Dr. Alyssa Kuhn, arthritis specialist physio, walks us through the changes: Take a stand The “sit-to-stand” test, standing from a chair without using your hands (and in various clinical contexts, with parameters such as “how many can be done in one minute?”), is a great indicator of healthy aging and (inversely) mortality risk. Its benefits…

Cori Lefkowith, of “Strong At Every Age” shows us how: It’s time to get a grip Grip strength is associated with longevity, overall strength, and lower mortality risk. That said, it’d be remiss of us to not mention that this is because it’s a proxy for broader physical function rather than something that directly causes…

Obviously at some point you die, but, before that? Dust to dust If we run out of water completely, from every cell in the body, then we will be a desiccated husk and, if not cradled by our surroundings in such a way that we become mummified, then we turn to dust. But, that’s not…

Well, one exercise aside from walking! Can you guess what it is and how it helps? Most people don’t think about this Your calf muscles provide much of your forward propulsion when you walk, but they can weaken rapidly with age, making walking slower and more effortful. But there’s something better than normal calf raises,…

Or at least, whether it’s dubious. Dr. Ruth Machin shares with us a useful tool: TRUST The World Cancer Research Fund developed this simple tool, based on research from University College London, to help people assess health and nutrition claims, identify misinformation, and make better-informed decisions. When considering a health claim, consider the following things:…

Mobility coach Alisa Zuravskaja guides us into greater flexibility, comfort, and stability: It’s in your hips Often, when it feels like your hamstrings are not stretchy enough, what’s actually happening is they’re just compensating for underactive hip flexors, and have got in the habit of “we must remain at least partially tensed at all times…

Dr. Andrea Suarez explains the new research: There are layers to it Hair shedding is a recognized issue in some people taking GLP-1 receptor agonists for weight loss or diabetes. A recent study (mentioned in the video) found a higher rate of newly diagnosed hair loss compared with people taking other diabetes medications, but it’s…

And how safe are they? Take a deep breath… First, understand how asthma affects your lungs: air normally travels through your bronchi into the tiny air sacs (alveoli), where oxygen enters your bloodstream. In asthma, airway muscles tighten, the airway lining becomes inflamed, and excess mucus narrows the airways, making it especially difficult to breathe…

Dr. Amy Konvalin wants us to breathe easy: The ins and outs of it Holding your breath during stress or pain is a normal fight, flight, or freeze response that prepares your body for danger by activating accessory breathing muscles in your neck and chest instead of your diaphragm, often leading to the “freeze” response…

What’s the worst that can happen? The news is not eggs-cellent Let’s crack into it: Salmonella is a bacterium that infects millions of people each year, causing fever, stomach cramps, and diarrhea, and is the leading cause of hospitalizations and deaths from food poisoning. Chickens often carry it without symptoms, allowing it to spread into…

Will Harlow, the over-50s specialist physio, shows us how to stay out of hospital: Making sure it all works how it’s supposed to First, understand that most knee pain is mechanical: more than 80% of knee pain cases* not primarily caused by injury or arthritis, but by abnormal forces from stiffness, tightness, or weakness affecting…

And how can we make use of this? Upon the genes… Much like an epidemic is upon the people (epi+demos), epigentics is “upon the genes”. Or more specifically, the study of how DNA interacts with molecules that switch genes on or off without changing the DNA sequence itself. The thing to understand here is that…
