Regulating Through the Four Threats to the Nervous System (A Guide for Parents & Therapists)

A Synergetic Play Therapy Perspective

Our nervous systems are constantly scanning for safety and danger.

According to Synergetic Play Therapy (SPT), there are four primary threats or challenges the nervous system monitors in order to support survival. Our amygdala, the brain’s alarm system, is continuously asking:

“Am I safe?”

And because humans rely on both physical and emotional safety for survival, the nervous system responds not only to physical danger, but also to things like unpredictability, disconnection, shame, and incongruence.

The four primary nervous system threats include:

• Physical and emotional safety

• Perceptions of the unknown

• Incongruence in the environment

• “Shoulds” or unrealistic expectations

Understanding these threats can help us better understand ourselves, our children, and the behaviors that emerge when the nervous system perceives danger. It can also help us approach regulation from a place of compassion instead of judgment.

Physical & Emotional Safety

Our nervous system’s primary goal is survival.

The amygdala is constantly scanning the environment for cues of danger and cues of safety. Because humans are relational beings, safety is not only physical, it is emotional and relational as well.

Especially for children, emotional safety often includes:

• Feeling connected

• Feeling accepted

• Feeling understood

• Knowing emotions and needs can exist without shame or rejection

• Being able to show up authentically

Trauma and past experiences strongly shape how the nervous system interprets safety. This is why trauma reminders can feel so activating. Even when danger is no longer present, the nervous system may respond as if the threat is happening again in real time.

For individuals with rejection sensitivity, particularly many neurodivergent individuals, the nervous system may also have difficulty identifying cues of safety and instead stay highly attuned to possible criticism, exclusion, or disconnection.

Sometimes the nervous system is not asking:

“Am I physically safe?”

It’s asking:

“Am I emotionally safe to exist as myself here?”

Supporting Regulation Through Safety

When the nervous system perceives danger, grounding through the senses can help orient us back to the present moment and remind the body that we are safe here and now.

Some regulating supports might include:

• Playing “I Spy” and noticing what’s around you

• Finding all the red, blue, or yellow objects in a room (or doing the same thing on a mindfulness walk)

• Smelling strong scents like peppermint, citrus, or lavender

• Eating something sour, minty, crunchy, or spicy

• Wrapping up in a soft or weighted blanket

• Spending time with safe, attuned people (including pets)

• Setting boundaries with people or environments that feel unsafe

• Visualizing a safe place or a safe person

• Walking, stretching, dancing, shaking, or engaging in movement to help complete the stress cycle

• Using intentional breathing. For example, longer exhales can support fight-or-flight activation, and longer inhales can support shutdown or collapse states

Regulation is not about forcing calmness. It’s about helping the nervous system reconnect with safety.

Perceptions of the Unknown

Unknowns are not inherently dangerous, but our nervous system’s perception of them can feel threatening.

When we encounter uncertainty, the brain automatically searches the past for patterns and experiences to help predict what might happen next. If previous experiences involved fear, unpredictability, trauma, or instability, the nervous system may interpret new experiences through that lens.

This can also include intergenerational trauma, where fears and survival responses are passed down across generations.

For many people with anxiety, the nervous system tends to err on the side of caution. It often assumes danger first in an attempt to keep us safe.

Humans also have a negativity bias, meaning our brains remember threatening or painful experiences more easily than neutral ones because remembering danger historically increased survival.

Children encounter unknowns constantly:

• New people

• New environments

• New expectations

• New social situations

• New experiences

Unlike adults, they have fewer lived experiences and fewer “data points” to reassure their nervous systems that things will likely be okay.

Supporting Regulation Around Unknowns

One of the ways we support regulation is by helping make unknowns feel more known.

