We explore cyclic sighing, a simple breathing technique that can help lift your mood and lower anxiety by supporting your parasympathetic nervous system.

Summary: Cyclic sighing is a breathing exercise that involves inhaling through your nose, filling your lungs, and then slowly exhaling through your mouth. The idea is to inhale briefly but deeply, and then exhale for longer. Research suggests that the slow exhale is what's most relaxing, and can trigger a self-soothing response in the parasympathetic nervous system. 

Time: 5 minutes

1. Prepare: Find a comfortable seated or standing position in a quiet environment. Relax your shoulders and jaw. 


2. First Inhale: Inhale slowly and deeply through your nose. Start with your abdomen, allowing it to expand (diaphragmatic breathing) as you fill your lungs about halfway. Hold this breath briefly. 


3. Second Inhale: Continue inhaling through your nose, now expanding your chest to completely fill your lungs. Hold this combined breath (abdomen and chest filled) for a moment. 


4. Exhale: Exhale slowly and completely through your mouth. Make sure the exhale is gentle and lasts about twice as long as the combined inhales. 
   Repeat the Cycle: Repeat the inhale sequence for a total of 3 cycles (or as desired): Start with a diaphragmatic inhale through your nose, expanding your abdomen. Follow with a chest expansion inhale through your nose to fill your lungs completely. Hold briefly after each combined inhale. Exhale slowly and completely through your mouth, ensuring it's twice as long as the inhales. 


5. Reflect and Relax: After completing the cycles, take a moment to observe how your body feels. Notice any sensations of relaxation, reduced tension, or a calmer state of mind.
