Doctor Eye Health just sent out an email to talk about this study.
Apparently distress/anxiety/depression increases cortisol levels which increases intraocular pressure which in turn exacerbates glaucoma.
In light of that, according to this article there’s some evidence that meditation reduces intraocular pressure.
And this is how the article defines meditation:
" Meditation refers to a family of self-regulation practices that focus on training attention and awareness to bring mental processes under greater voluntary control and thereby foster general mental well-being and development and/or specific capacities such as calm, clarity, and concentration.8 During meditation, attention can be focused on a mantra, sound, or breath. Mindfulness meditation focused on the breath has an additional benefit as slow breathing activates the parasympathetic nervous system and counters the stress response."
In reality though, mindfulness meditation isn’t a one size fits all. The meditation right for you will vary from person to person and vary from time to time. So, if you do try out meditation keep that in mind that you may be doing one that is not well suited for you.
