The night before my kids, husband, and I were heading to a World Cup game, and I had a massive panic attack.
Not a quiet, manageable wave of anxiety. We're talking a full-blown panic attack. Heart racing. Tight chest. Dissociating from the room. Inability to sit still. Fear I could not locate or name flooding my body in a way that made absolutely no rational sense given where I was and what we were getting ready to do.
I love my kids. I was excited for this trip. There was no immediate threat.
But my nervous system did not get that memo. It had decided, somewhere beneath the level of conscious thought, that this was dangerous. That the unknown of it, the crowd, the train, the unpredictability of a big public event, was something to brace against. And it braced, hard, in a way I had never quite experienced before.
I've been through hard things, so I know what fear feels like. But this was different. This was my body responding to something my mind hadn't agreed to, in a way that felt completely out of proportion to the moment.
I'm in perimenopause. And what I understand now, that I didn't fully understand then, is that my nervous system is going through something real and physiological. Not a phase. Not me being too sensitive. A genuine neurological recalibration that nobody really prepares you for.
This post is what I wish someone had handed me before that train ride.
What Is Actually Happening in Your Brain During Perimenopause?
Most of what we hear about perimenopause focuses on the reproductive symptoms. Irregular periods. Hot flashes. Night sweats. These are real, and they matter.
But what the conversation consistently leaves out is this: perimenopause is not just a reproductive transition. It is a neurological one.
Estrogen and progesterone are not simply reproductive hormones. They are deeply involved in how your brain functions, how your nervous system regulates stress, and how your body manages anxiety, mood, focus, and sleep. When these hormones begin to fluctuate erratically, which is what happens in perimenopause, the effects reach far beyond your cycle.
Progesterone in particular has a calming, anti-anxiety effect because it supports GABA activity in the brain. GABA is your nervous system's primary calming neurotransmitter, the chemical signal that tells your brain it's safe to settle. When progesterone drops or becomes unpredictable, GABA activity decreases. The result is a nervous system that is more reactive, more easily activated, and slower to recover from stress than it used to be. [Source: The Breath Effect]
Estrogen fluctuations increase nervous system sensitivity even further, making stress feel sharper and recovery feel slower. Strategies that used to work, the deep breath, the walk, the good night's sleep, may suddenly feel less effective. Not because you've lost your capacity for regulation. Because the underlying chemistry has changed.
This is why perimenopause anxiety can feel completely unfamiliar. Like it arrived from nowhere. Like it doesn't belong to you. It's not a character change. It's a hormonal one.
Why Does Brain Fog Feel So Disorienting?
Because it is. And because what's happening in the brain during perimenopause is genuinely significant.
Estrogen plays a key role in cerebral blood flow, glucose metabolism in the brain, and the function of the hippocampus, the region most involved in memory, learning, and emotional regulation. When estrogen levels fluctuate dramatically, the brain's metabolic efficiency decreases. Researchers describe this as a state of low-grade neuroinflammation, what one source calls "biological static" — a slowing of synaptic transmission that impairs executive function, short-term memory, word retrieval, and focus.

And when progesterone drops and sleep becomes lighter and more fragmented, the brain fog deepens further. Deep sleep is when the brain consolidates memory and clears metabolic waste. Without it, cortisol rises, hippocampal function is further impaired, and the fog thickens. Brain fog and sleep disruption in perimenopause are not two separate symptoms. They are two ends of the same hormonal chain. [Source: Cleopatra Rx]
I want to say something clearly here: if you've been losing words mid-sentence, walking into rooms and forgetting why, feeling like your mind is working through static, you are not losing your mind. You are navigating a brain that is adapting to a significant hormonal shift. That is not the same thing.
Why Does Perimenopause Feel Like Losing Yourself?
This is the part nobody talks about enough. And it's the part that I find most tender.
The physical changes are real, and they compound. Weight that redistributes without warning. Skin that shifts. Hair that changes texture. A body that no longer responds to the things that used to work. And underneath all of it, a slow, disorienting renegotiation with the version of yourself you thought you knew.
We live in a culture that has very specific things to say about women's bodies as they age. About youth and vitality and attractiveness and visibility. And perimenopause arrives right in the middle of that cultural noise and says: your body is changing, whether the world makes room for that or not.
I have felt invisible in ways I didn't expect. I have felt older in ways that stopped me mid-thought. I have looked in the mirror and had to make room for something I wasn't prepared for, not grief exactly, but something adjacent to it. A reckoning with impermanence. A reminder, quiet but persistent, that time is moving and the body is keeping count.
This one is not a wellness problem to solve... It is a human experience to be honored.
What I've come to understand is that perimenopause is not the beginning of the end. But it does ask something of you. It asks you to learn your body all over again. To stop relating to it through the lens of what it used to do or what the culture says it should look like and start relating to it through the lens of what it is actually telling you, right now, in this season.
That is genuinely hard work. And it deserves more than a supplement recommendation.
Why Do Old Coping Tools Stop Working?
Because the nervous system underneath them has changed.
