Sleep is a necessity for humans, but what if we didn't need it? While it may seem appealing to have more time in the day, the reality of a sleep-free life is more complex. Researchers are exploring methods to eliminate the need for sleep, such as a nasal spray containing the hormone orexin-A, which has shown promising results in reversing sleep deprivation in trial monkeys. However, experts caution that forgoing sleep may have unintended health consequences, such as obesity and heart disease, due to increased opportunities for eating and a tendency to prioritise pleasure over health. Additionally, without sleep, people might burn out more quickly and would lose the ability to dream.

What You'll Learn
Humans would have inexhaustible energy and strength
If humans did not need to sleep, they would have inexhaustible energy and strength. They would have eight more hours in the day to do things, and would likely be more productive. However, experts say that most people would not make the best use of this extra time. Without the need to sleep, people would not require beds or permanent residences, and would be more nomadic. They would also have more opportunities to eat, which could lead to increases in obesity.
Humans would also have more time to exercise, but they tend to gravitate towards things that bring pleasure, so they may not make healthy choices. Not requiring sleep, humans would also have more time and energy for sex, and orgies would be more common.
Without sleep, people would not dream, and they would likely develop night vision. They would also be at risk of burning out quickly. While there are researchers working on methods to prevent sleep, such as a nasal spray with the hormone orexin-A, there is currently no cure for sleep.

Work hours would increase
If humans did not need to sleep, work hours would increase. People would have eight more hours in the day, which would likely be spent working. This would mean that work hours would be around 20 hours a day.
However, experts say that most people would not make the best use of this extra time. While it is tempting to think that people would become more productive and get more done, this may not be the case. People might instead spend the extra time procrastinating or doing things that bring pleasure, such as eating, which could lead to an increase in obesity.
Without the need to sleep, people would not require beds or permanent residences and would be more nomadic. They would also have inexhaustible energy and strength. This could lead to an increase in sexual activity, with more sex happening standing up and an increase in orgies.
While people would have more time to work, they might not be as productive as expected due to burnout. If there was no such thing as sleeping, people would burn out quickly. Therefore, while work hours would increase, the overall productivity of workers might not increase as much as expected.

People would be more nomadic
If humans did not need to sleep, they would be more nomadic. Without the need to sleep, people would not require beds or permanent residences. They would have inexhaustible energy and strength, and work hours would probably be 20 hours a day.
With the extra time, people may be more productive and society would solve more problems. However, experts say that most people would not make the best use of this extra time. They would be more likely to procrastinate and gravitate towards things that bring pleasure, such as eating, which could lead to increases in obesity.
Some people would still choose to sleep if they felt burned out and wanted to relax for a few hours. However, without the need to sleep, people would not dream.

There would be more opportunities to eat, which could lead to increases in obesity
If humans did not need to sleep, there would be more opportunities to eat, which could lead to an increase in obesity. This is because people would have eight more hours in the day to fill, and while they could theoretically spend this time exercising, humans tend to gravitate towards things that bring them pleasure. As Moloney says, "Even when people really do have the time to make healthy choices, a lot of times, most of us don't".
The extra time could also be spent working, and work hours would probably increase to 20 hours a day. People would have inexhaustible energy and strength, and would not need beds or permanent residences. They would be more nomadic and have more sex, including standing up and in orgies.
However, it is important to note that experts say most people would not make the best use of this extra time. While it is tempting to suggest that people would get more done and solve more problems, Moloney says, "It's really seductive to think we would all become smarter and more productive, but that's not necessarily the case".
In addition, not requiring sleep could have other health implications. Sleep problems have been linked with a number of health conditions, including obesity and heart disease. Even if there were a drug that allowed people to function without sleep, that would not necessarily take away the risk of these other health conditions linked with a lack of sleep.

Humans would have developed night vision
If humans did not need to sleep, it is likely that we would have developed night vision. Electric lights are a recent invention in human history, and without the need for sleep, we would have had more time to adapt to our surroundings. We would have inexhaustible energy and strength, and would not require beds or permanent residences. We would be more nomadic, and would have more time to be productive or to procrastinate. However, experts say that most people would not make the best use of this extra time.
There could also be negative health implications. Sleep problems have been linked with a number of health conditions, including obesity and heart disease. With more time available, there would be more opportunities to eat, which could lead to increases in obesity. While there would also be more time to exercise, humans tend to gravitate towards things that bring pleasure.
Some people are researching methods to prevent sleep, such as a nasal spray with the hormone orexin-A, which reversed the consequences of sleep deprivation in trial monkeys. However, this is far from being a cure for sleep.
