Climate change is costing the world nearly a week of sleep every year

Rising nighttime temperatures driven by climate change are robbing people of almost a full week of sleep each year, according to a new analysis.

The analysis, by US-based climate science organisation Climate Central, examined 1,338 cities worldwide and found that between 2020 and 2025, the average person lost nearly 56 hours of sleep per year due to high ambient nighttime temperatures.
