You’ve built a career and a reputation for delivering results, but lately, your body isn’t cooperating the way it used to.

You’re used to running the show, making decisions, leading with clarity, and juggling multiple responsibilities, but you’ve felt a shift since you’ve entered your 40s. Suddenly, the focus you once relied on isn’t as sharp, your energy goes missing when you need it most, and your body feels like it’s rebelling against your ambitions.

Maybe brain fog is clouding your decision making, or hot flashes are flaring in the middle of a meeting…Or maybe fatigue is crushing your ability to deliver the way you used to…and all you can think about is how many hours you have to make it through before you can crawl into bed.

These changes aren’t just inconvenient, they can chip away at your confidence, your leadership, and even influence the way you see yourself.

This is where it goes very wrong…You start to blame yourself and push harder, thinking you’re the problem. You shift into self-talk about discipline and willpower, you double-down on working harder…After all, it worked in the past. But this time, it’s different. What you’re experiencing now isn’t a failure of drive or leadership—you still have those things. This time, it’s your body signaling that your hormones are shifting.

You’re not alone. I’ve been there, too! And I’ve helped other women in leadership experiencing the same story…Brilliant, capable women who suddenly feel like their edge is slipping. Not because they’re losing their ambition or talent, but because their biology is changing in a way no one prepared them for.

The good news? Once you begin to understand what’s happening, and how to support your body through this season, you can stop fighting and trying to force things, and you can start leading with clarity and confidence again.

That’s why I’m sharing three key insights that every high-achieving woman should know about perimenopause hormones (because this is about more than hot flashes). You’ll understand how these changes impact your energy, focus, mood, and more…and why boundaries aren’t just about work-life balance, they’re a non-negotiable part of protecting your health, and your ability to thrive in perimenopause and beyond.

Knowing what’s really happening will keep you from getting lost in the weeds and white-knuckling your way through perimenopause, so you can start creating space for strategies that support your body in a sustainable way for the season you’re in.

HORMONES INFLUENCE MORE THAN HOT FLASHES

Culturally, we’ve been trained to understand midlife hormones based on outdated stereotypes and medical treatments that have ignored the real underlying problems. Hot flashes have hogged the spotlight because they’re obnoxious, yet they’re socially acceptable to discuss. The truth is that hormones influence functions throughout your body and affect more than just sexual function…They affect your energy, focus, mood, memory, and more—which matters to your leadership.

Estrogen (estradiol) plays a role in memory, mood stability, and your ability to handle stress. When levels fluctuate, it’s common to feel less sharp and more irritable under pressure. Progesterone, a calming hormone, helps with sleep and emotional resilience. When it drops, women often notice restless sleep, more anxiety, and a shorter fuse which can be disturbing. Cortisol, your stress hormone, can be helpful to keep you going and responsive to “fires”, but it leaves you wired-but-tired at night, and exhausted during the day when it gets out of balance.

Think of it like this: Your hormones are like the internal communication channels of your team. When communication is clear, everyone is in sync, the team thrives and success is the inevitable. When a message is confusing, or when a critical player goes silent, teamwork is less effective because the rhythm is lost. Projects stall, misunderstandings happen, and chaos spreads. That’s exactly what’s happening in your body when your hormones shift. It’s not that you’re suddenly incapable, it’s that your internal communication system has gone out of sync.

When that internal chaos shows up externally, it might look like struggling to make confident decisions, losing patience with your team, or blanking out on a critical detail during a presentation or in a meeting. These ripple effects aren’t random glitches, they’re systemic effects of midlife hormone shifts.

Here’s the good news…Once you understand the hormone connection, you can stop blaming yourself and start supporting your body.

STRESS MAKES HORMONE CHAOS EVEN LOUDER

If shifting hormones were a spark, then stress would be like adding gasoline. The demanding pace of leadership may not have affected you as much in the past, but in perimenopause, stress magnifies the hormone shifts.

Cortisol, your primary stress hormone, is designed to help you rise to the occasion in short bursts. Imagine if you were running from a bear…Cortisol sharpens focus, mobilizes energy, and keeps you alert. But for a woman over 40 in leadership…deadlines, a plethora of professional and personal commitments, information overload and back-to-back daily challenges can shift cortisol into overdrive. Instead of powering you through an occasional crisis, it’s showing up 24/7.

