Signs Your Nervous System Is Stuck in Survival Mode

August 02, 2026•7 min read

Some of the women I work with describe it as feeling "tired but wired." Others describe a kind of flatness - going through the motions, disconnected from their own life. Both are describing the same underlying problem from two different angles: a nervous system that's stuck in survival mode.

This isn't about being dramatic or "not managing stress well." It's a physiological state with a name, a mechanism, and - importantly - a way out.

A Quick Primer: Your Nervous System Has Three Gears, Not Two

For a long time, the nervous system was described simply: "fight or flight" (sympathetic) versus "rest and digest" (parasympathetic). Polyvagal theory, developed by Dr. Stephen Porges, added an essential third gear.

  • Ventral vagal state - you feel safe, socially engaged, calm, and able to think clearly.

  • Sympathetic state - fight or flight. Heart rate up, muscles ready, mind racing, scanning for threat.

  • Dorsal vagal state - freeze or shutdown. When fight or flight isn't possible, the body conserves energy by going numb, foggy, or immobilised.

Under healthy conditions, you move fluidly between these states depending on what's happening around you. The problem starts when your nervous system gets stuck in the sympathetic or dorsal vagal gear, unable to find its way back to a calm, regulated ventral state — even when there's no actual danger present.

Signs You're Stuck in the "Fight or Flight" Gear

  • Feeling wired and unable to switch off, even at bedtime

  • A racing or intrusive mind that jumps from worry to worry

  • Irritability or a short fuse over small things

  • A chronically tight jaw, shoulders, or chest

  • Difficulty sitting still or relaxing without feeling guilty or anxious

  • Catastrophising or expecting the worst-case outcome by default

This state evolved to help you respond to a genuine, short-term threat. The problem is when it stays switched on for weeks, months, or years — chronically activated fight-or-flight is strongly linked to ongoing anxiety, fatigue, and broader health problems.

Signs You're Stuck in the "Freeze or Shutdown" Gear

This state is less talked about, but just as common — especially in women who have been "coping" for a long time.

  • Persistent fatigue that sleep doesn't fix

  • Feeling foggy, numb, or disconnected from your own emotions

  • Withdrawing from people you usually enjoy being around

  • Struggling to get motivated even for things you care about

  • A sense of watching your own life from a slight distance

  • Physical heaviness or a sense of being "shut down"

Dorsal vagal shutdown is understood as the body's last-resort survival strategy - when fighting or fleeing isn't possible or hasn't worked, the system conserves energy by minimising activity altogether. It's protective in the short term, but exhausting and isolating when it becomes your default state.

Why This Happens More After 35

Several things compound during this life stage:

  • Accumulated, unresolved stress from years of juggling work, caregiving, and relationships

  • Hormonal shifts in perimenopause, which affect how resilient your stress response naturally is

  • Poor sleep, which prevents the nervous system from getting its nightly "off switch"

  • Blood sugar instability, which directly triggers a stress-hormone response (more on this in Can Blood Sugar Cause Panic Attacks?)

None of this means something is broken in you. It means your nervous system has been asked to do a lot, for a long time, without enough deliberate "off-ramps."

Neuroception: Why Your Body Reacts Before You Decide To

A key concept in polyvagal theory is neuroception - your nervous system's unconscious, constant scanning for cues of safety or danger, happening well below the level of conscious thought. This is why you can't simply "decide" to feel calm in a stressful moment. Your body has often already responded, via neuroception, before your thinking brain even registers what happened.

This matters because it reframes what regulation actually requires. It's not about controlling your thoughts through willpower alone - it's about giving your body enough repeated, reliable cues of safety that its automatic scanning system gradually recalibrates toward a calmer baseline. This is a slower, more physiological process than most people expect, which is exactly why consistent small practices tend to outperform occasional big efforts.

How to Start Shifting Out of Survival Mode

The nervous system responds to cues of safety - simple, repeatable signals that tell your body it's okay to stand down. These aren't about ignoring real problems; they're about giving your physiology permission to recalibrate.

  • Extend your exhale. A longer out-breath than in-breath activates your vagus nerve and signals safety - try inhaling for 4 counts and exhaling for 6-8.

  • Try humming, singing, or gentle chanting. The vibration directly stimulates the vagus nerve.

  • Use brief cold exposure, like splashing cool water on your face, to interrupt acute overwhelm via the dive reflex.

  • Build in micro-moments of genuine rest across the day, not just at bedtime - even 90 seconds counts.

  • Prioritise safe social connection. Co-regulation with a trusted person is one of the fastest ways back to a calm state.

  • Incorporate light therapy into your day to day activities – more information shared here

  • Support the physical layer too - stable blood sugar and good sleep make emotional regulation strategies far more effective.

Moving Between States: What Regulation Actually Looks Like

It's worth being clear that the goal isn't to live permanently in a calm, ventral vagal state - that's not realistic or even desirable, since sympathetic activation is genuinely useful for meeting real demands, like a deadline or a physical challenge. The goal is flexibility: being able to move into fight-or-flight when it's useful, and then reliably move back to a calm, regulated state once the demand has passed.

A dysregulated nervous system isn't one that occasionally gets activated - every nervous system does that. It's one that struggles to come back down afterwards, or one that skips straight to shutdown because fight-or-flight has stopped feeling like a viable option. Recognising which pattern is more true for you is genuinely useful information, because the "off-ramps" that help are slightly different depending on which gear you tend to get stuck in.

If You Tend to Get Stuck in Fight-or-Flight

Focus on inputs that actively down-regulate: longer exhales, cold water on the face, gentle movement to discharge built-up energy, and reducing stimulants like caffeine later in the day.

If You Tend to Get Stuck in Freeze or Shutdown

Focus on inputs that gently activate rather than further calm: light movement, upbeat music, safe social connection, and short bursts of energising activity — approached gradually, since pushing too hard, too fast can sometimes tip back into overwhelm.

This Is a Pattern, Not a Personality Trait

If you recognise yourself in this article, please hear this: being stuck in survival mode is not a flaw in your character or a sign you're "too sensitive." It's a nervous system doing exactly what it was designed to do, for longer than it was designed to do it. And it can shift — often faster than people expect, once the right small, repeated inputs are in place.

If dysregulation is linked to past trauma or feels severe or persistent, working with a trauma-informed therapist alongside these strategies can make a meaningful difference.

Frequently Asked Questions

How do I know if I'm in fight-or-flight or shutdown right now?

Fight-or-flight tends to feel active - racing thoughts, tension, restlessness, irritability. Shutdown tends to feel passive - numbness, fatigue, disconnection, low motivation. Some people move between both across a single day.

Is this the same thing as trauma?

Not necessarily. While chronic nervous system dysregulation is common after trauma, it can also develop from ordinary, sustained stress - years of overcommitment, poor sleep, or unaddressed anxiety, without any single traumatic event.

How long does it take to feel more regulated?

Many people notice small shifts within days of consistently practising simple regulation techniques like extended-exhale breathing, though rebuilding a more flexible, resilient baseline is usually a matter of weeks to months of consistent practice, not a single technique used once.
