17-32 Segment 2: Social Jetlag


New research indicates that shifting your sleep schedule by as little as one hour can lead to fatigue, increased grumpiness and sleepiness, which is referred by scientists as “social jetlag.” Sierra Forbush, a researcher at the University of Arizona-Tucson, says that social jetlag is comparable to jet lag, but instead of feeling tired because of the change in time zones, people feel tired because of the change in their social responsibilities. Further, it turns out that everyone experiences the same amount of social jetlag, regardless of age or gender.

Did you know that 86% of people say that they shift their sleeping schedule on the weekend? Even with so many people changing their sleeping schedule weekly, we don’t really know much about why it affects our health in the way that it does. What we do know is that when we wake up earlier or later than what we’re accustomed to, we can trigger a hormonal change that leads to fatigue and irritation. So, even if you sleep longer on the weekends, what affects your health and mood is not the amount of sleep you get, but the disruption in the natural cycle of sleep that your body is used to.

The Risks of Egg Donation

Some agencies estimate that 50,000 children have been born in the US using donor eggs. But egg donation (or sale, as some insist) is not regulated, and while short term risks are known, few donors have been followed for years. Long term risks are not well understood. Experts discuss what we know… and what we don’t.

Social Jetlag

New studies show that changing your weekday sleep schedule by sleeping in as a little as an hour every weekend can have severe health impact. Experts discuss this “social jetlag,” why it occurs, and how people can avoid health concerns without avoiding staying out late.
