Climate change may prevent you from receiving a good night’s sleepAccording to a new Study,
Researchers link higher night temperatures to lower temperatures Sleep Decreased sleep time and quality – especially in people with chronic health conditions.
A new study from Scientist The University of Southern California found that hot weather can disrupt sleep in several ways, including preventing the body from cooling down, triggering a stress response, and reducing the time spent in deep sleep. rapid eye movement (REM) sleep.
The findings, published in the journal Environment Internationalsaid that a 10 degree Celsius increase in daytime temperature was associated with 2.19 minutes of sleep loss, while a 10 degree increase in nighttime temperature was associated with 2.63 minutes of sleep loss.
Rising temperatures are also associated with more disrupted sleep throughout the night and more time spent awake in bed.
“We already know that when there is extreme heat, more people die from heart disease and pulmonary disease. What will this mean for population health as global temperatures continue to rise?” said Jiawen Liao, PhD, postdoctoral research associate at the Keck School of Medicine of USC and first author of the study.
The study analyzed data from 14,232 US adults collected between 2010 and 2022. Researchers looked at participants’ demographic, socioeconomic and health information as well as their Fitbit data to evaluate more than 12 million nights of sleep.
They also examined eight million nights of data on sleep stages and how often sleep was interrupted, combining it with location and meteorological data to see whether sleep patterns were linked to changing temperatures.
The numbers were higher among women, people of Hispanic ethnicity, people with chronic diseases and people of low socioeconomic status, the study authors said.
They warned that poor sleep itself can increase the risk of a number of health problems, including cardiovascular and respiratory conditions and mental health concerns.
“It may seem like a small amount, but when it adds up over millions of people, the total impact is huge,” Mr Liao said.
“This work is an important step toward understanding how sleep is affected by environmental stressors like heat, which can increase the risk of disease and even death. If we can help people sleep better, we may be able to reduce disease and save lives.”