Here’s how that shows up in your real life:

Sleep disruption: High cortisol levels at night can set your brain up to be wired even when you’re tired. You may find yourself tossing and turning instead of getting the restorative sleep you need.

Brain Fog: Chronic stress drains mental clarity, making focus and memory issues more common.

Mood Swings and Irritability: Cortisol pushes your body into fight-or-flight mode, making it harder to stay calm and cool under pressure. Couple this with declining progesterone levels and anxiety may also rear its head.

Belly Fat: High cortisol levels can promote belly fat storage and can fuel cravings, causing weight gain which can be especially frustrating for women who are watching what they eat and staying active.

This is why so many high-achieving women are blindsided during perimenopause. Your body is trying to adapt at a time when stress resilience is lower than ever. Stress hormone and sex hormone changes are all happening at once. I’ve seen this pattern play out time and again as I’ve worked with women who lead. When stress is high, symptoms hit harder, last longer, and feel more disruptive.

And while you may not be able to control the demands of leadership and life, you can change how you respond to them…And that’s where boundaries come in—not as a “someday” or “nice to have”, but as a hormone health strategy.

BOUNDARIES: A HORMONE HEALTH STRATEGY

When hormones are shifting and stress is high, your body has less capacity to deal with nonstop demands. That’s why boundaries are not just about work-life balance. Boundaries are also a necessary strategy for protecting your hormone health.

While my expertise is nutrition and I often suggest powerful tools like nutrient dense diets, lab testing, supplements, and lifestyle changes, the truth is that even the best protocols won’t work if you’re running on empty with no space to recharge. Boundaries are necessary to create white space in your life.

Here are just a few practical ways boundaries can support your hormones and your leadership in midlife:

Saying no to extra commitments: Just because you are capable, doesn’t always mean you should. Declining extra assignments whether it’s a new committee, or even volunteer role can create margins for recharging and recovery when energy is in short supply.

Phone-Off hours: Turning off devices after hours helps calm the nervous system, allowing cortisol to downshift, and melatonin to rise to prepare you for sleep.

Protecting sleep: Treating bedtime as a non-negotiable meeting with yourself will go a long way to restoring energy levels and recharging. This can be a big lever in your quest for regulating hormone balance.

Buffer zones: Build space in your calendar between meetings. Adding 15 minutes to breathe deeply, hydrate, or even make sure you get to eat can prevent cortisol spikes that derail your energy and further deplete hormones.

Delegating: Trusting others is key to success here, but that takes practice. Delegating responsibilities to your team or to family members allows you to share the load and is the path to sustainable leadership and health.

Setting boundaries isn’t an act of selfishness. It is a necessary strategy that can uplevel your leadership and your hormone health in perimenopause and beyond. In the same way that clear communication keeps your team aligned and effective, clear boundaries protect your energy, clarity, and peace of mind. And when you model this, you don’t just protect your own health, you are teaching those around you to do the same.

The women I’ve worked with who embrace boundaries, don’t just feel better physically, they also become better leaders who make better decisions, lead with patience. They’re more present in both their professional and personal lives because they have created the space to thrive.

UPLEVELING YOUR LEADERSHIP

You don’t have to white-knuckle your way through perimenopause hoping the symptoms will eventually disappear. You don’t have to push harder or prove your resilience…I haven’t seen anyone giving out awards for this yet! This is the time for supporting your body with the strategies it needs to work for you and not against you.

When you understand how your hormones are affecting your energy, focus, and moods, you’ll be equipped with the knowledge and motivation to set smart boundaries that create an environment you can thrive in for both your leadership and your life.

Here’s the truth:

1.       Hormones influence a whole lot more than hot flashes. They shape how you think, feel and show up to lead.

2.       Stress amplifies hormone chaos. Without rest and recovery, the symptoms multiply.

3.       Boundaries are NOT selfish…They are a strategic investment in your health and your leadership.

With the right support, you can reclaim your energy, clarity, and confidence to lead your team, your family, and yourself.
