Ahhh… sleep! It feels like you can never get enough of it. Sometimes, it seems like you’re not getting enough rest, but have you ever wondered what would happen if you stopped sleeping altogether? Surprisingly, scientists still don’t fully understand why we sleep or how it evolved. After all, being unconscious for hours while predators are around doesn’t seem very safe. However, some interesting connections have been found. For example, adults who sleep between 6 to 8 hours a night tend to live longer. On the flip side, too much sleep can lead to health problems like heart disease and diabetes. Not getting enough sleep over time has also been linked to heart issues, obesity, depression, and even brain damage.
So, what happens if you stop sleeping right now? After your first night without sleep, your brain’s reward system gets a boost, making you feel more energetic, motivated, and positive. You might even notice an increase in your sex drive. While this might sound great, it can also lead to impulsive behavior because your brain starts to shut down areas responsible for planning and decision-making. Once you start feeling really tired, your reaction times slow down, and your ability to think clearly decreases. After a day or two without sleep, your body has trouble processing glucose, and your immune system becomes weaker. In some cases, going three days without sleep can cause hallucinations.
Worried about how you look? Studies show that not getting enough sleep can make you appear less healthy and less attractive compared to those who are well-rested. The longest scientifically recorded time someone stayed awake was 264 hours, or 11 days. While these people had trouble concentrating and perceiving things, they didn’t suffer any serious long-term health effects. However, this doesn’t mean that staying awake for too long won’t cause permanent damage.
Experiments on rats have shown that sleep deprivation generally leads to death after about two weeks, although it’s unclear if this is due to lack of sleep or the stress of being constantly disturbed. There’s also a rare genetic disease called fatal familial insomnia, which causes people to gradually lose the ability to sleep. This leads to hallucinations, dementia, and eventually death. This disease has affected around 100 people worldwide, with an average survival span of about 18 months. Over time, the lack of sleep worsens, and the body’s organs begin to shut down.
So, while not sleeping won’t necessarily lead to immediate death, ongoing sleep deprivation can have negative effects on your health. Sleep well!… but not too much!

Keep a sleep diary for one week. Record the hours you sleep each night and note how you feel each day. At the end of the week, analyze your data to see if there’s a pattern between your sleep duration and your mood or energy levels. Discuss your findings with the class.
Participate in a debate about the importance of sleep. Split into two groups: one advocating for the benefits of sleep and the other highlighting the potential advantages of staying awake longer. Use evidence from the article to support your arguments.
Conduct a simple experiment to test reaction times after different amounts of sleep. Use a ruler drop test to measure how quickly you can catch a falling ruler. Compare your results after a full night’s sleep and after a shorter sleep period. Share your results with the class.
Write a short story imagining a world where people no longer need to sleep. Consider how this change would affect daily life, health, and society. Share your story with classmates and discuss the potential pros and cons of such a world.
Research a sleep disorder such as insomnia, sleep apnea, or narcolepsy. Create a presentation explaining the disorder, its symptoms, and possible treatments. Present your findings to the class and discuss how these disorders impact people’s lives.
Sure! Here’s a sanitized version of the YouTube transcript:

Ahhh… sleep! It seems like you can never have enough of it. Sometimes, it feels like you’re not getting enough, but what if you stopped sleeping altogether? Interestingly, science understands relatively little about why we sleep or how it evolved. After all, being unconscious for hours while predators are around doesn’t seem advantageous. However, some correlations have been discovered. For instance, adults who sleep between 6 to 8 hours a night tend to live longer. On the other hand, excessive sleep can lead to health issues, including cardiovascular disease and diabetes. Chronic sleep deprivation has also been linked to cardiovascular problems, obesity, depression, and even brain damage.
So, what happens if you stop sleeping right now? After your first sleepless night, your brain’s reward system becomes stimulated, leading to increased energy, motivation, positivity, and even sex drive. While this may sound appealing, it can lead to impulsive behavior as your brain starts to shut down areas responsible for planning and decision-making. Once exhaustion sets in, you’ll experience slower reaction times and reduced cognitive functions. After a day or two without sleep, your body struggles to metabolize glucose properly, and your immune system becomes less effective. In some cases, three days without sleep can lead to hallucinations.
Concerned about your appearance? Studies show a direct correlation between sleep deprivation and perceived beauty; sleep-deprived individuals often appear less healthy and attractive than those who are well-rested. The longest scientifically documented period of wakefulness was 264 hours, or 11 days. While those individuals experienced concentration and perception issues, they did not suffer serious long-term health effects. However, this doesn’t mean that prolonged sleep deprivation won’t cause permanent damage.
Experiments on rats have shown that sleep deprivation generally leads to death after about two weeks, although it’s unclear if this is due to lack of sleep or the stress of being constantly disturbed. A rare genetic disease called fatal familial insomnia causes progressively worsening sleeplessness, leading to hallucinations, dementia, and ultimately, death. This disease has affected around 100 people worldwide, with an average survival span of about 18 months. Over time, the lack of sleep worsens, and the body’s organs begin to shut down.
So, while a lack of sleep won’t necessarily lead to immediate death, ongoing sleep deprivation can have negative effects on your health. Sleep well!… but not too much!
