What is the longest a human can stay awake?
264 hours
The easy experimental answer to this question is 264 hours (about 11 days). In 1965, Randy Gardner, a 17-year-old high school student, set this apparent world-record for a science fair. Several other normal research subjects have remained awake for eight to 10 days in carefully monitored experiments.
Can you go 48 hours without sleep?
Missing sleep for 48 hours is known as extreme sleep deprivation. At this point, it’s even harder to stay awake. You’re more likely to have microsleeps. You might even begin to hallucinate.
How long can you stay awake before you hallucinate?
Although it’s unclear exactly how long humans can survive without sleep, it isn’t long before the effects of sleep deprivation start to show. After only three or four nights without sleep, you can start to hallucinate.
How can I survive a day without sleep?
These include:
- Drinking water. Dehydration will increase your fatigue, so it is important to drink lots of water.
- Soaking up the sun. After drinking a big glass of water, go outside and bask in the sunlight for 30 minutes.
- Napping. Find a time during the day to take a 10 to 45 minute nap.
- Drinking caffeine.
