Episode notes
When we get sufficient u v b light in our eyes, a particular set of connections within the sympathetic nervous system is activated. Our spleen deploys immune cells and molecules that scavenge for an combat infection. If those infections arrive in your body, if you inhale them, or they get into your mouth or on your skin, your spleen meets those infections with a greater output. We are simply better at combating those infections, and therefore there's less infection floating around. In fact, hair grows more, skin turns over more, meaning it's going to look more youthful.
