How much can a short retreat do?
Even a few days away can be meaningful. A systematic review and meta-analysis indexed on PubMedfound traditional meditation retreats moderately effective, with a combined effect size of Hedge's g = 0.45 in pre-post analyses (n = 19) and g = 0.49 when compared with controls (n = 14). That research pooled many kinds of traditional retreats, so it does not tell you what a specific four-day program will do for you. What a weekend does reliably give you is time: several sessions of guided breathwork and meditation in a row, with no commute and fewer interruptions, under a teacher with over 17 years of experience.
