45 minute rule

Consider this the counterpoint to yesterday's newsletter. Also... actually, we have to skip the 7 other things section for a couple of days. It'll be back soon!

I think today’s newsletter is sort of the counterpoint to yesterday’s.

Anxiety and depression are on the rise during the coronavirus. This article is about a new scientific study that suggests something most people can do about it.

First, the scope of the problem. A study by Mental Health America says anxiety and depression screenings are up 370 percent and 394 percent over where they were just a month before the pandemic.

And as I wrote recently, the U.S. Census Bureau reports that a full third of Americans now show signs of clinical depression or anxiety--numbers that top psychiatrists at Massachusetts General Hospital in Boston say are “becoming amplified during the recent pandemic.”

But this other new study suggests there's a simple thing that most people can do each day to overcome the negative feelings of anxiety and depression that many Americans currently feel.

Writing in the International Journal of Environmental Research and Public Health, Chinese researchers said they conducted a longitudinal study of 66 college students during the peak time of the Covid-19 outbreak in China.

Their goal was to collect and correlate information on each participant's demographics, level of physical activity, level of negative emotions, sleep quality, and aggressiveness level.

The results? Negative emotions were appreciably less prevalent when study participants engaged in “45 minutes of vigorous physical activity every day.”

Similar effects could be found with 108 minutes of light physical activity or 80 minutes of moderate activity--although when we start talking about nearly two hours of activity, I get that it can be a little less easy to fit into people's schedules.

So, the 45-minute rule it is.

None of the students in the study was diagnosed with Covid-19, and so it's worth noting two things:

  • First, it appears that their increased anxiety and negative emotions were caused as much by social distancing and other practical reactions to the virus as by fear of the virus itself.

  • Second, the amount of vigorous physical activity suggested by this study's results is noticeably higher than in pre-pandemic studies.

“This is probably because of the special period of the Covid-19 outbreak,” the study authors wrote. “People need additional [physical activity] to offset the psychological burden and negative emotions caused by the disease outbreak and social distancing.”

That last point is insightful. For while we all know that physical exercise is linked to better emotions in general, the truth is that study after study says something else is more important, if you had to pick only one thing: social relationships.

But during this time of social isolation, the medical necessity of physical distancing from other people makes it harder to maintain those kinds of relationships.

In fact, a top psychologist who studies the science of happiness recently recommended that we stop using the phrase "social distancing" and instead replace it with "physical distancing and social solidarity​."

That came as part of yet another study showing that exercise--along with self-care like participating in hobbies, engaging in spiritual activities, and helping other people--increased positive mental health.

So, work on relationships--and exercise vigorously for 45 minutes each day.

If you're not doing it yet, the science says it will help your mental health--and make it easier to get through this unprecedented time.

7 other things worth your time

  • Aw, man. Scientists say they’ve identified the first case of Covid-19 reinfection in the U.S., casting further doubts on the idea of a natural herd immunity. The man’s second infection was much worse than the first one, apparently. (Forbes)

  • A 7-year-old with autism, weighing 80 pounds, was handcuffed and pinned to the ground by a school resource officer in North Carolina. The cop, who has since resigned, “taunted him” for 40 minutes. The boy’s family is now suing. (The Washington Post)

  • Just 1 drop off ballot box per county in Texas, according to a federal appeals court, which upheld the governor’s order restricting them. (NBC News)

  • Researchers tackled a giant question: Do cats actually know their names? (Spoiler: not really, but they may associate the sound of their names with rewards.) (Science Magazine)

  • Killer whales are supposedly teaming up to attack boats off the northern coast of Spain, and some researchers think it’s because they’re taking revenge “due to injuries several of them sustained over the summer from rudders.” (NY Post)

  • This is pretty inspiring: A nurse practictioner at a Massachusetts hospital shared a photo of her work IDs over the years — showing how she started at the hospital as a janitor, and purused her education while rising through the ranks to achieve her dream. (MassLive)

  • I don’t think I’ve ever recommended a TV show here before, but since my wife and I watched the whole thing recently and I looked forward to each episode, I give you: “Ted Lasso,” on Apple TV, described as “a big-hearted puppy dog of a series, an anti-cringe comedy where everything that seems like it might go wrong goes right instead. It’s counterprogramming for the state of the world.” If you’ve ever felt underestimated, but also kind of understood that the true joke was on whomever was doing the underestimating, I think you’ll like it.
