Key takeaways:
- Nights, whose temperature remains below 20 C, will set to more than quadruple over the following 60 years.
- A study saw the average person now loses an assessed 40 hours of sleep yearly due to extreme nighttime temperatures.
Montrealers having a problem sleeping at night when it’s warmer than average are not alone.
According to a study issued in the environment-focused scientific journal One Earth, warmer temperatures now impact the average individual’s ability to fall and stay asleep.
“People napped less, and the probability of having a shorter night of sleep increased as the temperatures became warmer,” stated Kelton Minor, the study’s principal author and a Ph.D. student at the University of Copenhagen’s Center for Social Data Science. The study followed 47,000 people in 68 nations using unique bracelets and combined their sleep data with each participant’s local climate and weather data.
The study comes as climate data reveals that — even with conservative estimates regarding greenhouse gas emissions — the number of nights each year where the temperature will not fall below 20 C is anticipated to more than quadruple over the following 60 years in some areas of Canada.

Montreal, for instance, has historically averaged approximately eight of these nights each year, according to the Climate Atlas of Canada. But over the next 30 years, that number could grow to anywhere between 19 and 22 nights with such temperatures, then between 28 and 45 in the following thirty years.
The project also indicates that heat waves in Montreal, defined as straight days when the temperature climbs past 30 C, will rise from lasting an average of three days in 2005 to as long as eight days by 2080.
Minor’s study also indicates that the perfect sleep temperature for the average human could be around or below 5 C, so sleep could be seriously impacted in the summer months for those without air conditioning, and electricity bills will probably increase for those who do.
