Sleep disorders and lack of sleep have a dynamic impact on health. In the short term, a person can suffer a lack of alertness, impaired memory and relationship stress. If you’re a long time sufferer, there can be weight gain and obesity, diabetes, depression, immune system deficiency and hypertension.

SleepApneaZone strives to keep people informed about the importance of getting their rest. In that regard, we’ve compiled a list of sleep statistics about sleep and sleep disorders.

Sleep Disorders

Signs of sleep disorders include irregular breathing, excessive day sleepiness and restlessness. Other symptoms are irregular wake cycles, and difficulty falling and staying asleep.

There are two major types of sleep disorders. There’s sleep apnea and sleep deprivation. We group them according to behaviors, sleep cycle patterns and breathing issues. This helps us understand specific characteristics and explain how they affect you.

Sleep Apnea

Sleep apnea entails unnatural patterns in breathing while you sleep. Sleep apnea itself comes in several types.

Obstructive Sleep Apnea

Obstructive sleep apnea affects 2% of women and 4% of men, though it’s believed most sufferers are never diagnosed. This is the result of a blockage of airways while you sleep. The throat closes up and you wake to breathe. Mild sufferers experience anywhere between five and 14 episodes in a single hour. Moderates have 15–30 every hour. Severe sufferers will go through 30 or more interruptions an hour. This disorder is attributed to snoring and morning headaches.

Central Sleep Apnea

During sleep, the brain temporarily stops signaling muscles that control breathing. This is central sleep apnea. It is estimated 20% of apnea cases are central sleep. Individuals with medical conditions that affect the brainstem are more likely to suffer this affliction.

Mixed Sleep Apnea

Patients with obstructive sleep apnea using CPAP machines have developed symptoms of central sleep apnea after PAP therapy. In 2006, a study found, of 223 patients, 15% of the participants who suffered from obstructive sleep apnea also showed symptoms of central sleep apnea.

Sleep Disorder Statistics

  • Adults with a sleep disorder: 50-70 million
  • Snorers: 48.0% reported
  • Fell asleep at least once during the day in preceding month: 37.9%
  • Nodded off / fell asleep while driving at least once in the previous month: 4.7%
  • Adults suffering obstructive sleep apnea: 25 million total (women, 9–21%; men, 24–31%)
  • Proportion of obese adults suffering short sleep: 3–5%
  • CPAP users adherent to therapy: 66%
  • Percentage of adults using melatonin: 1.3%

  • Percentage of reported improved snoring in bed where partner used an advancing mandibular snoring device: 70%

Other Stats

Annually, drowsy driving is responsible for 40,000 nonfatal injuries and 1,550 fatalities.

The most common specific sleep disorder is insomnia. Short term insomnia happens to about 30% of adults with chronic insomnia at 10%.

Sleep Deprivation

Sleep deprivation is when you aren’t getting enough sleep on a regular basis. Unlike sleep apnea or insomnia, sleep deprivation isn’t always a condition. While there are situations where a medical condition can prevent sleep many are not getting sleep for reasons that have nothing to do with their health.


Even if unintentional, there are people who restrict their sleep. This is called behaviorally induced insufficient sleep syndrome, and is a form of hypersomnia. Any of the following categories of sleep deprivation play a part in voluntary deprivation.

Personal Obligation

Sufferers in this group restrict sleep time because of personal matters. Time where they could sleep is spent dealing with these matters.


Not getting enough sleep for professional reasons is quite common.


Like sleep apnea, a medical condition could prevent sleep.

Sleep Deprivation Statistics

  • Reported short sleep duration (20-39 year-olds): 37%
  • Reported short sleep duration (40-59 year-olds): 40%
  • Less than seven hours of sleep: 35.3%
  • Of the average 100,000 deaths every year in US hospitals, sleep deprivation is reported to be a significant contribution.
