How Stressors Drain Your Energy, Hijack Your Brain and Lead to Burnout

Discover how everyday triggers keep your cortisol high, disrupt your brain chemistry, and what you can do to reclaim your energy.

How Stressors Drain Your Energy, Hijack Your Brain and Lead to Burnout

Does this sound familiar?

Meet Sarah. She’s 38, a senior manager, mother of two, and the kind of high achiever everyone admires. For years she thrived on multitasking—balancing deadlines, workouts, family life, and social commitments with apparent ease.

But lately? Sarah wakes up already tired. By mid-morning, her head feels foggy. She reaches for a second coffee just to think straight. The afternoon brings sugar cravings and energy crashes. And at night, when she finally wants to rest, her brain refuses to switch off.

👉 If this sounds familiar, know this: it’s not laziness, weakness, or lack of willpower. It’s the hidden cost of a cortisol imbalance—your biology quietly sounding the alarm.

What is Cortisol?

Cortisol is often called the stress hormone, but it’s much more than that. It’s produced by your adrenal glands and helps you wake up, fuel focus, regulate blood sugar, and keep your immune system strong. Think of it as your body’s built-in energy manager.

In a healthy rhythm, cortisol peaks in the morning and falls by night, making space for deep rest. But when it stays high all day—through stress, poor sleep, caffeine, or hidden hormone disruptors—it flips from ally to enemy.

👉 The result? Your brain’s natural messengers—the neurotransmitters that keep you calm, focused, motivated, and able to sleep—fall out of sync. You feel foggy, restless, anxious, and “wired but tired.” Over time, this imbalance chips away at productivity, joy, and resilience—pushing you toward burnout.

The 5 Cortisol Hijackers

  1. ☕ Caffeine – Quick energy, but overuse keeps cortisol high. Symptoms: racing thoughts, restless sleep, reliance on coffee.
  2. 🍩 Ultra-processed food – Blood sugar spikes keep the stress system activated, fueling cravings, brain fog, and afternoon crashes.
  3. 🌱 Pesticides & microplastics – Endocrine disruptors that mimic hormones and confuse your stress system.
  4. ⚡ Chronic stress – Deadlines, multitasking, overtraining. Cortisol floods until you feel wired but tired.
  5. 🌙 Sleep deprivation – Cortisol flips: instead of falling at night, it rises, wrecking recovery and next-day energy.

👉 We all know caffeine, sugar, and lack of sleep are culprits. But the real hidden stressors—pesticides and microplastics—are what most doctors never mention.

Pesticides & Microplastics: The Invisible Stressors

These endocrine disruptors mimic or block your natural hormones, confusing your body’s signals like a broken orchestra.

The HPA axis (your stress circuit):

  • Hypothalamus = the smoke detector
  • Pituitary = the alarm
  • Adrenals = the siren (cortisol release)

Disruptors send false alarms. Cortisol keeps rising.

The domino effect:

  • Estrogen dominance → PMS, heavier cycles, mood swings, stubborn weight.
  • Insulin resistance → cravings, afternoon crashes, belly fat.
  • The loop → Cortisol ↑, estrogen dominance ↑, insulin resistance ↑, stress axis stays locked “on.”

👉 Symptoms you may feel: waking up tired, brain fog, cravings, restless nights, feeling wired but tired.

Cortisol and Your Brain – The Neurotransmitter Chaos

Cortisol doesn’t just drain your body—it rewires your brain. High cortisol scrambles neurotransmitters—the brain messengers that normally keep your mood steady, your focus sharp, your motivation high, and your sleep deep.

In balance: Your brain feels clear, calm, and productive.

Out of balance: You get brain fog, irritability, procrastination, restless sleep, and exhaustion even after rest.

👉 This is why high achievers like Sarah struggle most. You’re still working as hard as before, but your brain chemistry isn’t backing you up. This is biology, not weakness.

Stress is Contagious – Especially for Leaders

Stress doesn’t stay inside you—it spreads.

