2.4 billion people experience increased hot nights due to human-induced climate change, impacting health outcomes.

Human-induced climate change is significantly increasing hot nights for nearly one-third of the global population, affecting 2.4 billion people on average. High nighttime temperatures prevent body cooling and recovery from daytime heat, impacting health outcomes. Burning fossil fuels, such as coal, oil, and gas, releases climate-warming emissions into the atmosphere, causing rising nighttime temperatures. Warmer nighttime temperatures can harm sleep and reduce physical recovery from hot daytime temperatures, leading to increased risks of strokes, cardiovascular conditions, and mortality, particularly affecting the elderly and those on lower incomes.
