# The non linear relationship of sleep

The picture above shows a graph that is difficult to read. On the x-axes you can see my “perceived overall sleep quality”; a score I give (1-10) that combines the quality of the sleep, with my sleep duration subjectively. In the Z-axes you can find “Difficulty getting out of bed”. This is also a subjective score ranging from 1-10. On the Y-axes (the length of the bars), you can see the occurrences of how a combination between Y an Z took place. In the table below I plotted the same thing (more insightful but less pretty).

In the table you can clearly read the occurrences. The event that occurred the most (65 times) is a bad sleep quality (of 4), in combination of a hard difficulty with getting out of bed (7). That seems quite logical. When I sleep bad (4), I hardly can get out of bed (7). When I sleep good (7), I can also get quite easily out of bed (4), (54 occurrences). However, the weird thing is that it also occurs quite often that I sleep quite well (7), but still have a hard time getting out of bed (7). This occurred 42 times.

It seems that there are other factors manipulating this relation. For example, time of waking up, waking up of my partner, plans for the next day, etc. Life is quite complex, and that is what I want to point out with this blog. It is not just that easy that you sleep well, and get out of bed well. I’m sorry. I can “control” for these other factors, but the question is whether my mind does this as well in the morning. And the question is how many factors are manipulating the relationship. This problem seems multi-dimensional (multi-layered), and seems to have attractor states. If you want to know what I mean with this, please contact me.

While writing this, I found that I could better translate the occurrences into percentages, but to re-do this takes me too much time in relation to the (very) small audience who is going to read this.

Did you mean in relation to the “yet” very small audience?
Impressive work!
