If you meet the criteria for insomnia then usually you can’t get to sleep or you can’t maintain the sleep. This has happened for longer than three months and you are struggling with this in day-to-day life.
If it’s affecting you in day-to-day life then that is a good indicator that you have some sort of insomnia.
It’s very easy to think that these problems are down to complex, mysterious bodily issues that we can’t control because it seems that we’ve found a cause that we can’t do anything about because it’s out of our control.
Yet, the reality is usually that factors which disrupt our sleep do have the ability to change our behaviours and make us sleep better. Even if it was caused by something very physical or chemical or hormonal, we can still do something about it.
At the end of the day, something might wake you in the night or you cannot get to sleep in the first instant but it shouldn’t be keeping you awake. If you are not sleeping it means the drive to sleep is not there and you need to build that drive up.
There is only one way to do that and that is with your behaviours. If you can change your behaviours and build your sleep drive, you can override the things that are making your sleep worse.
