Why You STILL Feel Tired After Sleeping In | Inverse


– You can’t catch up on sleep. The long held belief that over the weekend you can make up for all of the lost sleep you didn’t get over the week,
turns out that’s a myth. In a study conducted by The
University of Colorado Boulder it was shown that al of
the health risks associated with sleep deprivation
such as weight gain, increased blood pressure, higher risk for heart attack and stroke, all of these things did not go away after a healthy amount of
bonus sleep over the weekend. Okay, let’s break down the study. So, the participants were
split into three groups. There was the control group
and two experimental groups. In the control group,
all those participants got a healthy nine hours of
sleep each night for one week. That’s the group that I
would like to be a part of. And there were two experimental groups, each of which only got five
hours of sleep a night. One of these experimental
groups, WR, was given the chance to recover with ad libitum
sleep over the weekend. This averaged out to about
1.1 bonus hours of sleep compared to the baseline,
which is at about nine hours of sleep. The other experimental group, SR, did not get a chance to recover. I do not want to be a part of that group. Then, the WR group went
back to only five hours of sleep a night to measure how effective this bonus sleep was at preventing any of these health risks. Here’s what they found. During insufficient sleep,
both the SR and WR groups experienced weight gain
or after dinner eating, insulin insensitivity and
disrupted circadian rhythm. The WR group did momentarily
recover in some areas, such as weight gain and
after dinner energy intake, but as soon as they went
back to insufficient sleep, both of these factors became issues again, and it was like they had never gotten the bonus sleep at all. In both the WR and SR
groups, insulin sensitivity decreased significantly. 13% in the fully sleep restricted SR group and nine to 27% in the WR group. And this is a huge health risk, cause insulin insensitivity
can lead to diabetes. So in conclusion, while this study shows that you might feel better
on Sunday afternoon, ultimately, a week’s worth
of insufficient sleep can do a lot of damage to your body, and all of the metabolic
derangement that comes from one weekend of getting restful
sleep, is not gonna cut it. Your circadian rhythm
still gonna be out of wack. Your blood pressure
still gonna be increased. And it was even shown that
participants ate an additional 500 calories after dinner. That’s a big difference. Just remember, sleep
is not for the weekend. It’s for tonight. So to keep up to date with
all of your science questions and concerns, subscribe to inverse. We’re gonna be giving you
guys all the information you’re ever gonna need. I’m Justin, I’ll catch you guys next.
