A local sleep expert said it is typical for people to feel irritable, tired, and unfocused during the first few days after the clock changes for daylight saving time.
Daylight Saving Time returned Sunday. Cookeville Regional Sleep Physician Dr. James Davis said the clock changes can change our outlook.
“The diminished sleep probably has a negative effect on our moods,” Davis said. “It does me. We are all irritable if we don’t get enough sleep. And the time change in the spring often causes us to lose sleep at night.”
Davis said the time shift also interferes with the body’s internal biological clock, known as the circadian rhythm, which regulates sleep, body temperature, and other bodily functions. Davis said studies have even found small increases in certain health risks in the days following the time change.
“There is a slight increase in heart attacks and fatal car accidents, often involving teenagers,” Davis said. “There is also a decrease in crimes involving physical harm. So, pretty much they offset each other.”
While the effects can be noticeable, Davis said most people will adjust within a few days if they allow their bodies to catch up on sleep.
“Listening to the body helps a lot because your body will tell you if you’re sleep deprived and need to go to bed,” Davis said. “Within days, you should adjust.”
Davis said if you are struggling to go to bed earlier, try limiting electronic devices and bright lights before bedtime.
