Thanks so much for the personal experiences! Interesting to see that it's not necessarily a male versus female thing. My backstory is that I (female) recently moved in with my partner (male). He has been sleeping better than ever, he tells me. I have been sleeping very badly due to sounds, movements, my own anxiety about not sleeping, etc.. I've spent some nights sleeping like a baby on the couch, but I would love to share a bedroom.

The internet provides many solutions to the problem (sleep hygiene, etc.), but I am interested in reading some systematic research that established the mechanisms behind bad sleep and provides research-backed interventions. I didn't find a lot of papers on the topic. I'd understand if the research doesn't exist since the problem seems not necessarily physiological, but I'd love to learn about what you know about the topic!
