Scientists found global mean temperatures have risen by more 34 degrees Fahrenheit since 1850, setting a new record in 2023.
Ironically, it gets worse once the sun goes down.
Nighttime temperatures have increased even more rapidly than daytime temperatures as the world heats up, the study said.
Those hot and sleepless nights make it harder for people to recover from the heat of the day. And the effects could be deadly.
Hot nights led to a 50% increased mortality risk, the report said.
Sleep deprived nights also lead to an increase risk of both physical and mental health problems like brain development, learning and school performance.
