Why do we all need to sleep? To take rest?

Question

Why? Perhaps it's kinda odd, but wouldn't it be much better for our civilization if human-being does not need to sleep? At least, we'll gain more more progress and development right now... am I right here?

Answer 1

True... but every moment we move, we tear down muscles. At night, while we sleep, our bodies finally get the chance to rebuild itself. Our bodies are assaulted at every instant by poisons, bacteria, viruses, and infections, and during the day, we spend our immune system's resources fighting them. While we sleep, we are able to 'restock' for tomorrow's assault. Our minds are barraged from input from 5 senses, as well as constantly suffering from usage from thoughts, logic, creativity, and memories. While we sleep, our mind is finally able to 'defragment' itself (to put it in computer terms), and take what's in short term memory, and place it into long-term memory, or discard it altogether if it deems it unimportant to you.

Civilization as a whole would indeed benefit if mankind would not sleep... that is... for a single day. Beyond that, individuals would suffer from weakness, incoherency (eventually to the point of suffering from delusions, hallucinations, and hysteria), illness, and lack of energy.

Now, if you could find a way to provide a constant source of energy, nano-technology to rebuild every muscle in the body at a constant rate, mental stimulants to focus the mind (and do all the memory-sorting housekeeping), and a hefty supply of antibodies... then I suppose sleep would be unnecessary.

But I suppose I'd pass out from the pain of having so many needles injected into me to get all those drugs to work.

Sleep is just that much more convienant.

Answer 2

When many people are faced by a stressful situation at work, they respond with complete commitment, by working intensely hard at resolving it. To do this, they may work all hours, cancel vacations and cut back on sleep, all to make more time to tackle the problem.

If this is short-lived, then negative effects will be minimal and success will often be spectacular. However, if this level of hard work is sustained for a long time without relief, people increasingly risk ill-health and burnout.

We rest and sleep because we need to.

Rest is what we do to let stress subside. Rest at the end of a day, and at the end of a week, helps us to calm down.

Doing fun things that we enjoy in our leisure time compensates us for the stress we experience at work, bringing some balance back into life. This is particularly important if we routinely experience unpleasant levels of stress.

On average, people need around eight hours sleep a night (although this can vary between three hours and eleven hours, depending on the person and his or her age).

If we are regularly short of sleep, then our concentration and our effectiveness suffer and our energy levels decline. We have all seen and experienced this.

This diminishes our effectiveness in our job, and can therefore increase stress: As our concentration wanders, we start to make mistakes. As our energy declines, we become less proactive in what we do, reducing our control over events. This means that a situation that is already difficult and stressful can become worse, needing even more sacrifice to bring it back under control.

Think of your Brain or your mind as a room. During the day when you are fully cognisant, your mind becomes cluttered with thoughts and experiences, as a room will become cluttered with mess. Because your mind is being constantly bombarded by new thoughts, and concepts, unlike a room, it cant arrange and organize everything automatically. When you sleep, this is time for your mind to organize/clean itself. Putting away thoughts and memories from earlier into the memory, rearranging neurons & such. Sometimes, this mess spills out of the room - which causes a dream to occur. This is also why when you do not get enough sleep, memories begin to run together and functioning is hindered - like a messy room, you cant operate as effectively as you would if it was clean. Your papers get mixed up, etc. When you wake up the next morning from a full sleep, your mind is ready to handle all that is about to come its way.

Answer 4

Sleep is a time for our bodies to recover from the stress and damage we do to it during the day. It allows the muscles to regrow and the mind to reboot. If you ever gone without sleep for more then 24 hours you being to stress out and everyone knows that stress is a big factor to illness. also your body will begin to feel like a mess because it cant regenerate without rest. That's why some people who can't sleep are so stress.

Answer 5

In the human being as with every creature and living thing, down time is needed to grow and repair cells. That is the reason it was built into the mix. If you will notice, insomnia makes for a lack of good health it also makes people lose judgment and become grouchy. Progress and development depend on rest and relaxation. You are very wrong in thinking it is not important.

Answer 6

People that deprive themselves of sleep, begin to hallucenate. They see and hear things that arent really there, and act irrationally. Sleep is how your brain can reorganize all of its thoughts, kinda like when you shut down your computer. so, when you wake up your mental capacity is at its best. After three days of no sleep, it becomes difficult for an intelligent person to make what seems to be simple decisions about things. And it is almost impossible to get organized. Remembering where you put your keys can be very difficult. When you are awake for days at a time, they all seem to blend together so to recall what happened on a specific day is difficult because you have no real way to distinguish when one day ended and one began.

Answer 7

Why Do We Need Rest

Answer 8

You need to sleep because that is when the body repairs itself and grows the most. It is also the time that your brain uses to file everything that happened to you during that day, it process everything into "file like catagories"; that way you can retrieve it for future use. Example: You study for a test; what you read is processed and stored during sleep, then when you take a test your brain goes through the files for the answere.
We would not be more productive with-out sleep; in fact we would be less productive because our bodies would burn-out!

Answer 9

If we didn't sleep we would all be like zombies, unable to function. A body needs rest otherwise it basically goes out of control

Answer 10

No you don't burn more by doing nothing, because your body burns a minimum number of calories per day, and that is if you just sleep and rest. If you were to exercise you would burn the minimum number in addition to however many calories you have burned doing the exercises. At least that is the case if my 9th grade teen health book was correct...
