Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken tackle the confusion around every aspect of our health and wellbeing.

In this episode, they’re asking, what’s the deal with naps? Some people nod off in minutes, while others can’t manage it at all. So why is napping so different from person to person? Is it actually good for us? Is there a “right” way to nap - and should we all be making time for it? Also, they uncover what’s really happening inside the brain when we drift off.

To help answer these questions, they’re joined once again by Russell Foster, Professor of Circadian Neuroscience at the University of Oxford. If you want to get in touch, you can email us at whatsupdocs@bbc.co.uk or WhatsApp us on 08000 665 123.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
