What You'll Learn

Humans would have inexhaustible energy and strength
If humans didn't need to eat, sleep or drink, they would have inexhaustible energy and strength. They would never need to rest, and would be able to work 24/7 for their entire lives. This would mean that people would have much more time on their hands, and science would progress even faster than it has in the real world.
However, some people argue that without the need to sleep, humans would burn out quickly. Sleep gives us a much-needed break, and without it, people might want to close their eyes and let the world flow around them, but be unable to do so.
Not requiring sleep would also have an impact on human sex lives. They would be more nomadic, and would have sex standing up instead of in bed. Orgies would be more common, since couples wouldn't retire to their own beds and homes as often.
Not requiring sleep would also have an impact on human evolution. Since electric lights are a recent thing in human history, it is likely that humans would have developed night vision. Without needing to sleep, humans wouldn't require beds or permanent residences.

People would be more scientifically-minded
If humans didn't need to eat, sleep or drink, they would have more time on their hands. This would mean that people would be more scientifically-minded. Without the need to sleep, humans would have inexhaustible energy and strength. They would not need beds or permanent residences and would be more nomadic.
People would be more empirically-minded than fantasy-oriented, which would lead them to be more scientifically inclined. With more time on their hands, science would progress even faster than it has in the real world.
However, some people argue that without the break that sleep provides, humans would burn out quickly and the suicide rate would increase.
If humans didn't need to eat or drink, they would not need to spend time preparing and consuming food and drink. They would also not need to go to the toilet, which would free up even more time. This extra time could be spent pursuing scientific interests and endeavours.
Overall, if humans didn't need to eat, sleep or drink, they would have more time and energy to devote to scientific pursuits, and would likely be more scientifically-minded as a result.

Humans would be more nomadic
If humans didn't need to eat, sleep or drink, they would be more nomadic. Without the need to eat or drink, humans would no longer need to be tied to a specific location to find food and water. They could roam freely without worrying about their basic survival needs. This would likely lead to a more nomadic lifestyle, with people exploring new places and seeking out new experiences.
Additionally, the need for sleep often limits our ability to travel and explore. Without the need for sleep, humans could travel and explore continuously without needing to stop and rest. This would further encourage a nomadic lifestyle, as people could easily cover long distances without the constraint of needing to sleep.
Furthermore, the absence of the need for sleep would also impact our energy levels and productivity. With inexhaustible energy, people could engage in continuous activities without feeling tired or needing to rest. This increased energy and productivity could further enable a nomadic lifestyle, as individuals could sustain prolonged periods of travel and exploration without fatigue.
However, it is important to consider the potential drawbacks of a world where humans don't need to eat, sleep or drink. While a nomadic lifestyle may be appealing to some, the lack of sleep could have negative consequences. Sleep provides us with a much-needed break and allows our bodies and minds to rest and recover. Without sleep, people may experience increased stress and fatigue, impacting their overall well-being.
In conclusion, if humans didn't need to eat, sleep or drink, it is likely that they would become more nomadic. The freedom from the constraints of food, water and sleep would enable people to travel and explore without limitations. However, it is important to consider the potential negative impacts on health and well-being that may arise from the absence of these basic human needs.

Religion would be stifled
If humans didn't need to eat, sleep or drink, religion would be stifled. Without the need for sleep, people wouldn't dream. Without dreaming, they wouldn't imagine their dead ancestors are still alive in a spirit world. This would stifle the development of religion. People would be more empirically-minded than fantasy-oriented, leading them to be more scientifically-inclined. With more time on their hands, science would progress even faster than it has in the real world.
People would also have more time to work, which would be good for the economy. However, this would also mean that stress levels would be through the roof, and mental health issues would be even more prevalent than they already are. Work and school hours would be much longer, and people would overall feel like they didn't relax enough.
Without the need for food or water, people would be immortal. This would also have a huge impact on religion, as people would no longer fear death. People might also question why they have inexhaustible energy and never need to sleep, and wonder if this is a sign that they are designed rather than the product of evolution.
