Energized with Dr. Mariza

Have you ever gotten to the end of a long day on your computer and felt like your brain was simply done? Your eyes are tired. You can’t focus. Light feels irritating. Reading takes more effort. Maybe you even start avoiding your phone because you cannot look at another screen. Most of us assume that means our eyesight is getting worse. But in this episode, Dr. Mariza sits down with neuro-optometrist Dr. Bryce Applebaum to explain why eyesight and vision are not the same thing. Eyesight describes how clearly you see. Vision involves how your brain receives, filters, processes, coordinates, and responds to the information coming through your eyes. And when that eye-brain connection isn’t functioning efficiently, symptoms can show up as headaches, motion sickness, dizziness, trouble focusing, sensory overload, brain fatigue, and even ADHD-like behaviors. Dr. Bryce also explains why screens place such unusual demands on the visual system, why functional vision issues can become more noticeable during midlife, and how concussion and other brain injuries can disrupt vision even when standard eye exams look normal. The encouraging part? The brain remains adaptable. Through targeted vision training and the right evaluation, Dr. Bryce explains that the eye-brain connection can often be retrained and strengthened at almost any age. DR. BRYCE APPLEBAUM Dr. Bryce Applebaum is a neuro-optometrist specializing in vision performance and helping people improve how their eyes, brain, and body work together. His work focuses on functional vision, visual processing, traumatic brain injury, concussion recovery, learning challenges, screen-related visual stress, and vision performance training. In this conversation, Dr. Bryce explains why a traditional eye exam may miss important functional vision problems and why improving vision can involve far more than simply changing a glasses or contact lens prescription. IN THIS EPISODE Why eyesight and vision are two very different things How functional vision problems can cause brain fog, headaches, motion sickness, and sensory overload Why visual processing problems can sometimes look like ADHD How changing hormones and screen exposure can increase visual strain in midlife Why screen time places unusual demands on the eye-brain connection The childhood signs that may point to an undiagnosed functional vision problem Why concussion and traumatic brain injury can affect vision even when eyesight appears normal How vision performance training uses neuroplasticity to retrain the brain Practical ways to reduce screen strain and support healthier visual development QUOTES “Any brain at any age has the opportunity to be trained and rewired.” “There’s neuroplasticity for vision at every age.” “If we’re testing, we’re not guessing.” RESOURCES MENTIONED Stop surviving and start thriving, join Midlife on Fire Collective now https://drmariza.com/trial Dr. Bryce Applebaum Website https://myvisionfirst.com/ ScreenFit online vision training program https://www.screenfit.com/ Dr. Bryce Applebaum Instagram RELATED EPISODES  744: The Midlife Brain Reset: How to Protect Your Memory, Focus, and Mental Sharpness Starting Now 668: Your Brain on Perimenopause: The Hidden Neurological Transition No One Warns You About 728: Why Brain Fog Isn’t Random: The Hormone Shift Behind It 769: Is It Perimenopause or Something Else?

What if you’re not burned out? You’re still working. Still exercising. Still taking care of your family. Still getting everything done. From the outside, you look like you’re handling it all. But underneath that competence, your body may be keeping a very different score through your sleep, recovery, energy, mood, stress tolerance, and heart rate variability. In this episode, Dr. Mariza sits down with nutritionist, health and performance coach, and High Performance Health podcast host Angela Foster to unpack the difference between true resilience and simply becoming incredibly good at pushing through. Angela explains why changing hormones in midlife can expose the cost of years of chronic under-recovery, how HRV can offer clues about whether your training and lifestyle actually match your capacity, and why the workout that once energized you may now leave you depleted for days. They also share practical ways to build more recovery into a full life without abandoning your ambition, including walking, strength training, strategic HIIT, box breathing, the physiological sigh, morning light, intentional pauses, boundaries, and what Dr. Mariza calls “mindfulness snacks.” Because the goal isn’t to build a smaller life. It’s to build the energy, resilience, and capacity to keep living the big life you’ve worked so hard to create. ANGELA FOSTER Angela Foster is a nutritionist, health and performance coach, and host of the High Performance Health podcast. Her work focuses on helping ambitious women optimize their energy, hormones, resilience, and longevity without sacrificing the full lives they love. Drawing from her own journey through major depressive disorder and perimenopause, Angela combines lifestyle medicine, exercise, recovery, nervous system regulation, and performance data such as HRV to help women understand their individual capacity and build greater resilience. IN THIS EPISODE How to distinguish true resilience from simply getting really good at pushing through Why hormonal changes in midlife can expose years of chronic under-recovery How HRV can reveal whether your training load actually matches your recovery capacity Why HIIT may energize some women while leaving others depleted for days How walking, strength training, box breathing, and intentional recovery can support resilience Why small “mindfulness snacks” throughout the day can help regulate your nervous system What to investigate when you’re doing everything right but your HRV still isn’t improving How boundaries, asking for help, and taking things off your plate can actually expand your future capacity Why sustainable ambition doesn’t require giving up the career or life you’ve worked hard to build QUOTES“The biggest stress for us is when we don’t feel that sense of self-agency.” “When you put intentional pauses into your day, you can slow that down and be present.” “Where in your life can you put an anchor in your day that just grounds you back to what’s important?” RESOURCES MENTIONED Find inspiration, connection, and meaningful reads.

