Your immune system is working for you 24/7 — but most people don’t understand how it actually functions or how to support it.

In this episode of Jonty & The Doc, we break down immunity in the simplest way possible — from how your body defends itself, to what really impacts your ability to stay healthy.

We cover:
The difference between innate vs adaptive immunity
Why sleep is more important than you think
The real role of vaccines (and how age changes the equation)
How stress, travel, and overtraining affect your immune system
Nutrition basics that actually support immunity
Simple daily habits that make a long-term difference

This is not about hacks or shortcuts - it’s about understanding how your body works and making better decisions every day.
