Cf. ORIGINS ( A Skeptic's Guide to the Creation of Life on Earth ) by Richard Shapiro, Chapter 11, for an account of the Seventh International Conference on the Origin of Life held in Mainz, Germany in 1983. My favorite passage:
"I found that the temperature bothered me mostly at night, in my hotel room. There was no air conditioning, so I had to keep the windows wide open. This in turn brougth in traffic noises, and the heat-and-noise combinations often kept me awake. Ironically, I had little difficulty falling asleep in the lecture hall during the day, even though it was also hot and noisy."

Classic jetlag!
