What are Sleep Disorders?

Sleep disorders encompass a range of conditions that disrupt normal sleeping patterns. These disturbances can affect the duration, quality, and timing of sleep, leading to daytime fatigue, irritability, and impaired functioning.

Types of Sleep Disorders:

Insomnia: Insomnia involves difficulty falling asleep, staying asleep, or experiencing non-restorative sleep despite adequate opportunity for sleep. It can be acute or chronic and may result from stress, anxiety, depression, or underlying medical conditions.

Sleep Apnea: Sleep apnea is characterized by pauses in breathing during sleep, often due to obstruction of the upper airway. This interruption can lead to fragmented sleep, loud snoring, and daytime sleepiness. Untreated sleep apnea can increase the risk of cardiovascular problems and other health issues.

Restless Leg Syndrome (RLS): RLS causes uncomfortable sensations in the legs, typically during periods of rest or inactivity. Individuals with RLS may feel an irresistible urge to move their legs, which can disrupt sleep onset and maintenance.

Narcolepsy: Narcolepsy is a neurological disorder characterized by excessive daytime sleepiness and sudden, uncontrollable episodes of sleep, known as “sleep attacks.” People with narcolepsy may also experience cataplexy, wherein they lose muscle tone during strong emotions.

Parasomnias: Parasomnias encompass abnormal behaviours or experiences during sleep, such as sleepwalking, night terrors, and REM sleep behaviour disorder (RBD). These episodes can be disruptive to both the individual and their sleep partner.

Causes of Sleep Disorders:

Sleep disorders can arise from various factors, including:

  • Stress and Anxiety: Psychological factors can disrupt sleep patterns and contribute to insomnia and other sleep disorders.
  • Medical Conditions: Underlying health issues such as obesity, heart disease, and neurological disorders can increase the risk of sleep disturbances.
  • Lifestyle Factors: Poor sleep hygiene, irregular sleep schedules, excessive caffeine or alcohol consumption, and use of electronic devices before bedtime can all impair sleep quality.
  • Genetics: Some sleep disorders, like narcolepsy and RLS, have genetic components, making certain individuals more susceptible.

Symptoms of Sleep Disorders:

  • Difficulty falling asleep or staying asleep.
  • Excessive daytime sleepiness.
  • Loud snoring and pauses in breathing during sleep.
  • Restless legs or uncomfortable sensations in the legs.
  • Sudden muscle weakness or paralysis during strong emotions (cataplexy).
  • Abnormal behaviours during sleep, such as sleepwalking or night terrors.
