Different questions. Different evidence.
A treatment guideline is not
a correlation study.
Before applying a finding to your own night, ask what was tested, in whom, and whether other studies found the same thing.
Clinical guideline · adults
What helps chronic insomnia?
The American Academy of Sleep Medicine recommends multicomponent CBT-I [1] for adults with chronic insomnia. Sleep hygiene alone is not recommended as the sole treatment.
This is guidance about treatment. It does not mean a diary or an app provides CBT-I.
Sleep studies · mixed findings
Does the lunar cycle matter?
A 2013 retrospective laboratory analysis [2] reported sleep differences around the full Moon. A 2014 analysis of three larger datasets [3] did not replicate the result.
These findings do not predict whether you will sleep poorly on a particular lunar night.
Observational research · limited
What about magnetic activity?
In a 2020 study of heart-rate variability [4], most relationships disappeared after accounting for dependence between measurements over time. The remaining effects were very small.
Heart-rate variability is not the same as insomnia or mood. This study cannot diagnose “storm sensitivity”.
