EP 22 “Morning UVA light is what signals your body to produce melanin so you can actually tolerate midday sun safely.” —Christy Nault

Today On The Cellular Upgrade:

  • A soft return to circadian rhythm and natural light, and how your body remembers how to heal when you follow the sun
  • The gentle dance between UVA, UVB, and vitamin D, and why timing your sunlight changes everything
  • A new lens on skin health and inflammation, beyond what we’ve been taught to fear
  • How morning light and nervous system balance quietly reset your energy, mood, and metabolism
  • The connection between sunlight, immune health, and histamine balance, and what your body has been asking for all along
