Problem Sleepiness

What is problem sleepiness?

Everyone feels sleepy at times. However, when sleepiness interferes with daily routines and activities, or reduces the ability to function, it is called "problem sleepiness." A person can be sleepy without realizing it. For example, a person may not feel sleepy during activities such as talking and listening to music at a party, but the same person can fall asleep while driving home afterward.

What are the symptoms of problem sleepiness?

You may have problem sleepiness if you:

  • consistently do not get enough sleep, or get poor quality sleep;
  • fall asleep while driving;
  • struggle to stay awake when inactive, such as when watching television or reading;
  • have difficulty paying attention or concentrating at work, school, or home;
  • have performance problems at work or school;
  • are often told by others that you are sleepy;
  • have difficulty remembering;
  • have slowed responses;
  • have difficulty controlling your emotions; or
  • must take naps on most days.

What causes problem sleepiness?

Sleepiness can be due to the body's natural daily sleep-wake cycles, inadequate sleep, sleep disorders, or certain drugs.

Sleep-wake cycle

Each day there are two periods when the body experiences a natural tendency toward sleepiness; during the late night hours (generally between midnight and 7 a.m.) and again during the midafternoon (generally between 1 p.m. and 4 p.m.). If people are awake during these times, they have a higher risk of falling asleep unintentionally, especially if they haven't been getting enough sleep.

Problem Sleepiness

What is insomnia and what causes it?

Insomnia is difficulty in falling or staying asleep, the absence of restful sleep, or poor quality of sleep. Insomnia is a symptom and not a disease. The most common causes of insomnia are:

  • medications,
  • psychological conditions (for example, depression, anxiety),
  • environmental changes (for example, travel, jet lag, or altitude changes), and
  • stressful events.

Insomnia can also be caused by faulty sleeping habits such as excessive daytime naps or caffeine consumption.

Insomnia may be classified by how long the symptoms are present.

  • Transient insomnia usually is due to situational changes such as travel, extreme climate changes, and stressful events. It lasts for less than a week or until the stressful event is resolved.
  • Short-term insomnia usually is due to ongoing stressful events, med...
