Deep sleep vs. Light sleep

[Nayler]

For some reason I seem to flip-flop between getting lots of light sleep and not a lot of deep sleep to getting enough deep sleep but minimal light sleep. This is my record for a week of sleep:

Sorry if the formatting is gross or there are duplicates, this post creator is terrible to work.

Basically from this you can see that when I get lots of light sleep my deep sleep suffers. When I get more deep sleep, I barely break the light sleep amount. Is there a reason for this or is this normal? And what can I do to stabilise myself night to night?

Hi @Nayler,

Your post and screenshots make sense. When we deep sleep more, it has to come from somewhere--in this case from light sleep.

There is a sticky thread I started in this forum that covers many tips for improving deep sleep. Check it out for ideas.
