Global mean temperatures set a new record in 2023, with nighttime temperatures increasing faster than daytime. The result is more sleepless nights, according to a study from Climate Central.

The study reports that hot nights make it harder for people to recover from the heat of the day, with wide-reaching and severe consequences including increased mortality risks. “A lack of quality sleep can have a range of associated impacts, including increasing the risk of many physical and mental health problems, impairing cognitive functions, negatively affecting children’s brain development, learning and school performance, and making workplace accidents more likely.”

Other studies show that increased evening temperatures reduce the natural drop in body temperatures, reduce time in deep and REM sleep, and leave us tired and groggy in the morning.