  • Cortisol is released in sweat (Russell et al., 2014).
  • Others pick up “stress signals” unconsciously (Dalton et al., 2013).
  • Watching someone under pressure raised cortisol in 26% of observers (Engert et al., 2014).

👉 For leaders and high achievers, the effect is amplified: your stress sets the tone. Protecting your cortisol rhythm isn’t just self-care—it’s leadership.

Why Women and High Achievers Are Extra Vulnerable

Women run multiple calendars at once—career, kids, parents, home. High achievers push harder with coffee, workouts, and multitasking. The body reads it all as nonstop pressure.

👉 This isn’t failed willpower. It’s biology. And the harder you push, the more cortisol hijacks your system.

The Way Back – Practical Resets

Your biology isn’t broken. Even after years of stress, your system can reset. Here’s how:

  • 🧘 Breathe – Long exhale > inhale. Two minutes lowers cortisol.
  • 🚶 Move smarter – Walk, yoga, light training. Skip punishing HIIT when exhausted.
  • 🌙 Protect sleep rhythm – Digital sunset + ritual = cortisol drop at night.
  • 🥦 Eat steady energy – Protein + fiber + fats each meal stabilize blood sugar.
  • 📝 Release pressure – Journaling or talking resets your stress loop.
  • 💊 Smart support – Magnesium glycinate (calm, sleep), magnesium threonate (focus), B-vitamins, adaptogens.

🌟 Quick Wins You Can Try Today

  • Switch one coffee for herbal tea.
  • Add protein + fiber to your breakfast.
  • Do 5 minutes of breathwork with longer exhales.

✨ Imagine this (World B):

You wake up clear-headed, not foggy. You get through the day energized, not crashing. You handle pressure with calm focus instead of anxiety. You sleep deeply, without midnight wake-ups.

👉 This is the path to reclaim your biology and rewrite your story.

"During menopause, I was struggling with mood swings, fatigue, and a range of vague symptoms I couldn’t get a handle on. At Ellen Nijman, I discovered how much of a difference nutrition and stabilizing my blood sugar levels could make for my hormonal balance. With her targeted guidance and clear advice, I noticed my symptoms easing and felt noticeably more energized, and could sleep better.  She explained everything in a way that was both practical and empowering, which really helped me stay committed to the process."

"I have always found the consultations with Ellen to be pleasant; her expertise and empathy have given me, especially after my cardiac arrest, the revitalization and extra inner peace I needed."

"I was at my wit’s end with my health and had already tried so many things. Through Google I found Ellen, and from our very first phone call I finally felt heard and understood. She immediately saw what was going on and gave clear, calm guidance. The treatment itself was incredibly pleasant. Ellen works with expertise, dedication, and a truly personal approach. She takes her time, gets to the core, and intuitively knows what is needed. That gave me both trust and results: since then I’ve felt stronger and healthier. Our conversations have also left a lasting impression. The personal connection and her genuine care truly made a difference."

"After the birth of my baby, I was completely exhausted. The broken nights, constant alertness, and lack of deep rest were overwhelming. Ellen Nijman gave me  exactly the support I needed. She guided me with carefully selected supplements that are safe while breastfeeding, which helped me make the most of the sleep I could get and improved the quality of my rest. Thanks to her knowledge and reassuring approach, I feel clearer, stronger, and more emotionally balanced. I’m so grateful to have navigated this intense early phase of motherhood with more energy and stability."

"During an extremely difficult period, after the loss of my father and while my son was seriously ill, Ellen Nijman supported me in an incredible way. Her deep understanding of neurotransmitters helped rebalance my dopamine and serotonin levels, which was exactly what I needed to maintain my emotional and physical strength. Her guidance gave me calm, stability, and the energy to be there for my family. From the very beginning, I felt completely seen, understood, and safe thanks to her professional approach. Looking back, the orthomolecular treatment she provided had a profound impact on my resilience. I am deeply grateful for her transformative support."
