Zeitgeber (from the German for “time giver”) is any environmental cue that keeps circadian rhythms entrained by resetting the internal clocks that generate endogenous rhythms. Zeitgebers include light, food, noise, social interactions, and alarm clocks.
My zeitgebers are beschissen. It’s 6am, I tried to sleep some hours ago, but my delightful flatmate was snoring like a train, and my mind was wandering across to the wrong side of the tracks, and so, on the day that I put on a shirt and venture into Manchester to finally find a job, I shall not have had a wink of sleep.
But in other, better news, the Germans refer to a pimp-mobile as a Schlampenschlepper, which makes me strangely happy.
Time for tea, I think.
