Sunday marked the start of daylight saving time. 

The clocks have "sprung forward" an hour to make use of the longer daylight. 

However, that change could have an impact on your sleep schedule and beyond. 

Dr. Alice Hoagland, a clinical psychologist with Rochester Regional Health, spoke to Spectrum News 1's Mercedes Williams about losing that extra hour and what happens to people's minds and bodies when their sleep schedule shifts.

"Daylight saving intrinsically is not convergent with your normal biological rhythm," Hoagland said. "You're just forcing yourself everyday to get shifted away from your biological rhythm. So, in general, in sleep medicine we recommend that we would ultimately that people stay on natural time not daylight saving time."

Hoagland also discusses the problems adolescents can face after a time change and what she would recommend for anyone to help reduce the impact of time changes.
