Hi, I'm going to be starting a study soon about the relationship between mental health and sleep hygiene (e.g. oversleeping, lack of sleep) and was wondering what angle to do it about? I have a few ideas...

- If there is a correlation between oversleeping/lack of sleep between different kinds of diagnoses (bipolar more likely to oversleep, bpd more likely to under-sleep)

- Or if age has a connection between those who sleep healthily and those who don't with mental illnesses?

- Correlation between suicidal ideation and oversleeping/not sleeping 


Yea my ideas are really shoddy right now so I'd love to hear some feedback and ideas on what to do this relation about...! Thank you, any help is extremely appreciated!
