    The Science of Healthy Hair: What Actually Matters

    Hair health is more complicated than buying a “hair, skin & nails” supplement. In this episode, we’re unpacking what may actually matter when it comes to nutrition and healthy hair, including: Ferritin vs. iron: why your iron stores can matter even before obvious anemia developsWhy there isn't one universally accepted “perfect” ferritin level for hair growthHepcidin: what it is and why taking iron more often doesn't necessarily mean absorbing more ironWhy alternate-day iron dosing has become an interesting strategy in the researchWhy the form of an iron supplement matters, including ferrous bisglycinateFood and supplement combinations that can help, or interfere with, iron absorptionWhy adequate protein matters for hairWhere collagen fits, and why collagen shouldn't replace complete dietary proteinWhy “more biotin” isn't automatically the solutionThe difference between hair shedding and hair breakageHow heat and everyday hair-care practices can damage the hair shaftThe bigger takeaway: Hair is often treated like a cosmetic issue, but nutrition, nutrient status, and what’s happening inside the body can play an important role. Instead of blindly adding another supplement, start by asking why the changes may be happening. Wellness Explained Evidence-based wellness, explained simply. Hosted by Sandy Jolles, MS, CNS, LDN.

    What Actually Matters in Skincare? Separating Science From Marketing

    Skincare has become increasingly complicated. We're told to layer serums, rotate actives, protect our skin barrier, use retinoids, add vitamin C, avoid certain ingredients, and somehow figure out whether the $200 product is actually better than the $20 one. But does good skincare really need to be that complicated? In this episode, Sandy sits down with Shelly Hokanson, certified cosmetic formulator and founder of Geek Out of Water, to talk about what actually matters when choosing skincare, and how to become a smarter consumer without needing a degree in cosmetic chemistry. Shelly's background in media literacy has shaped the way she approaches skincare: Who made this product? What's actually in it? What does the company want us to believe about it? And most importantly, what evidence supports the claim? In This EpisodeWhat “clean,” “natural,” “non-toxic,” and “hypoallergenic” actually mean, and why these terms aren't necessarily as standardized as consumers may assume Pasted textWhat to know about claims like “dermatologist tested,” “clinically tested,” and “detoxifying” Pasted textWhy expensive skincare isn't automatically betterHow too many actives and too much exfoliation can backfireSigns your skin barrier may be strugglingThe simple foundation of an effective skincare routineRetinoids, vitamin C, eye creams, and sunscreenHow to read an ingredient list without becoming a cosmetic scientistWhat Shelly calls “pixie dusting”- when a heavily marketed ingredient may appear in only a very small amount Pasted textSAVE or SPLURGE: where Shelly thinks your skincare dollars are, and aren't, worth spendingShelly Hokanson is a certified cosmetic formulator, professor in the School of Media Arts & Design at James Madison University, and founder of Geek Out of Water (GOOW). With nearly three decades in the classroom and a decade creating content on YouTube, Shelly brings her background in media literacy to the world of skincare, helping consumers better understand ingredients, formulation, cosmetic science, and the marketing behind the products they buy. Her work focuses on making skincare education approachable and empowering people to become more informed consumers. A Few Terms Mentioned in the EpisodeVitamin C forms:L-Ascorbic AcidTHDA: Tetrahexyldecyl AscorbateMAP: Magnesium Ascorbyl Phosphate Phenoxyethanol: Shelly discusses using this common preservative as a helpful reference point when looking at where highlighted ingredients appear on an ingredient list. She also notes an important caveat: some effective ingredients are intentionally used at concentrations below 1%, so placement alone doesn't tell the whole story.

    Do Vibration Plates Actually Work? What the Research Says

    Vibration plates have become one of the biggest wellness trends, but there's a difference between a tool having potential benefits and being a replacement for exercise. In this episode, Sandy takes a closer look at whole-body vibration and what the research actually tells us. You'll learn: • What whole-body vibration actually does to the body• How vibration may stimulate involuntary muscle contractions• What the research suggests about muscle activation and strength• Potential benefits for balance and stability• What we know about vibration training and bone health• Why vibration plates are often marketed for circulation and recovery• Whether simply standing on a vibration plate is enough• Why vibration plates shouldn't replace strength training, walking, or other forms of movement• How to think about vibration plates as a supplement to, not a substitute for, your exercise routine• Whether a vibration plate may actually deserve a place in your wellness routine The bottom line? You don't need a vibration plate to be healthy...but it may be a useful tool when it's used for the right reasons. Wellness Explained Evidence-based wellness, explained simply.

    Wellness Bite: Do You Actually Need Electrolytes?

    Electrolyte powders, packets, and drinks have become a wellness staple, but does everyone really need them? In this Wellness Bite, nutritionist Sandy Jolles breaks down what electrolytes actually do, when replacing them may be helpful, and why your individual needs matter. In this episode: What electrolytes are and why your body needs themWhy sweating and exercise aren't the only factors that can affect fluid and electrolyte balanceHow heat, illness, and other fluid losses can increase electrolyte needsWhy lower-carbohydrate diets can increase sodium and water lossesThe nuance around caffeine, coffee, and hydrationHow certain water-filtration methods can reduce naturally occurring mineralsWhy the word “electrolytes” on a package doesn't tell you whether a product is right for youWhat to consider when comparing electrolyte products, including sodium contentWhy more electrolytes isn't automatically betterThe takeaway: Electrolytes can be incredibly useful in the right circumstances, but you don't necessarily need to add them to every glass of water. The goal is to understand why you're using them and choose a product that actually matches your needs. Wellness Explained Evidence-based wellness, explained simply.

