Rising Temperatures Erode Human Sleep Globally: Climate Change Sleep Crisis
How Is Climate Change Affecting Global Sleep Patterns?
Rising global temperatures due to climate change are significantly eroding human sleep duration worldwide, with this comprehensive analysis showing that people lose an average of 44 hours of sleep per year for each 1°C increase in nighttime temperature. The research, analyzing sleep data from 68 countries, reveals that warmer nights reduce sleep duration more than warmer days, with the greatest impacts on elderly populations, women, and residents of lower-income countries. By 2099, climate change could reduce global sleep by 50-58 hours annually per person, representing a major public health crisis that disproportionately affects the world’s most vulnerable populations.
