Big Feelings Need Room: How to Move From Reacting to Processing

You’ve probably heard of fight-or-flight mode, your body's survival response that sends your heart racing and tenses your muscles when it senses danger. And there's a reason we say things like "my nerves are shot" or "you're getting on my last nerve." But you might not realize that the same nervous system response that primes your body to fight off a threat or run from it also shapes how you feel and react emotionally.

When you’re not in a regulated state, even a minor inconvenience can feel overwhelming: your throat tightens, the pressure builds as you fight back tears, and you become fixated on the thing that’s making you upset. If you can’t put your finger on why you’re having such a big emotional reaction, it could be tied back to a dysregulated nervous system. 

The truth is: it’s not your fault. When your body is stuck in fight-or-flight mode, the ripple effects can make stubbing your toe feel like the universe is out to get you.

The goal is to process these big feelings instead of reacting right away or avoiding them altogether. By calming your nervous system, you can sit with your feelings, move through them, and give yourself space to choose how you respond.

How Your Nervous System Influences Your Emotions 

If you spend any time on #TherapyTok, you’ll see people throw around terms like “overstimulated” and “dysregulated” to describe big emotional reactions. While these words are often overused, there’s real science behind the idea that the state of your nervous system affects how you feel and react.

When you’re dysregulated, your emotions tend to feel heightened and more dramatic, and you might even get annoyed with yourself, like whatever set you off shouldn’t be that big of a deal. And if those emotions lead to a reaction, you might feel embarrassed by how you responded once you’ve calmed down. 

Here’s what’s going on: when your body senses a threat, your amygdala, the brain's alarm center, goes on high alert. At the same time, stress can quickly weaken the prefrontal cortex, the part of your brain that helps you pause, see the bigger picture, and keep your emotions in check. As described in a 2009 review in Nature Reviews Neuroscience, stress that feels out of your control shifts the brain away from the "thoughtful" prefrontal cortex toward the "more primitive" responses of the amygdala.

This can make you more likely to read neutral or ambiguous moments as threats, which is why a curt reply from a barista can feel like a personal attack. In one 2017 study, people whose stress hormones spiked more after a stressful task rated ambiguous facial expressions more negatively.

Why Pushing Your Feelings Down Doesn’t Work 

When you have a big emotional reaction to something, you might have the instinct to push your feelings down to avoid dealing with them in the moment. After all, you don’t want to be seen as overly dramatic or too sensitive. Swallowing your frustration and pretending you’re fine seems like the more mature choice.

The problem with this approach is that pushing a feeling down doesn’t make it go away. In a classic 1993 study at UC Berkeley, researchers asked participants to suppress their emotions while watching an upsetting film clip. The people who hid their emotions didn’t feel any less upset than the people who reacted naturally. In the emotionally suppressed group, their bodies also displayed more signs of stress activation, like increased sweating. This study showed that the feeling was still there; their nervous systems were just working harder to keep it hidden. 

Even though big feelings can be uncomfortable in the moment and seem like a problem, they can actually teach us something. In his book A Simple Guide to Being Alive, Apollo co-founder Dr. Dave Rabin, MD, PhD, frames anxiety not as an enemy, but as a signal. 

And according to one influential theory of emotion, other feelings carry information, too: anger often signals that you've been slighted or treated unfairly, and sadness can indicate that you've lost something that really mattered. Processing means listening to that signal instead of drowning it out or acting on it right away. But that's hard to do when your body is still on high alert, which is why regulation comes first.

Regulate First, Feel Second

When your nervous system is in fight-or-flight mode, it's nearly impossible to sit with a feeling. Since your brain is focused on the perceived threat, the part that typically helps you pause and reflect is harder to access. Calming your nervous system first creates enough steadiness to actually feel what's happening without getting too overwhelmed by it.

That's where Apollo comes in. The Apollo wearable uses gentle vibrations that work like a soothing touch on your vagus nerve, helping shift your nervous system toward its "rest and digest" state. This not only helps your body physically calm down, but also impacts your mental well-being. We dive more into the science of how this works in “How Grounding Helps Your Body Catch Up."

Apollo has also been studied in people with some of the most intense stress responses. In a small two-week study of 16 people diagnosed with PTSD, many of them military veterans, participants reported improvements in mood, focus, and sleep, "with the greatest improvements in their ability to regulate emotions." And in a separate real-world survey of 241 Apollo users who self-reported PTSD, over 90% reported improvements after using Apollo for a month or more.

You don't need to have a PTSD diagnosis to benefit from the same principle: when your body feels steadier, there's more room to feel.

How to Make Room for Big Feelings

The next time a big feeling hits, try this sequence:

1. Regulate first. Turn on a calming Vibe with Apollo, slow your exhale, and give your body a minute before you say or do anything.

2. Acknowledge it. Notice that something is happening ("I'm having a big reaction right now") without acting on it yet.

3. Name it. Get as specific as you can with what you’re feeling: frustrated, hurt, embarrassed, disappointed. In one brain-imaging study, putting feelings into words reduced activity in the amygdala when people viewed upsetting images.

4. Let yourself feel it. Notice where the feeling shows up in your body, and let it rise and fall instead of fighting it.

5. Choose your response. Ask what the feeling is telling you and what you need. Then decide what's next: have the conversation tomorrow, take a walk, or text a friend.

Widen the Space Between Feeling and Reacting

You can’t escape the uncomfortable scenarios and everyday emotions that we all encounter as humans: you’re going to feel sad, angry, anxious, or upset sometimes, and that’s okay. The goal isn’t to completely avoid your feelings or become immune to big emotional events. 

Instead, aim to give yourself enough space to sit with your feelings and decide how to respond rather than impulsively reacting in the moment. And even if you snap at your partner for leaving the cabinet open yet again, that’s also human—having self awareness of what’s going on in our bodies and minds is the first step. 

Every time you regulate first before reacting, that space gets a little wider. And with Apollo as a steady cue you can reach for when a big feeling hits, you have support to move through these emotions.