If you have spent years building a toolkit- meditation, breathwork, exercise, journaling- and you find that in perimenopause those tools feel less effective than they used to, you are not doing them wrong. The threshold has shifted. The nervous system is more sensitive, more reactive, and needs more consistent, layered support than it did before.
This is where small, sensory, body-based tools become especially valuable. Not as replacements for the deeper work, but as what I call micro-supports. Tiny inputs throughout the day that keep the nervous system from accumulating into overwhelm.
Scent is one of the fastest of these. When you inhale a botanical aroma, it reaches the limbic system, the brain's emotional regulation center, faster than almost any other sensory input. For a nervous system that is running hotter than usual, that speed matters. A grounding botanical spray used consistently at transition moments throughout the day becomes a cue. A signal. A small, repeated message to the body that it is safe to come down.
This is exactly what North was built for. Not as a cure for perimenopause. But as one steady, beautiful, accessible tool for a nervous system that is working harder than it used to, and deserves more support than it's been given.
What Actually Helps?
I want to be careful here because perimenopause is a medical and hormonal transition and deserves proper care. If your symptoms are significantly impacting your quality of life, please talk to a healthcare provider who specializes in women's hormonal health. Hormone therapy, when appropriate, can be genuinely life-changing for some women and deserves a real conversation without dismissal.
Beyond that, here is what the research and my own experience point to:
Nervous system support as a daily practice, not an occasional event. The more sensitive and reactive your nervous system has become, the more consistently it needs grounding inputs. Breathwork, somatic movement, and sensory tools like botanical aromatherapy work best when they're woven into the ordinary moments of the day rather than saved for crisis.
Radical sleep prioritization. Sleep is when the brain clears, regulates cortisol, and consolidates memory. In perimenopause, when sleep becomes more fragmented, protecting it becomes more important, not less. Consistent bedtime rituals using calming botanical cues, like lavender and vetiver, can help signal the nervous system toward rest.
Letting the body change without making it wrong. This is the hardest one. The weight that won't shift the way it used to, the skin, the energy, the way you look in the mirror. Your body is not failing. It is transitioning. The nervous system regulation piece includes how you speak to yourself about what you're experiencing.
Community. Your nervous system regulates in relationship. Finding women who are in this same season, who can name what you're feeling without minimizing it, is not a luxury. It is physiological medicine.
FAQ: Perimenopause, Anxiety, and the Nervous System
Why has my anxiety gotten so much worse in perimenopause? Because progesterone, which supports GABA activity in the brain (your primary calming neurotransmitter), decreases and becomes erratic during perimenopause. At the same time, estrogen fluctuations increase nervous system sensitivity. The result is a nervous system that is more easily activated and slower to recover than it used to be. This is physiological, not psychological.
Is perimenopause brain fog real? Yes, and it has a measurable neurological basis. Estrogen plays a key role in cerebral blood flow and brain metabolic efficiency. When estrogen fluctuates, the brain's processing slows, producing the cognitive symptoms women describe as fog, word loss, forgetfulness, and difficulty focusing.
Why do my old coping strategies feel less effective? Because the nervous system underneath them has changed. Perimenopause increases the nervous system's baseline sensitivity and reactivity, which means tools that used to work may need to be supplemented with more frequent, more layered support. This is not failure. It is adaptation.
Can aromatherapy help with perimenopause anxiety? Research supports aromatherapy, particularly botanical essential oils like lavender and rose, as a complementary support for anxiety, mood, and nervous system regulation during hormonally sensitive life stages. [Source: MDPI, Aromatherapy in Women's Mental Health, 2026] It works best as part of a consistent daily ritual rather than an occasional response to acute symptoms.
Is weight gain during perimenopause inevitable? Hormonal shifts, particularly changes in estrogen and cortisol, do affect how the body stores fat, particularly around the abdomen. This is a documented physiological change, not a personal failure. Supporting the nervous system and cortisol regulation through consistent grounding practices, sleep, and stress reduction can be part of a broader approach, though this is a conversation worth having with a healthcare provider.
When should I talk to a doctor about perimenopause symptoms? If your symptoms are significantly disrupting your sleep, mental health, relationships, or daily functioning, please seek care from a provider who specializes in women's hormonal health. You deserve to be taken seriously and to have access to the full range of options available, including hormone therapy if appropriate. You do not have to white-knuckle your way through this transition.
You Are Not Losing Yourself. You Are Changing.
Perimenopause is asking you to learn your body all over again. To stop measuring yourself against who you were and start listening to who you are becoming.
That is uncomfortable. It is also, in its own way, an invitation.
An invitation to tend to yourself with the same care you have given everyone else for years. To build a daily practice of returning to your body rather than pushing through it. To find the tools, the community, and the honesty that this season actually requires.
North was built for exactly this kind of season. Not as a solution to something that doesn't need solving, but as a daily companion for a nervous system doing the most.
One breath. One moment. One small act of coming home.
You are your own sanctuary. The tools are simply how you remember.
