The duration of a breathwork session can vary widely depending on the technique and purpose:

• Quick stress-relief techniques: 1-5 minutes Examples: Harmonic Breathing, Box breathing, 4-7-8 technique.
  Useful for immediate calming in stressful situations
• Daily practice sessions: 10-20 minutes: Suitable for techniques like diaphragmatic breathing or alternate nostril breathing
  Often integrated into meditation or yoga routines
• Intermediate sessions: 20-40 minutes: May include a combination of techniques or more focused practices
  Common in group classes or guided sessions
• Extended sessions: 60-90 minutes: Often used for more intensive techniques like holotropic breathwork
  May include preparation and need a period of integration.
• Workshops or retreats: Several hours to multiple days
  Deep dive into various techniques, often combined with other practices

The key is to start with shorter durations and gradually increase as you become more comfortable. Even brief sessions can be beneficial, especially when practiced consistently. For beginners, 5-10 minute daily sessions are often recommended to build a sustainable practice.
