How climate change can affect sleep

Sleep is extremely important for humans to remain healthy. Nick Obradovich, a postdoctoral fellow at Harvard's Kennedy School of Government and a research scientist at the MIT Media Lab, conducted a study based on data collected by the Centers for Disease Control and Prevention from 765,000 U.S. residents between 2002 and 2011 who responded to a public health survey. Obradovich combined the data with self-reported data of the respondents about their sleep. He found that an increase in temperature led to insufficient sleep. An increase of 1 degree Celsius at night time led to three nights of insufficient sleep per 100 individuals per month. By 2050, climate change could cost millions of people additional nights of insufficient sleep per year. This is the first study to highlight the effect of climate change and global warming on sleeping patterns of humans.
