Hotter Nights, Brought on by Climate Change, Pose More Health Threats
University of Washington Department of Global Health Professor and epidemiologist, Kristie Ebi, claims that “If it doesn’t cool down at night, then your core body temperature can’t really get back to what is normal for you. You’re starting the next morning with a higher baseline.” That’s why death rates start to increase after about 24 hours during heat waves. “It’s not the instantaneous exposure; it’s the buildup over the course of a day, not getting relief at night. That starts affecting the cells and organs,” Ebi says.
