Night becomes the new morning: extreme heat is shifting daily schedules
With 45°C in the shade and a heat index of 70°C in the sun, more and more people are flipping their routines: sleeping by day and living by night. Extreme heat is rewriting daily schedules.

When the day burns, the night comes alive: how humans adapt to extreme heat
With thermometers reading over 45 degrees in the shade and heat indexes approaching 70 under direct sunlight, a growing share of the population is abandoning the conventional daytime schedule. What used to be a rarity —staying up until dawn— is becoming a climate survival strategy.
The accounts of those already practicing this "shift change" are telling: while the sun beats down, life grinds to a halt; as soon as night falls, animal and human activity picks back up. Cats, dogs, rodents and nocturnal birds dominate the soundscape, and humans join in with activities ranging from remote work in the small hours to outdoor leisure.
Heat as the driver of changing habits
Daytime climate confinement is pushing many people to invert their sleep cycles. "I'd rather go to bed in the early morning and wake up at 1 or 2 pm," explains someone who has already normalized it. The midday siesta, once an occasional recourse, has become routine for those who can afford flexible hours, especially among remote workers and civil servants with lenient schedules.
The subjective experience of global warming no longer needs charts: anyone who lives through a summer in Alicante or somewhere similar feels it in their own skin. The nighttime mugginess offers little relief, but at least the absence of direct sunlight allows for some outdoor activity.
Farewell to the early bird?
The saying "the early bird catches the worm" crashes against climate reality. With temperatures already hitting 45 degrees by mid-morning, getting up early no longer makes economic or productive sense. Those who rise early, without air conditioning, face hours of unbearable heat before noon.
The irony is immediate: some point out that the saying was coined in colder times, and that today "the night owl gets the worm" would be more fitting.
Adapting to this new rhythm has obvious limits: not everyone can choose when to work, and the electricity bill from keeping the air conditioning on all night is no small matter. But as long as heatwaves keep intensifying, the night will continue gaining ground as the only livable time of day.
