All human beings need sleep. It’s as important to life as oxygen, food and water. You spend about a third of your life sleeping. That means that if you live up to a hundred years old, you’ll spend 33 years asleep. That’s a lot of time we’re wasting right? Imagine all the things you could do with that extra eight hours a night. You could hang out with friends, play games, learn new things.

Sleep is an essential part of our daily routine that is often overlooked. Getting enough sleep has numerous health benefits that can improve your overall quality of life. In this article, we will answer the top 5 frequently asked questions about sleep to help you understand the importance of sleep and how it can benefit your health.


Question concept.

Good question.

We still aren’t sure what exactly it is or why we need it, but scientists are trying hard to figure it out. Even if we don’t know everything, let’s talk about the one we know. First off, our brains act differently when we sleep. The millions of tiny cells in your brain called neurons, sends thousands of signals to each other each second.

Sometimes those signals line up into patterns, like waves of water on a beach. Different wave patterns in your brain represents different stages of sleep. When you first lay down in bed and try to fall asleep, your brain creates fast alpha waves, which are associated with relaxation. Once you start to dose off, your brain waves slow down. These are called theta waves, and they’re important for learning and memory. 

You’re still not very deeply asleep until you sink into what’s called slow wave sleep and boy are they slow. At this point, the waves are coming only about once per second. Now, you’re definitely asleep. If we need to do it every night, our brain must be doing something pretty important right? 

The weird thing is, even if we have theories, we still haven’t quite figured out where it came from – or why we need it.
