Hot nights are linked to poorer sleep and health risks
Researchers say rising overnight temperatures are extending the period of heat stress and making it harder for people to recover while they sleep.
Scientists and health experts are warning that warmer nights are becoming a growing public health issue as heatwaves last longer and overnight temperatures stay high. The concern is that people lose the chance to cool down and sleep properly after hot days.
According to Euronews, researchers say the effects of heat are no longer limited to daytime discomfort. They point to hotter nights as a factor that can disrupt sleep and add strain to the body.
The report says the trend is part of a longer heat-stress season, with nights increasingly drawing attention because they can affect health even when people are indoors. Poor sleep is one of the main concerns raised by researchers.
The broader warning comes as climate-driven heat events continue to affect more places for longer periods each year, making nighttime temperatures an increasing focus for doctors and scientists.
