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.
