By the end of this century (2099) warm temperatures will cost people 50 to 58 hours of sleep per year, a new study claims. Loss of sleep – about 10 minutes per night – is caused by an increase in nighttime temperatures due to climate change.
The study was published in the journal One world. It is based on data collected by wristbands and smart watches that measure the sleep duration of more than 47,000 people in 68 countries between September 2015 and October 2017.
“We found that the nights were randomly warmer than the average time people slept around the world,” said study co-author Kelton Minor. Health Day News.
The Danish-based student of Planetary Social and Behavioral Data Science at the University of Copenhagen added:
With mercury hovering around 50 degrees Celsius last week, people in many parts of India are facing extreme temperatures. Not only day but also night has become hot due to heat wave.
Researchers who conducted the study said that if the nighttime temperature outside the minimum level due to climate change exceeds the minimum level, the chances of getting less than seven hours of sleep increase by 3.5 percent.
Alex Agostini, a lecturer in the Department of Justice and Social Studies at the University of South Australia in Adelaide, said “3.5% of sleep loss may initially appear as a small number, but it adds up.” CNN. He was not involved in the study.
Heat has an adverse effect on sleep because a person’s body temperature must be lowered in order to fall asleep. The human body heats up when we go to sleep. But as temperatures rise, it will become harder, the study said.
Lack of sleep has many potential health effects, including heart disease and health problems. According to the Washington-based National Sleep Foundation, adults should get seven to nine hours of sleep.
