“Light pressure on the eyeballs lowers heart rate, sometimes by quite a bit, by eliciting what’s called the oculocardiac reflex. It also stimulates the vagus nerve. The vagus nerve has an extensive resume: It regulates heart rate and digestion, and it’s the primary medium through which our belly brain regulates mood. It’s the main communicator to our rest-and-digest system, which helps us to relax more deeply. It also elicits our tend-and-befriend system, enabling us to reach out and connect with others. This is a critical factor in long-term stress resilience and, research shows, in happiness.” Bo Forbes para Yoga Journal
