The days are hot, but so are the nights. That's a problem, experts say
Experts warn that rising nighttime temperatures are becoming a significant health risk as the U.S. experiences prolonged heatwaves. The lack of overnight cooling prevents the body from recovering and places additional strain on energy infrastructure.
Why it matters
Increasingly warm nights exacerbate the health impacts of climate change, particularly for vulnerable populations without air conditioning.
Much of the U.S. is in the midst of dangerous and potentially record-breaking daytime temperatures as a heat dome has settled over the Midwest and the Atlantic Coast. But nighttime temperatures are staying unusually warm, too, raising the risk of heat exhaustion and heat stroke even higher, especially for people without access to air conditioning.
