How long is a Cardisuit session?

A typical Cardisuit session lasts 20 to 50 minutes. Some users choose shorter sessions, especially when starting. Many people use the Cardisuit 2-3 times per week, while others prefer more frequent use depending on their personal routine and comfort level. There is no fixed protocol—session length and frequency should be based on individual response and comfort.

How is the Cardisuit different from CO₂ inhalation methods?

The Cardisuit delivers CO₂ exposure through the skin rather than through breathing. Your head remains outside the suit, and breathing stays completely normal throughout the session. This makes it a passive, external exposure method rather than an active breathing practice. The experience focuses on relaxation and recovery rather than breathing training, distinguishing it from devices like the Cardihaler which involve inhaling controlled CO₂ levels.

Is CO₂ dry bathing safe?

The Cardisuit is designed for controlled sessions in well-ventilated spaces when used as intended. CO₂ levels in the room generally remain stable during a session, though they may temporarily increase when the suit is emptied. Normal ventilation quickly restores levels. If you are pregnant, have a diagnosed medical condition, or have concerns about CO₂ exposure, review the Cardisuit user manual and consult a qualified healthcare professional before use.

What does a CO₂ bath feel like?

User experiences with the Cardisuit vary between individuals. Many people describe sensations of deep relaxation, warmth, calm, or a grounding feeling during sessions. Some users report feeling mentally quiet or experiencing a restorative quality. The experience is generally passive and calm, as you remain seated or lying down throughout the session. Individual responses depend on personal sensitivity and session familiarity.

How does CO₂ absorption through skin work?

Carbon dioxide can pass through the skin during external exposure. During a Cardisuit session, CO₂ surrounds the body and is absorbed passively while breathing remains normal through the head, which stays outside the suit. This is distinct from inhaling CO₂—exposure occurs externally while you breathe regular air. The Cardisuit is designed for relaxation and recovery routines as part of general wellness practices, not as a medical treatment.

What is a CO₂ dry bath?

A CO₂ dry bath involves surrounding the body with carbon dioxide gas in a controlled environment, typically while seated or lying down. The Cardisuit creates a full-body CO₂ dry bath that covers the body up to the neck, allowing passive CO₂ exposure through the skin. Unlike water-based CO₂ baths used in some spa settings, the Cardisuit uses CO₂ gas only. This approach has been explored in wellness and spa environments for its effects on relaxation and comfort.
