Understand Sleep Disorder

Pulmonology | Posted on 05/12/2020 by RBH

Sleep is a very critical part of your everyday routine. An adult above the age of 18 must get 7 to 9 hours of sleep, while for ages 13-18 the hours of sleep shouldn’t be less than 9.25, and for ages 5 to 12 years it should be at least 10-11 hours. Getting quality sleep at the right time and in the right amount is very necessary to ensure a healthy and active body. It is as essential as water and food for the body because without sleep the pathways in the brain cannot be maintained, which are responsible for learning and creating new memories. Moreover, lack of sleep makes it harder to concentrate and respond quickly.

Sleep is also very vital for many brain functions such as communication of nerve cells with each other, and the removal of toxins from the brain. Sleep affects all organs of the body including the brain, heart, immunity, metabolism, etc. Lack of quality sleep increases the risk of various health problems such as blood pressure, heart problems, diabetes, depression, as well as obesity. Hence, it is very crucial to understand that quality sleep is a body’s requirement and not a luxury. So, any sleep disorders need to be handled with the same criticality as any other health disorder.

Types of sleep disorders

Some broad categories of common sleep disorders are:

Sleep Apnea: In this disorder, the normal breathing of a person is interrupted during sleep. These can further be classified into two broad categories – Obstructive sleep apnea which is caused because of blockage in the airways; and Central sleep apnea which results because the brain fails to signal the muscles to breathe. Sleep apnea is often categorised by snoring, sleepiness during the day, fatigue, restlessness, sudden awakenings, gasping or choking at night, dry mouth, sore throat, night sweats, headaches, etc.

Insomnia: The most common type of sleep disorder in which a person experiences difficulty in falling asleep, staying asleep, as well as does not feel refreshed post sleeping, in spite of being a setting that is appropriate for sleeping.These are further of two types – Primary insomnia which occurs independently of other health problems; and Comorbid insomnia which happens because of pain, medication, drugs, alcohol, etc. Insomnia symptoms include unexplained tiredness, fatigue, low mood, irritability, and a problem in concentrating.

Restless Leg Syndrome (RLS): In this disorder, there is a severe and irresistible urge to move legs.It happens because of sitting or lying down for a long period of time. The symptoms include the urge to move legs along with a tingling, pulling and uncomfortable sensation.

Circadian Rhythm Disorders: This type of disorder is characterized by disruptions in the internal body clock which is responsible for the biological processes in the body and functions per 24 hours. Disorders such as delayed sleep, jet lag, advanced sleep, shift work, etc. are all caused because of interruption in the body clock.

Parasomnias: These disorders involve undesirable, abnormal or abrupt behaviours that occur while going to sleep, during sleep, or when aroused from sleep. These may occur during rapid eye movement (REM) or non-rapid eye movement (NREM) sleep. A person suffering from parasomnias nightmares, sleep terrors, sleepwalking, confusional arousals, sleep eating, bedwetting, etc.

Narcolepsy: A neurological disorder that happens because of the reduction of a brain component that regulates the sleep-wake cycle. People suffering from narcolepsy experience extreme sleepiness during the day and uncontrollable episodes of sleeping during the day in spite of having slept adequately.

Symptoms of Sleep Disorders

Sleep disorders can be of multiple types and hence, the symptoms for each depend on the condition and cause of the disorder. However, some general sleep disorder symptoms include:

  • Consistently not being able to fall asleep at least for 30 minutes post-bedtime
  • Disturbed sleep with intervals of awakening at night
  • Rising abruptly during peak morning hours

Treatment of sleep disorders depends on case-to-case and the type of disorder one is experiencing. However, some general steps that contribute towards a healthy and undisturbed sleep are:

  • Good sleeping habits such as routine bedtime, positive sleep environment, avoid daytime naps, etc.
  • Healthy lifestyle and diet habits such as low caffeine, less alcohol, more green vegetables, balanced carbs, regular exercising, etc.
  • Reduce exposure to electronics including laptops, mobile phones, etc. especially 2 hours before bedtime.
  • Cognitive behavioural therapies, meditation or other relaxation techniques to reduce anxiety
