Cold Plunge Protocol Card: Your Routine, Captured

Turn your plunge routine into a clean, shareable card — temperature, duration, frequency, and a short note. Save it, screenshot it, or share it.

A protocol is just your routine written down: how cold, how long, how often. The protocol card turns that into a clean visual — useful as a personal snapshot, a way to share what works with a friend, or a reminder of the plan you committed to.[1]

Your shareable plan card

Generate a clean card of your cold plunge plan — download it or share it on X, Reddit, or your group chat.

How the protocol card works

Enter your water temperature, session duration, weekly frequency, and an optional note or goal. The card renders a clean summary you can save as an image or share.

Keep the card honest. If your plan says 2 minutes at 10°C but you are actually doing 90 seconds at 12°C, put the real numbers on the card — a protocol that matches reality is one you will follow.

What a good protocol card includes

Temperature, duration, sessions per week, and a goal line. That is enough to communicate the whole routine. Weekly totals around 11 minutes remain the sensible anchor for most people.

If you share a card publicly, add your safety context too — who cleared you, what your precautions are. It keeps the conversation responsible.

Common questions

Can I share my protocol card on social media?

Yes. The card is designed to be shared — save it as an image and post it. Just keep the numbers honest and note your safety context.

What should my first protocol card say?

Start with what you actually do today: 1-2 minutes at 10-15°C, 2-3 sessions per week. Your card should reflect reality, not aspiration.

Is the protocol card stored anywhere?

No server storage. The card is rendered in your browser and you save or share it yourself.

Should I update my card as I progress?

Yes — that is the point. When your sessions grow, update the card. Watching your protocol evolve over months is motivating and keeps the plan honest.
