According to a new study, temperatures going higher constantly will cost humans 50 to 58 hours of sleep per person per year by the end of this century. This means, about 10 minutes of sleep loss will happen per night due to rising night temperatures.
The study has been published in the journal One Earth. It is based on the data collected from wearables, of more than 47,000 people in 68 countries between September 2015 and October 2017.
The co-author of the study Kelton Minor told that, “We found that nights that were randomly warmer than average eroded human sleep duration within individuals globally,” and Denmark based student in planetary social and behavioral data science at the University of Copenhagen further said that, “We estimated that people slept less and the probability of having a short night of sleep increased as nights became hotter,”
Heat adversely impacts sleep as the person’s body temperature must fall in order to fall asleep. Human body sheds heat when we go to sleep. But that will become harder as temperature rises, the study said.
Lack of sleep has a lot of potential health implications, including heart disease and health problems. According to the Washington-based National Sleep Foundation, adults should get seven to nine hours of sleep.Source: ndtv.com
