The Brain on Cortisol

Long before you realize the problem, your brain may be wired to fail in ways that might surprise you. How so?

Let’s say you find yourself crankier than normal.  You may suffer anxiety, or fear taking that risk that will move you forward at work. When this happens, you’ve likely stirred up a chemical hormone in your brain that pushes against relationships, courage, solutions, and general well being.

Cortisol is a potent chemical that surges when you slip into stress, and is now  recognized  as a drug that can literally shrink human brains.  It leaves other damaging footprints behind too, that luckily can be avoided through awareness of its trickery. Researchers have known for some time, for instance,  that cortisol shuts down learning, creates anxiety attacks and can cause depression.

Less known, until recently, are tactics to counter cortisol surges.

You may be saying … but cortisol has useful purposes, and you are correct. It’s a short term chemical which is useful to treat allergies, or zap you with the energy to survive a shocking moment. Cortisol can also lower sensitivity to pain, help you to survive grief, or pull you through a short term pressure project.

Long-term cortisol surges though, where you maintain harmful levels,  can be highly dangerous. Research shows cortisol to:

1. Lower immune systems
2. Slow down thinking
3. Create blood sugar imbalances
4. Raise your blood pressure
5. Weaken muscle tissue
6. Decrease bone density
7. Increase fat to stomach areas.

Can you see why you may react negatively when under the influence of harmful chemical surges?

To flee from and lower dangerous levels of cortisol:

a. Relax, listen to music,  take a walk, and run from stress.
b. Spend time with upbeat people, laugh, and steer away from cynics.
c. Manage time, create  doable daily targets, and avoid overloads
d. Take up a sport, do stairs, park far from doors and avoid passivity.
e. Give away things, care, join Rotary, and run from financial anxiety.
f. Teach from your strengths, inspire excellence, yet flee perfectionism.
g. Propose winning solutions and avoid fixation on problems at work.

You get the idea, and will likely have better alternatives than mine, to sidestep cortisol’s confinement. Strange as it may seem, the key is to do the opposite of whatever creates cortisol. To do the opposite of a cortisol response, is to rewire the brain for more serotonin guided behaviours.

Luckily the human brain also comes fine tuned for serotonin success, through doing healthier actions.  For example, your brain will rewire dendrite brain cells for serotonin well-being and growth plasticity in areas that had once created cortisol imbalances.

It’s worth an effort to make a few changes, when you think about the rewards. People who do so, tend to replace cortisol crankiness for serotonin serenity. It’s also true that some people come with lower levels of this drug, or seem to generate fewer fluctuating cortisol surges.  Have you noticed how calm and rational some people are - even if a hairy spider meanders past?

Spiders aside,  did you know that at least 22 stressors will creep in on you - even on an ordinary day.

    Wow, Ellen! What a wonderful post! Through your great advice, you’ve armed us with the knowledge we need to take charge of our cortisol-induced catastrophes and turn them into serotonin-fueled successes.

    Thanks for these immensely practical techniques!

    Jeanne, can you imagine that we actually have choices here that we had no idea we owned (or at least i did not). It still takes stepping back - in my case - when I hit a situation that I may respond in cortisol — unless I roll it back and wait for the serotonin flow.

    Oh, how wonderful it is to remember serotonin’s help ahead, and not to have to go back and try to repair:-) Either way - it’s usually worth knowing and trying to use more serotonin for mental fuels:-).

    Imagine what that would do for teens in secondary schools, for business leaders who feel frazzled, or for people who think they are too old to catch the coming waves:-).

    Choices! What a novel idea! So often we forget that we have choices when we’re faced with unpleasant situations. We feel as if we must respond negatively to negative stimuli. But, that simply isn’t true!

    It’s so important to remember that the way we react to a given situation is entirely up to us, and that gives us great freedom and an amazing degree of control over our circumstances. Even when it doesn’t change our circumstances, it changes us — from the uptight reactor to the calm, collected proactor. It’s a great deal, all around!

    And just knowing that all we have to do to initiate the flow of serotonin is choose not to fall into the negativity trap is not just liberating but motivating, too! If everyone realized — and practiced — this, just think how amazing our schools and workplaces (not to mention all other places) would be!
