Do acupressure mats actually work?

Across specialist subreddits (r/massage, r/Fibromyalgia, r/acupuncture, r/backpain) and mainstream wellness coverage, the anecdotal consensus is that mats reliably help with muscle tension, sleep onset, and minor back and neck pain after a short adjustment period — though reviewers themselves note that controlled scientific evidence is limited. Users typically describe the first 2–5 minutes as uncomfortable, followed by warmth and relaxation.
