Dermot Murnaghan & Circadian Rhythms



Metro came through for me again today, this time with their '60-second interview' column, a peek into the life of a minor celebrity that I today enjoyed whilst trying not to look at a businessman of a certain age talking to himself (no, there was no Bluetooth headset, and even so, he wasn't saying words). It featured breezy newscaster and official Dullest Man in Britain, Dermot Murnaghan, talking about how he's gone to Sky News from the BBC so he can get up two hours later, which shows refreshing honesty, as well as possibly suggesting that Derm's lost his zest for news.

Anyway, he backs up his flagrant laziness by claiming that he was having to get up at 3.45am, which is 'when your Circadian rhythms are at their lowest'. Circadian rhythms? Now the only time I'd heard this phrase before was in an REM song, and I mistook it for 'cicadian rhythms' as in 'rhythms made by cicadas', which I took to mean fast and high-pitched, like the theme to Alvin and the Chipmunks. But a quick scoot through - you guessed it - Wikipedia, has informed me that is in fact a fancy term for your body clock, i.e. a 24-hour biological cycle, present in animals and plants as well as humans, which is constant and unaffected by temperature change but does respond to external stimulus, hence your body clock slowly adjusts when you take a plane into a different time zone.

So Derm wasn't talking turkey, although his claim that 3.45 appears to be a fabrication; the link above claims that it is in fact 2am, although it does also state that 8.30am is peak time for bowel movement. When you consider that Murnaghan is usually introducing the weather at this point, it's a horrifying thought. Maybe that's why he's starting later. Anyway, according to the afprementioned circadian doodle I'm six minutes away from a sweet shot of melatonin, which should leave me feeling nicely toasted, ready for action in eleven-and-a-half hours' time...
