Friday Five: The Therapeutic Value of Bonding with Fellow Sports Fans
The Friday Five covers five stories in research that you may have missed this week. There are plenty of controversies and troubling ethical issues in science – and we get into many of them in our online magazine – but this news roundup focuses on new scientific theories and progress to give you a therapeutic dose of inspiration headed into the weekend.
This episode includes an interview with Dr. Helen Keyes, Head of the School of Psychology and Sports Science at Anglia Ruskin University.

Podcast: The Science of Recharging Your Energy with Sara Mednick
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.
