Is Your Body Stuck in "Fight or Flight"?
Understanding Stress Beyond Your Mind
By Dr. Charlie Roach, D.Ac., L.Ac., FMP
Most people think of stress as something that happens in the mind.
A busy schedule.
Financial worries.
Relationship challenges.
Work deadlines.
While these certainly create stress, your body doesn't distinguish between emotional stress and physical stress. To your nervous system, stress is simply anything that requires adaptation.
At Root & Branch Acupuncture & Integrative Health, one of the most common patterns I see is a nervous system that has been working overtime for months—or even years.
The good news?
The nervous system can often become more resilient with the right support.
Your Nervous System Has Two Primary Modes
Think of your nervous system like the transmission in a vehicle.
Sympathetic Mode
Often called "fight or flight."
This state prepares you to:
Respond to danger
Increase heart rate
Raise blood pressure
Release glucose into the bloodstream
Sharpen focus
Increase cortisol production
This response is essential for survival.
The problem isn't entering this state.
The problem is never fully leaving it.
Parasympathetic Mode
Often called "rest and digest."
This is where healing occurs.
In this state your body can:
Digest food efficiently
Repair tissues
Strengthen immunity
Balance hormones
Build muscle
Restore energy
Many people spend far too little time here.
Modern Stress Looks Different
Thousands of years ago stress usually came from immediate threats.
Today it often comes from:
Constant notifications
Lack of sleep
Processed foods
Chronic inflammation
Financial pressure
Overtraining
Poor recovery
Environmental exposures
Chronic illness
Even though these stressors feel different, your body still responds with the same stress physiology.
Signs Your Body May Be Under Chronic Stress
You may notice:
Difficulty falling asleep
Waking during the night
Afternoon fatigue
Feeling "wired but tired"
Digestive problems
Muscle tension
Frequent headaches
Sugar cravings
Difficulty concentrating
Feeling overwhelmed by small problems
These symptoms don't necessarily mean there is a single underlying diagnosis, but they can suggest that your nervous system has been carrying a heavy load.
Cortisol Is Not the Enemy
Cortisol often gets a bad reputation.
In reality, cortisol is one of your body's most important hormones.
Healthy cortisol helps:
Maintain blood sugar
Control inflammation
Wake you up in the morning
Support normal immune function
Respond to physical challenges
The goal isn't to eliminate cortisol.
The goal is healthy regulation.
Like many things in biology, balance matters more than extremes.
Healing Requires Safety
One of the most overlooked concepts in health is this:
Your body heals best when it feels safe.
That doesn't simply mean emotional safety.
It also includes:
Eating enough protein
Sleeping consistently
Recovering from exercise
Spending time outdoors
Building healthy relationships
Breathing deeply
Taking time to slow down
These habits send powerful signals to your nervous system that resources are available and recovery is possible.
Small Daily Habits Matter
You don't need an elaborate morning routine to improve resilience.
Simple practices can make a meaningful difference over time.
Consider:
Getting outside within an hour of waking
Walking after meals
Practicing slow diaphragmatic breathing
Strength training several times per week
Eating regular, balanced meals
Limiting screen exposure before bed
Maintaining a consistent sleep schedule
These habits won't eliminate stress, but they can improve your body's ability to adapt.
A Functional Medicine Perspective
At Root & Branch, we recognize that chronic stress may influence many body systems, including digestion, hormones, immune function, and metabolism.
Rather than asking,
"How do we suppress this symptom?"
we ask,
"What is keeping this person's nervous system under constant demand?"
The answer is different for everyone.
Sometimes it's poor sleep.
Sometimes it's chronic inflammation.
Sometimes it's unresolved digestive issues.
Sometimes it's simply years of carrying too much.
Understanding those factors allows us to create a more personalized plan.
The Goal Isn't a Stress-Free Life
Stress is part of being human.
The goal isn't to remove every stressor.
The goal is to build a body that can respond to life's challenges and return to a state of balance.
Resilience—not perfection—is what supports long-term health.
Ready to Restore Balance?
If you've been feeling exhausted, overwhelmed, or like your body never truly relaxes, it may be time to look deeper.

Dr. Charlie's Perspective
One of the greatest lessons I've learned—both personally and professionally—is that health isn't about eliminating every challenge. It's about building a body that's capable of adapting to them.
When we support sleep, nourish ourselves well, move regularly, strengthen meaningful relationships, and spend time in nature, we're not just "being healthy." We're teaching our nervous system that it's safe to recover.
That is where lasting health begins.
