PART 1 — What actually is autonomic nervous system dysregulation?
This is a big topic… but honestly, I think more people are struggling with nervous system dysregulation than they realise but they just don’t know that’s what’s happening.
People often say to me:
“I feel wired all the time.”
“I can’t switch off.”
“I’m exhausted but can’t relax.”
“My body feels constantly tense.”
“I feel overwhelmed by small things.”
“I crash after doing too much.”
And often, that can point towards a dysregulated autonomic nervous system.
Your autonomic nervous system is essentially your body’s automatic control system.
It regulates things you don’t consciously think about:
• Heart rate
• Breathing
• Digestion
• Blood pressure
• Stress responses
• Muscle tension
• Sleep
• Energy production
It has different “modes”.
One side gears you up for action and survival:
Fight.
Flight.
Stress.
Alertness.
The other helps you rest, recover, digest, heal, and feel safe.
The problem is that many people get stuck in survival mode for long periods of time.
Modern life doesn’t help:
• Chronic stress
• Poor sleep
• Trauma
• Burnout
• Illness
• Chronic pain
• Overtraining
• Emotional overload
• Viral infections
• Constant stimulation and screen time
Over time, the body can become hypersensitive and overprotective.
And eventually the nervous system stops responding appropriately to stress—it starts reacting to everything as if it’s a threat.
That can create very real physical symptoms:
• Tight muscles
• Fatigue
• Anxiety
• Digestive issues
• Dizziness
• Palpitations
• Poor temperature regulation
• Brain fog
• Pain flare-ups
• Feeling “on edge” constantly
This does NOT mean symptoms are “all in your head”.
The symptoms are very real.
But the nervous system itself may be struggling to regulate properly.
And the important thing to remember is this:
A dysregulated nervous system is not a broken nervous system.
It’s an overloaded, overprotective one.
And with the right support, pacing, awareness, and regulation work, many people can improve significantly over time.
Part 2 tomorrow:
“What causes nervous system dysregulation… and why is it often multifactorial?”
