However, there are some problems with using Gardner as a benchmark. Randy Gardner currently holds the world record for losing sleep, with a total time spent awake of 11 days and 25 minutes. One study into sleep deprivation does give us a slight insight into how long a human being might be able to survive without sleep. The truth is that every hour you go without sleep has an impact on your health and overall wellness.Īdditionally, because all of us have different needs when it comes to snoozing, it’s hard to know what your limit is when it comes to answering “how long can you stay awake”.

It turns out that the human body doesn’t actually work like that. Sure, you’re going to feel a little groggy the next day, but you’ll catch up on sleep later right? Maybe you’ve got a day off from work, or you’re relaxing on the weekend. How often have you tried to convince yourself that one all-nighter isn’t going to affect your health?

Perhaps you’ve even asked, “How long can you go without sleep without facing serious consequences?” If you’ve ever spent a night staring at the ceiling or trudged through a morning at work after only a couple of hours of shut-eye, you might have found yourself asking, “How long can you stay awake?” Maybe we need more time to work on something important, like a project for school.

However, getting that regular dose of slumber every night is easier said than done. You may have heard that the CDC (Centre for Disease Control and Prevention) recommends that all adults over the age of 18 should try to get at least 7 hours of sleep each night. “You're more emotional, attention is decreased, hearing is impaired, and there is an increase in your risk of death from a fatal accident.You already know that sleep is important. The consequences of sleep deprivation at 24 hours is comparable to the cognitive impairment of someone with a blood alcohol content of 0.10 percent, according to a study published in the International Journal of Occupational Medicine and Environmental Health. ( 2) “Judgment is affected, memory is impaired, there is deterioration in decision-making, and a decline in eye-hand coordination,” Cralle says. But what happens in more normal circumstances is surprising. Kelley's military training and adrenaline-filled environment seemed enough to keep him focused and alert at this early stage of sleep deprivation. “There were several occasions in Afghanistan and Iraq where I had just finished up 15 to 20 hours of working, got back to my hooch, and then either a rocket attack would come in or a critical mission would be called,” he says. With multiple deployments under his belt, Kelley has had many instances of being awake longer than 24 hours in the field. Scott Kelley, a 10-year Army veteran, knows about sleep deprivation. Less insulin is released after you eat, and this along with the increased cortisol may lead to too much glucose in the bloodstream and thus an increased risk for type 2 diabetes. In addition, skimping on sleep seems to throw other body hormones out of whack. Poor sleep can lead to an increase in the body's production of cortisol, also known as the stress hormone. During sleep, our bodies secrete hormones that help control appetite, metabolism, and glucose processing. “Sleep, along with diet and exercise, constitutes the very foundation of good health." In fact, she says, the three are so interconnected that each needs to be a priority.Ĭhronic poor sleep puts us at increased risk for serious medical conditions, such as obesity, heart disease, and diabetes. “As a society, as families and individuals, we have not yet fully appreciated the importance of sleep,” says Terry Cralle, RN, a certified clinical sleep educator in Fairfax, Virginia. In extreme circumstances, sleep deprivation can ultimately lead to death. While the occasional lack of sleep may not seem like a big deal, the impact of sleep deprivation can be intense and its effects can linger. All-night study sessions, important business deals, new babies - most people will experience a taste of sleep deprivation at some point in life.
