Cortisol, Perimenopause, and Midlife: When “Healthy” Habits Create More Stress

One thing I mention often on the podcast is cortisol. I’ll casually say something like, “That could be raising your cortisol,” or “This might not be helping during perimenopause.” But I realized recently that I’ve never really sat down and explained what cortisol is, why it matters so much in midlife, and how everyday habits: yes, even healthy ones, can quietly push it too high.

So today, we’re diving in.

What Is Cortisol and Why Does It Matter More in Midlife?

Cortisol is often called the stress hormone, but that doesn’t mean it’s bad. In fact, cortisol is essential. It helps you wake up in the morning, respond to challenges, regulate blood sugar, and cope with stress.

The issue isn’t cortisol itself; it’s too much cortisol for too long.

During perimenopause, estrogen and progesterone begin to decline. Progesterone, in particular, has a calming effect on the nervous system. When progesterone drops, cortisol often rises to compensate. That shift alone can make your body feel more reactive, more inflamed, and less resilient than it did just a few years ago.

This is why so many women in midlife experience:

  • Weight gain (especially around the middle)
  • Fatigue
  • Poor sleep
  • Mood swings
  • Feeling “wired but tired”

And often, it’s not because you’re doing something wrong; it’s because you’re doing too much of the right thing.

Everyday Things That Can Raise Cortisol Levels

This is where things get interesting. Many cortisol triggers are things we’ve been told are “healthy” or “normal.”

Here’s a list of common cortisol boosters to reflect on, not judge yourself for.

Nutrition & Stimulants

  • High sugar foods and drinks
  • Refined flour and processed foods
  • Alcohol
  • Excess caffeine
  • Skipping meals (including intermittent fasting when your body isn’t ready)

Skipping meals is a big one. Even unintentionally missing lunch while working can register as stress to your body and trigger cortisol release.

Exercise & Physical Stress

  • Too many high-intensity workouts
  • Chronic pain or ongoing discomfort
  • Hot and cold therapies (yes, even those)

High-intensity workouts can be helpful but in midlife, more is not better. For many women 45+, one to two high-intensity sessions per week is plenty.

Lifestyle Stressors

  • Poor sleep or sleep deprivation
  • Staying up late, even if you still get 7–8 hours
  • Long daily commutes
  • Chronic mental stress
  • Poor posture (slumped shoulders signal stress to the nervous system)

Hormonal & Chemical Factors

  • Corticosteroids (like cortisone)
  • Estrogen dominance (common before estrogen begins to decline)
  • Smoking, marijuana use, or recreational drug use
  • Excess sodium (especially from processed foods)
  • High omega-6 intake from seed oils

Nutrient Deficiencies

Low levels of certain nutrients can also raise cortisol, including:

  • Magnesium
  • Zinc
  • Vitamin A
  • Potassium

This is one of the many reasons I emphasize variety in fruits and vegetables. When you rotate foods over weeks and seasons, you naturally cover these bases without overthinking it.

The Goal Isn’t to Eliminate Cortisol—It’s to Reduce the Pile-Up

This is important, so I want to say it clearly:

👉 The goal is not to remove every cortisol trigger from your life.

Cortisol is necessary. The problem is when your body is hit with stress responses all day long, every day, without enough recovery.

If you look at this list and can check off 10 or more items, that’s a sign your nervous system may be overloaded, not broken, just overwhelmed.

And no, this doesn’t mean “take away everything fun.”

It means reframing pleasure.

Listening to Your Body (Instead of Fighting It)

I used to love staying up late, going out to dinner, having a glass of wine with friends. Over time, I noticed those things didn’t feel as good anymore.

So I didn’t punish myself; I adjusted.

Now, pleasure looks like:

  • Reading a book in the evening
  • Drinking hot tea
  • Going to bed earlier
  • Waking up feeling rested instead of drained

That’s the work in midlife: noticing what actually makes you feel better now, not what used to.

And this will look different for everyone.

For example, cold therapy doesn’t bother me even though it can raise cortisol for some women in perimenopause. My body handles it just fine. Yours might not. The key is paying attention to how you feel afterward.

Do you feel calm? Or jittery and anxious? That answer matters more than any rule.

Gentle Ways to Lower Cortisol Naturally

You’ve heard these before, but that’s because they work:

  • Prioritize consistent, quality sleep
  • Move your body regularly (without overdoing it)
  • Practice slow, calming breathing
  • Laugh and spend time with people who lift you up
  • Maintain supportive relationships
  • Hug someone you love (30–45 seconds can reduce cortisol)
  • Spend time with pets
  • Practice simple self-care

None of this needs to be extreme. Small shifts create big changes when your nervous system is involved.

Start Small—and Notice How You Feel

Instead of changing everything, choose one or two things to adjust. Then notice:

  • How you sleep
  • How your energy feels
  • How your mood responds

Midlife isn’t about pushing harder it’s about responding smarter.
