Why Did I Get Cancer? with Deborah Herlax Enos

149. Can Complaining Change Your Brain?


Listen Later

Want to hear about the offbeat New Year’s resolution I cooked up?

My husband and I made a pact to stop grumbling, ditch negativity and silence our murmurs.

You might be thinking, “But you always seem so upbeat!” The truth is, like everyone else, I have my off days. My husband and I slipped into the trap of letting negativity take over our conversations.

We found ourselves griping about everything from the rain to the news to the traffic. Suddenly, our evenings felt like full-blown complaint parties.

Once we noticed this habit was stealing our joy and affecting our health, we knew it was time to make a change.

It hasn’t exactly been easy, but now our conversations feel lighter and more playful. Our evenings seem brighter and we’re both sleeping better than ever.

Digging into the research on negative conversations, I was stunned to learn just how much this habit can reshape your brain and not in a good way.

Want to break the habit too? Try the tips below and let me know how it goes!

1. Your Brain Gets “Wired” for Negativity

When you frequently complain or focus on negative thoughts, the brain strengthens those neural pathways.

  • The brain uses neuroplasticity, meaning it strengthens circuits that are used often.
  • Repeated negative thinking trains the brain to default to criticism, worry and dissatisfaction.
  • It’s like walking the same trail in the woods again and again. The more you use it, the clearer and easier that path becomes.

    2. Stress Hormones Stay Elevated

    Frequent negativity can trigger the body’s stress response.

    Key effects include:

    • Increased cortisol (the stress hormone)
    • Activation of the fight-or-flight response
    • Increased inflammation in the body
    • Chronically elevated stress hormones are linked to:

      • Weight gain (especially belly fat)
      • Sleep problem
      • Weakened immune system
      • 3. Your Brain’s Memory and Learning Can Decline

        Chronic negativity and stress can affect the hippocampus, an important brain area involved in memory and learning.

        High stress and cortisol over time may:

        • Reduce new neuron growth
        • Impair memory
        • Make concentration harder
        • To break free from this cycle, try focusing on solutions or weaving gratitude into your daily routine. Even small shifts like these can help your brain lean toward the positive.

          I knew little about copper peptides until I heard Vitali founder Debbi Barber on a podcast. She was talking about the power of copper peptides to help reduce the appearance of scars.

          Since I have plenty of scars, I thought I’d give it a try.

          I used the GHK-Cu Serum on my scars and my face. Within days, the skin on my face became so much softer! And after a few months of use, my skin felt thicker and smoother. Bonus that my mastectomy scars also started to lighten!
