If you’ve ever thought, "Why am I still this upset?" or "Why can’t I just calm down?", you’re not alone. Many of the adults I work with in therapy struggle with what happens after the emotion shows up. Anxiety spikes, shame floods in, anger bursts out, and then comes the second wave: self-criticism.
I shouldn’t be this sensitive.
Why do I overreact?
What’s wrong with me?
In this post in the Coping Skills Series, we’re looking at one very practical, science-informed tool: The 90 Second Rule for emotional regulation. This skill is simple, powerful, and surprisingly relieving once you understand how it works.
What Is the 90 Second Rule?
The 90 Second Rule is based on neuroscience research suggesting that when an emotion is triggered, the body’s initial chemical stress response lasts about 60 - 90 seconds. That means: when something upsetting happens, your nervous system activates, stress hormones are released, your heart rate shifts, your muscles tense. That physiological surge (if we don’t add to it with our thoughts) naturally rises and falls within about 90 seconds. But here’s the important part: most of us don’t experience just one 90sec wave. We experience dozens of waves. Why? Because we keep re-triggering the emotion with our thoughts.
Why Emotions Feel Like They Last Forever
Let’s say you send a vulnerable text and don’t get a reply. Your brain interprets that as possible rejection. Your body reacts: tight chest, drop in stomach, rush of heat, spike of anxiety... That first wave? About 90 seconds.
But then your mind jumps in:
They’re losing interest.
I knew this would happen.
I’m always too much.
I shouldn’t have sent that.
Each thought reactivates your nervous system. So what could have been a brief emotional surge becomes a 45 minute spiral.
The 90 Second Rule isn’t about suppressing emotion.
It’s about learning to ride the first wave without fuelling the next ten.
The Skill: How to Practise the 90 Second Rule
Here’s how to use it in real life.
Step 1: Name What’s Happening
Instead of "I’m freaking out", try:
"I’m noticing anxiety."
"This is a shame wave."
"My body is activated."
Naming helps you shift from being inside the emotion to observing it.
Step 2: Set a 90 Second Timer (Yes, Literally)
When possible, set a timer on your phone for 90 seconds. Tell yourself:
"For the next 90 seconds, my only job is to let this wave move through my body."
You are not solving the problem. You are not analysing. You are not fixing. You are riding.
Step 3: Focus on the Body, Not the Story
This is crucial. Your mind will try to pull you back into the narrative. Instead, gently redirect your attention to:
Where do I feel this in my body?
Is it hot, tight, buzzing, heavy?
Does it move or stay still?
Breathe slowly. Unclench your jaw. Drop your shoulders. Feel your feet on the ground. You are allowing the chemistry to metabolize.
Step 4: Notice What Changes
At the end of 90sec, ask:
Is the intensity the same?
Has it shifted even 5%?
Did it intensify and soften?
Most people notice at least a slight reduction. Not zero, but less. That’s emotional regulation in action.
What This Skill Is (And Isn’t)
It is:
A nervous system reset
A way to reduce escalation
A shame-reducing practice
A pause before reacting
It is not:
Emotional suppression
Avoidance
Telling yourself you "shouldn’t feel this way"
A guarantee the feeling disappears
The goal is not to eliminate emotion. The goal is to prevent one wave from becoming a storm.
Why This Matters If You Grew Up Walking on Eggshells
If you grew up in a home where emotions were dismissed, criticized, ignored, explosive, or unpredictable, your nervous system likely learned that big feelings are dangerous. So when emotion rises now, it doesn’t just feel uncomfortable, but instead it feels threatening.
That’s when people tend to shut down, lash out, over-apologize, over-explain, panic text, or mentally spiral. The 90-Second Rule helps retrain your system to learn:
“An emotion can rise and fall without me doing something drastic.”
Real-Life Examples of the 90-Second Rule
Example 1: Anxiety Before a Work Meeting
Your boss says, "Can we talk later?"
Cue stomach drop.
Instead of mentally rehearsing worst-case scenarios, you:
Notice the anxiety
Set a 90 second timer
Focus on your breath and feet on the floor
After 90 seconds, the intensity drops from 8/10 to 5/10. Now you can think more clearly.
Example 2: Shame After Oversharing
You leave a social gathering and think:
Why did I say that? I’m so awkward.
Instead of replaying the conversation for an hour, you:
Notice the heat in your face
Sit with it for 90 seconds
Let the discomfort move through
You still feel a bit embarrassed, but you don’t spiral into "I’m fundamentally unlikeable."
Example 3: Anger in a Relationship
Your partner forgets something important.
You feel a surge of anger and the urge to snap.
Instead, you excuse yourself for 90 seconds. You breathe. You notice the heat in your chest.
When you return, you can say, "I felt hurt when that happened", instead of attacking. That pause changes relationships.
Common Mistakes When Trying This Skill
1. Expecting the Emotion to Disappear
The goal is intensity reduction, not elimination.
2. Continuing the Story in Your Head
If you keep mentally arguing, you’re restarting the wave.
3. Judging Yourself for Needing the Skill
Needing regulation tools does not mean you’re broken. It means you’re human.
Why This Skill Works for Anxiety and Depression
For anxiety: It interrupts catastrophic thinking loops.
For depression: It helps prevent shame spirals and emotional shutdown.
For self-esteem struggles: It creates space between "I made a mistake" and "I am a mistake." That space is everything.
When the 90 Second Rule Isn’t Enough
Sometimes the wave doesn’t settle easily. That doesn’t mean you failed. It may mean:
The trigger connects to a deeper attachment wound.
There’s unresolved grief.
You’re chronically stressed or burnt out.
Your nervous system is already overloaded.
Coping skills are powerful, but they don’t replace deeper healing work. If you find that emotions regularly feel overwhelming, explosive, or shutting-down, therapy can help you understand why your system reacts the way it does and how to gently reshape those patterns.
A Gentle Practice to Try This Week
This week, don’t wait for a huge emotional event. Practise on smaller waves:
Mild frustration in traffic
Slight embarrassment
Low-level anxiety before a phone call
Build the muscle memory when the stakes are lower. The more you practise, the more automatic it becomes.
Final Thoughts: You’re Not "Too Emotional"
Emotions are not the problem. Unregulated spirals are. The 90-Second Rule teaches your nervous system:
"I can survive this wave without attacking myself or someone else."
That’s emotional maturity, resilience, and healing. And if you’re someone who was never taught how to ride emotional waves safely, it makes sense that this doesn’t come naturally yet. It’s a skill, and skills can be learned.
If you’re in Hamilton, ON and looking for psychotherapy support for anxiety, depression, or self-esteem challenges, I’d be glad to help. At Blue Hen Psychotherapy, I work with adults who want practical tools and deeper healing. You don’t have to manage emotional waves alone.
