"VeRelief Prime just works. Anyone who has an Oura Ring and uses VeRelief will see instant feedback showing reduced stress and increased restorative time. After a week of using VeRelief, I can see in my Oura Ring trends HRV, sleep and deep sleep increasing. There are many ways to switch FROM fight or flight TO rest and digest like the following: meditation, deep breathing, earthing, yawning, gargling water, yoga, praying and probably 30 more ways. The problem is they take practice and or a specific location for them to be beneficial. Meaning it can be difficult to perform yoga or gargle water while working from a desk. The VeRelief is a no brainer that can be used one ANYONE at ANYTIME and will instantly return that person to parasympathetic or rest and digest. The simplest description of VeRelief is that "It's an OFF switch for your nervous system." Great product."
