Sleeping is a major part of our lives. You would think given how important sleeping is, it would be an easy thing to do, but sometimes that’s not the case. That’s because our modern lifestyles can sometimes mess with our natural sleep systems. For this reason, it is important to learn about how to get a good night’s sleep. However, to do that, we first need to look at how our bodies encourage us to sleep.
The human body has its own natural body clock called the circadian rhythm. Among other things, the circadian rhythm is responsible for telling us when we should sleep and when we should wake. It usually does this by sensing when it is light outside and when it is dark. Our circadian rhythms keep us awake and alert during the day and produce melatonin when it gets dark to make us sleepy.
