The Regulated Woman

The average lifestyle today is fundamentally mismatched with human biology.

Highly processed foods lack the micronutrients required for proper brain and nervous system function (Bird et al., 2017; Das et al., 2025).

Chronic psychological stress keeps the body in a constant state of vigilance (Knezevic et al., 2023).

Artificial light exposure extends the day far beyond natural limits, disrupting circadian rhythms (Cajochen et al., 2011).

Time spent indoors replaces time in nature, removing essential environmental inputs that support immune and nervous system balance (Khaira, 2020; Chatterjee, 2022).

These factors do not act independently—they compound.

A nutrient-deficient body is less resilient to stress (Das et al., 2025).

A sleep-deprived brain is more reactive (Scheer et al., 2009).

A chronically stressed nervous system alters food cravings, hormone production, and metabolic function (Joseph & Golden, 2016).

Over time, this creates a feedback loop of dysregulation.

At the most basic level, the nervous system depends on nutrients.

Micronutrients such as B vitamins, magnesium, iron, zinc, and omega-3 fatty acids are required for:

• Neurotransmitter synthesis (serotonin, dopamine, GABA) (Das et al., 2025)
• Energy production in brain cells (Das et al., 2025)
• Myelin formation and nerve signaling (Das et al., 2025)
• Protection against oxidative stress (Das et al., 2025)

When these nutrients are lacking, the brain cannot regulate itself effectively (Das et al., 2025).

This can manifest as:

• Anxiety and mood instability (Das et al., 2025)
• Brain fog and poor focus (Das et al., 2025)
• Fatigue and low motivation (Das et al., 2025)
• Increased stress sensitivity (Das et al., 2025)

Importantly, deficiencies are not rare.

They are seen in nearly one-third of the population (Bird et al., 2017).

Even mild deficiencies can significantly impact nervous system function over time.

Food is not just fuel. It is information that tells the nervous system how to operate (Das et al., 2025).

Magnesium is involved in over 300 biochemical reactions, many directly related to stress and nervous system function (Volpe, 2013).

It helps regulate excitatory and inhibitory signals in the brain, supporting a shift away from overstimulation (Volpe, 2013).

Low magnesium levels are associated with:

• Increased anxiety and irritability (Volpe, 2013)
• Poor sleep quality (Volpe, 2013)
• Muscle tension (Volpe, 2013)
• Heightened stress response (Volpe, 2013)

Magnesium also supports blood sugar stability, which is essential for maintaining emotional and physiological balance (Volpe, 2013).

Blood sugar crashes can trigger stress hormones, further dysregulating the system.

In many ways, magnesium acts as a biological “brake pedal” for the nervous system (Volpe, 2013).

The nervous system does not function in isolation—it operates on a daily rhythm.

Circadian rhythms regulate:

• Sleep and wake cycles (Scheer et al., 2009)
• Hormone release (including cortisol and melatonin) (Scheer et al., 2009; Cajochen et al., 2011)
• Metabolism and digestion (Scheer et al., 2009)
• Body temperature and energy levels (Scheer et al., 2009)

Modern light exposure—especially blue light from screens at night—disrupts these rhythms (Cajochen et al., 2011).

When melatonin production is suppressed, the body struggles to transition into restorative sleep (Cajochen et al., 2011).

This leads to:

• Delayed sleep onset (Cajochen et al., 2011)
• Reduced sleep quality (Scheer et al., 2009)
• Increased nighttime alertness (Cajochen et al., 2011)
• Impaired recovery (Scheer et al., 2009)

Over time, circadian disruption alters cortisol patterns, leading to either excessive or insufficient stress hormone output (Joseph & Golden, 2016).

When lifestyle behaviors (eating, sleeping, working) are out of sync with the body’s internal clock, the consequences extend beyond sleep.

