People talk about migraines on Twitter more on weekdays than weekends and holidays - and the peak time of day for the horrible headaches is 7 in the morning.
The working-day effect on migraines has been reported before - perhaps a reflection of stress or, less charitably, people wanting a day off work... although some people suffer weekend migraines.
Of the working week, Tuesdays saw the most migraines, while Fridays were the least bad. About 80% of Twitter migraine mentions came from women - which matches the fact that women are at higher risk.
In fact, an author of this study said in an email to me that it was actually inspired by one of my posts... but I'm aware that telling you that, combined with the previous post, means I'm in danger of blowing my own trumpet or 'disappearing up my own arse' as we say in the UK. So rest assured that this will be the last such self-referential piece for at least... a day or two.
