Sufficient, healthy sleep duration is a vital part of our physical and mental well-being. It’s a biological necessity that also reduces injury and accident risks [30]. However, not all of us enjoy sufficient sleep.

As we read through several studies, we found many interesting facts and stats about sleep and sleep disorders.

What Percentage of the Population Has Insomnia?

30% to 40% of American adults complain of insomnia symptoms [12]. Insomnia is the most common type of sleep disorder.

The worldwide prevalence of insomnia varies. Some studies say it affects 10% to 30% of the worldwide population [6]. Others say the prevalence rate of insomnia can go as high as 50% to 60% of the global population [6].

What is the Average Amount of Sleep a Person Gets?

Americans usually have around an average of 6.8 hours of sleep each night, says a 2013 Gallup report. This is more than an hour less than the average sleep we got in 1942 of 7.9 hours [19].

29% of people get at least 8 hours of sleep, while 14% only get 5 hours of sleep [19].

Adults need anywhere between 7 and 9 hours of sleep, says the Centers for Disease Control and Prevention (CDC) [26].

The younger the adult, the more they need longer sleep. However, it’s interesting to note that Gallup’s report shows the opposite patterns.

Of all age groups, it’s the young adults (18 to 29) who get the least amount of sleep. 46% or almost half of their population only get six hours or less of sleep [19].

The age group that enjoys the most sleep is the older adults (65+). 67% of them get seven hours or more of sleep each night [19].

How Much Sleep Should We Get?

Adults (18 to 65+ years) need at least 7 to 9 hours of sleep. Teens (13 to 18 years) need 8 to 10 hours of sleep [26].

Children between 6 and 12 years old need at least 9 to 12 hours of sleep, while those between 3 and 5 years old need 10 to 13 hours of sleep with naps [26].

Toddlers (1 to 2 years) need 11 to 14 hours of sleep with naps, while newborns and infants need anywhere from 12 to 17 hours of sleep with naps [26].

37.5% say they’re awakened too early.
14.3% report excessive sleepiness during the day.
6.1% say nightmares keep them up at night.

32.1% or almost one-third of them say this happens each night [1].

Sleep onset latency, or the time it takes a person to fall asleep, is usually 15 to 20 minutes [20]. However, it takes Americans an average of about 27 minutes to fall asleep [24].

Only 37% of the people surveyed fall asleep in under 15 minutes. 11% of them say it takes them more than an hour to fall asleep [24].

Worldwide, 51% of the respondents in a global survey say that they’re dissatisfied with the quality of their sleep. 49% say they’re satisfied [2].

Sleep research shows insufficient sleep can contribute to the development of chronic mental and physical health problems including [18]:

Heart diseases, including hypertension
Obesity
Metabolic problems like diabetes
Stroke
Heart attack
Mental health problems like depression, anxiety, and increased suicide risk [22]

Insufficient sleep affects men slightly more than women — 33.3% of men and 32.1% of women [5].

Insufficient sleep is more common among Hawaiian/Pacific Islanders at 46.2% than Asians at 30.5% [5].

In just 10 years, the insomnia prevalence rate increased by 8% [12].

10% to 30% of American adults have insomnia, says the American Sleep Association (ASA) [37].

30% of them deal with short-term insomnia.

The CDC defines insomnia as the difficulty to initiate as well as maintain sleep. It may also be characterized by waking up several hours before daytime and the inability to go back to sleep [25].

Who Does Insomnia Affect the Most?

Insomnia affects women the most, with more than 1 in 4 women in the US reporting insomnia. Among the male population, insomnia affects less than 1 in 5 men [16].

Genes also play a role. 34.9% of people with insomnia have a first-degree relative who also has past or current insomnia problems. 19.7% of them say that the first-degree relative is their mother [4].

According to the University of Michigan (Michigan Medicine), there are three possible reasons why women are more prone to insomnia than men [10]:

Women go through many hormonal milestones in life. These include monthly periods, pregnancy, post-pregnancy, and menopause — all of which can affect sleep schedule.
Anxiety and mood problems affect women more than men. These two conditions then affect their sleep.
Women also have to balance work and caregiving duties more than men. Women have always been the caregiver within the family. These are responsibilities that can affect their sleep time.

Insomnia affects people with some college education the most at 26.4%. It affects those with less than a high school education the least at 19.9% [17].

Long sleeping or hypersomnia affects 4% to 6% of the population [11]. People with this rare type of sleep disorder often sleep nine hours or more each night.

Hypersomnia differs from regular oversleeping. If you’re experiencing these hypersomnia symptoms, be sure to seek professional help:

Excessive daytime sleepiness despite getting enough sleep
Difficulty waking up
Doesn’t fully feel awake after being awakened abruptly
Taking naps several times a day
Not feeling refreshed and always feeling tired
Symptoms occur at least thrice a week for over three months
