Sleep Statistics: What You Should Know Right Now

We’re all looking forward to a restful night’s sleep. Isn’t it possible that not all sleep is equal? Sleep is crucial to good health. There’s no better way to recharge and get ready for the day than getting some shut-eye.

Due to some sleep issues, a large percentage of the population is deprived of sufficient sleep.

Sleep disorders, medical conditions, and mental health issues all may play a role in the lack of or poor quality of sleep. People of all ages struggle with sleep problems, which can have far-reaching consequences.

One-third of our lives are spent sleeping, believe it or not. Even though it seems like a lot of time in bed, sleep deprivation is a major problem in the United States.

Every week, as many as 164 million Americans find it difficult to get a good night’s sleep and it has been labeled as a “public health problem” by the Centers for Disease Control and Prevention (CDC).

As difficult as it may seem at first, reviewing some basic facts and figures about sleep can give you a better idea of how sleep works, why it’s so important, and the extent to which Americans are suffering from sleep deprivation.

Sleep Statistics

Everyone knows that getting enough sleep is important for both our physical and mental health, but few people know how important it is to get enough. The truth is that we don’t think about how important sleep is.

You should all take your sleep more seriously. If you or someone else knew all this, they might live. Below are the must-read sleep statistics giving you better insight that sleep disorders and sleep deprivation are not a joke.

General Sleep Data and Statistics

A lack of sleep can have negative effects on your physical and mental well-being, as well as a host of unpleasant symptoms.

When you don’t get enough sleep, it can lead to a variety of symptoms, including fatigue, mood swings, forgetfulness, irritability, daytime sleepiness, and other negative emotions.

A person’s specific needs for sleep will vary according to their age, but children generally require more sleep than adults to maintain healthy development. Below are the required sleep according to age:

  • Adult: 7 – 9 hours
  • Teenager: 8 – 10 hours
  • 6 – 12 years: 9- 12 hours
  • 3 – 5 years:  10 – 13 hours (including naps)

  • Dreaming occurs four to six times a night, but most of us forget 95 to 99 percent of our dreams the next day. We dream for an average of two hours each night.
  • Only 20% of our total sleep time is spent in REM sleep (Rapid Eye Movement: is the lightest stage of sleep, during which a person may wake easily) while the rest is spent in non-REM sleep stages. The amount of REM sleep in healthy adults ranges from 20% to 25% of total sleep. NREM (Non-REM) sleep reduces metabolism by about 15%.

Sleep Disorders Statistics

Sleep Disorders Statistics

You may have a sleep disorder if you don’t get enough sleep regularly. Chronic sleep deprivation harms a person’s quality of life, and this is the hallmark of a sleep disorder.

There are several conditions characterized by an inability to sleep well, either in terms of quality or quantity.

In some cases, this can include a lack of quality sleep that interferes with daytime productivity.

A sleep disorder can be diagnosed by a medical professional if a patient exhibits certain symptoms, such as sleepiness during the day and difficulty sleeping at night.

In most cases, the diagnosis can be made after a thorough clinical evaluation by your physician, which typically includes a detailed history of the presenting complaints, sleep logs, and possibly sleep studies.

The following are the seven types of sleep disorders:

  • Chronic insomnia is the most common cause of insomnia.
  • Obstructive sleep apnea and snoring are two common sleep breathing disorders.
  • Narcolepsy and idiopathic hypersomnia are examples of central hypersomnolence disorders.
  • Jet lag and delayed sleep-wake phase disorder are examples of circadian rhythm sleep-wake disorders.
  • Sleepwalking, rapid eye movement (REM) behavior disorder, and sleep paralysis are all examples of parasomnia.
  • Repetitive movement disorders, such as restless leg syndrome, affect sleep.

How common is a sleeping disorder?

Make an appointment with your healthcare provider if you’re having trouble sleeping and don’t know what to do about it.

They will be able to determine whether or not you have a sleep disorder and devise a treatment plan that works with your schedule and your needs.
