Your brain is not a democracy.
It’s a hormone dictatorship.

Most decisions people think are “willpower,” “discipline,” or “personality” are actually driven by hormones like dopamine, cortisol, insulin, thyroid hormones, oxytocin, and testosterone.

These systems control:
• motivation
• attraction
• stress tolerance
• burnout
• bonding
• energy
• behavior

When hormones are dysregulated, behavior changes.
Not because you’re failing. Biology is just responding to stress, fuel, and connection.

This is the foundation of Hijacked: understanding how hormones quietly run your life so you can stop blaming yourself and start working with your biology instead of against it.

If this made you pause, the full breakdown is on my Substack. Comment READ and I’ll send you the article.

You’ve done all the therapy and still keep choosing the same person, even when you know better?

You don’t have a “type” or keep “self- sabotaging”.

It’s biology.

Attraction isn’t rational. It’s driven by dopamine, cortisol, and oxytocin.
The same systems that regulate reward, stress, and bonding.

Dopamine makes unpredictability feel exciting.
Cortisol makes familiar chaos feel safe.
Oxytocin bonds you before logic can vet compatibility.

That’s how stress gets mislabeled as attraction.
And why calm can feel boring.

You’re not broken. Your body is running old code (yes, I think of it like a computer).
The good news is code can be rewritten.

Does this make sense?

Save this post to reference back to.

Most women don’t realize how easy it is for estrogen to bottom out.

Stress, under-eating, poor sleep, extreme dieting, and gut issues all impact how your body makes and converts estrogen.

Here are the basics:

Understand where estrogen comes from (ovaries, adrenals, and body fat), then support those pathways with strength training, enough calories, healthy fats, fiber, protein, gut support, and real stress management.

You do not have to accept low energy, low libido, mood swings, or irregular cycles as your new normal.

When you support the inputs, your hormones respond.

If you want more help balancing hormones, lowering stress, and actually feeling like yourself again, follow along or dive into my Substack.

I hate talking about dating psychology because, full honesty, I was NOT good at dating, and I’m not a relationship expert.

But I am a hormone expert.

And once I started studying attraction, cortisol patterns, birth control, dopamine cycles, and nervous system responses… everything finally made sense in a way psychology never did.

Most people don’t attract emotionally unavailable partners because of their “type.”

It usually comes down to biology, burnout, stress hormones, and dopamine patterns that trick the brain into labeling anxiety as chemistry.

🧪 High cortisol makes unpredictability feel exciting.
🧪Birth control can alter who you’re attracted to.
🧪Dopamine burnout makes stable people seem “boring.”
🧪Low testosterone and chronic stress shut down emotional availability in men.

Once you understand the biology, the pattern stops feeling personal, and starts feeling fixable.

I’m Causey, the reluctant dating commentator who can’t help but explain the hormone science behind your love life.

Am I right moms?

Dating isn’t harder because everyone suddenly got “too picky.”
It’s harder because our biology hasn’t caught up to dating apps.

Men are dating with 40% lower testosterone than a generation ago.
Women are dating with burnout, birth control–altered attraction, and a nervous system that is DONE with mediocre men.

Add in dopamine-driven swiping, infinite options, comparison culture, and delusional algorithms… and yeah, modern dating feels biologically rigged.

Your brain was built for slow-burn chemistry. Not slot-machine dopamine hits.

My suggestion? Build actual connection offline. Take a chance on someone you maybe wouldn’t otherwise. I’m not asking you to marry them, I’m telling you to get to KNOW them. Your hormones might thank you.

P.S. This isn’t something I usually talk about. As someone who hasn’t dated in years, I don’t really feel “qualified” to. But I did write a few articles on the hormonal science of dating in Substack if anyone wants a deeper dive. Just comment “Substack” and I’ll send you the link.

Mom brain at its finest!

Of course the disappearing ink pen would look exactly like my regular every day pen. Otherwise I what’s the fun in that?

Needless to say, some semi-important things may be forgotten 🤷🏼‍♀️

The first time my family asked me to host Thanksgiving I served salmon and asparagus.

I have not been asked again.

That was 2005.

My friends have learned my style as well.

Cravings are not a weakness or personality flaw.

They are clear signals from hormones, minerals, and the nervous system.

🍩Sugar cravings appear when glucose drops.
🧂Salt cravings appear when cortisol or minerals are low.
🥜Crunch cravings appear when the nervous system needs stimulation.
🧊Ice cravings point to low iron.
😖PMS cravings come from shifts in progesterone and serotonin.

Strong cravings often appear when you under-eat earlier in the day.

Your body communicates constantly.
The more you listen, the better you feel.

💬 Save this for the next time cravings hit.
