Why 2 Minutes Actually Works
People ask me a lot about the science behind Baseline. What it's built on. Why two minutes. Whether this is real or just another wellness trend dressed up in nicer language.
Fair questions. So here's the research — broken down into pieces that actually make sense, with the studies linked so you can go as deep as you want.
There's a lot more nuance to all of this than a single blog post can hold. But starting somewhere felt important.
Your nervous system isn't just "on" or "off"
Most of us grew up with a simple picture of stress: there's fight-or-flight, and there's calm. Two modes. You're either stressed or you're not.
Polyvagal Theory, developed by neuroscientist Stephen Porges, shows it's more complex than that. Your autonomic nervous system — the part that runs in the background without you thinking about it — actually moves between three states.
There's the ventral vagal state — what most of us would call feeling safe, present, and connected. You can think clearly, engage with people, and respond flexibly to what's happening around you.
There's the sympathetic state — the classic fight-or-flight response. Heart rate up, muscles tense, cortisol and adrenaline flowing. This is useful in the short term. It sharpens focus, mobilises energy, and helps you perform under pressure.
And there's the dorsal vagal state — shutdown. When the system is overwhelmed beyond what fight-or-flight can handle, it conserves energy by pulling you offline. This can feel like numbness, brain fog, disconnection, or that heavy "I just can't" feeling.
The key insight from Polyvagal Theory isn't that these states exist — it's that your nervous system moves between them constantly, and that the state you're in fundamentally shapes your experience. The same meeting feels manageable in one state and unbearable in another. The same email reads as neutral or threatening depending on where your system is sitting.
Baseline uses this framework to meet you where you actually are. When you open the app and check in. It's identifying your nervous system state and matching a tool designed to shift that specific state.

When stress stays too long, your brain physically changes
Stress in the short term is adaptive. It's your system doing exactly what it's designed to do — rising to meet a challenge and then coming back down.
The problem starts when it doesn't come back down.
Bruce McEwen's research at Rockefeller University showed that chronic stress creates something called allostatic load— essentially the cumulative wear and tear on the body when stress responses stay activated over long periods. And the effects aren't abstract. They're structural.
Chronic stress disrupts the neural circuits responsible for decision-making, emotional regulation, and memory. The prefrontal cortex — the part of your brain that handles clear thinking, planning, and impulse control — actually shrinks under sustained cortisol exposure. Meanwhile, the amygdala — the brain's threat detection centre — grows more reactive.
In practical terms, this means chronic stress doesn't just feel bad. It changes how your brain processes information. You make worse decisions. You react more and respond less. Your capacity for creativity, patience, and presence genuinely diminishes — not because you're less capable, but because the hardware is running a different programme.
And here's the part most people miss: this adaptation is gradual and invisible. Your system doesn't announce that it's recalibrating around stress. It just quietly shifts what "normal" looks like until you can't remember what baseline actually feels like.
The good news — and the reason Baseline exists — is that this process works in both directions. The same neuroplasticity that lets your system adapt to chronic stress also allows it to recalibrate back. But it needs repeated experiences of actually being in a different state to do so. Not just knowing about it. Feeling it.

Your breath is a direct line to your nervous system
Here's something worth understanding: your breath is one of the very few functions in your body that operates both automatically and voluntarily. You don't have to think about breathing — but you can choose to change it. That dual nature makes it a direct interface between your conscious mind and your autonomic nervous system.
When you slow your breathing — specifically to around 5-6 breaths per minute — you stimulate the vagus nerve, the longest nerve in your body, which runs from your brainstem through your chest and into your abdomen. The vagus nerve is the primary channel of your parasympathetic nervous system — the branch responsible for rest, recovery, and returning to baseline after stress.
Gerritsen and Band's landmark study at Leiden University proposed a model they called respiratory vagal nerve stimulation — essentially showing that the physical act of slow, controlled breathing directly activates the vagus nerve, which triggers a cascade of measurable physiological changes. Heart rate decreases. Blood pressure drops. Cortisol levels fall — by up to 23% in some studies. The prefrontal cortex comes back online.
This is why "just breathe" isn't as simplistic as it sounds. It's not a platitude — it's a neurophysiological mechanism. Your breath literally speaks to your nervous system in a language that thinking can't.
But not all breathing is equal. The research points to specific patterns — slow, diaphragmatic, with an emphasis on a longer exhale — as being most effective for vagal activation. This is what Baseline's tools are built on. Not generic breathing exercises, but specific patterns designed to activate specific physiological responses.

Breathwork outperforms meditation for immediate stress relief
This is the one that tends to surprise people.
A study published in Cell Reports Medicine — led by researchers at Stanford including Andrew Huberman and David Spiegel — directly compared structured breathing practices with mindfulness meditation in a randomised controlled trial.
The finding: breathwork produced greater improvement in mood and greater reduction in physiological arousal than meditation. Both helped with anxiety, but breathwork shifted the body's stress response faster and more effectively.
The most effective technique in the study was something called cyclic sighing — a simple pattern of a double inhale through the nose followed by a long exhale through the mouth. Five minutes of this daily produced measurable improvements in mood and stress markers.
This matters for how Baseline is designed. The tools in the app aren't meditation. They're not asking you to observe your thoughts or sit with discomfort. They're body-first interventions that create a physiological shift your nervous system can feel — and the research suggests this approach works faster than the alternatives.
That doesn't mean meditation isn't valuable — it is, profoundly so, for many people and many purposes. But when you're in the middle of your day and you need to shift your state in two minutes, a somatic tool is more effective than trying to quiet your mind.

Breath + body = 150% more effective
The final piece of the puzzle — and the one that most directly shapes how Baseline's tools are designed.
Researchers at Vanderbilt University School of Medicine and Harvard Medical School studied what happens when you combine paced breathing with gentle rhythmic muscle engagement — essentially coordinating breath with body movement.
The results were striking. Paced breathing combined with alternating muscle contractions produced 150% higher parasympathetic activation than doing nothing. It was also significantly more effective than breathing alone or movement alone. The combination created a more resilient stress response — meaning participants maintained their calm even when subsequently exposed to a cognitive stressor.
This is why Baseline's resets aren't just breathing exercises. They pair breathwork with somatic cues — gentle body-based prompts that engage your muscles, your posture, or your physical awareness alongside the breath. The research shows that when your body and breath work together, the signal to your nervous system is dramatically stronger.
It's also why the tools are short. The parasympathetic shift begins within 60-90 seconds. You don't need twenty minutes. You need the right combination of inputs, delivered at the right moment, for long enough for your nervous system to register the signal.

What this means for you
The research is clear on a few things.
Your nervous system state shapes everything — how you think, how you feel, how you show up. Chronic stress physically changes your brain, but that process is reversible. Your breath is a direct line to your vagus nerve. Body-first tools shift your stress response faster than thinking-based approaches. And the combination of breath and body is more powerful than either alone.
That's what Baseline is built on. Not trends. Not intuition. Peer-reviewed research from Stanford, Harvard, Vanderbilt, and the leading researchers in autonomic neuroscience.
