Causes

More than 100 different disorders of sleeping and waking have been identified. They can be grouped in four main categories:

  • Problems with falling and staying asleep
  • Problems with staying awake
  • Problems with sticking to a regular sleep schedule
  • Sleep-disruptive behaviors

PROBLEMS WITH FALLING AND STAYING ASLEEP

Insomnia includes any combination of difficulty with falling asleep, staying asleep, intermittent wakefulness and early-morning awakening. Episodes may come and go (be transient), last as long as 2 to 3 weeks (be short-term), or be long-lasting (chronic).

Common factors associated with insomnia include:

  • Physical illness
  • Depression
  • Anxiety or stress
  • Poor sleeping environment such as excessive noise or light
  • Caffeine
  • Alcohol or other drugs
  • Use of certain medications
  • Heavy smoking
  • Physical discomfort
  • Daytime napping
  • Counterproductive sleep habits:
    • Early bedtimes
    • Excessive time spent awake in bed

Disorders include:

  • Psychophysiological insomnia (learned insomnia)
  • Delayed sleep phase syndrome -- where a patient's internal clock is constantly out of synch with the "accepted" day / night phases; for example, patients feel best if they can sleep from 4AM to noon
  • Hypnotic-dependent sleep disorder -- insomnia that occurs when you stop or become tolerant to certain types of sleep medications
  • Stimulant-dependent sleep disorder -- insomnia that occurs when you stop or become dependent on certain types of stimulants

PROBLEMS WITH STAYING AWAKE

Disorders of excessive sleepiness are called hypersomnias. These include:

PROBLEMS STICKING TO A REGULAR SLEEP SCHEDULE

Problems may also occur when you do not maintain a consistent sleep and wake schedule. This occurs when traveling between times zones and with shift workers on rotating schedules, particularly nighttime workers.

Sleep disruption disorders include:

  • Irregular sleep-wake syndrome
  • Jet lag syndrome
  • Natural short sleeper (the person sleeps less hours than normal but has no ill effects)
  • Paradoxical insomnia (the person actually sleeps a different amount than they think they do)
  • Shift work sleep disorder

SLEEP-DISRUPTIVE BEHAVIORS

Abnormal behaviors during sleep are called parasomnias and are fairly common in children. They include:

When to contact a medical professional

Call for an appointment with your health care provider if lack of sleep or too much sleep is interfering with daily living.

Also call if non-breathing spells are observed during sleep.

Prevention

Maintaining regular sleep habits and a quiet sleep environment may prevent some sleep disorders.
