The Glymphatic System: The Hidden Network Supporting Your Brain and Nervous System (opens the original)
Read excerpt
In my last article, we followed the lymphatic system through the body and looked at something most of us rarely think about: the fluid surrounding our cells has to keep moving.Our cells are constantly taking in oxygen and nutrients, sending and receiving chemical messages, and producing the normal leftovers that come from being alive. The lymphatic system helps manage that environment throughout most of the body by collecting fluid and other
The Lymphatic System: Why It Matters for Nervous System Regulation (opens the original)
Read excerpt
Most of us have at least a rough picture of what the heart, lungs, liver and kidneys are doing.

How Anger, Sadness, Cynicism, and Sarcasm Affect the Nervous System (opens the original)
Read excerpt
In my previous article, I wrote about curiosity, awe, laughter and joy, and some of the surprisingly different ways those experiences can affect the nervous system.But there is another side to that conversation.The relationship between emotions and the nervous system is more complex than simply dividing feelings into positive and negative.A healthy nervous system is not one that stays cheerful, calm and positive all the time.
