Is Daylight Saving Time to Blame for Seasonal Depression?

The precise root cause of seasonal depression has eluded scientists for years. Now researchers think they’ve found the answer: daylight saving time. They published their report in the journal Epidemiology.

Seasonal depression or seasonal affective disorder (SAD) affects around 1.6 billion people across the globe. Its symptoms mirror those of generalized depression; what differentiates SAD is the timing of its onset, which coincides with winter’s shorter days and long, dark nights.

We know that sunlight, or the absence of it, has a powerful effect on our bodies. But scientists have yet to find a definitive physiological link between darkness and SAD, a fact that makes some wonder if there aren’t other variables at play.

Previous studies have found a relationship between the shift from daylight saving into standard time and other health problems, but they had not looked specifically at the transition’s effect on depression. To get a better idea, an international team of researchers looked at Danish hospital intake records from 1995 to 2012, including 185,419 diagnoses of depression.

As expected, they saw an increase in hospital admissions for depression as winter descended. But that increase spiked at one particular time: the month immediately following the changing of clocks.

The researchers controlled for variables like day length and weather, which they say confirms that the 8 percent rise in depression diagnoses was not a coincidence.

And while their study focused on people with severe depression, the authors say the time shift likely affects “the entire spectrum of severity."

Though the study did not identify the mechanism responsible for time change–related depression, the researchers believe it may have something to do with the way daylight saving manipulates our hours of light and dark. Danish daylight saving protocol steals an hour of daylight from the afternoon and moves it to the early morning—a time, the authors say, when most people are indoors anyway.

"We probably benefit less from the daylight in the morning between seven and eight, because many of us are either in the shower, eating breakfast or sitting in a car or bus on the way to work or school. When we get home and have spare time in the afternoon, it is already dark," co-author Søren D. Østergaard of Aarhus University Hospital said in a statement.

Then there are the psychological effects. In changing the clocks, we are forced to acknowledge the arrival of months of darkness, a realization that Østergaard says “is likely to be associated with a negative psychological effect.”

Fortunately, while we still don’t fully understand the causes of SAD, we have found effective treatments. If you find yourself depressed as the year winds down, talk to your doctor and look into a therapeutic light box.

Veterans Can Now Access Their Health Records Through Apple’s Health App

Apple’s iOS Health app is great for more than just checking how many steps you took during a lengthy walk in the park—it also stores health records from Johns Hopkins, Quest Diagnostics, Allscripts, and more than 400 other healthcare organizations.

Now, Fortune reports that the U.S. Department of Veterans Affairs (VA) has joined that list, making it easier than ever for military veterans who receive healthcare through the Veterans Health Administration to access all of their health records, including medications, immunizations, lab results, and other information. In the press release, Apple explains that the app will automatically update the records, so all veterans need to do is log into their providers’s patient portals through the Health app for a “single, integrated snapshot of their health profile whenever they want, quickly, and privately.”

Though the official announcement coincides nicely with Veterans Day on Monday, the change itself has been in the works for several months—the VA released the new feature to certain patients over the summer.

According to its website, the Veterans Health Administration is the largest integrated healthcare system in the country, servicing more than 9 million patients across 1255 healthcare facilities. With such an expansive network, any successful attempt to streamline processes and improve the flow of information—especially when it comes to sensitive, personal data—has the potential to be a major game-changer for veterans.

“Helping veterans gain a better understanding of their health is our chance to show our gratitude for their service,” Apple COO Jeff Williams said in the press release. “By working with the VA to offer Health Records on iPhone, we hope to help those who served have greater peace of mind that their healthcare is in good hands.”

A Handful of Lucky College Students Live With Senior Citizens in This Minnesota Mansion

When Winona State University student Ashley McGaw skateboards home after a long day of nursing classes, she’s greeted by an unusual entourage: the elderly residents of a Minnesota assisted living facility called Senior Living at Watkins.

According to WFAA, McGaw and several other college kids live there with 45 seniors as part of Winona Health’s “Students in Residence" program, in which students volunteer their time with residents in exchange for discounted rent. For 10 volunteer hours per month, it’s $400, and doubling your hours drops it to just $200 per month. Not only does that include meals, it also gives students the chance to forgo the usual college dorm building for the stately glamour of an old mansion—their rooms are located in the historic Watkins Manor House, which is attached to the assisted living facility.

For freshman Joel Olson, the opportunity seemed like a no-brainer.

“'All you have to do is spend some time with some really nice people?'” he remembers thinking, according to KARE 11. “Of course!”

As for how they spend that time, it’s up to the students. Graduate student Laura Jensen hosts weekly crocheting sessions, nursing student Hanna Rottier offers manicures, and bulletin boards advertise free tech support.

And, in return for sharing their time and talents, students get to experience the familial affection and grandparental concern that’s often scarce on a college campus.

“They all mother me,” Jensen tells KARE 11 about the members of her crocheting club. “They take care of me.”

Winona Health assisted living director Cheryl Krage sees evidence of this, too.

“I hear residents wondering how the students are doing with their studies,” Winona Health assisted living director Cheryl Krage tells KARE 11. “‘Are you eating enough, are you getting enough fruits and vegetable[s]?"

According to the program page on Winona Health’s website, the program is especially beneficial to students looking to enter the healthcare industry, whether that’s medical school, nursing, social work, rehabilitative therapy, or even music therapy.

It also keeps senior citizens connected to the next generation in a deeper way.

“Helps us stay young – ger,” senior resident Diane Sheldon told KARE 11.
