Is It Just the Texas Heat… or Is Your Nervous System Talking?

After living in Norway for the past three years, and in Northern Europe for nearly fifteen years before that, I knew coming back to Texas was going to be an adjustment. I remembered the Texas heat, but after so many years away, I had forgotten just how intense it could be.

As the temperatures climbed and the humidity settled in, I noticed something happening. I became more sedentary. More sluggish. My motivation dropped. Even simple tasks seemed to take more effort than usual.

I honestly thought it was just me.

I assumed my body simply needed time to adjust to being back in Texas. I kept telling myself to push through it and that eventually I would acclimate.

But it turns out it wasn’t just me.

The heat really was affecting my body.

And then I learned something fascinating.

Our brains are designed to keep us alive. When the temperature rises, the brain has to work much harder behind the scenes to keep everything in balance. It is constantly regulating our body temperature, heart rate, hydration, blood pressure, and electrolyte balance. Even if we are sitting comfortably in the air conditioning, our bodies are working overtime to maintain that balance.

I realized I wasn’t just uncomfortable. I was moving slower, thinking slower, and honestly, I just didn’t feel like myself.

Then I discovered something else.

Most of us think dehydration simply causes thirst, especially during a Texas summer. But even mild dehydration can affect concentration, memory, mood, and energy levels. Considering that the brain is made up of nearly 75 percent water, it doesn’t take much fluid loss before we begin to notice changes in how we think and feel. [Zhang N, Du SM, Zhang JF, Ma GS. Effects of Dehydration and Rehydration on Cognitive Performance and Mood Among Adults. Nutrients. 2019.]

As if that weren’t enough, July in Texas brings its own unique challenges. Warmer nights, longer daylight hours, disrupted routines, vacations, children home from school, and often…less sleep.

Summer is supposed to be a season of renewal. Yet when we aren’t sleeping well, our bodies lose the opportunity to repair and restore themselves. Sleep is when our brains process information, regulate emotions, strengthen memory, and prepare us for another day. When sleep suffers, everything else often follows. [Walker MP. Why We Sleep: Unlocking the Power of Sleep and Dreams.]

Another interesting fact about Texas summers is that prolonged heat places additional demands on our body’s stress response. Research has shown that extended heat exposure can be associated with increased cortisol, our primary stress hormone. When cortisol remains elevated for too long, we may begin noticing anxiety, irritability, brain fog, difficulty concentrating, and a greater sense of feeling overwhelmed.

Learning all of this completely changed my perspective.

I stopped blaming myself for feeling sluggish.

The heat really is asking more of my body than I realized.

Instead of believing I simply needed to survive another Texas summer until I “got used to it,” I began appreciating just how hard my nervous system was working every single day.

I can’t control the Texas weather.

I can’t make the humidity disappear.

I can’t eliminate every stressor that summer brings.

But I can support my nervous system while it works overtime.

That is one of the reasons IASIS Micro Current Neurofeedback has become such an important part of my own wellness journey. It isn’t trying to force the brain to relax or override what the nervous system is experiencing. Instead, it gives the brain an opportunity to recognize patterns that are no longer serving it and naturally reorganize toward greater balance.

When the brain becomes more adaptable, many people notice improvements in resilience, mental clarity, sleep, emotional regulation, and their ability to handle life’s everyday stressors. When the brain is balanced, everything else simply works better.

So before you tell yourself,

“I’m just cranky because it’s hot,”

Ask yourself a different question.

Sometimes what we dismiss as “just summer” is actually our brain reminding us that it has been carrying more than we realize.

This July, instead of simply surviving another Texas summer, maybe it’s time to work with your nervous system instead of against it.

Your brain is doing an incredible job protecting you.

Sometimes it simply needs a little support in return.

The goal isn’t to eliminate every stressor in life. That’s impossible. The goal is to help your nervous system become more adaptable, so it can respond to life’s challenges without becoming overwhelmed.
