Climate change that leads to warmer than normal nights can do major harm to human sleep researchers say. The findings showed that abnormal increases in night temperature by 1 degree Celsius can translate to three nights of insufficient sleep per 100 individuals per month in the US. If climate change is not addressed warmer temperatures could cause six additional nights of insufficient sleep per 100 individuals by 2050 and approximately 14 extra nights per 100 by 2099 the researchers said. Sleep has been well-established as a critical component of human health. Too little sleep can make a person more susceptible