Circadian misalignment has been shown to:

• Increase blood glucose and insulin levels (Scheer et al., 2009)
• Decrease leptin (the hormone that regulates hunger) (Scheer et al., 2009)
• Raise blood pressure (Scheer et al., 2009)
• Disrupt cortisol rhythms (Scheer et al., 2009)

Even short-term disruption can push the body toward a pre-disease state (Scheer et al., 2009).

When we live out of sync with natural rhythms, the body experiences it as stress (Scheer et al., 2009).

This system controls the release of cortisol, the body’s primary stress hormone (Joseph & Golden, 2016).

In a healthy system:

• Cortisol rises in the morning (to wake you up) (Joseph & Golden, 2016)
• Gradually declines throughout the day (Joseph & Golden, 2016)
• Reaches its lowest point at night (Joseph & Golden, 2016)

In chronic stress, this rhythm becomes disrupted (Joseph & Golden, 2016; Knezevic et al., 2023).

The result can be:

• A flattened cortisol curve (Joseph & Golden, 2016)
• Low energy in the morning (Knezevic et al., 2023)
• Wired but tired at night (Knezevic et al., 2023)
• Increased inflammation (Knezevic et al., 2023)
• Blood sugar dysregulation (Joseph & Golden, 2016)

Stress and disease begin to reinforce each other, creating a nefarious cycle that is difficult to break without intervention (Joseph & Golden, 2016).

The autonomic nervous system has two primary branches:

• Sympathetic (“fight or flight”)
• Parasympathetic (“rest and digest”)

In modern life, many women live in a state of sympathetic dominance (Sohn & Jenei-Lanzl, 2023).

This state prioritizes survival over long-term health.

Functions like digestion, reproduction, and repair are downregulated, while vigilance and energy mobilization are prioritized.

Chronic sympathetic activation is associated with:

• Inflammation (Sohn & Jenei-Lanzl, 2023)
• Digestive dysfunction (Sohn & Jenei-Lanzl, 2023)
• Hormonal imbalance (Joseph & Golden, 2016)
• Anxiety and hypervigilance (Knezevic et al., 2023)
• Burnout (Romm, 2024a)

The body is not malfunctioning—it is adapting to perceived threat.

Hormonal systems are deeply interconnected with the nervous system (Joseph & Golden, 2016).

This means that stress, sleep disruption, and nutrient deficiencies can quickly translate into hormonal symptoms.

Additionally, women often carry:

• Higher emotional and caregiving loads (Romm, 2024b)
• Greater societal pressure (Romm, 2024b)
• More chronic, low-grade stress (Knezevic et al., 2023)

Over time, this increases vulnerability to nervous system dysregulation.

Symptoms often labeled as “hormonal issues” are frequently rooted in nervous system imbalance (Joseph & Golden, 2016).

One of the most important concepts in healing is neuroplasticity.

The brain and nervous system are not fixed—they adapt based on experience and input (Calderone et al., 2024).

This means:

• Stress patterns can be unlearned (Calderone et al., 2024)
• Calm states can be strengthened (Calderone et al., 2024)
• Emotional regulation can improve (Calderone et al., 2024)

Your nervous system is constantly asking:
“Am I safe?”

Your daily habits answer that question (Huberman, 2023).

They can:

• Reduce activity in the amygdala (fear center) (Calderone et al., 2024)
• Increase cortical thickness in areas related to regulation (Calderone et al., 2024)
• Improve connectivity between brain regions (Calderone et al., 2024)
• Lower cortisol levels (Calderone et al., 2024)

Over time, mindfulness shifts the baseline state of the nervous system from reactive to regulated.

This is not just psychological but biological change.

Oxytocin is often called the “bonding hormone,” but its role is much deeper.

It acts as a buffer against stress (Takayanagi & Onaka, 2021).

Oxytocin:

• Reduces HPA axis activation (Takayanagi & Onaka, 2021)
• Lowers anxiety (Takayanagi & Onaka, 2021)
• Decreases inflammation (Takayanagi & Onaka, 2021)
• Enhances feelings of safety and trust (Takayanagi & Onaka, 2021)

It also promotes resilience (your ability to recover from stress) (Takayanagi & Onaka, 2021).

