Health experts and public officials are advising residents across the U.S. and Europe on how to survive extreme heat without air conditioning.
These guidelines are critical because dangerous heat waves pose serious health risks, particularly for vulnerable populations who lack access to mechanical cooling systems [1].
Public officials suggest that those without home cooling should seek out air-conditioned public venues. These locations include movie theaters, malls, libraries, and designated community cooling centers [2]. "If you don't have air conditioning, find public places that do, including movie theaters, malls and libraries," Boston Herald staff said [2].
At home, the use of fans and evaporative coolers can provide relief, though their effectiveness depends on the environment. Evaporative or "swamp" coolers are useful in dry heat, but they can increase humidity and make it more difficult to cool down in damp conditions [2].
Experts also warn that fans are not always a safe solution. The MSN Health editorial team said, "Fans can cool you down or make dangerous heat worse. Learn when moving air stops being effective."
To manage indoor temperatures, officials recommend creating a cool sleeping area and utilizing simple home measures to block heat. These strategies aim to lower the risk of heat-related illnesses during the current weather patterns reported on June 30, 2026 [1].
“Dangerous heat waves pose serious health risks, especially for people without air conditioning.”
The emphasis on public cooling centers and behavioral adjustments highlights a significant gap in infrastructure and climate resilience. As heat waves become more frequent across the U.S. and Europe, the reliance on public libraries and malls as emergency cooling stations underscores the urgent need for systemic urban cooling solutions to protect those in lower-income housing.
