We're joined by a trio of giants when it comes to the state of wearable sleep trackers and the data they offer. How accurate is it? What number should we be watching? And how much of this information do we actually need?

After she had her baby, Dr. Jade Wu from Duke University School of Medicine basically went through every sleep issue in the known universe. We talk about how the script gets flipped when the doctor becomes the patient.

Dr. Michael Grandner from the University of Arizona returns to the show with a look at one of the problems facing the scientific community.

Everything from sleep to Covid to REM sleep vs Deep sleep, the 'truthiness' of science claims - all of it is on our exam table.

One is an actual rock star - Lawrence Gowan from Styx talks about health, fitness and sleeping on the tour bus for rock stars who are, like fine wine, getting better with age. (He also weighs in on Styx not being members yet of the Rock & Roll Hall of Fame.)

The other is a rock star in the sleep world - Dr. Mark Boulos from Sunnybrook Health Sciences Centre in Toronto is Neil's sleep specialist, and offers important information that could completely change the life of someone you care about if sleep issues come along with mental health concerns as well.

Screw your opinion, what does the science say?

The Snooze Button is back after an eighteen-month hiatus with an all-star panel of experts to tackle this (t)horny question: Does sex improve your sleep?

Hey, Bedheads! We're back!

Sleep trackers and tracking technology are among the many obsessive interests of one Jesse Cook, PhD student and perhaps Twitter's most prolific sleep nerd. He's written a ton of papers about trackers and sleep tech. He geeks out with Neil this week on wearables, "nearables" and where the gear is heading.

The two also cover Restless Legs Syndrome, and how trackers can serve as beacons for RLS.
