Public cooling centers are recommended for those without access to air-conditioning.
•
At home cooling reduces risk of SARS-COV-2 transmission among vulnerable individuals.
•
Fan-use with water spraying gives effective cooling 100% of time in 80 of 105 US cities.
•
In only 10 of 105 cities fan-use with water spraying is not effective >0.5% summer days.

Alternative COVID-compatible cooling methods must be found for Southwest US states.
Abstract
Current public health guidance designed to protect individuals against extreme heat and the ongoing COVID-19 pandemic is seemingly discordant, yet during the northern hemisphere summer, we are faced with the imminent threat of their simultaneous existence. Here we examine the environmental limits of electric fan-use in the context of the United States summer as a potential stay-at-home cooling strategy that aligns with existing efforts to mitigate the spread of SARS-COV-2.
