Drowsiness

Alternate Names : Sleepiness - during the day, Hypersomnia, Somnolence

Definition

Drowsiness refers to feeling abnormally sleepy during the day. People who are drowsy may fall asleep in inappropriate situations or at inappropriate times.

Overview & Considerations

Excessive daytime sleepiness (without a known cause) suggests that you have a significant sleep disorder. It is different from fatigue.

Depression, anxiety, stress, and boredom can all contribute to excessive sleepiness, but these conditions more typically cause fatigue and apathy.

Common Causes

Having to work long hours or different shifts (nights, weekends)
Medications (tranquilizers, sleeping pills, antihistamines)
Medical conditions (such as hypothyroidism, hypercalcemia, and hyponatremia /hypernatremia)
Not sleeping for long enough
Sleep disorders (such as sleep apnea syndrome and narcolepsy)
