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.

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.”

What if the brain fog, overwhelm, time blindness, racing thoughts, and shorter emotional fuse showing up in your 40s aren’t just perimenopause?

For many women, ADHD has been hiding in plain sight for decades.

In this episode, Dr. Mariza sits down with women’s hormone expert and author Dr. Jolene Brighten to unpack why ADHD looks so different in women, why so many girls learn to mask their symptoms, and why changing estrogen levels during perimenopause can make those coping strategies suddenly stop working.

Dr. Brighten explains how ADHD in women may look less like the stereotypical hyperactive child and more like people-pleasing, perfectionism, constantly running mental lists, interrupting because you’re afraid you’ll forget your thought, chronic overwhelm, and appearing completely put together while internally struggling.

They also dive into the fascinating overlap between ADHD, perimenopause, PMDD, sleep, mitochondrial function, glucose metabolism, neuroinflammation, and emotional regulation.

And perhaps most importantly, they discuss what women can actually do: how movement can support brain energy, why sleep matters so much for the ADHD brain, how to build habits that work with your executive function instead of against it, and exactly how to advocate for a proper evaluation when your concerns are dismissed.

Because if your brain suddenly feels harder to manage in midlife, there may be more going on than “just hormones.”

DR. JOLENE BRIGHTEN

Dr. Jolene Brighten is a board-certified naturopathic endocrinologist, women’s hormone expert, educator, and bestselling author whose work focuses on helping women better understand the relationship between their hormones, brain, and overall health.

Her newest book, ADHD and Women: A Guide to Optimizing Your Hormones and Thriving with ADHD, explores how female hormones can influence ADHD symptoms throughout puberty, the menstrual cycle, pregnancy, postpartum, and perimenopause.

In this conversation, Dr. Brighten brings both clinical expertise and personal experience to the complicated intersection of ADHD, hormonal transitions, PMDD, emotional regulation, sleep, and women finally receiving answers after decades of believing they simply needed to try harder.

IN THIS EPISODE

Why ADHD in women can hide behind people-pleasing, perfectionism, and looking “high-functioning”

How declining estrogen in perimenopause can make masking ADHD symptoms much harder

Why girls with ADHD are often diagnosed with anxiety or depression instead

The connection between ADHD, mitochondrial function, brain glucose metabolism, and neuroinflammation

Why movement can temporarily improve focus and cognitive performance in the ADHD brain

How sleep disruption can compound brain fog, emotional dysregulation, and ADHD symptoms

What to track and say to your doctor if you suspect ADHD but keep getting dismissed

QUOTES

“Build pleasure into your day.”

“It is not just a hormone story.”

“High functioning is the label that society puts on women so that they can feel comfortable asking for more from her.”

661: When “Normal” Isn’t Normal: How to Be Heard (and Taken Seriously) at the Doctor’s Office

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?”

How did hormones become something women were taught to fear?

For decades, hormone therapy has been surrounded by confusion, conflicting recommendations, and sweeping assumptions that lump very different hormones and formulations together. Meanwhile, women continue walking into doctors’ offices saying, “I don’t feel like myself anymore,” and too often leave without answers or options.

In this episode, Dr. Mariza sits down in London with physician, women’s hormone specialist, educator, bestselling author, and advocate Dr. Louise Newson for a powerful conversation about how women’s hormone care got here and what needs to change.

They unpack why menopause has been reduced to hot flashes and night sweats, why estrogen, progesterone, and testosterone need far more nuance, and why Dr. Newson believes hormones deserve a place in the conversation about long-term health, not simply symptom relief.

They also go deep into one of the most controversial areas of women’s hormone care: testosterone, why the conversation so often begins and ends with libido, and what Dr. Newson has observed in women taking it for broader symptoms.

Most importantly, this episode is about informed choice: giving women accurate information, acknowledging where evidence is strong or still evolving, and creating healthcare relationships where women can participate fully in decisions about their own bodies.

DR. LOUISE NEWSON

Dr. Louise Newson is a physician, women’s hormone specialist, educator, bestselling author, and advocate working to transform the way women understand and access hormone care.

Her newest book, The Power of Hormones, explores the history of estrogen, progesterone, testosterone, hormone therapy, inflammation, and the medical decisions that have shaped women’s healthcare. Dr. Newson also focuses heavily on helping women understand their options and participate more actively in decisions about their health.

IN THIS EPISODE

Why menopause and hormone loss need to be viewed as more than hot flashes and night sweats

How decades of medical history shaped today’s fear and confusion around hormone therapy

Why lifestyle and hormone therapy should not be treated as an either-or decision

The controversy around testosterone for women and why the conversation extends beyond libido

Why the specific hormone and formulation matter when discussing benefits and risks

How hormone changes may influence metabolic health, inflammation, and healthy aging

The differences Dr. Newson draws between bioidentical hormones and synthetic hormone formulations

Why younger women with hormonal conditions such as PMDD deserve a deeper hormone conversation

How women can use knowledge, evidence, and informed choice to advocate for better healthcare

QUOTES

“You can only decide when you’ve got knowledge.”

“It’s all about choice based on evidence and fact.”

“We really need to grow up and think we need to prevent disease.”

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.”
