Here's what Exhale has to say about meditation: "It tames the mind and calms the body by bringing focus to the breath, leading your 'thinking' mind into a deeper state of relaxation and allowing you to let go of repetitive thoughts." Exhale also says meditation can boost the immune system, lower blood pressure and improve concentration.
