By Motoko Rich and Josephine de La Bruyère Reporting from Agrigento, Sicily September 3, 2026 Domenico Rizzo, a 40-year-old baker in Sicily, spent years sweating out stifling Italian summers without air-conditioning. He feared the cold air would make his muscles ache and dry out his bread. Three years ago, he finally gave in and bought a unit to help dehumidify his bakery. At home, he now relies on air-conditioning at night to recover after working next to hot ovens all day. Even though he complains that the chilled air hurts his neck and shoulders, he admits that it has become impossible to live without it. For generations, Italians shunned air-conditioning as a threat to their health. Many held a deep belief in the danger of a colpo d’aria, or a “blast of air,” which was thought to cause neck pain, headaches, muscle cramps, and respiratory problems. Medical professionals agree that sudden temperature shifts and direct cold air can dry out sinuses or cause muscle spasms. However, health experts also emphasize that as extreme heat waves become more frequent, the risks of heat-related illness and heat stroke far outweigh the discomforts of cold air. Rising temperatures across Europe are forcing a major cultural shift in a country where people traditionally relied on open windows, electric fans, and outdoor breezes. Government statistics show that 56 percent of Italian households had installed air-conditioning by 2024, up from under 30 percent in 2013. In warmer southern regions like Sicily, adoption has soared, with roughly three out of four households now using cooling units. Falling prices have made this transition much easier. Two decades ago, an air-conditioner was a luxury item costing nearly $1,800. Today, an influx of efficient models allows consumers to purchase units in electronics stores or supermarkets for under $350. Emilia Pisciotto, a 65-year-old bar owner in Agrigento, grew up without air-conditioning and still dislikes how it affects her sinuses. Yet, as recent summers have brought overwhelming heat, she acknowledges that cooling units are no longer optional because the heat has made it difficult to breathe. However, widespread air-conditioning brings serious financial and environmental drawbacks. Increased electricity use drove average summer utility bills up by 25 percent between 2021 and 2024. Environmental experts also describe air-conditioning as a form of “maladaptation”—a short-term fix that actually worsens the long-term problem. Running millions of cooling units strains local power grids and produces carbon emissions that drive global temperatures even higher. To balance these challenges, some community leaders are looking toward natural solutions. In Agrigento, city officials plan to plant 10,000 trees and install solar panels on public buildings to cool urban spaces naturally and generate clean energy. While a few traditional holdouts still prefer light clothing and natural airflow over artificial cooling, rising temperatures mean the vast majority of Italians are accepting air-conditioning as an unavoidable part of daily life.   Type your one-paragraph summary below:
