Getting enough sleep is vital for both physical and emotional well-being. Sleep deprivation can lead to many short- and long-term health effects. The Centers for Disease Control and Prevention CDC recommend that adults between the ages of 18 and 60 years get at least 7 hours of sleep a night.
However, approximately 35 percent of adults in the United States do not get enough sleep. People tend to experience the adverse effects of sleep deprivation within 24 hours. In this article, we explore how long a person can go without sleep and look at the effects of sleep deprivation over 72 hours. We also discuss the short- and long-term health effects of sleep deprivation, how much sleep a person needs, and how to improve sleep hygiene.
For example, infants require about twice as much sleep as adults. However, the amount of time that a person can survive without sleep remains unclear.
According to a review , the current world record for a person going without sleep is hours, which equates to just over 11 days. The most famous sleep deprivation experiment took place in when a Californian high school student named Randy Gardner managed to stay awake for hours. Toward the end of the 11 days, Gardner grew paranoid and even started hallucinating. However, he reportedly recovered without any long-term physical or psychological effects. Sleep deprivation occurs when a person gets less sleep than their body needs.
The effects of sleep deprivation can vary from person to person. Children and teenagers need more sleep than adults as their brains and bodies are still developing and growing. As such, the effects of sleep deprivation in children can sometimes be more severe or longer-lasting.
For example, sleep deprivation can increase the risk of dangerous accidents. An incredibly rare sleep disorder called fatal familial insomnia FFI can also result in death. The mutated gene produces misfolded prions that accumulate in the thalamus, which is the region of the brain that regulates sleep.
There is currently no cure for FFI, and death usually occurs within 12—18 months of a person first experiencing symptoms. Most people will begin to experience the effects of sleep deprivation after just 24 hours. In the U. People who have entered local sleep may appear fully awake, but their ability to perform complex tasks will significantly decline. The effects of sleep deprivation intensify the longer a person stays awake.
At this point, the brain will start entering brief periods of complete unconsciousness, also known as microsleep. Microsleep occurs involuntarily and can last for several seconds. After 72 hours without sleep, deprivation symptoms and fatigue will intensify even further. In a study , two astronauts experienced impaired cognitive functioning, increased heart rate, and a reduction in positive emotions after staying awake for 72 hours.
Sleep deprivation can have several adverse effects on health that will resolve once a person gets enough sleep. These can include an increased risk of:.
The CDC provide the following recommendations for how much sleep people need on average:. Quality matters as much as quantity when it comes to sleep. Practicing good sleep hygiene can promote higher quality sleep. People can improve their sleep hygiene by taking certain actions that can lead to improved sleep quality and daytime alertness.

Sleep hygiene tips include keeping to a consistent sleep schedule, winding down before bedtime, and avoiding caffeine in the evening. Caffeine stimulates the nervous system.

How to Calculate When You Should Go to Sleep
Sleep—and lots of it—is an essential part of childhood development. As babies turn into toddlers, and then school-age kids, and then teens, sleep patterns and sleep needs may shift. It's certainly not easy to keep tabs on how many hours your child gets, let alone whether that's enough.
The amount of sleep you need depends on various factors — especially your age. While sleep needs vary significantly among individuals, consider these general guidelines for different age groups:. Some people claim to feel rested on just a few hours of sleep a night, but their performance is likely affected. Research shows that people who sleep so little over many nights don't perform as well on complex mental tasks as do people who get closer to seven hours of sleep a night. Mayo Clinic does not endorse companies or products.

So if your son or daughter still naps, you'll need to take that into account when you add up his or her typical sleep hours. So, are you sending your child off to bed early enough? If those numbers are surprising to you, you're not alone. Working and single parents , especially, are often forced to get by on 5, 6, or even fewer hours of sleep each night. This is likely impacting your own social and mental functioning, as well as increasing your risk for other health problems. I t might be tempting to think that your children can also get by with less sleep than they need, or that they should be able to cope fairly well with a few skipped hours here and there.
Getting enough sleep is vital for both physical and emotional well-being. Sleep deprivation can lead to many short- and long-term health effects. The Centers for Disease Control and Prevention CDC recommend that adults between the ages of 18 and 60 years get at least 7 hours of sleep a night. However, approximately 35 percent of adults in the United States do not get enough sleep.
But how do you determine the number of hours of recommended sleep for you specifically? There are a few different strategies and some general guidelines for how much sleep is needed by age. Sleep calculators are free, widely available online , and can help you plan for your optimal bedtime.

How Much Sleep Do You Really Need Each Night?
There is some external commitment—caring for a child, getting ready for work or school, getting the dog outside—that dictates when we must wake and begin our day. Most of us do not have a wake time that is wholly within our control. Bedtime, on the other hand, offers us much more discretion and freedom. My two-part sleep calculator will help you do both. This simple sleep calculator uses information about your sleep cycle to get sufficient rest, maintain healthy circadian and sleep-wake rhythms, and wake naturally feeling refreshed and ready to begin your day. This formula tackles sleep quantity. The only information you need is your wake-up time. For example: You need to wake at 6 a.
Although the amount of sleep you get each day is important, other aspects of your sleep also contribute to your health and well-being. Good sleep quality is also essential. Signs of poor sleep quality include not feeling rested even after getting enough sleep, repeatedly waking up during the night, and experiencing symptoms of sleep disorders such as snoring or gasping for air. Improving sleep quality may be helped by better sleep habits or being diagnosed and treated for any sleep disorder you may have.

They're listed as ranges because gender has an influence, as well as lifestyle and health.
Michael Breus , sleep specialist and author of "The Power of When," says that the average person only needs 7. Everybody is different. Your sleep drive is a lot like your hunger drive. Just like your hunger drive makes you want to eat when you're feeling hungry, your sleep drive makes you want to sleep when you're feeling tired.

How much sleep did you get last night? What about the night before? Keeping track of your sleep schedule may not be a top priority, but getting enough sleep is critical to your health in many ways.
