In the first class of our course on making the most of your friendships, host Cristina Quinn learns what it means to be socially fit — and why it’s never too late to start getting those reps in. Cristina talks to Bob Waldinger, director of the Harvard Study of Adult Development — the longest longitudinal study on human happiness — about why friendships matter for our health and what we can do to assess our connections. He gives practical advice for how to take stock of, reinvest in or rethink our relationships, with exercises that can work as an ongoing social fitness regimen.

You can learn more about the Harvard Study of Adult Development here. Waldinger and his colleague wrote a book, “The Good Life,” that includes more tips for finding satisfaction in human relationships.

In the fifth and final class of our course on how to get better sleep, we focus on melatonin. Researchers found that melatonin use in the United States more than quintupled between 1999 and 2018. You might know someone who swears by melatonin or maybe you yourself do. But does it work? What do we know about how effective melatonin supplements are, and what does it mean for helping you get better sleep? Cristina unpacks the research and helps you determine if melatonin is the right choice for your sleep needs. 

Here are some organizations and labels to look for when purchasing melatonin supplements:

• National Sanitation Foundation
• United States Pharmacopeia

In class 4 of our course on how to get better sleep, Cristina and sleep expert Lisa Strauss explore the concept of sleep drive. Counterintuitively, sometimes you need to increase your need for sleep, even if you’re exhausted already. Lisa Strauss explains a technique called sleep compression, where you limit your sleep opportunity to a more sustainable quantity – and you just might find the sweet spot for the amount that best suits your body over the long-term. What does this have to do with pizza? You’ll find out – and it will be delicious.

In class 3 of our course about how to get better sleep, we dig in on a moment most of us are familiar with – waking up in the middle of the night and not being able to fall back asleep. Sometimes our default setting is to keep thinking our endless thoughts, but, it turns out, what we really need is a distraction. And you want to make sure to find the right kind of distraction – one that requires little to no thinking or mental commitment. Cristina explores tips on how to do that and an accessory that can help.  

Here are some of Cristina’s favorite suggestions for soothing distractions that might work for you:

• The autobiography of Eleanor Roosevelt
• Rick Steves’s travel podcasts
