What’s the scientific reason behind wanting to sleep?

As long as I stay hydrated and eating to get enough energy I don’t see why I shouldn’t be able to go on forever or for a very long time (like a phone a charging while being used)

    science of course is being unnecessarily cryptic

    but considering you start to hallucinate when you don't sleep, it's required for brain maintenance

    the brain does rhythmic hops when you sleep. seems to be like maintenance work of some sort

    I also had an idea that it has to do with toxic metabolites. as you think your brain generates toxic waste, and it's possible when you're awake it can't clean up all of it and needs a shutdown process. I can't remember now why I came to that conclusion. I was doing some neurotransmitter and neuron metabolism research at the time but I can't remember the specifics now, sigh...

    schizophrenia (which is what happens when you're sleep deprived) to me seems like your brain having TOO many connections though, not that you lack connections. so maybe sleep prunes neuronal connections, and not necessarily reinforces existing ones. probably it does both

    question is, which does it decide to keep or abandon? 🤔🤷

    Sleep is a crucial aspect of our overall health and well-being. It plays a vital role in various physiological and cognitive functions, including:

    1. **Restoration and Repair:** During sleep, the body undergoes several important processes, such as tissue repair, muscle growth, and the release of growth hormones. These processes help the body recover from the day's activities and maintain overall health.

    2. **Memory Consolidation:** Sleep plays a significant role in memory consolidation. During the different stages of sleep, the brain processes and stores information gathered during the day. This aids in learning, problem-solving, and overall cognitive function.

    3. **Emotional Regulation:** Adequate sleep is essential for emotional health and regulation. Lack of sleep can lead to irritability, mood swings, and difficulty managing stress and emotions.

    4. **Immune Function:** Sleep is crucial for a healthy immune system. During sleep, the body produces and releases cytokines

    , which are proteins that help regulate the immune response. Insufficient sleep can weaken the immune system and make individuals more susceptible to illnesses.

    5. **Brain Function:** Sleep is essential for optimal brain function. It helps to regulate neurotransmitters, promote neural growth, and maintain cognitive function, including concentration, decision-making, and problem-solving.

    Overall, getting enough quality sleep is crucial for maintaining physical health, cognitive function, and emotional well-being. It is an essential foundation for overall health and should be prioritized in daily routines.

    @tosensei 's response is the case for biological beings.
    But you can see the same thing on machines. If a car moves continuously stopping only to refuel, it won't last long.
    Even formula one cars, that are always the best built machines with the best parts, best fuel, best calibration and always on the best road conditions, require maintenance on the middle of a race.
    The engines would just melt down, otherwise.

    Your body doesn't need sleep. Your muscles can probably keep doing their thing 24/7.

    It's your mind that needs sleep.

    Despite all the science links people are posting and the AI-bot's explanation, if you start looking through the literature, no one really knows why we need sleep. Everyone is really just guessing.