You’re exhausted by 2 or 3 PM. Your workouts suddenly wipe you out. Your hair is shedding, your brain feels foggy, and even climbing a flight of stairs leaves you more winded than it used to. Then you finally ask for help and hear: “Your labs are normal.” In this solo episode, Dr. Mariza breaks down one of the most commonly missed contributors to persistent fatigue in women: iron deficiency, even before anemia develops. She explains newly released American Society of Hematology ferritin thresholds and why women who were previously told their iron was “normal” may deserve a closer look. But iron is only one part of the conversation. Dr. Mariza walks through the bigger clinical picture she considers when a woman says, “I don’t feel like myself anymore,” including thyroid function, mitochondrial energy production, blood sugar, sleep, nutrition, stress physiology, and HPA-axis regulation. Most importantly, she explains why fatigue is a symptom, not a diagnosis and why neither stress, aging, nor perimenopause should automatically become the explanation for everything you’re experiencing. Listen now to learn what may be hiding behind your exhaustion and how to have a more productive conversation with your healthcare provider. IN THIS EPISODE Why iron deficiency can exist before you become anemic The new ferritin thresholds women should know about Why a lab’s reference range and a diagnostic threshold are not always the same thing Why heavy perimenopausal periods can increase your risk of depleted iron stores The fatigue, brain fog, headaches, hair shedding, and exercise intolerance that can overlap with perimenopause How iron, thyroid hormones, nutrition, blood sugar, sleep, and recovery influence mitochondrial energy production Why “adrenal fatigue” oversimplifies what may actually be happening with the HPA axis How under-fueling, over-training, poor sleep, circadian disruption, illness, and caffeine can add to the body’s total stress load The questions to ask when you know something has changed but your labs keep coming back “normal” QUOTES “You can be iron deficient before you ever become anemic.” “Two things can be true at once.” “I don’t want mitochondrial dysfunction to become another vague label we give an exhausted woman.” RESOURCES MENTIONED Find inspiration, connection, and meaningful reads.

The Missing Link Between Nutrients, Hormones & Energy with Ryan Woodbury

What if perimenopause isn’t simply changing your hormones, but revealing everything your body has been compensating for for years? In this episode, Dr. Mariza sits down with integrative medicine physician and women’s health expert Dr. Taz Bhatia for an incredibly personal conversation about what happens when the strategies that helped high-functioning women push through for decades suddenly stop working. Dr. Taz shares how her own perimenopause began with incredibly heavy periods, fatigue, anemia, hair loss, mood changes, and unexpected weight gain. But one of her biggest surprises came later: as progesterone and estrogen declined, her blood sugar, insulin, cholesterol, A1C, and liver enzymes began creeping upward, revealing just how interconnected hormones and metabolic health really are. They also explore the emotional transformation of midlife: letting go of people-pleasing, protecting your energy, releasing the need to be the “good girl,” and becoming clearer about who you are and what deserves your attention. Listen now to rethink perimenopause as an opportunity to understand your body, protect your health, and step powerfully into what comes next. DR. TAZ BHATIA Dr. Taz Bhatia is a board-certified integrative medicine physician, women’s health expert, and bestselling author of several books, including The Hormone Shift. Her work explores the connections between hormones, metabolism, stress, nutrition, and whole-body health. Through her Whole Plus clinics and podcast, Dr. Taz advocates for a more collaborative approach to women’s health that looks beyond symptoms to cognitive, metabolic, cardiovascular, bone, mental, and hormonal health. IN THIS EPISODE How extremely heavy periods became Dr. Taz’s first undeniable sign of perimenopause Why weight gain in midlife isn’t necessarily something women simply have to accept How estrogen and progesterone shifts can intersect with blood sugar, insulin, cholesterol, and visceral fat Why the “silent” cardiometabolic changes of menopause deserve more attention Why your body may stop tolerating the stress, sleep debt, and depletion you once pushed through How perimenopause helped Dr. Taz stop people-pleasing and build stronger boundaries Why knowing your own patterns and tracking changes can help you advocate for yourself How midlife can become an opportunity to redefine your identity, purpose, and power QUOTES Perimenopause is really where women come into their own.” “These are not my battles. This is not my fight.” “We gotta redefine what fine is.” RESOURCES MENTIONED Find inspiration, connection, and meaningful reads: Join my Soulful Shelf Book Club (no cost) here: https://drmariza.com/bookclub Join my brand-new Substack: for the woman everyone depends on who is wondering why everything feels harder in midlife: https://drmariza.substack.com/ The Hormone Shift by Dr. Taz Bhatia: https://amzn.to/4xJ5VfK The Superwoman Rx by Dr. Taz Bhatia: https://amzn.to/4hHkZpn Dr. Taz Website: https://doctortaz.com/ Dr. Taz Instagram Hol+ Wellness Podcast RELATED EPISODES  775: Wide Awake at 3 A.M.?

