WILL TRAP THE MOISTURE ALREADY
ON YOUR SKIN.
IF YOU HAVE A QUESTION, GO TO
WCCO.COM/LINKS.
IF YOU ARE THE PARENT OF A
CHILD WITH A CELLPHONE, YOU HAVE
PROBABLY BEEN IN A BATTLE TRYING
TO TAKE THAT PHONE AWAY AT
BEDTIME.
BUT DOES THAT SCREEN TIME
REALLY MAKE A DIFFERENCE?
THE SLEEP CENTER WCCO TRACKED
THE PHONE USAGE OF THREE
TEENAGERS.
AS LIZ COLIN DISCOVERED DOCTORS
WERE SURPRISED AT WHAT DID AND
DIDN'T HAPPEN.
OUR TEST INVOLVES THREE
JUNIORS IN HIGH SCHOOL, ALL 16,
WHO USE PHONES AND SOCIAL MEDIA.
CLAIRA USES HERS RIGHT BEFORE
BED.
SHE ADMITS SHE IS TIRED BUT
STAYS AWAKE TO SNAPCHAT AND TEST
SOMETIMES FOR A COUPLE HOURS.
MATT DAVIS KEEPS HIS PHONE
DOWNSTAIRS, BUT HIS PARENTS
WORRIES HE DOES HOMEWORK TOO
LATE.
HE SETS TWO ALARMS TO BE ABLE TO
GET UP BY 6:30.
AND THE LAST TEENAGER IS PATRICE
SHELTON.
SHE DOESN'T SPEND TIME AT ALL
BEFORE BED.
HER PARENTS LIMIT IT TO 30
MINUTES A DAY.
SHE DOESN'T HAVE TO GET UP 7:45,
ALARM.
AT THE SLEEP DISORDER CENTER AT
HENNEPIN MEDICAL CENTER GIVES
THEM WHAT IS CALLED AN ACT
GRAPH.
IT WILL DETECT YOUR MOTION
WHEN YOU ARE ASLEEP AND WHEN
AWAKE.
EACH STUDENT IS ALSO ASKED
TO KEEP A HANDWRITTEN LOG FOR
TWO WEEKS.
I WANT YOU TO TELL ME WHEN
YOU GO TO BED AND WHEN YOU GET
UP IN THE MORNING.
HE HAS STUDIED HOW OUR CIRCA
CIRCADIAM RIT MS SHIFT.
NO MATTER.
THEY SAY NINE HOURS OF SLEEP FOR
TEENS IS BEST.
NOW THE DAY IS ACCUMULATING
AND WE KNOW HOW IMPORTANT SLEEP
IS TO A DEVELOPING BRAIN.
GOOD LUCK GETTING THE BRAIN
TO TURN OFF.
INVENTION OF THE LIGHT BULB HAS
MADE IT WORSE, ALL THE LIGHT
THESE SCREENS SUBMIT SUPPORTS
MELANIN, IT HELPS GET TO SLEEP
AND STAY THERE.
IPHONES HAVE A WAY FOR YOU
TO TONE THAT LIGHT DOWN.
IT'S A FEATURE CALLED NIGHT
SHIFT THAT ALLOWS USERS TO GIVE
OFF LESS BLUE LIGHT BEFORE BED.
THE DOCTORS WAS INTERESTED TO
SEE IF IT MADE A DIFFERENCE,
REMEMBER SHE IS THE ONE THAT
USES THE PHONE THE MOST.
SHOULD AFFECT THE QUALITY OF
SLEEP.
SO YOU ARE INTERESTED IN HOW
THIS TURNS OUT.
ABSOLUTELY.
YOU ARE GETTING 81/2 HOURS
OF SLEEP.
TWO WEEKS LATER PATRICE AND
MATT, HE HAD A MALFUNCTION, BUT
HIS SLEEP LOG STILL SHOWED HE
WAS GETTING ENOUGH SLEEP.
BUT WHEN YOU GET THE QUALITY,
THERE IS A DIFFERENCE.
VERY LITTLE MUSCLE ACTIVITY.
IN ADDITION TO CONSISTENT
BED AND WAKEUP TIMES, THE DOCTOR
SAYS THE TEENAGER WHO USES HER
PHONE THE LEAST EXPERIENCES
RESTFUL SLEEP, WHILE CLAIRA'S
PRINTOUT REPRESENTS MORE
MOVEMENT, DOCTOR BELIEFS HER
BRAIN MAY NOT BE AS RELAXED
GOING TO BED AND WHEN CLAIRA
FLIPPED ON THE NIGHT SHIFT THERE
WAS NO DIFFERENCE IN HER
RESULTS.
MAYBE IT'S NOT A LIGHT
ISSUE, BUT A BRAIN ISSUE.
HE SAYS IT MAY HAVE LESS TO
DO WITH SCREENS AND LIGHTS BUT
MORE TO DO WITH QUIETING OUR
MINDS BY DISENGAGING WITH OUR
DEVICES, MAYBE IT MIGHT BE TIME
TO GRAB THOSE PHONES FROM OUR
KIDS WAY BEFORE WE SAY GOOD
NIGHT.
IT MAY BE HARD, BUT I THINK
IT'S IN THEIR BEST INTEREST
AND SHEER IS WHAT THEY SAY
IS -- HERE IS WHAT THEY SAY IS
