the lymphatic system does not have a central pump. It depends heavily on movement, breathing, hydration, muscle contraction, and healthy circulation. When it works well, it supports immune function, fluid balance, tissue repair, detoxification pathways, energy, recovery, and healthy aging. When it becomes sluggish or overwhelmed, people may notice puffiness, heaviness, slow recovery, or a general sense that their body is not clearing and renewing as well as it could.
