You’ve probably seen it.

People stepping into ice baths after workouts.
After sauna.
After stress.
After everything.

Cold exposure has gone from a niche practice to a daily ritual for millions. And while that’s exciting—because yes, cold can be incredibly powerful—there’s a critical nuance missing from the conversation right now.

A nuance that could mean the difference between adapting… and blunting your progress.

Today, I want to explain what’s actually happening in your body when you use cold—and why timing matters far more than most people realise.

And like any stressor, its effect depends on when you apply it.
