep.

• Having problems falling back to sleep and frequently getting up during the night.

• Waking up early in the morning.

• Having disturbed sleep.

• It can, in turn, result in muscle fatigue, sleepless nights, inability to focus, accidents, mood swings, and short temper.

2. Sleep apnea - Sleep apnea is a very serious sleep problem that occurs when a person's breathing is interrupted during sleep. Two types of sleep apnea are most common these days, and they are:

• Obstructive sleep apnea or snoring: It occurs when the backside of the throat collapses during sleep. Symptoms include daytime sleepiness, fatigue, restlessness during sleep, and trouble concentrating.

• Central sleep apnea: Central sleep apnea occurs when the brain does not send the signals to breathe for short periods during sleep, affecting how the body works. If a person is asleep, the brain, which regulates breathing cycles, fails to signal the body to breathe. As a result, people with this disorder mostly report recurrent awakenings during the night.

3. Restless leg syndrome: A sleep disorder that causes a severe, sometimes irresistible urge to move the legs. It is generally seen during resting, such as lying down in bed and sitting for prolonged periods while driving or at the theater. It typically occurs in the evening, and people tend to walk around or shake their legs to help relieve the uncomfortable sensation.

4. Narcolepsy: Narcolepsy is a health problem where people actually feel very sleepy during the day and sometimes fall asleep suddenly without even realizing it. Some patients suddenly fall asleep during any activity, which sometimes becomes risky. It is commonly seen in people around the age of 15 to 25 years.

What Are the Causes and Risk Factors of Sleep Disorders?

There are different things that can increase the chances of having sleep disorders:

• Age: As people start aging, their sleep patterns change. For example, children have issues like bed-wetting, while older adults are more likely to face sleep problems.

• Family history: If anybody in your family has a sleep problem like insomnia, sleepwalking, restless legs, or sleep apnea, then there are chances that you can have them too because it is a genetic problem as well.

• Health problems: Conditions like Parkinson’s (a movement and coordination disorder), multiple sclerosis (nervous system damage), or brain injuries can cause sleep troubles. Diseases like heart problems, lung issues, cancer, diabetes, or chronic pain are often linked to insomnia. Being overweight causes sleep apnea, and heart problems can raise the risk of another type of sleep apnea.

• Mental health: Stress, depression, and anxiety can make it hard to sleep well.

• Changes in schedule: Traveling across time zones or working night shifts can mess up your body’s natural sleep rhythm.

• Medications and substances: Some medicines, caffeine, alcohol, and even street drugs can interfere with sleep.

What Is the Impact of Sleep Disorders?

Sleep disorders can affect life in many ways, not just by making one feel tired. Inadequate sleep can make it hard for you to focus, think clearly, or remember things during the day. It can also make a person feel moody, stressed, or more easily irritated.

Over time, not getting good sleep can cause some major health problems like high blood pressure, heart disease, diabetes, and even obesity. It can also weaken the immune system, making it easier to get sick. Sleep problems do not just affect physical health; they can also harm mental health. People with sleep disorders are more likely to feel anxious or depressed.

How to Diagnose Sleep Disorders?

A healthcare provider diagnoses sleep disorders by taking a complete history and sleep schedule and assessing whether the patient can fall asleep. The doctor can also do a physical or medical examination, as some illnesses can cause disturbed sleep. In addition, the doctor may take a blood sample to check for thyroid illness, low iron levels, or other disorders that may cause sleep issues.

Polysomnography, a sleep study or comprehensive examination, is used to detect sleep problems. The heart rate, breathing, blood oxygen levels, eye and leg movements, and brain waves are all monitored during this test. The doctor can also detect insomnia, sleep apnea, and other sleep issues by using a small device called an actigraphy monitor.

How to Treat Sleep Disorders?

A healthcare provider can help treat sleep problems and suggest the best treatments depending on each person’s specific situation.

• Some sleep specialists recommend cognitive behavioral therapy, such as counseling, which helps a person to recognize, challenge, and change stress-induced thoughts that can keep a person awake at night.

• Minimize light.

• Medications and supplements: In a few cases of insomnia, including Zolpidem, Melatonin, Eszopiclone, Zaleplon, Ramelteon, or Doxepin can be helpful. Restless leg syndrome is treated with Gabapentin or sedatives.

• Follow a proper sleep schedule, which should be at least eight hours daily.

• Minimize noise.

• Get regular exercise.

How to Get a Good Night's Sleep?

• Create a calm and optimal sleep environment.

• Think positive.

• Try to meditate and clean the bed before going to bed.

• Fix a proper time for going to bed, and do not disturb the sleeping hours.

• Avoid the intake of alcohol and tobacco.

• Do regular exercise.

Sleep disorders are common problems that disrupt sleep quality and affect daily life, mood, and health. Common types include insomnia, sleep apnea, restless leg syndrome, and narcolepsy.
