A NEW BOOK BY LEO LOPEZ

Interrupt
Stress in
90 Seconds.

The 90-Second Reset is the neuroscience-backed system to break the stress loop, calm your nervous system, and rewire how your body responds to pressure — in less time than it takes to check your phone.

Built on the research of Jill Bolte Taylor, Stephen Porges,
Robert Sapolsky, and Bessel van der Kolk

The 90-Second Reset book cover by Leo Lopez.
"Your stress has a 90-second lifespan. Everything after that is the loop you built around it."

— from Chapter One

A Complete System to Interrupt the Stress Response

01 / INTERRUPT

Stop Stress in 90 Seconds

Seven body-based protocols, each under two minutes. Each one engineered to interrupt a specific stress state at its biological source. Nothing to download. Nothing to buy. Nothing to fake.

02 / MAP

Break the Stress Loops Running Your Life

A forensic framework — trigger, body, thought, behavior, aftermath — that exposes the three or four stress patterns silently shaping your days. Once you see the loop, you can interrupt it.

03 / REWIRE

Rewire Your Nervous System in 21 Days

A 21-day capacity build that turns each reset into a rep. Lower resting heart rate. Higher heart rate variability. Faster recovery from conflict. A measurably different physiology by the end.

How to Calm Down in 90 Seconds — Try It Now

Ninety seconds. No app. No equipment. The Universal Reset is the protocol the rest of the book is built on. If it works for you here, the book is for you.

The Universal Reset

Ninety seconds. Anywhere. When you do not know which loop is firing.

  1. 1.Feet flat on the floor. Weight even. One normal breath.
  2. 2.Inhale four counts through the nose. Exhale eight counts through pursed lips. Four cycles.
  3. 3.Soften the jaw. Soften the gaze. Let the shoulders drop.
  4. 4.One final normal breath. Say silently: "I am here. The loop is not me."

Seven Stress Loops. Seven 90-Second Resets.

Each reset is mapped to a specific stress state that most adults face every week. Morning anxiety. The mid-conversation flood. The 3 PM crash. The 3 AM spiral. The Sunday night dread. Find the one that matches the moment. Run it in 90 seconds.

CHAPTER 06

The Morning Dread Reset

For the morning anxiety that hits before your feet touch the floor — the cortisol awakening response, amplified by your phone.

CHAPTER 07

The Mid-Conversation Flood Reset

For the moment a sentence lands and your prefrontal cortex goes offline — the amygdala hijack that ruins meetings and conversations.

CHAPTER 08

The 3 PM Crash Reset

For the afternoon energy drop coffee will not fix — an ultradian dip in disguise, and how to answer it correctly.

CHAPTER 09

The Doom Scroll Reset

For the doom scroll anxiety loop that eats an hour you did not know you were spending — and how to interrupt it without willpower.

CHAPTER 10

The Conflict Spike Reset

For the ninety seconds before you say the thing you will regret — a conflict de-escalation protocol you can run in plain sight.

CHAPTER 11

The Insomnia Spiral Reset

For 3 AM anxiety, when your brain is wrong and you cannot tell. The protocol that returns you to sleep without negotiating with the spiral.

CHAPTER 12

The Sunday Night Reset

For sunday night anxiety — the anticipatory dread that ruins the evening and contaminates Monday. Close the open loops in three minutes.

The 21-Day Nervous System Protocol

The resets are the tactical layer. The 21-day protocol is the transformation. Five minutes a day. Twenty-one days. A measurably different nervous system at the end.

1

Week One — Awareness

Catch the stress loop in real time, before it spends an hour of your day.

2

Week Two — Interruption

Run the matched reset every time the loop fires. Build the new neural path.

3

Week Three — Replacement

The old pattern weakens. The new one installs. Your baseline shifts.

Includes the daily tracker, weekly milestones, and troubleshooting protocols inside the book.

The Neuroscience Behind the 90-Second Reset

Stress chemistry has a 90-second lifespan in the body. Dr. Jill Bolte Taylor's research established the window. After 90 seconds, what feels like ongoing stress is no longer chemistry — it is the loop your nervous system is replaying. The 90-Second Reset uses that window: it interrupts the stress response at the biological source, then trains the vagus nerve and parasympathetic recovery over 21 days. The same mechanism behind the physiological sigh, polyvagal toning, and the completing-the-stress-cycle research is packaged here as one protocol you can actually use.

Built on the field's most cited research.

  • Jill Bolte TaylorThe 90-second rule of emotion.
  • Stephen PorgesPolyvagal theory and vagal tone.
  • Robert SapolskyStress biology and the cortisol cascade.
  • Bessel van der KolkBody-first intervention.
  • Emily and Amelia NagoskiCompleting the stress cycle.
  • Andrew HubermanAutonomic nervous system mechanics.

Written for Anyone with a Nervous System Running Hot

If you have tried meditation apps, breathing exercises, journals, supplements, and willpower — and none of it stuck — this book is for you. The protocols work the same in a CEO, a nurse, a new parent, a teenager, a teacher, and a retiree. The autonomic nervous system is identical across every reader on earth. So is the protocol.

EARLY READERS

"I have recommended stress tools for years. This is the first protocol short enough that my patients actually use it. The specificity of the seven resets is what changes everything."

— Dr. Sarah Chen, Physician, Internal Medicine

"I ran the Universal Reset in a board meeting with my camera on and no one noticed. By the time the next agenda item started, I was back. That is the only endorsement this book needs."

— Marcus Webb, COO, Series B technology company

"I bought six copies. One for each of my night-shift nurses. The 3 AM protocol alone is worth the price. This is the book I wish existed three years ago."

Frequently Asked Questions

Does the 90-second rule actually work?

Yes — and the science is older than most readers assume. The stress hormones triggered by a stressor clear the bloodstream in about 90 seconds. After that, what you are feeling is the mental loop replaying the event. The 90-Second Reset uses the window before the loop installs.

How is this different from other vagus nerve or nervous system reset books?

Most books in the category teach a toolbox of techniques. The 90-Second Reset teaches one mechanism — the 90-second interruption — applied to seven specific stress moments, and then built into a 21-day protocol that rewires the baseline. It is a system, not a list.

Can I read the book if I have anxiety, PTSD, or panic attacks?

The protocols are safe for general use and are widely used as complementary tools alongside therapy. The book includes clear guidance on when to seek professional support and a directory of resources. It is not a replacement for clinical care.

How long until I notice a difference?

Most readers feel a state shift the first time they run the Universal Reset. Baseline change — calmer mornings, faster conflict recovery, deeper sleep — is the target of the 21-day protocol.

Do I need any equipment, an app, or a meditation practice?

No. Every reset uses only your body, your breath, and 90 seconds. You can run them in bed, in a meeting, on a bus, or mid-conversation. They are designed to be invisible in public.

Is the book good for morning anxiety, 3 AM anxiety, or Sunday night anxiety specifically?

Yes. Three of the seven resets target exactly those moments: the Morning Dread Reset, the Insomnia Spiral Reset, and the Sunday Night Reset. Each chapter is self-contained, so you can go straight to the one you need.
