Summary
Recent discussions highlight the alarming health risks associated with prolonged sitting, likening it to the dangers of smoking. Research indicates that sitting for extended periods can significantly increase the risk of premature death, cardiovascular disease, and certain cancers, even among those who meet recommended exercise guidelines. Studies show that for every hour spent sitting, the risk of dying from cardiovascular issues rises by 18%, while the risk of cancer increases by 9%. This phenomenon has led to the term "active couch potatoes," referring to individuals who exercise but still spend excessive time sitting.
Experts emphasize that the body's response to sitting is detrimental, as prolonged inactivity leads to blood pooling in the legs, increased blood pressure, and potential long-term damage to blood vessels. Additionally, sitting can result in higher glucose levels in the blood, which may contribute to insulin resistance and an increased risk of type 2 diabetes and cancer. While standing desks have gained popularity as a solution, research indicates that standing still for long periods can also have negative effects, including stiffer arteries and back pain.
To mitigate the risks of sitting, experts recommend breaking up sedentary time with movement. Simple strategies include standing or walking for a few minutes every half hour, which has been shown to lower blood glucose levels significantly. Incorporating light exercises, such as squats or calf raises, can also be beneficial. Overall, the key takeaway is the importance of regular movement throughout the day to promote better health and reduce the adverse effects of prolonged sitting.
Show Notes
Lots of us spend HOURS a day sitting on our bums. And we’re often told that this is terrible for us — even that it could be as bad for our health as smoking. But how bad is it really? And can exercise or standing desks help make up for all those hours on the couch?? We dig into what happens inside our bodies when we sit all day — with sedentary behavior researchers Prof. David Dunstan and Prof. Bethany Barone Gibbs.

We’re hearing a ton about the marvels of testosterone from influencers, celebrities, and even government officials. They say we should be thinking about our T levels, topping them off with extra if they’re too low. And we’re told that the benefits of testosterone are HUGE: that we’ll be stronger, sexier, and more energized. So is that true?? And if you do go for a testosterone bump, do you need to worry about possible side effects, like ’roid rage, infertility and other risks? We talk to endocrinologists Prof. Shalender Bhasin and Prof. Richard Auchus as well as social psychologist Dr. Justin Carré to find out.
Have you been puzzled by your poos or felt down about your dumps?? You’re not alone! So many of us are struggling with gut issues, which is why fiber is having a major moment. But even though we’re secretly guzzling psyllium husk, tons of us are too embarrassed to talk about our poo problems. No more! We’re putting an end to the silence on stool with Dr. Trisha Pasricha. She’s a neurogastroenterologist and author of “You’ve Been Pooping All Wrong.” We find out what poo actually IS and how often you should go — plus, we get the dirt on the surprising connection between your brain and your gut, and how it might be the key to understanding diseases like Parkinson’s.
Collagen peptides!! Can they make you look younger and be healthier? It feels like everyone wants to be bursting with collagen, and apparently the way to do it is by scooping up that white powder of collagen peptides and guzzling it down. Do that, and — according to the wellfluencers — not only will your skin be as bouncy as a baby's bottom, but you'll also be stronger and you'll heal from injuries faster. But of course, not everyone is on the collagen train. There are the collagen haters, who say that eating collagen is a load of baloney. So who's right? To find out, we talk to dietetics Professor Clare Collins, dermatologist Dr. Natalia Spierings, exercise physiologists Professor Luc van Loon and Professor Keith Baar, neutromuscular physiologist Dr. Robert Erskine, as well as sports performance consultant Dr. Dana Lis.
Our brains go completely WILD when we go through our teenage years. It’s a time where it feels like every disagreement with our parents turns into World War III, and every idea that could get us killed sounds like the most fun we could ever have. In this episode, we get into the science of what the brain is doing during the teenage years with clinical psychologist Dr. Lisa Damour. Lisa co-wrote the college textbook “Abnormal Psychology” and was a consultant on Disney's “Inside Out 2.” She takes us deep into the developing brain to explain what makes teens tick. Plus, we talk about mental health, how boys and girls are struggling in different ways, and tips for anyone who has big feelings.
Stress! We’re all feeling it. And besides just feeling crappy, we’re also told that stress can wreak havoc on our bodies. The internet has a million solutions: vagus nerve stimulators, deep breaths, or a hot sauna! If that doesn’t work, maybe a cold plunge? But what does the science say about all this — what works to lower our stress? And is it really THAT bad to be stressed out? We dive into the research to find out, with psychology Professor Mark Seery, psychology Professor Jeremy Jamieson, and anatomist Dr. Theresa Larkin.