What if one of the biggest questions of perimenopause isn’t simply “How do I feel better right now?” but “Who do I want to be 20, 30, or 40 years from now?” In this deeply personal conversation, Dr. Mariza sits down with women’s health expert Dr. Stephanie Estima to talk about the side of midlife that rarely makes it into conversations about hormones. They explore what happens when the high-functioning woman who has always been able to handle everything begins to notice that her capacity has changed. Stephanie shares how she can no longer work the same 10- or 12-hour days she once could, why movement has become essential for her mental clarity, and how perimenopause has made her more discerning about where she puts her energy. But this conversation goes much deeper than symptoms. From female friendship and motherhood to living according to your values, Stephanie and Mariza ask what it actually means to build a life and body capable of carrying you through the second half of your life. You’ll also hear Stephanie’s non-negotiables for longevity, including strength, mobility, joint health, pelvic floor health, and the small habits that compound over decades. Listen now and start training for the woman you still want to become. DR.

Have you ever looked at the same life you were managing a year ago and wondered, “Why does everything suddenly feel so hard?” You’re still ambitious. You’re still capable. You’re still the woman everyone depends on. But the stress you once brushed off gets under your skin. Your brain doesn’t feel as sharp. Sleep is changing. Your patience is shorter. And keeping all those plates spinning suddenly requires far more energy. In this solo episode, Dr. Mariza explores what happens when the profound hormonal and neurological changes of perimenopause collide with decades of over-functioning. She introduces what she calls the midlife capacity gap: the disconnect between the enormous load many women are carrying and the biological capacity they currently have to sustain it. You’ll learn why simply pushing harder may widen that gap, how Dr. Mariza is redefining resilience, and why supporting your hormones, brain, metabolism, muscle, and sleep is only part of the conversation. Because the goal isn’t to make your life smaller. It’s to build a body capable of sustaining the life you actually want while becoming far more discerning about what deserves your energy. Listen now to rethink what resilience looks like in midlife and start protecting your capacity for what truly matters. IN THIS EPISODE Why high-functioning women can feel blindsided by perimenopause What happens when the woman who always handles everything suddenly has less capacity How estrogen and progesterone shifts can affect your brain, sleep, mood, and stress response What over-functioning looks like and why it often gets rewarded The midlife capacity gap between the load you carry and your biological capacity Why pushing harder and becoming more disciplined may not be the answer How to redefine resilience around adapting, recovering, restoring, and thriving The question Dr. Mariza wants you asking: “Is this actually mine to carry?” QUOTES “Perimenopause doesn’t arrive in a vacuum.” “Endurance is not resilience.” “Doing less isn’t the same as caring less.” RESOURCES MENTIONED Order my newest book: The Perimenopause Revolution Stop surviving and start thriving, join Midlife on Fire Collective now The High Functioning Woman on Substack RELATED EPISODES  771: Beyond Hot Flashes: The 103 Symptoms of Perimenopause No One Talks About with Andrea Donsky 769: Is It Perimenopause or Something Else?
