Box Breathing (3 mins)
26 Jan, 2026Box breathing is a simple breathing technique and has been used by the military and also in clinical settings for acute stress regulation.
Here's how to do it:

Tips:
- Start with shorter hold times (e.g., 2-3 seconds) if 4 seconds feels challenging, then gradually increase.
