Frequently asked
What is contrast therapy?
Contrast therapy alternates between heat exposure (such as a sauna session) and cold exposure (such as a cold plunge or ice bath) as part of a recovery routine. The practice is one of the oldest recorded recovery methods and is used as a general wellness tool — not a medical treatment. Always consult a healthcare professional before starting, particularly if you have cardiovascular concerns.
What's the difference between a traditional sauna and an infrared sauna for contrast therapy?
Both work for contrast therapy. Traditional saunas heat the surrounding air to 150–195 °F (65–90 °C); infrared saunas use radiant panels to warm the body directly at lower air temperatures (120–150 °F / 49–65 °C). Infrared models are faster to heat up and generally easier to install at home, making them a common starting point for a home contrast setup.
What temperature should a cold plunge be for contrast therapy?
Most home cold plunge users start in the 50–59 °F (10–15 °C) range and work toward colder temperatures over time as their tolerance builds. Purpose-built cold plunge units with chillers typically reach 39–45 °F (4–7 °C). There is no universally correct temperature — start conservatively and consult a healthcare professional before beginning.
How do I set up a home contrast therapy station with a sauna and cold plunge?
The most practical home setups pair an infrared sauna (1–2 person, 120V or 240V plug-in) with a purpose-built cold plunge tank that has a built-in chiller. A typical session alternates 10–20 minutes of heat with 2–5 minutes of cold, repeated for 2–3 rounds. Our team can help you find a sauna and cold plunge combination that fits your space and budget — book a consult to get started.
Is contrast therapy — sauna and cold plunge — safe for home use?
Sauna and cold plunge units designed for consumer wellness use are generally considered safe for healthy adults when used as directed. People with cardiovascular conditions, those who are pregnant, and anyone taking medications that affect heat or cold tolerance should consult a healthcare professional before starting. Always follow each device's manufacturer guidelines.
