Climate Change Contributes to Sleep Loss Across U.S. Cities
A recent analysis by Climate Central reveals that climate change is causing significant sleep loss due to rising nighttime temperatures. Between 2020 and 2025, people in 253 U.S. cities lost an average of 36 hours of sleep annually, with about 13% of this loss attributed to human-caused climate change. The most affected states include Arizona, California, Florida, and Nevada. The study highlights the growing impact of climate change on sleep quality, as warmer nights disrupt the body's cooling process, leading to shorter sleep duration and reduced quality.
