How did the ancient Romans sleep on hot nights?

No air conditioning, no fans, no ice — just a Roman body trying to cool down enough to fall asleep in August. This video explores how Romans handled brutally hot nights: sleeping on rooftop solaria to escape trapped indoor heat, the impluvium's evaporative cooling effect on a shaded atrium, why upper-floor insula apartments were often the hottest and cheapest rooms in the city, wet cloth and standing water jars used as primitive evaporative coolers, and why sleep itself likely broke into two phases, tracking temperature rather than darkness. We also cover why an entire household never slept at the same depth at once, and how an older family member's light, broken sleep quietly functioned as a household's night watch. No invented facts — every claim is grounded in Roman sources, archaeology, or comparative historical research. 💬 We complain about phone screens keeping us up — Romans dealt with brick walls holding heat, no fans, and mosquitoes finding them within minutes.
