While breathwork is generally safe, it’s not universally suitable for everyone without precautions:

Safe for most:
• Basic techniques like diaphragmatic breathing are safe for the majority.
• Gentle practices can often be adapted for various health conditions.
• If you are concerned, breathing gently and rhythmically in and out through the nose, is perfectly safe for all conditions. Allow your body to set the pace that feels good for you.

Caution advised:
• Pregnant women should consult healthcare providers before trying new techniques.
• People with respiratory conditions like asthma or COPD should start gently and be mindful of any discomfort.
• Those with cardiovascular issues should avoid practices that drastically alter heart rate or blood pressure.

Contraindications:
• Certain techniques may be unsuitable for people with glaucoma or detached retina.
• Those with recent injuries or surgeries should consult their doctor before starting.
• Individuals with mental health conditions, especially those prone to dissociation, should approach intense techniques cautiously.

General precautions:
• Start slowly and build up gradually.
• Be aware of lightheadedness or dizziness, especially with rapid breathing techniques.
• For intense practices like holotropic breathwork, professional supervision is recommended.

It’s always advisable to consult with a healthcare professional before starting any new breathwork practice, especially if you have pre-existing health conditions.