Importantly, oxytocin is highly influenced by behavior and environment.

This includes:

• Physical touch (hugs, massage) (Takayanagi & Onaka, 2021)
• Meaningful social interaction (Takayanagi & Onaka, 2021)
• Eye contact and emotional presence (Takayanagi & Onaka, 2021)
• Acts of kindness and generosity (Huberman, 2023)
• Feeling supported and understood (Takayanagi & Onaka, 2021)

These are not “extras” but instead biological requirements for regulation.

Time in nature provides:

• Sensory grounding (Khaira, 2020)
• Exposure to beneficial microbes (Chatterjee, 2022)
• Reduced stress hormone levels (Khaira, 2020)
• Increased parasympathetic activity (Khaira, 2020)

Practices like walking in nature, touching the earth, or simply being outdoors can shift the nervous system toward regulation.

Health is not determined by a single factor.

It emerges from the interaction between:

• Nutrition (Das et al., 2025)
• Environment (Chatterjee, 2022)
• Microbiome (Chatterjee, 2022)
• Stress levels (Knezevic et al., 2023)
• Social connection (Takayanagi & Onaka, 2021)

A reductionist approach—treating isolated symptoms—misses the bigger picture.

True healing requires restoring relationships within the system.

Adaptogens are herbs that help the body regulate its stress response.

They work by supporting the HPA axis and improving resilience (Romm, 2024a).

Some are calming and restorative, while others are stimulating. Matching the herb to the individual’s state is essential (Romm, 2024a). Don't use a stimulating adaptogen if you are already in overdrive.

They are not a replacement for lifestyle change, but they can support recovery when used appropriately. Examples include ashwaganda and reishi. 

Many people today exist in a state of continuous low-grade stress.

This “always on” survival mode leads to:

• Emotional exhaustion (Romm, 2024b)
• Reduced capacity to cope (Romm, 2024b)
• Hormonal disruption (Romm, 2024b)
• Increased inflammation (Knezevic et al., 2023)

Over time, the body loses its ability to return to baseline.

This is physiological overload. 

Key areas include:

• Nutrient-dense, mineral-rich nutrition (Das et al., 2025; Volpe, 2013)
• Consistent sleep and circadian alignment (Scheer et al., 2009)
• Stress regulation practices (Calderone et al., 2024)
• Social connection and emotional safety (Takayanagi & Onaka, 2021)
• Time in nature (Khaira, 2020)

Each of these signals safety to your body.

Food does more than provide calories.

It communicates:

• Whether resources are abundant or scarce (Das et al., 2025)
• Whether the body can relax or must stay alert (Joseph & Golden, 2016)
• Whether repair and reproduction are safe (Joseph & Golden, 2016)

Whole, nutrient-dense foods support stability (Bird et al., 2017).

Highly processed foods can create volatility in blood sugar and energy, increasing stress signals (Joseph & Golden, 2016).

Small daily behaviors shape the nervous system over time.

• Morning sunlight anchors circadian rhythm (Scheer et al., 2009)
• Reducing blue light supports sleep (Cajochen et al., 2011)
• Movement regulates stress hormones (Huberman, 2023)
• Time offline reduces overstimulation (Cajochen et al., 2011)

Consistency is key.

Simple, consistent practices can shift the nervous system:

• Breathwork (Huberman, 2023)
• Meditation (Calderone et al., 2024)
• Walking outdoors (Khaira, 2020)
• Journaling (Huberman, 2023)
• Intentional rest (Romm, 2024b)

These practices work by activating the parasympathetic system and reinforcing safety signals.

Nervous system dysregulation is not an individual failure but  a systemic response to modern conditions.

Your body is not broken.

It is responding exactly as it was designed to (Huberman, 2023).

Healing comes from:

• Understanding the system (Chatterjee, 2022)
• Addressing root causes (Romm, 2024a)
• Creating environments that support regulation (Calderone et al., 2024)
