OF EQUIPMENT TO HELP WITH THOSE RECOVERY EFFORTS. DAYLIGHT SAVING TIME AND ON SUNDAY AND OUR CLOCKS WILL FALL BACK. ONE HOUR DAYS WILL BE SHORTER AS TEMPERATURES DROP, WHICH CAN IMPACT OUR MOODS. AND THIS MORNING WE WELCOME DOCTOR GLORIA PETRUZELLI. SHE’S A PSYCHOLOGIST WITH UC DAVIS HEALTH. THANKS SO MUCH FOR JOINING US THIS MORNING. WE APPRECIATE IT. GREAT TO BE WITH YOU. THANK YOU. CAN YOU EXPLAIN ARE THERE SOME SPECIFIC MENTAL HEALTH CONDITIONS THAT ARE MORE AFFECTED BY THIS TIME CHANGE? YEAH. YOU KNOW, THERE’S A SEASONAL AFFECTIVE DISORDER WHICH IS CONSIDERED A DEPRESSIVE DISORDER IS A SUBTYPE OF DEPRESSION. AND SO IF SOMEONE HAS A HISTORY OF DEPRESSION OR MOOD DISORDERS, THAT WOULD PROBABLY MAKE THEM MORE AT RISK FOR BEING AFFECTED BY THIS TIME CHANGE. WHY DO YOU BELIEVE THAT SOME PEOPLE DO HAVE THIS IMPACT TO THEIR THEIR BODIES AND THEIR MENTAL HEALTH BECAUSE OF THIS CHANGE? WELL, FIRSTLY, WE’RE ALL GOING THROUGH THIS CHANGE, RIGHT? WE’RE ALL AFFECTED BY IT AND SOME GET AFFECTED MORE THAN OTHERS. THERE’S SOME GENERAL FACTORS, SUCH AS BEING FEMALE. SO FEMALES ARE DIAGNOSED MORE WITH SEASONAL AFFECTIVE DISORDER THAN MALES. THOSE THAT LIVE IN THE NORTHERN HEMISPHERES ARE AFFECTED, AS WELL AS THOSE THAT HAVE A HISTORY. SO IT’S MULTIPLE FACTORS THAT CAN MAKE SOMEONE AT HIGHER RISK. AND THEN THERE’S LIFESTYLE FACTORS SUCH AS LACK OF OUTDOOR ACTIVITY, POOR SLEEP ROUTINE, IRREGULAR SLEEP PATTERNS, POOR DIET, AND THEN SOCIAL ISOLATION CAN ALSO INCREASE THAT RISK. WHAT ARE SOME SIGNS THAT OUR VIEWERS SHOULD MAYBE LOOK OUT FOR? YOU KNOW, AS WE’RE THINKING ABOUT THIS TIME CHANGE THAT MAY IMPACT US? YEAH, THIS IS A REALLY IMPORTANT ONE SINCE WE KNOW THAT SEASONS ARE PREDICTABLE. WE GO THROUGH THIS TIME SHIFT EVERY YEAR. SO IT’S IMPORTANT TO KNOW YOUR PATTERN. BUT THERE IS A PATTERN THAT IF ALL OF THESE SYMPTOMS WITHIN THE TWO WEEKS, IF THAT ONSET, WE WANT TO MAKE SURE AND GET SOME HELP. SO SPECIFICALLY, IF YOU’RE FEELING SAD, IRRITABLE, DEPRESSED, IF YOU’RE NOTICING SOME APPETITE CHANGES OR YOU’RE NOT EATING AS MUCH, OR YOU’RE EATING TOO MUCH, WHICH CAN LEAD TO WEIGHT GAIN IF YOU’RE ISOLATING, IF YOU’RE NOT WANTING TO ENGAGE WITH LIFE OR WORK OR RELATIONSHIPS, ALL OF THOSE DURING A TWO WEEK PERIOD ARE REALLY IMPORTANT TO KEEP AWARE OF AND TO REACH OUT FOR HELP WITH A LICENSED MENTAL HEALTH PROFESSIONAL. AND WHAT ARE SOME OTHER WAYS FOR PEOPLE TO COPE IF THEY DO START TO NOTICE THESE CHANGES? YEAH, THIS IS A REALLY GREAT QUESTION BECAUSE WE CAN START PREPARING TODAY. WE KNOW THE TIME CHANGE IS GOING TO HAPPEN TOMORROW, BUT FIVE THINGS I WOULD SAY IS TO TRY TO GET DAYLIGHT, TRY TO MAXIMIZE YOUR SUNLIGHT. RIGHT. SO THOSE 10 TO 15 WALKS, EVERY EVERY MINUTE, EVERY MINUTE COUNTS TO GET OUTSIDE. THAT WILL HELP YOU KIND OF ACCLIMATE AND GET YOUR BRAIN KIND OF GEARED UP FOR STARTING THE DAY, EASING INTO THE CHANGE. SO MAKING TINY ADJUSTMENTS THROUGHOUT. SO WHETHER THAT’S, YOU KNOW, KEEPING A CONSISTENT SLEEP ROUTINE. SO GOING TO BED AT THE SAME TIME, WAKING UP AT THE SAME TIME, BEING PROACTIVE IN SCHEDULING SOCIAL ACTIVITIES. SO WHAT WE KNOW IS SOCIAL ISOLATION CAN BE REALLY DETRIMENTAL TO OUR HEALTH. SO PLANNING THOSE ACTIVITIES, COMMITTING TO THEM AND GOING TO THEM, EVEN THOUGH IT MIGHT BE DARK AND YOU WANT TO STAY INSIDE, WE SHOULD KIND OF FOLLOW THROUGH WITH THOSE PLANS AND MAKE IT MAKE IT COZY, NOT ISOLATING. SO ISOLATION IS NOT A COPING SKILL, RIGHT? SO WE WANT TO MAKE SURE WE STAY CONNECTED WITH OUR LOVED ONES AND ALSO GIVE OUR BODIES TIME TO ADJUST TO THE SHIFT. SO IT’S TEMPORARY. I THINK PLANNING AHEAD CAN BE REALLY IMPORTANT. AND MAXIMIZING SUNLIGHT AND KEEPING HEALTHY LIFESTYLE CAN BE REALLY HELPFUL. ALL RIGHT, A LOT OF GREAT ADVICE AND INFORMATION. THANKS SO MUCH FOR JOINING US THIS MOR

Among the clearest impacts is sleep disruption.

Studies show that after the Spring clock change many people sleep less, wake up feeling groggier, and have more fatigue the next day.

If you’re noticing mood dips, extra fatigue, trouble sleeping, or more anxiety around the time change, you’re not imagining it.

It’s real.

Doctors say you should prioritize sleep, seek daylight early, and be aware of mood changes.
