The New Immunity: Why Gut, Stress & Sleep Matter More Than Vitamin C

Modern Immunity Is a System

Immunity = gut + hormones + stress + sleep + inflammation.

Vitamin C is helpful, but not enough.

Stress Weakens Immunity

High cortisol suppresses gut immunity, reduces antibodies, and increases infections.

Poor Sleep Lowers Defense

Lack of deep sleep reduces:

  • T-cell function
  • Immune memory
  • Recovery

Gut Health = Immune Health

70% of immune cells live in your gut.
