Clearing fluid and waste products from the interstitial space into the lymphatic system is important for health.

“Well, when you learn how the lymphatic system works, when you understand about how lymph can pool, how fluid can accumulate in the interstitial space if it's not getting cleared by the lymphatic system, and when you understand the both superficial vessels and deeper vessels of the lymphatic system are related to light touch at the surface in the proper directions and the drainage out of the head and neck as well as accessing the deeper lymphatic vessels that are associated with the fascia, it all makes perfect sense.”
