Kako izračunati Cold Plunge Protocol
Kaj je Cold Plunge Protocol?
The Cold Plunge Protocol Calculator estimates the safe duration for cold-water immersion based on water temperature, your experience level, and your goal (recovery, hormesis, or cold-shock alertness). Cold plunging — popularized by Wim Hof and researcher Dr. Andrew Huberman — exposes the body to water typically between 38–55°F (3–13°C) to trigger physiological adaptations including increased norepinephrine, brown adipose tissue activation, and improved recovery from exercise.
Formula
- T
- Water Temperature (°F or °C) — Cold plunge water temp — colder requires shorter duration
- D
- Duration (minutes) — Time submerged neck-down per session

- 1Enter water temperature in Fahrenheit or Celsius — most home cold plunges run 45–55°F
- 2Select experience level: beginner (<3 months), intermediate (3–12 months), or advanced (1+ years)
- 3Choose goal: recovery (post-exercise), hormesis (long-term adaptation), or cold-shock (morning alertness)
- 4Indicate pregnancy status — pregnant users get a 1-minute safety cap regardless of other inputs
- 5Calculator computes duration scaled by experience baseline, temperature factor, and goal modifier
- 6Weekly target follows Dr. Susanna Søberg's research: 11 minutes/week for beginners, up to 20 min for advanced
- 7Sessions per week derived from weekly target ÷ session duration, clamped between 2–6 per week
Worked Examples
Common Mistakes to Avoid
- ✕Going too long too soon — beginners should never exceed 2 minutes regardless of how comfortable they feel
- ✕Plunging at extreme temperatures (<35°F) without supervision — high risk of cold shock response or cardiac event
- ✕Ignoring pregnancy or cardiovascular contraindications — cold immersion is unsafe with uncontrolled hypertension, arrhythmia, or pregnancy without medical clearance
- ✕Plunging immediately after a heavy meal or alcohol — increases cardiac risk
Frequently Asked Questions
What is the minimum effective dose for cold plunging?
Dr. Susanna Søberg's research shows 11 minutes per week total cold exposure is the minimum for measurable adaptation. This can be split into 2–6 sessions per week of 1–5 minutes each.
Should I plunge in the morning or evening?
Morning is optimal for cold-shock alertness and metabolic activation. Evening plunges can disrupt sleep if done within 2 hours of bedtime.
Is shivering bad?
No — shivering is part of the adaptation response. However, prolonged shivering (>5 min after exit) suggests session was too long for your level. Reduce duration.
