The Science Behind Journaling & Expression

By Kavita Patel, MA • 7/20/2025


Before we get into the research and the tips, I want to acknowledge something: if you're reading this, you're probably dealing with something real. That matters.

The Research Perspective

I want to be careful here because this gets oversimplified a lot.

The World Health Organization estimates that this affects approximately 1 in 4 people globally at some point in their lives. If you're reading this, the math says several of your close friends are dealing with something similar — they just haven't told you.

Moving Forward

A 2023 meta-analysis in the Journal of Clinical Psychology looked at this exact question. Here's what they found.

The Nuance Nobody Mentions

A friend of mine — a psychiatrist who's been practicing for 20 years — puts it this way: "Everyone thinks they're the only one dealing with this. The irony is that this universality is itself universal."

What I've Seen Work

A 2023 meta-analysis in the Journal of Clinical Psychology looked at this exact question. Here's what they found.

Here's my "right now" emergency list — things you can do in the next 60 seconds:

  • Splash cold water on your face. This triggers the mammalian dive reflex and immediately slows your heart rate.
  • Hold something cold. An ice cube, a frozen water bottle. The sensation interrupts the anxiety circuit.
  • Do the physiological sigh. Two quick inhales through your nose, then one long exhale through your mouth. Repeat three times.
  • Push your feet hard into the floor. This activates your proprioceptive system and grounds you in your body.
  • Hum or sing. The vibration stimulates your vagus nerve, which controls your parasympathetic (calming) nervous system.

Look — I know an article on the internet isn't going to solve everything you're dealing with. But if something in here resonated, that matters. It means you're paying attention to yourself. And that's the first step toward feeling better.

If you're struggling, please don't go through it alone. A therapist, a doctor, a crisis line — these resources exist because this stuff is hard, and nobody should have to figure it out by themselves.
