FAQs

Innie and Outtie is a hot and cold therapy brand built around contrast therapy, combining sauna and cold plunge into one connected system. It pairs premium hardware with an app that guides you through hot, cold, and contrast sessions.

Contrast therapy is the practice of alternating between heat and cold, typically sauna followed by cold plunge, to trigger circulation, recovery, and nervous system benefits that neither hot nor cold delivers alone.

Yes. The app lets you run one therapy at a time, sauna only or cold plunge only, or select Contrast Therapy mode to combine both in a single guided session.

Yes, when approached gradually. Start with shorter exposures at a higher temperature and let your body adapt before extending time or lowering temperature. The app's built in timer cap exists specifically to keep sessions within a safe range.

Sessions are capped at 15 minutes maximum for safety. Most users start with two to three minutes and build tolerance over time rather than pushing straight to the limit.

Most people see benefits from three to five sessions per week, though daily use is common once you're acclimated. Consistency matters more than intensity.

Cold exposure is linked to improved circulation, reduced inflammation, faster muscle recovery, and a noticeable mental reset. Many users report better sleep and sharper focus with regular use.

Sauna use raises core temperature to promote detoxification through sweat, ease muscle tension, support cardiovascular health, and trigger a relaxation response similar to light exercise.

The app is designed to pair with Innie and Outtie hardware for the full guided experience, including session tracking and timer control, but core content and education are accessible on their own.

The system centres on a sauna unit and a cold plunge barrel with chiller, built for real home installation rather than a scaled down version of a commercial setup.

Anyone serious about recovery and resilience, from everyday people building a wellness routine to athletes managing training load. The system is built for home use, not gym or spa environments.

It is built as one connected hot and cold system rather than a standalone tub. The app governs both sides of the therapy, so contrast sessions are guided rather than something you have to time and manage yourself.

Yes. Innie and Outtie includes a companion community where users share routines, progress, and results alongside app guided sessions.

Set up your hardware, download the app, and begin with a single therapy, sauna or cold plunge, before progressing to full contrast sessions once you're comfortable with each side individually.
