When you go without sleep for 48 hours, you enter the third stage of sleep deprivation.
The most common effects during this time frame include:
- heightened stress levels
- intense urge to sleep
- extreme fatigue
In this article, we dive into the stages, symptoms, and effects of sleep deprivation. We also provide recovery strategies and prevention tips so you know how to improve your ability to sleep at night.
Remember, prolonged sleep loss can have severe consequences. So, it’s best to act as soon as you identify the first sleep deprivation symptoms.
Without further ado, here’s what you need to know to never miss a night of sleep again.
- After going 48 hours with no sleep, you may experience extreme sleep deprivation, making it harder to stay awake and leading to more frequent microsleeps.
- Symptoms of sleep deprivation can worsen at this stage, including the possibility of hallucinations, depersonalization, anxiety, heightened stress levels, and increased irritability.
- Impaired perception, complex hallucinations, illusions, delusions, and disordered thinking can occur after being awake for 72 hours.
- When awake for 96 hours or more, the perception of reality can become severely distorted, accompanied by an unbearable urge for sleep.
- If unable to interpret reality, sleep deprivation psychosis may occur, which typically goes away with sufficient sleep.
The Effects of 48 Hours Without Sleep
Going without sleep for extended periods can harm your body and mind. This condition is called sleep deprivation. It has different stages, which are based on how many hours of sleep you miss.
The longer you go without sleep, the worse the effects will be.
The initial 24 hours can be tough. You might notice slower reaction times, slurred speech, and a lapse in judgment and memory.
You could compare these effects to having a blood alcohol concentration of 0.1%.
Your senses, like vision and hearing, as well as your hand-eye coordination, might also take a hit.
By the time you’ve gone 48 hours without sleep, you’re deep into stage three. You’re now dealing with severe sleep deprivation.
Staying awake becomes a struggle. You might experience something called microsleeps, which are brief, unintended episodes of loss of attention.
Overwhelming fatigue sets in. You might also feel more irritable, anxious, and stressed.
Finally, you may start seeing things that aren’t there, feeling detached from yourself. Fatigue is your constant companion at this point.
It’s worth noting that regularly not getting enough sleep, known as chronic sleep deprivation, can lead to long-term health problems. These can range from cognitive issues to an increased risk of conditions like obesity and diabetes.
It can also weaken your immune system and cause heart problems.
The best way to recover from sleep deprivation is to make sleep a priority. Here are five things you can do to pay down your sleep debt:
- Practice good sleep hygiene.
- Aim for 7 to 9 hours of sleep every night.
- Develop a relaxing bedtime routine.
- Stay away from caffeine and electronic devices before bed.
- Make your sleeping space as comfortable as possible.
24 Hours Without Sleep
The first stage of sleep deprivation kicks in after 24 hours of no sleep. You’ll start to feel tired or drained.
On top of that, you might feel an intense need to sleep and could experience brief, involuntary periods of shut-eye, known as microsleeps.
This stage of sleep deprivation causes the least amount of damage out of all. Still, it shouldn’t be underestimated.
Pulling an all-nighter is playing with fire, as it opens the door to a range of sleep disorders, such as sleep apnea and parasomnia.
36 Hours Without Sleep
The effects of sleep deprivation will become more severe the longer you stay awake.
The body starts to protest after just one night of missed sleep. Yet, as the sleepless hours pile up, the situation will only become more problematic.
Staying awake for 36 hours is when the lack of sleep really catches up with you. These extended hours without sleep come with alarming effects on both physical and mental health.
Initial symptoms include:
- lack of concentration
- decreased ability to think quickly
72 Hours Without Sleep
Survive three days without sleep, and the situation gets even worse.
After reaching the 72-hour mark, the desire to sleep is almost unbearable. Microsleeps are longer and more frequent. Your perception of the world around you starts to warp.
Your emotions might be all over the place. You could feel irritable, anxious, even depressed.
Worst of all, you may see complex hallucinations, have delusions, or experience disordered thinking.
At this point, recovering from sleep deprivation will be a long process. Even if you prioritize sleeping about 7 to 8 hours per night, you may wake up groggy the next day. It might take weeks for your body to recover.
96 Hours Without Sleep
If you push through to 96 hours or more without sleep, you’ve hit stage five. It is a truly dangerous territory. Your perception of reality can become severely warped, and the need for sleep will become nearly overpowering.
In some cases, you might even experience sleep deprivation psychosis, making it hard to tell what’s real.
Ultimately, sleep deprivation can lead to serious health issues like hypertension, heart attack, stroke, or diabetes. It weakens the immune system, making the body more susceptible to diseases.
The good news? These effects usually disappear once you get enough sleep.
You can recover from sleep deprivation by sticking to good sleep habits and making sure you get 7 to 8 hours of sleep each night.
But remember, the longer you go without sleep, the longer it may take to fully recover.
Despite the urgency of that looming deadline or pending exam, getting enough sleep is necessary for good health. Before you decide to sacrifice sleep in favor of work, think twice about the potential consequences.
Recovery Strategies for Sleep Deprivation
Sleep deprivation impairs the accurate recognition of human emotions and leads to numerous other issues that can lower your quality of life. A simple yet effective way to recover is to ensure you get enough quality sleep.
Here are some strategies that can help you bounce back, fall asleep faster, and improve sleep quality:
- Maintaining a consistent sleep schedule is crucial. Try to hit the sack and wake up at the same time daily. Yes, even on weekends! Doing this will help regulate your internal clock, enhancing the quality of your sleep. Experts suggest sleeping for 7-9 hours each night.
- Creating a sleep-friendly environment does wonders. Your bedroom should be cool, dark, and quiet. If outside noises are a distraction, use earplugs or a white noise machine.
- Make your bed as comfortable as possible. Adjust your pillows and blankets to meet your comfort needs. This relaxation act can make you drift off to sleep faster.
- Follow a relaxing bedtime routine. Why not take a warm bath, stretch out those tired muscles, or meditate? You can even lose yourself in a good book. These calming activities are your body’s cue to wind down and get ready for sleep. A routine like this can also help set your internal clock right, making falling asleep easier.
Try these tips and see which ones work for you. After all, we’re all different. What works for one might not work for another.
