We all sleep – some of us better than others. Heading off to bed is a vital activity we all undertake every day. In fact, by the time we pass on, we will have spent an average of one-third of our lives sleeping. Sure, it may seem like a bit of a waste. After all, couldn’t we use all that time to be doing something productive? The answer is quite simply ‘No.’ It turns out that sleep is a vital activity that our body needs. It does far more than simply rest our muscles and bones for the coming day. In fact, a number of functions happen that play a vital role in our health. Of course, there are also other things our body does which aren’t vital – but they can provide clues about how stressed out we are or what we’re worried about. Stick around and find out what your body is doing while you sleep. Who knows, you may just learn a thing or two to make your sleep a little more relaxing.
