Hyperbaric Oxygen Therapy (HBOT) has garnered significant attention as a holistic approach to enhancing wellness, accelerating recovery, and promoting overall health. Among the varying pressure levels of HBOT, the use of 1.3ATA pressure stands out for its safety and efficacy, particularly for general wellness purposes. This article explores the nuances and benefits of Hyperbaric Oxygen Therapy at 1.3ATA and how it compares to higher pressures, such as 2-3ATA.
What is Hyperbaric Oxygen Therapy?
Hyperbaric Oxygen Therapy, or HBOT for short, involves breathing pure as possible oxygen in a pressurised chamber. This process increases oxygen levels in the bloodstream and tissues which stimulates healing, reduces inflammation, and improves cellular function.
The “ATA” (atmospheres absolute) unit measures pressure in the chamber. Standard atmospheric pressure at sea level is 1.0ATA. For HBOT, the pressure is increased, with 1.3ATA being one of the most common levels used for wellness purposes.

A healthy reading of blood oxygen levels is 95%SpO2 and above.
Understanding 1.3ATA vs. 2-3ATA HBOT
1.3ATA – General Wellness
Ideal for General Wellness: 1.3ATA is considered a “mild hyperbaric” setting. It provides a gentle boost in oxygen absorption, making it safe and suitable for individuals seeking to enhance overall health and recovery without medical concerns.
Non-Invasive and Comfortable: The lower pressure ensures a comfortable experience, with minimal risk of adverse effects such as barotrauma (ear or sinus discomfort).
Support for Recovery and Performance: This pressure level promotes faster recovery after illness or injury, enhances energy levels, and supports cognitive clarity.
2-3ATA – Designed for Medical Treatments
Used in Clinical Applications: Pressures of 2.0ATA and higher are primarily used for medical conditions such as carbon monoxide poisoning, non-healing wounds, and severe infections.
Greater Oxygen Saturation: These pressures deliver higher oxygen saturation to the bloodstream, providing therapeutic effects for specific conditions.
Requires Supervision: Due to the increased risk of oxygen toxicity and other side effects, higher-pressure HBOT should only be administered under medical supervision.
Why Choose 1.3ATA for General Wellness?
SAFETY FIRST
At 1.3ATA, experts consider the therapy as non-invasive and safe for most people, including children and older adults. It does not require the stringent medical oversight necessary for higher pressures, making it accessible to a wider audience.
ENHANCED RECOVERY
For athletes, fitness enthusiasts, or those recovering from surgery, injuries, or chronic conditions, 1.3ATA supports quicker healing by reducing inflammation and enhancing oxygen delivery to tissues.
IMPROVED COGNITIVE FUNCTION AND EMOTIONAL WELLBEING
Increased oxygen can boost brain function, reduce mental fatigue, and alleviate symptoms of stress and anxiety.
HOLISTIC BENEFITS
Regular sessions at 1.3ATA can improve skin health, strengthen the immune system, and contribute to better sleep quality.
Who Can Benefit from 1.3ATA HBOT?
- Fitness Enthusiasts: For recovery and enhanced endurance.
- Professionals: To combat fatigue and improve focus.
- Ageing Adults: To maintain vitality and support longevity.
- Wellness Seekers: For overall physical and mental balance.
- Individuals in Recovery: Those recovering from surgery, injuries, or cancer treatments.

Safe & Effective Therapy For All
Hyperbaric Oxygen Therapy at 1.3ATA is a powerful yet gentle solution for individuals seeking to enhance their health and recovery safely. While higher pressures like 2-3ATA have their place in medical treatments, 1.3ATA offers a non-invasive, accessible option for wellness support ensuring safety and efficacy for mild hyperbaric use.
At Arc Holistic Wellness, we infuse 60% oxygen at 1.3ATA in our hyperbaric chamber, offering a safe and effective amount for regular therapy. We carefully calibrate this oxygen level to avoid the risks of over-absorption, ensuring the treatment remains both beneficial and gentle on the body. Additionally, we can adjust our chamber to an even lower pressure of 1.1ATA, catering to individuals who may be more sensitive to pressure changes or need a more gradual introduction to HBOT.
Arc’s hyperbaric chamber is made and imported from Japan, a country renowned for its precise engineering and quality certifications. This ensures the highest standards of safety, reliability, and performance, giving our clients peace of mind during every session.
Our centre is also mobility-friendly, making the therapy accessible to those who require additional support, ensuring everyone can experience the benefits of HBOT comfortably and safely.
Whatever your need, whether you’re recovering from a health challenge, or someone looking to prioritise your wellbeing, HBOT at 1.3ATA could be the key to unlocking your body’s full potential!
