Do you ever feel like your waking hours are over too fast?

Imagine if we could spend more time doing the things we love by dropping one inconvenient habit.

The need to sleep.

What a sleep even do besides stopping us being grumpy and tired?

And what would happen if you stopped sleeping altogether?

Let's find out now.

You're listening. You're listening. You're listening. You're to be amazed.

Humans spend about one-third of their lives catching Z's.

You may think of sleep as a time when your mind and body simply shuts off for a few hours.

In reality, sleep time is a surprisingly active period, which allows for essential processing

and regeneration.

Scientists are still figuring out why humans are programmed and need such lengthy rest periods

to function optimally, but it's vital for both mental and physical health. Indeed, sleep is

so vital that a severe lack of it can be incredibly harmful, even fatal. The most immediate

value of sleep is what it does for our cognitive abilities. While we're awake and going about our day,

busy neurons in the brain produce a byproduct called adenosine.

The buildup of adenosine in the brain is one factor that leads to our perception of being

tired, as it slows down neurons. During sleep, the body has a chance to clear this adenicine

buildup from the system, and as a result, we feel rested and alert. And if you ever wondered why coffee gives you

that amazing afternoon kick, caffeine temporarily prevents adenosine being absorbed by neurons,

reducing the feeling of tiredness. But our need for slumber goes a lot deeper than avoiding

sleepiness. A 2013 study led by Professor Mike and Nadergaard at the University of Rochester discovered a network of microscopic fluid-filled channels in rats' brains that flush out waste chemicals, like the aforementioned adenosine, using cerebro-spinal fluid. This process occurs mostly when the brain is in sleep mode. These channels have been named the
