Mindful breathing exercise.

Mindful breathing exercise is a practice of focusing on your breath as a way to calm your mind and body. Some examples of mindful breathing exercises are:

• The 4-7-8 method: Breathe in for 4 seconds, hold for 7 seconds, and breathe out for 8 seconds.
  

• Starfish breathing: Use your fingers to guide your breathing. Trace your thumb with your index finger and breathe in, then trace your thumb with your middle finger and breathe out. Repeat with the other fingers.

• Mountain breathing: Stand or sit with a straight posture and breathe deeply. Imagine you are a mountain, stable and strong.

• Bubble breathing: Pretend you are blowing bubbles. Breathe in slowly and deeply, then breathe out slowly and gently. Imagine the bubbles floating away.
