Global warming will reduce the duration of sleep

Scientists have reported that rising ambient temperatures due to anthropogenic global warming are negatively affecting the sleep of people around the world and can reduce it. This is reported in the article published in One Earth magazine.

The researchers analyzed data collected from sleep tracking bracelets from more than 47,000 adults in 68 countries, covering every continent except Antarctica.

By 2099, temperatures slightly above the optimum could result in 50 to 58 hours of sleep loss per person per year, according to the researchers. At the same time, the effect of temperature on the quality of sleep is significantly greater in residents of low-income countries, as well as in older people and women.

Hot days are known to increase deaths and hospitalizations and impair human performance, but the biological and behavioral mechanisms underlying these effects are not fully understood. The subjective quality of sleep decreases during periods of hot weather, but it remains unclear how temperature fluctuations can objectively affect sleep in people living in different climates.
