Hyperbaric Oxygen Therapy (HBOT) is an exciting and rapidly evolving treatment in the wellness sector. While commonly used in medical settings to treat various chronic conditions, HBOT is becoming increasingly prevalent in biohacking treatments to improve overall wellness, performance, and longevity.
At Re:nu, we’ve seen first-hand how this powerful and effective therapy is helping clients take proactive steps towards optimal health. Whether recovering from an injury, seeking to optimise athletic performance, or looking to enhance their overall well-being, the advantages of hyperbaric oxygen therapy are game-changing.
In this guide, we’ll walk you through everything you need to know about HBOT in 2025, answering common questions like what is HBOT and what does hyperbaric oxygen therapy do, as well as giving you essential insight into what a Re:nu HBOT session includes.
Experience oxygen-powered recovery for peak performance and well-being.
What is HBOT Treatment?
Hyperbaric Oxygen Therapy is an effective way of increasing oxygen to tissues and organs. This non-invasive treatment involves breathing concentrated oxygen in a special pressurised chamber, allowing the lungs to absorb more oxygen and deliver it throughout the body.
Oxygen is essential for maintaining every cell in the body, so enhancing oxygen delivery and saturation offers a whole host of benefits, from increasing energy to accelerating healing to improving mental clarity. It really is a fantastic all-around treatment.
What is a HBOT Session at Re:nu Like?
When you arrive at our Re:nu wellness centre, a trained team member will walk you through the HBOT process, explaining the changes in air pressure and how you may feel during and after your treatment.
If needed, they’ll help you into the hyperbaric oxygen therapy chamber before fitting your specialist breathing equipment. Once you’re ready, lie back as the pressure gradually increases, allowing you time to adjust to the changes in the atmosphere.
Our hyperbaric chambers are designed to create a truly relaxing experience. We recommend arriving in your comfiest cotton clothing and bringing anything you wish that will help you unwind – you can listen to music, read a book, or simply take the time to switch off.
The chamber is so comfortable, fitted with a mattress, two pillows, and a blanket. It also features a small light for reading, air conditioning, and a telecom device for communicating with the team throughout your 60-minute session.
Medical Uses of HBOT
So, what is hyperbaric oxygen therapy used for? The NHS uses HBOT to treat a number of severe medical conditions where enhanced oxygenation is critical to recovery. Common NHS-approved uses include:
- Decompression sickness—Pressure and oxygenation reduce nitrogen gas bubbles that form in tissues, which is common in divers.
- Gas embolism—HBOT targets air bubbles in the bloodstream that can block blood vessels and lead to stroke-like symptoms.
- Carbon monoxide poisoning—HBOT accelerates the removal of carbon monoxides and restores oxygen delivery.
- Necrotising soft tissue infections—Increased oxygen prevents bacterial growth and supports tissue survival in conditions like gangrene.
- Radiation injury—Often used in patients recovering from cancer, HBOT promotes the healing of tissue damaged by radiation exposure.
Although not currently available on the NHS, private HBOT clinics in the UK increasingly use oxygen therapy to support recovery from a broader range of chronic conditions. Scientific studies on HBOT effectiveness include treatment for:
- Traumatic brain injury—HBOT can support neuroplasticity and reduce inflammation in mild-to-moderate brain injuries.
- Stroke—Enhanced oxygen can support the rehabilitation of affected areas of the brain to support stroke recovery.
- Fibromyalgia and Multiple Sclerosis—Therapy can reduce fatigue and improve energy levels.
- Diabetic foot ulcers and chronic wounds—Hyperbaric oxygen therapy for chronic wounds in the UK accelerates healing and reduces amputation risk.
- Long COVID—A growing area of interest, early HBOT and long COVID research suggests increased oxygen saturation can improve brain fog and fatigue.
Before trying any new treatment, including HBOT (Hyperbaric Oxygen Therapy), to support chronic illness, we always recommend consulting a medical professional.
HBOT for Wellness
Recent years have seen a surge in the use of hyperbaric oxygen treatments for general wellness and longevity. From faster recovery to mental clarity to overall enhanced well-being, see how HBOT could help you.
