excessive daytime sleepiness

Excessive sleepiness is the feeling of being especially tired or drowsy during the day. Unlike fatigue, which is more about low energy, excessive daytime sleepiness can make you feel so tired that it interferes with school, work, and possibly even your relationships and day-to-day functioning.

In a poll by the American Sleep Foundation, 18% of respondents reported experiencing excessive sleepiness. But the percentage may actually be much greater.

The key to overcoming excessive sleepiness is to determine its cause. There are several sleep-related problems that need to be evaluated before a diagnosis of IH can be given.

How to Know you Have Excessive Daytime Sleepiness?

Sleepiness is likely a problem for you if:

  • You have trouble waking in the morning.
  • You often feel sleepy during your waking hours.
  • Naps don’t take the edge off your sleepiness.

Along with having to drag yourself through the day, you may also have:

  • Loss of appetite
  • The trouble with thinking or memory
  • Feelings of irritability or anxiety

About 20% of adults have sleepiness severe enough to affect their regular activities.

What Causes Excessive Daytime Sleepiness?

There are many possible causes of excessive daytime sleepiness. One of the most common reasons is a chronic lack of sleep, whether due to long work hours, an irregular schedule, insomnia, or other reasons.

Excessive sleepiness can also be caused by getting fragmented or otherwise poor-quality sleep. Getting up multiple times a night to use the washroom, for example, disrupts the natural progression of the sleep stages and may reduce the proportion of restorative slow-wave sleep. Smoking, not exercising enough, and other lifestyle habits may also interfere with sleep quality and cause daytime sleepiness.

Many people who experience excessive daytime sleepiness don’t appear to have any problems sleeping enough. In these cases, sleepiness may be a sign of an underlying health condition or sleep disorder.

Sleep-Wake Disorders

Sleep disorders such as obstructive sleep apnea, restless legs syndrome, and periodic limb movement disorder are known for causing fragmented sleep. These conditions can cause micro-awakenings that disrupt the flow of sleep, though patients may not be aware they have these disorders until they visit a sleep doctor.

Other sleep-wake disorders act more directly on the neurological mechanisms that regulate the sleep cycle. Conditions such as narcolepsy and idiopathic hypersomnia are thought to influence the hormones responsible for promoting wakefulness, causing sleepiness during the day.

Similarly, people with circadian rhythm disorders experience a disconnect between their inner body clock and the times when they need to be awake. This disconnect can cause both insomnia while trying to sleep and also excessive sleepiness while awake.

Other Health Conditions

Chronic medical conditions and mental health disorders are often accompanied by daytime sleepiness. Common culprits include depression, anxiety, schizophrenia, lupus, Parkinson’s disease, multiple sclerosis, cancer, chronic pain, obesity, and hypothyroidism, among others.

Health conditions and sleep problems often have a bidirectional effect. A failure to sleep well can interfere with recovery, and may also predict diagnoses of health issues such as Parkinson’s disease further down the line. Emerging research suggests that the propensity for daytime sleepiness may even have a genetic component.

Medications used to treat health conditions may also cause daytime sleepiness as a side effect, as can substances such as alcohol or narcotics.


A noticeable change in your sleep schedule is one of the more common symptoms of depression. When you develop depression, you may sleep much more or much less than you used to.

If you aren’t sleeping well at night, you’re likely to experience excessive sleepiness during the day. Sometimes sleep changes are an early sign of depression. For other people, changes in sleeping habits occur after other signs appear.

Depression has many potential causes, including unusual levels of certain brain chemicals, issues with the regions of the brain that manage mood, and traumatic events.
