The Experiment: No warm water. At all. For 30 days. The knob stays on the coldest setting (approx 50°F / 10°C). Science says it boosts immunity and testosterone. My brain says it is torture.

> THE TEMPERATURE

MY SHOWER (10°C)

> DAY 1: THE GASP

I stepped in. My body involuntarily gasped. This is the "Mammalian Dive Reflex."

[00:05] - REGRET.
[00:15] - I cannot maximize my lungs.
[00:30] - Is that numbness or death?

I lasted 45 seconds. I felt like I had just run a sprint. My heart rate was 140 BPM standing still.

> DAY 7: THE DREAD

The hardest part isn't the shower. It's the anticipation of the shower.

I found myself procrastinating hygiene. "Do I really need to shower today? I didn't sweat."

INTERNAL SCREAM VOLUME: 110%

> DAY 15: THE ADAPTATION

Something weird happened. I stepped in, and the shock only lasted 3 seconds. Then, I felt... warm?

My body created a heat shield (Brown Fat activation). I stood under the freezing water and felt invincible. I started singing.

> THE BENEFITS ANALYSIS

ENERGY

Better than coffee. The adrenaline spike wakes you up instantly. No crash at noon.

DISCIPLINE

Doing something you hate every morning makes everything else easy. "Tax returns? At least it's not the shower."

SKIN/HAIR

Noticeable. Hot water strips oils. Cold water seals pores. My hair is softer.

IMMUNITY

My roommate got the flu. I did not. Coincidence? Maybe. But Wim Hof says no.

> DAY 30: THE FINAL VERDICT

I turned the knob to "Hot" for the first time in a month.

It felt... disgusting. It felt suffocating. I actually turned it back to cold.

I have been converted. I am now one of those annoying "Cold Shower People." I apologize in advance.

> CONCLUSION

You don't need caffeine. You need thermal shock.
