People with asthma or other breathing difficulties can find mindfulness meditation challenging because of the focus on the breath.
Our meditation creator, Tamara, received a question from an asthmatic user about how to handle breathing exercises, and you may find her answer helpful for your meditation practice:
"How do you breathe in daily life? Breathe just like that. Don't worry about taking deep breaths. This practice involves learning and honoring our limitations. Breathe gently and lovingly and do the best you can."
Sometimes our physical bodies put limits on us that can make something like meditation seem difficult or impossible. It's important to remember that specific techniques - counting deep breaths, the upright sitting position, etc. - are simply a means to calm and relaxation, and there are many ways to get there.
Give our Body Scan, Loving-Kindness, and Non-Judgment meditations a try. They can be found in the 'Beginners' category in the Meditate menu. While these both reference the breath, the majority of the sessions focus elsewhere and you may find them easier to meditate with.
