What is Square Breathing / Box Breathing?
Box breathing is a simple breathing technique. It’s also called square breathing or 4-4-4-4 breathing.
The name comes from its pattern. You breathe in four equal parts. Each part lasts the same amount of time.
This creates a “box” or “square” pattern. It’s like drawing a box with your breath.
How Square Breathing Works
The technique follows four steps:
- Inhale for 4 counts
- Hold your breath for 4 counts
- Exhale for 4 counts
- Hold empty lungs for 4 counts
Then you repeat the cycle. Each side of the breathing “square” is equal.
Step-by-Step Instructions
Start by sitting comfortably. Keep your back straight.
Step 1: Breathe in slowly through your nose. Count to 4.
Step 2: Hold your breath. Count to 4 again.
Step 3: Exhale slowly through your mouth. Count to 4.
Step 4: Hold your empty lungs. Count to 4.
Repeat this cycle 4-8 times. You can do it anywhere.
