Yesterday's โ5 ๐ฆ๐ข๐ง๐ฎ๐ญ๐๐ฌ ๐ฐ๐ข๐ญ๐กโฆโ conversation was with Dr Alexander Sweetman, a leading sleep researcher. Joining me was Dr Phyllis Murphie PhD from the AWAKE study research team.
We explored something that rarely reaches public awareness:
COMISA - where insomnia and obstructive sleep apnoea occur together.
COMISA is not rare. Research shows that when someone has OSA, 30โ50% will also have clinically significant insomnia symptoms, and the coexistence of both conditions leads to worse daytime functioning and poorer treatment adherence compared with either condition alone.
Key evidence: Sweetman et al., Sleep Medicine Reviews (2021) and Sweetman et al., Sleep (2019).
This is one of the reasons why we are running AWAKE Check โ a national study to understand how many people in the UK have symptoms consistent with insomnia, OSA risk, or both.
Free, Fast (just five minutes), Science-based, Confidential, Anonymous (unless you want your results emailed to you).

For anyone struggling with insomnia symptoms (lying in bed too long, or trying to sleep at the wrong time), Alex also shared Bedtime Window, a simple evidence-based tool to help identify your personal sleep opportunity based on circadian timing:
