Daylight Savings Time may affect your body

(KYMA, KECY/CNN) - Daylight Savings time returns on Sunday, March 13 and that means turning clocks ahead by one hour but it can also affect sleep patterns.

"The inside clock, the clock inside our brain that regulates sleep and wakefulness, is typically a very reliable, periodic process and having just a one hour shift can actually affect us pretty significantly," said Sleep Specialist Dr. Nancy Foldvary.

A time change can affect your body by making it more vulnerable to a stroke or at the very least, make you less alert while driving.

“All of us have our own vulnerability to circadian rhythm changes. Some of us can manage in very difficult situations when our sleep structure changes and others cannot," explained Dr. Foldvary.

Rest should be planned ahead when Daylight Savings Time is about to happen.
