If current trends continue, we could be missing out on an hour of sleep a week by the end of the century <\/strong><\/p>\n\n

Rising temperatures due to climate change are negatively impacting our sleep, a study carried out by a team at the University of Copenhagen has found. <\/p>\n\n

The findings suggest that by the year 2099, higher temperatures will lead to us losing 50 to 58 hours of sleep per year \u2013 roughly one hour per week. <\/p>\n\n

To make the discovery, the team analysed data collected from accelerometer-based sleep-tracking wristbands that had been shown to match up with self-reported measures of wakefulness and sleep in previous studies. <\/p>\n\n

The dataset included seven million individual records taken from more than 47,000 adults from 68 countries across all continents except for Antarctica. <\/p>\n\n

Hot weather can rob us of our sleep <\/figcaption><\/figure><\/div>\n\n

The team found that on nights when the ambient temperature exceeded 30\u02daC, people slept 14 minutes less on average. The likelihood of someone getting less than the recommended seven hours of sleep a night also increased as temperatures rose. <\/p>\n\n

\u201cIn this study, we provide the first planetary-scale evidence that warmer-than-average temperatures erode human sleep. We show that this erosion occurs primarily by delaying when people fall asleep and by advancing when they wake up during hot weather,\u201d said first author Kelton Minor of the University of Copenhagen. <\/p>\n\n

The researchers also found that the effect is even more pronounced for residents from lower-income countries, as well as older adults and females. <\/p>\n\n

Every night, when we go to sleep, our bodies shed heat into the surrounding environment by dilating our blood vessels and increasing blood flow to our hands and feet. In order for this process to occur efficiently, the surrounding environment needs to be cooler than our bodies, otherwise our sleep becomes interrupted. <\/p>\n\n

The researchers now hope to expand the study to take in data from an even larger number of participants, especially more vulnerable populations such as those who live in the world\u2019s hottest and poorest regions. <\/p>\n\n

\u201cIn order to make informed climate policy decisions moving forward, we need to better account for the full spectrum of plausible future climate impacts extending from today\u2019s societal greenhouse gas emissions choices,\u201d said Minor.<\/p>\n\n
