Guide to Sleep Disorders

Published March 9, 2013 by teacher dahl


What Are Sleep Disorders?

Sleep disorders are conditions that affect how much and how well you sleep. The causes range from poor habits that keep you awake to medical problems that disrupt your sleep cycle. If you don’t feel rested in the mornings, see your doctor. Insufficient sleep is a serious problem that poses a threat to your health and safety.

Symptoms of Sleep Disorders

Symptoms vary depending on the type of sleep disorder but may include:

  • Excessive sleepiness during the day
  • Trouble falling asleep or staying asleep
  • Snoring or brief pauses in breathing during sleep
  • Urge to move your legs at rest or an uncomfortable feeling in the legs at night

The Sleep Cycle

There are two forms of sleep: REM sleep and non-REM sleep. REM stands for rapid eye movement and is associated with dreaming. It accounts for 25% of normal sleep, coming in longer periods toward morning. The rest of our sleep time is spent in NREM, which consists of four stages from light sleep (stage 1) to deep sleep (stage 4). Sleep disorders interfere with normal sleep cycles, preventing a good night’s rest.

How Much Sleep Is Enough?

Sleep needs vary widely from person to person, but general guidelines are:

  • 16 hours for infants
  • 9 hours for teenagers
  • 7-8 hours for adults

Keep in mind that some adults do fine with 5 hours of sleep and others need as many as 10 hours per night.


Most people have trouble sleeping once in awhile, but when the problem lingers night after night you may have insomnia. People with insomnia may lie awake for hours before falling asleep. They may wake up too early and be unable to drift off again. Or they may wake up repeatedly throughout the night.
