What happens if you don’t get any sleep?
More precisely, what occurs to our brains and bodies if we decide not to sleep?
The study has shown that restricting our bodies’ required rest is far from beneficial.
We’ve created a sleep deprivation timeline based on scientific research and first-hand accounts of individuals who pushed the limits of sleeplessness.
Take a look at the infographic below to see what happens to one’s body after days, weeks, and even months without sleep. Keep scrolling to learn more about what happens if you don’t get enough shut-eye.
Is it possible to die from a lack of sleep?
Sleep deprivation can certainly kill you. That being said, you’re far more likely to die from a car accident, stroke, or heart attack before dying of sleep-related causes.
For example, individuals in China who spent days watching soccer have died as a result of difficulties caused by lack of sleep. Because of immune suppression, it’s also probable that you’ll catch a cold or other illness in addition to losing sleep.
Could one die as a result of sleep deprivation alone, in a completely controlled environment?
Despite attempts to place them into a coma or maintain them under controlled circumstances, those with the rare and deadly Fatal Familial Insomnia disease typically perish within months of its onset.
What Happens If You Don’t Get Enough Sleep?
Here’s a high-level overview of what happens when you don’t get enough sleep:
- You’re more likely to have a heart attack or stroke if you don’t get enough sleep. You’ve already substantially increased your risk of having either condition after missing even one hour’s sleep.
- As you progress from a few hours to almost a day without sleep, certain adverse effects begin to appear. Impaired judgment and memory will be the first symptoms.
- Sleep deprivation leads to a slew of physiological concerns, including hormone imbalances, immune system suppression, and elevated blood pressure.
If you’re thinking, “How many hours without sleep do I need to notice these changes?” it’s really hard to say.
However, for certain people, even a few lost hours might have significant effects on basic hormone functions, which can affect numerous organs.
What happens If You Stay Up For 24 Hours without sleep?
Is it harmful to stay awake for 24 hours?
Yes, unequivocally, a lack of sleep for 24 hours is very harmful, with mild symptoms to severe ones as a result.
Not sleeping for a whole day causes numerous issues, including the following:
- Overall cognitive impairment resembles someone with a BAC of 0.1%.
- Blood pressure increases
- Chronic excessive training reduces testosterone and increases cortisol (which has its own set of problems).
- Thyroid-stimulating hormone (TSH) levels go up.
- An increased number of cytokines (which cause inflammation) and a weakened immune system
- Overall lowering of all brain cell activity (similar to if all of your neurons had slowed down)
What Happens If You Don’t Get Sleep For Days?
If you miss several hours of sleep over the course of days, these are some of the consequences to your health:
- You’ll miss out on long-term memory development after 36 hours without sleep. Some individuals, such as soldiers, have had whole days vanish from their memories. You’ll also notice a greater incidence of stimuli triggering the flight-or-fight response.
- You’ll start to feel microsleeps (if you haven’t already) at 48 hours without sleep, or two days, as well as decreased insulin and a variety of taxis, including slurred speech.
- Researchers have noticed hallucinations, memory loss, light sensitivity, and an increase in prior symptoms such as emotional melancholy at 72 hours without sleep. After three days without sleep, most people’s desire to sleep will outweigh their appetite for food.
What Happens If You Don’t Sleep For A Week?
A healthy individual’s risk of death becomes 10 times higher, and they’ll lose their ability to recognize happiness or sadness in others.
People will also start to hear voices, though not necessarily understand them.
In the wake of missing out on the sleep needed for a week, people will also lose their grip on reality.
Could someone go without sleep for long periods of time, such as days or weeks?
What happens when you don’t get any sleep for a longer period than a few days, such as a week or more?
Is it dangerous to stay up nights and not sleep for an entire week?
Here’s a short list of what happens:
- Brain hemorrhage and seizures (when the brain is severely sleep deprived)
- Cardiac arrest (which can cause sudden death, particularly in those with other serious health issues such as heart disease)
- Death (at the end of a few weeks, if you haven’t already succumbed
Sleep deprivation has a number of negative effects on the brain.
Researchers who haven’t slept for more than a few hours have had very strange experiences on Day 4 and Day 5 of not sleeping.
Hallucinations, paranoia, and even doubts about one’s own reality are among them.
Peter Tripp conducted a “sleep deprivation public relations stunt” on the air.
Tripp attempted to keep awake for 200 hours, broadcasting his program at that time.
Around 120 hours in, it was mentioned that he was hallucinating. He thought a scientist was an undertaker and fled from him once before.
How Long Can You Go Without Sleep?
Several people have tried to outlast their sleep deprivation in previous years.
Randy Gardner, for example, who endured 264 hours without sleeping or 11 days.
Toimi Soini set the Guinness world record for staying awake without sleep by staying awake for 276 hours and 15 minutes, according to the official case of Maureen Weston, who went without sleep for 499 hours, or more than 9 days.
Other people have been documented staying awake for over a week without sleeping.
However, these cases were often aided by powerful stimulants and other medication to keep them awake and going.
The human body was not designed to go without sleep for this long, especially when it is active, which further exacerbates the brain’s need for sleep.
Even if you aren’t using stimulant drugs, the brain craves sleep after a few days of not sleeping.
There is no definitive answer on how long someone can go without sleep.
People will naturally start to feel tired around day three or four when they haven’t slept in some time. Going past that point carries significant risks.
How Long Can You Go Without Sleep Before You Die?
The University of Chicago’s Allan Rechtschaffen attempted to figure out how long you can survive without sleep.
He performed tests on rats, but after 32 days, all of his rats died. Based on a limited study, it appears that willpower to go without sleep fades after about 11 days.
People compelled to live without sleep may survive anywhere from a couple of days to a week.
Has anyone died because of sleep deprivation?
Yes. Fatal Familial Insomnia is a genetic condition that prevents sufferers from sleeping soundly, and it’s caused by an uncommon mutation in the brain.
Even though doctors attempted to put him into a coma, Corke’s mind could not be shut down.
He died in 1993 after going without sleep for six months.

Sleep Deprivation After an Accident
However, if your body is experiencing sleep deprivation after a car accident or other traumatic incident, this is hardly the time to try and last longer.
Medical professionals advise that you get proper rest when recovering from the remnants of a serious trauma whether it’s one that was caused by an accident or not.
Sleep deprivation is dangerous and can lead to other complications that could put your life at risk.
Do You Really Need 8 Hours Of Sleep Every Night?
A lack of sleep can cause significant bodily damage, from microsleeps to hallucinations to increased risks of serious problems such as heart attacks and strokes.
A few hours of sleep deprivation can have a variety of consequences for some individuals, including an increased risk of diabetes and obesity, as well as sadness and drowsy driving.
According to the CDC, adults require at least seven to eight hours of sleep daily, children between eight and ten hours, and seniors aged 70 or older need at least seven hours of sleep every night.
It’s critical for your general health to get adequate and constant rest, not just because of the risk factors but also because people who get more sleep tend to be more productive.
If you’re having difficulty obtaining a better night’s sleep, consider investing in a new mattress.
We’ll not only evaluate mattresses for you, but we’ll also help you choose the best pillow and comforter and mattress topper to complement it.
This can assist you in making a purchase that will provide greater shuteye. One last thing, if you want to know how long can people stay awake without sleeping, well, no one really knows.
But if it comes down to it, you might not feel so hot after a few days of sleep deprivation…
