The 3-3-3 rule in psychology is often related to anxiety or grounding techniques. Here’s how it works:

1. Notice 3 things you see around you.
2. Identify 3 things you hear.
3. Move 3 parts of your body (e.g., fingers, toes, arms).

This exercise helps ground you in the present moment, reducing anxiety or stress by shifting focus to your surroundings and physical sensations.
