Podcast: The Science of Recharging Your Energy with Sara Mednick

For today's podcast episode, Leaps.org talks with Sara Mednick, author of The Power of the Downstate, a book about the science of relaxation - why it's so important, the best ways to get more of it, and the time of day when our bodies are biologically suited to enjoy it the most.

If you’re like me, you may have a case of email apnea, where you stop taking restful breaths when you open a work email. Or maybe you’re in the habit of shining blue light into your eyes long after sunset through your phone. Many of us are doing all kinds of things throughout the day that put us in a constant state of fight or flight arousal, with long-term impacts on health, productivity and happiness.

My guest for today’s episode is Sara Mednick, author of The Power of the Downstate, a book about the science of relaxation – why it’s so important, the best ways to go about getting more of it, and the time of day when our bodies are biologically suited to enjoy it the most. As a cognitive neuroscientist at the University of California, Irvine, Mednick has a great scientific background on this topic. After getting her PhD at Harvard, she filled her sleep lab with 7 bedrooms, and this is where she is federally funded to study people sleeping around the clock, with her research published in top journals such as Nature Neuroscience. She received the Office Naval Research Young Investigator Award in 2015, and her previous book, Take a Nap! Change Your Life was based on her groundbreaking research on the benefits of napping.

In our conversation, we talk about how work and society make it tough to get stimulation like food and exercise in ways that support our circadian rhythms, and there just as many obstacles to getting sleep and restoration like our ancestors enjoyed for 99 percent of human history. Sara shares some fascinating ways to get around these challenges, as well as her insights about the importance of exposure to daylight and nature vs nurture when it comes to whether you’re a night owl or an early bird. And we talk about how things could change with work and lifestyles to make it easier to live in accordance with our biological rhythms.

Time to visit your TikTok doc? The good and bad of doctors on social media

Rakhi Patel is among an increasing number of health care professionals, including doctors and nurses, who maintain an active persona on Instagram, TikTok and other social media sites.

Rakhi Patel has carved a hobby out of reviewing pizza — her favorite food — on Instagram. In a nod to her preferred topping, she calls herself thepepperoniqueen. Photos and videos show her savoring slices from scores of pizzerias. In some of them, she’s wearing scrubs — her attire as an inpatient neurology physician associate at Tufts Medical Center in Boston.

“Depending on how you dress your pizza, it can be more nutritious,” said Patel, who suggests a thin crust, sugarless tomato sauce and vegetables galore as healthier alternatives. “There are no boundaries for a health care professional to enjoy pizza.”

Beyond that, “pizza fuels my mental health and makes me happy, especially when loaded with pepperoni,” she said. “If I’m going to be a pizza connoisseur, then I also need to take care of my physical health by ensuring that I get at least three days of exercise per week and eat nutritiously when I’m not eating pizza.”

She’s among an increasing number of health care professionals, including doctors and nurses, who maintain an active persona on social media, according to bioethics researchers. They share their hobbies and interests with people inside and outside the world of medicine, helping patients and the public become acquainted with the humans behind the scrubs or white coats. Other health care experts limit their posts to medical topics, while some opt for a combination of personal and professional commentaries. Depending on the posts, ethical issues may come into play.

Could this habit related to eating slow down rates of aging?

Previous research showed that restricting calories results in longer lives for mice, worms and flies. A new study by Columbia University researchers applied those findings to people. But what does this paper actually show?

Last Thursday, scientists at Columbia University published a new study finding that cutting down on calories could lead to longer, healthier lives. In the phase 2 trial, 220 healthy people without obesity dropped their calories significantly and, at least according to one test, their rate of biological aging slowed by 2 to 3 percent in over a couple of years. Small though that may seem, the researchers estimate that it would translate into a decline of about 10 percent in the risk of death as people get older. That's basically the same as quitting smoking.

Previous research has shown that restricting calories results in longer lives for mice, worms and flies. This research is unique because it applies those findings to people. It was published in Nature Aging.

But what did the researchers actually show? Why did two other tests indicate that the biological age of the research participants didn't budge? Does the new paper point to anything people should be doing for more years of healthy living? Spoiler alert: Maybe, but don't try anything before talking with a medical expert about it. I had the chance to chat with someone with inside knowledge of the research -- Dr. Evan Hadley, director of the National Institute of Aging's Division of Geriatrics and Clinical Gerontology, which funded the study. Dr. Hadley describes how the research participants went about reducing their calories, as well as the risks and benefits involved. He also explains the "aging clock" used to measure the benefits.
