“Carriers of the mutation have longer days than the planet gives them, so they are essentially playing catch-up for their entire lives,” says lead researcher Alina Patke from The Rockefeller University in New York.

Night owls who struggle to get enough sleep are often diagnosed at sleep clinics with delayed sleep phase disorder (DSPD), and researchers estimate that around 10 percent of the global population is affected by this condition.