HBOT for Athletic Performance Recovery
HBOT increases oxygen delivery to injured tissue, promoting faster repair of muscles, ligaments, and bones. A game-changer for athletes and gym goers, this revolutionary treatment supports recovery from sprains, muscle tears, and fatigue. It also helps decrease swelling and inflammation, which is critical in reducing pain and preventing future injuries.
Incorporating HBOT into sports and fitness training can also give you a competitive edge. Regular treatments have been proven to boost the body’s aerobic capacity, improve endurance, and help achieve even greater performance.
HBOT for Wound Healing
By increasing oxygen availability at a cellular level, hyperbaric oxygen therapy significantly enhances the body’s natural healing abilities. When the body suffers from slow-healing wounds like surgical incisions, HBOT helps to accelerate cell regeneration of damaged tissue for faster recovery. Increased oxygen delivery also boosts the function of white blood cells, reducing the risk of infection while you heal.
HBOT for Increased Energy
The revitalising benefits of hyperbaric oxygen therapy aren’t only felt on a cellular level. The combination of increased oxygen concentration and atmospheric pressure has an invigorating effect on the mind and body, leaving you feeling alert, energised, and motivated. Indeed, HBOT is increasingly being used to treat symptoms of chronic fatigue, both by boosting energy levels and promoting better quality sleep.
HBOT for Enhanced Cognitive Function
Hyperbaric oxygen treatments saturate the blood with oxygen, enhancing oxygen delivery to the brain and supporting the formation of new blood vessels. This can have a remarkable impact on mental performance, especially with regular treatments. Coupled with the relaxing environment that allows you to unwind, our hyperbaric chamber benefits mood and relaxation levels, too, leaving you feeling clear-minded and focused.

HBOT Frequently Asked Questions
How to Prepare for a HBOT Session?
Before your HBOT session, we recommend having a light meal, but avoid alcohol, smoking, and carbonated drinks on the day of your appointment.
We suggest wearing comfortable cotton clothes – avoid synthetic fibres – and be sure to remove all metal objects, including jewellery and watches, before entering the chamber
Treatments last 60 minutes, so consider bringing a book, magazine, or your favourite podcast to keep you occupied. If not, simply relax into your treatment.
How Soon Will I See Results From HBOT?
Most clients will feel the relaxing effects of the treatment from within the chamber. If you’re undergoing HBOT for wound healing or recovery, you’ll likely see an impact and improvement within a few sessions, but we recommend regular treatments for maximum benefits.
How Long Do the Effects of Hyperbaric Oxygen Last For?
This is largely dependent on your individual goals and reasons for treatment. HBOT benefits may be felt immediately and can last for weeks, months, or even permanently. Your specialist consultant will advise you on the best number and frequency of hyperbaric oxygen therapy treatments to achieve optimal results.
Can You Exercise After Hyperbaric Oxygen Therapy?
Yes, it is safe to exercise both before and after receiving HBOT. The increased blood oxygen levels can even enhance your muscle performance and endurance, making it a great pre-workout treatment. Remember to listen to your body – while most people feel energised after HBOT, some may experience fatigue, so be sure to assess your body’s needs before engaging in physical exercise.
Do You Need a Referral for Hyperbaric Oxygen Therapy?
As we predominantly offer hyperbaric oxygen therapy for wellness and longevity, you do not need a referral to book a treatment at Re:nu. If you have received a referral from a GP, surgeon, or medical professional, we will review this with you on your initial consultation. Please remember to bring all documentation with you.
If you have any concerns about the treatment or any pre-existing conditions, consult your GP before booking.
Is it Safe to Have a HBOT Session When You Have a Cold?
If you have a cold, fever, or any respiratory infection, please inform a Re:nu team member before your appointment, as this may affect your treatment. Nasal and sinus congestion can make it difficult to equalise pressure, potentially causing discomfort during your session. It’s best to wait until you’re feeling better or consult a healthcare provider before proceeding with an HBOT session.