This might include:

• Creating predictable routines and structure

• Preparing children ahead of transitions or changes

• Answering questions openly and honestly

• Using visual schedules or countdowns

• Offering transition objects like stuffed animals, fidgets, or photos

• Encouraging curiosity instead of catastrophic thinking

• Reflecting on previous experiences of getting through uncertainty

• Thinking through what would realistically happen if fears came true, and what supports would still exist

Play therapy can also help children gradually expand their window of tolerance for uncertainty, unpredictability, and feeling out of control, which are common drivers of anxiety.

Because the goal is not to eliminate all unknowns from life. The goal is to help the nervous system learn that it can survive and move through them.

Incongruence in the Environment

Our nervous systems feel safest with predictability, consistency, and authenticity.

When things in the environment do not “match up,” the brain often experiences that as confusing, unpredictable, or unsafe. This is called incongruence.

Examples might include:

• Someone saying “I’m fine” while visibly upset

• Facial expressions not matching the emotional tone

• Tension in the home that no one acknowledges

• Big family changes that are avoided or kept secret

• Caregivers masking emotions to appear calm all the time

Children are incredibly perceptive. They often sense when something feels “off,” even when adults do not explicitly name it.

And when children feel something changing in the environment but no one helps them organize or understand the experience, the nervous system may remain stuck in uncertainty.

Adults sometimes feel pressure to appear calm, happy, or perfectly regulated around children at all times. But regulation is not about emotional perfection. Regulation is about congruence.

Children do not need adults who never feel or express hard emotions. They need adults who can experience emotions authentically and safely.

Supporting Regulation Through Congruence

Some ways we can support regulation include:

• Naming emotions honestly and appropriately

• Noticing and identifying body sensations

• Expressing feelings through talking, art, movement, journaling, or play

• Talking through difficult topics in developmentally appropriate ways

• Giving ourselves and children permission to show up authentically

• Increasing tolerance for emotions rather than immediately avoiding or suppressing them

Often, regulation is less about “staying calm” and more about allowing emotions to move through safely and authentically.

“Shoulds” & Unrealistic Expectations

Another major threat to the nervous system comes from internal incongruence, often experienced through “shoulds.” Shoulds are the expectations we place on ourselves, others, or the world.

Examples might sound like:

• “I should be more patient.”

• “I shouldn’t feel this way.”

• “Kids should know better.”

• “I should be able to handle this perfectly.”

When reality does not align with those expectations, the nervous system can become dysregulated.

Shoulds often disconnect us from our own intuition, emotions, body cues, and needs, because they prioritize performance over authenticity.

This is especially important to consider when working with or parenting children.

What expectations are we communicating, directly or indirectly?

Are they:

• Realistic?

• Developmentally appropriate?

• Neurodivergent-affirming?

• Rooted in connection rather than control?

Supporting Regulation Around “Shoulds” or Unrealistic Expectations

Some ways to reduce nervous system activation around unrealistic expectations include:

• Practicing self-compassion

• Noticing when “should” language appears

• Getting curious about where those expectations came from

• Talking to yourself the way you would speak to a child or loved one

• Allowing room for mistakes and repair

• Checking in with your body and emotions regularly

• Giving yourself what you actually need rather than what you think you should need

Children are constantly observing how adults relate to themselves. The way we speak to ourselves becomes part of the template children develop for their own inner voice.

And maybe one of the most regulating things we can model for children is not perfection. Maybe it’s showing up as authentic, self-aware humans who can:

Feel emotions

• Set boundaries

• Make mistakes

• Repair relationships

• Practice self-compassion

• Stay connected through difficult experiences

Because safety is not created through perfection. Safety is created through connection, authenticity, and nervous systems that feel safe enough to be human.

Final Note

If you’re noticing signs of anxiety, emotional overwhelm, perfectionism, sensory sensitivities, behavioral challenges, or nervous system dysregulation in your child, play therapy can help create a space for support, regulation, and healing. Through a neurodivergent-affirming and nervous-system-informed approach, children can build emotional awareness, resilience, self-compassion, and a greater sense of safety within themselves and their relationships.
