Why sensitivity, hypervigilance and people-pleasing are often childhood trauma responses

Have you ever been told you're"too sensitive", or find yourself able to pick up on subtle changes in the room or a person's facial expressions and body language? This heightened awareness may feel like a personality trait, but more often than not, they are protective adaptations from unsafe environments.

In this article, we’ll explore how sensitivity and hypervigilance are not flaws, but intelligent responses formed in unsafe or unpredictable environments.

What is hypervigilance?

Hypervigilance is a state of heightened alertness where your nervous system is constantly scanning for threats - real or perceived. You may notice things others don’t, feel overwhelmed in crowds or noisy environments, or struggle to relax because your body is in chronic fight-or-flight mode. It is often experienced by those with PTSD or other trauma-related conditions.

This isn’t simply overthinking or anxiety, it’s your brain and body remaining prepared for danger, often because they’ve learned from the past that being relaxed wasn’t safe, that it always had to be 'on' to protect you.

The origins: trauma and the nervous system

When we experience trauma, particularly during childhood, our nervous system adapts to help us survive. If you grew up in an environment that was emotionally volatile, unpredictable, or unsafe, staying on guard became necessary.

Learning to anticipate moods or walk on eggshells because that vigilance helped prevent explosions, punishments, or emotional withdrawal became a survival mechanism.

Sensitivity as a survival strategy

Sensitivity, often mislabelled as weakness, is actually a sign of a finely-tuned nervous system. When your emotional or physical safety depended on your ability to detect subtle changes in others, feeling deeply and noticing everything was the adaptive response.

You might:

• Get overstimulated easily

• Feel overwhelmed by others’ emotions or environments that have a lot going on

• Struggle with criticism, perceived rejection, or change

The role of people pleasing: keeping the peace

People-pleasing is another trauma response that often goes hand-in-hand with hypervigilance and sensitivity.

When love, acceptance, or even basic safety was conditional on being good, helpful, or easy to be around, you likely learned to make yourself small. You tuned into others’ needs while disconnecting from your own, not because you were weak, but because it reduced conflict, rejection, or emotional abandonment.

People-pleasing can look like:

• Saying yes when you want to say no

• Avoiding conflict at all costs

• Apologising excessively

• Taking responsibility for others’ feelings

• Basing your worth on how needed or liked you are

At its core, people-pleasing is about survival, with the belief that "If I can keep everyone happy, maybe I’ll stay safe."

But as an adult, this strategy can leave you feeling resentful, invisible, and disconnected from your own needs and truth.

Integration

The tricky thing about these patterns is that they’re often unconscious. Your body continues operating as if it’s still in the original environment, even decades later.

With the right support and tools, you can begin to shift:

• From people-pleasing to boundary-setting

• From hypervigilance to grounded presence

• From sensitivity as a burden to sensitivity as a gift

This healing often involves:

• Nervous system regulation (somatic therapies, mindfulness practices)

• Inner child work and reparenting

• Building tolerance for saying no, disappointing others, or being seen in honouring your needs

• Therapeutic support that feels emotionally safe

Younger me

My story

I grew up in an emotionally abusive and neglectful household, with a volatile bipolar mother and a distant father. I was constantly criticised and belittled, walking on eggshells, not knowing what would set off my Mom's screaming tantrums from something as minor as my phone running out of battery. I tiptoed through childhood in a chronic state of fear, fight-or-flight and people pleasing, hoping it would keep her from exploding. I was an expert in gauging her moods at the expense of putting my needs last. This set me up for decades of people pleasing and perfectionism, with a shaky sense of self-belief. I carried an intense fear of confrontation, lived in hypervigilance, and silenced my own needs. Even now, these patterns still rise to the surface from time to time.

I have healed a lot of that through ongoing therapy, meditation, self-awareness and EMDR. Addressing these dynamics is what allowed me to show up with an embodied sensitivity, empathy and attunement in this line of work.
