Your Reticular Activating System: Why Your Brain Notices What You Focus On

Wendy Francis, NBC-HWC – Board-Certified Health Coach and Functional Nutritionist

Have you ever bought a new car and suddenly started seeing that exact car everywhere?

Or maybe someone mentions a word, a health condition, or even a life goal... and now it feels like it is showing up constantly around you.

That is not magic.

That is your brain doing exactly what it was designed to do.

It is called the Reticular Activating System, also known as the RAS, and understanding it can completely change the way you approach your health, habits, mindset, and even your future.

So What Is the Reticular Activating System?

Your Reticular Activating System is basically your brain’s filtering system.

Every second, your brain is being bombarded with massive amounts of information:

  • Sounds
  • Conversations
  • Thoughts
  • Emotions
  • Visual information
  • Stress signals
  • Memories
  • Environmental cues

If your brain paid attention to every single thing equally, you would feel completely overwhelmed.

So your RAS decides what is important enough to bring to your attention.

In simple terms:

Your brain finds evidence for whatever you repeatedly focus on.

Why This Matters for Your Health

This is where things get really interesting.

If someone constantly tells themselves:

  • "I always fail"
  • "I can never stay motivated"
  • "I’m too tired"
  • "Nothing ever works for me"

The brain starts filtering life through that lens.

The RAS begins collecting proof to reinforce those beliefs.

On the other hand, when someone starts intentionally focusing on growth, healing, possibility, and consistency, the brain starts noticing opportunities, solutions, and progress that may have been ignored before.

This is one reason why mindset work is not fluff.

It is neuroscience.

Your Brain Loves Familiarity

One thing I explain to clients all the time is this:

Your brain’s number one job is not happiness.

It is survival and familiarity.

Even unhealthy habits can feel “safe” to the brain simply because they are familiar.

That means your brain may actually resist positive change at first.

Not because you are lazy or broken.

But because your brain is trying to keep you in patterns it recognizes.

This is exactly why creating new habits can initially feel uncomfortable.

The good news is that the brain is adaptable.

Through neuroplasticity, your brain can literally begin forming stronger pathways around healthier thoughts, behaviors, and routines over time.

How to Start Training Your RAS

The beautiful thing about the Reticular Activating System is that you can begin influencing it intentionally.

Here are a few simple ways:

1. Pay Attention to Your Self-Talk

Your brain is always listening.

Constant negative self-talk becomes programming.

Start replacing “I can’t” with:

  • “I’m learning”
  • “I’m improving”
  • “I’m becoming healthier”
  • “I’m capable of change”

2. Visualize What You Want

Your brain responds strongly to repetition and imagery.

This is why athletes use visualization constantly.

The more clearly you visualize a healthier version of yourself, the more your brain begins looking for ways to align with that identity.

3. Change What You Feed Your Brain

Your environment matters.

The conversations you listen to, the content you consume, the people around you, and even the words you repeatedly hear all influence your RAS.

Your brain starts normalizing whatever it is exposed to most often.

4. Focus on Small Wins

Many people overlook progress because they are only focused on massive transformations.

But your brain responds incredibly well to evidence of success.

Small wins help build momentum and reinforce new neural pathways.

This Is a Big Part of What I Do as a Health Coach

A lot of people think health coaching is simply about food and exercise.

But honestly, so much of what I do involves helping people retrain the way their brain approaches health, stress, habits, confidence, and change itself.

Because if the brain is not on board, lasting change becomes much harder.

I work with clients on creating awareness around thought patterns, stress responses, behavior loops, and the subconscious programming that may be keeping them stuck.

Once people understand how their brain works, everything starts making a lot more sense.

And that is where real transformation can begin.
