When Anxious

Anxiety doesn’t schedule itself. It arrives in meetings, before sleep, mid-call, in line at airports — in moments you didn’t plan to need help. When Anxious is a 60-second breathing exercise for that exact arrival.

The technique is called box breathing: four in, four held, four out, four held. It’s used by Navy SEALs, first responders, and athletes because it engages the vagus nerve and slows the heart rate within four cycles.

There’s no account, no app, no notifications. Open it when your chest tightens.

What is box breathing?

A breathing pattern of four counts in, four held, four out, four held. Each cycle takes 16 seconds. The technique was popularized by Navy SEAL Mark Divine.

How does it help with anxiety?

The extended exhale and breath holds activate the vagus nerve, which signals the parasympathetic nervous system to slow your heart rate and reduce stress hormones.

How long do I need to do it?

Most people feel a measurable shift after four cycles — about one minute. Longer sessions deepen the effect.