    Should You Work Out Fasted? What to Eat Before & After Exercise

    Should you eat before a workout? Is exercising fasted better for fat loss? And how quickly do you really need to get protein after you finish? In this episode, Sandy takes a closer look at workout nutrition and separates what actually matters from some of the noise surrounding pre- and post-workout fueling. In this episode: • What actually happens when you exercise fasted• Fasted training vs. fasted fat loss, and why they aren't necessarily the same thing• When eating before exercise may improve performance• How workout length and intensity change your fueling needs• What to eat before a workout• Why carbohydrates aren't something to fear around exercise• Protein, muscle protein synthesis, and muscle growth• What to eat after a workout• Whether the post-workout “anabolic window” is really as narrow as we've been told• Where foods like Greek yogurt and dairy can fit, and what to do if they don't agree with you• Why your overall daily protein and nutrition matter more than perfectly timing one meal• A simple takeaway you can start using with your next workout The bottom line: You don't need to micromanage every bite around your workouts. Fueling should support the type of exercise you're doing, your goals, your performance, and how you actually feel. Wellness Explained Evidence-based wellness, explained simply.

    Wellness Bite: Red Light Therapy - Worth the Hype?

    Red light therapy has gone from a niche wellness treatment to something you can find in gyms, spas, recovery studios, and even at home. But what is it actually doing, and is it worth your time and money? In this Wellness Bite, Sandy takes a quick look at the science of red and near-infrared light therapy, also known as photobiomodulation. She explains how specific wavelengths of light interact with our cells, why mitochondria are often part of the conversation, and where the research is most promising. You'll also learn why not every red light device is created equal and why factors like wavelength, dose, distance, and consistency matter when evaluating whether a device may actually be effective. Rather than treating red light therapy as either a miracle treatment or another wellness gimmick, this episode helps you understand where the evidence currently stands so you can make a more informed decision. In this Wellness Bite: What red and near-infrared light therapy actually areHow photobiomodulation may affect cellular functionPotential applications for skin health and exercise recoveryWhy wavelength and dosing matterWhat to look for when considering an at-home deviceWhere the evidence is promising, and where we still need more research Wellness Explained Evidence-based wellness, explained simply.

    Why You're Tired Even When You're Getting Enough Sleep

    Getting enough sleep doesn't always mean getting restorative sleep. You can spend seven or eight hours in bed and still wake up exhausted...and sometimes, the reason has less to do with how long you're sleeping and more to do with what's happening during those hours. In this episode of Wellness Explained, Sandy explores some of the less obvious reasons you may still feel tired despite getting what seems like enough sleep. You'll learn about: Why sleep duration and restorative sleep aren't necessarily the same thingHow stress, cortisol, and the HPA axis interact with sleepWhy “adrenal fatigue” isn't the same thing as true adrenal insufficiencyWhen persistent fatigue may warrant looking beyond sleep and discussing bloodwork with your healthcare providerThe roles of iron, ferritin, vitamin B12, thyroid function, and other potential contributors to fatigueWhy alcohol can help you fall asleep faster while still disrupting the sleep that followsHow light exposure and red-light therapy fit into the sleep conversationHow sleep apnea can repeatedly disrupt sleep without you remembering waking upWhy snoring, mouth breathing, and waking with a dry mouth may be worth paying attention toWhy simply mouth taping isn't a solution for unexplained nighttime mouth breathingOne simple way to give your circadian rhythm a more consistent signalThe big takeaway: Being in bed long enough doesn't necessarily mean your body and brain are getting the restorative sleep they need. Sometimes the answer isn't another cup of coffee, another supplement, or another sleep hack. Sometimes it's getting curious about why you're tired in the first place.

    Wellness Bite: Does Eating Late at Night Actually Cause Weight Gain?

    You've probably heard the rule: “Don't eat after 8 PM.” But does your metabolism really have a bedtime? In the very first Wellness Bite, Sandy takes on one of the most common nutrition rules and looks at what the research actually says about eating later in the day. It turns out there's no magical hour when food suddenly becomes more likely to turn into body fat...but that doesn't mean meal timing is completely irrelevant. In this episode, you'll learn: Why eating after 8 PM doesn't automatically cause weight gainHow your circadian rhythm may influence appetite and metabolismWhy the same meal may produce a different glucose response depending on when you eat itWhat controlled studies have found about eating more calories earlier vs. laterWhy late-night eating may sometimes have more to do with under-eating during the day than a lack of willpowerWhether shifting more of your daily intake earlier may be worth consideringThe bottom line? There isn't a universal time when you need to stop eating. Meal timing may matter, but something can matter without being the thing that matters most. Instead of obsessing over the clock, it may be more useful to ask: “What does my overall eating pattern look like?” Wellness Explained Evidence-based wellness, explained simply.

    Are We Overcomplicating Wellness?

    Has being healthy somehow become a full-time job? Between supplements, wearables, 10,000-step goals, sleep optimization, red light therapy, and the latest longevity hacks, it's easy to lose sight of what actually matters most. In the very first episode of Wellness Explained, nutritionist Sandy Jolles explores the science behind the health habits that truly move the needle...and the ones that might just be icing on the cake. In this episode, we explore: • Why muscle is about much more than strength or aesthetics• The surprising relationship between cardiorespiratory fitness and longevity• Why 10,000 steps isn't a magic biological threshold• What happens when you walk after a meal• Why fiber is much more interesting than its reputation• How sleep affects metabolic health• The surprisingly powerful connection between relationships and health• Why more health data doesn't always create better health• Where creatine, cold plunges, red light therapy, greens powders, and apple cider vinegar might fit And we'll come back to a question that will be central to Wellness Explained: Not just “Does it work?...but how much does it actually matter? Because wellness should be fun. We're just going to make sure the science comes with us. Wellness Explained Evidence-based wellness, explained simply. Hosted by Sandy Jolles, MS, CNS, LDN.
