Melinda Jackson explains this familiar phenomena as
"We've been able to distract ourselves and busy ourselves during the day with work and activities and whatever we're doing. But at night it's often the first time that we've kind of allowed ourselves to stop and our brains are like, okay, now I can start doing stuff that I want to do, and then the thoughts just come."
A report from the sleep health foundation found that nearly 40% of Australians experienced inadequate sleep.

Sleep was different 100,000 years ago. You didn't just tuck yourself away for a number of hours and wake up pleasantly at the end of it. You are alert for whatever might come after you. We would have repeatedly woken up to quickly observe that we are still safe.
Dr Stan Rodski author of The Neuroscience of Excellent Sleep, suggests these cycles were approximately 90 minutes. We go and we go deep and we come out and we go back in and we go deep, but they get shallower as the night goes on until we fully wake up.
These cycles are why many of us wake up at various times in the night. It's actually a pretty normal thing.
The brain seeks patterns because it is its most efficient energy use. If it's got a pattern, it can do things easily and quickly. Author Rob Stones relates to this in aquiring the habit of resilience.
Sometimes it gets into a wrong pattern or a pattern that is not your optimal. The brain doesn't care if it is a good habit of a bad habit. That's a decision that occurs in the emotional parts of your brain. Hence try to regulate your circadian timing as best possible.

Hence a bath or a shower can help you sleep because afterwards your body is slightly cooler.
A nap cannot be longer than 30 minutes and is best between 2 PM and 4 PM. If you sleep for 35 minutes your brain will want you to finish the 90 minute cycle.
It is well established that stress and sleep are intimately connected. There's a lot of overlap between the neuro chemistry and the neural networks that are activated during the stress response, and the same networks that regulate our sleep as well.
Stress is considered to be the major precipitant of insomnia in most cases.
Sleep is just so fundamental to all elements of our health and well being. And it might be that you're able to cope at the moment with getting four or five hours of sleep and you're fine the next day, but sleep is also a risk factor for some forms of cancer, cardiovascular disease, diabetes, but more importantly, the risk of later anxiety and depression.
