A Beginner’s Guide to ReOxy IHHT Therapy
An Introduction to ReOxy
Intermittent Hypoxia Hyperoxia Therapy (IHHT) is a form of oxygen efficiency training.
You relax while the system alternates between lower and higher oxygen levels, creating a controlled stimulus your body adapts to over time.
The goal isn’t to give you more oxygen.
It’s to help your body use oxygen more effectively - so energy feels steadier, recovery is smoother and you can handle more without burning out.
Reoxy is the brand of IHHT machines we are proud to have at Regen. It is the only CE-marked, medical-grade device in the world capable of delivering fully customised high and low oxygen therapy.
The Benefits
Even when training, nutrition, and sleep are in place, many people still experience:
Inconsistent energy
Slower recovery
Difficulty maintaining output
ReOxy targets that layer - how your body responds to demand and recovers from it.
Over a structured programme, many people notice:
More consistent energy across the day
Better recovery between sessions or work demands
Reduced fatigue after effort
Improved tolerance to training or stress
Alongside this, customers often report improvements in:
Sleep quality and depth
Feeling more calm and less reactive to stress
Reduced anxiety levels
Less snoring and more settled breathing overnight
These changes are often linked to how the body regulates oxygen use and the nervous system over time.
How It Works
During each session:
Oxygen levels are gently lowered, then raised
You remain at rest throughout
The system tracks your oxygen saturation (SpO₂) and heart rate
This allows each session to adjust in real time, keeping the stimulus effective but controlled.
Over repeated sessions, this supports:
Oxygen use within tissues
Circulation and delivery
Energy production
Nervous system balance
Who It’s For
Performance
If you train regularly and want to recover better, stay consistent, and handle higher workloads.
Longevity
If your focus is maintaining energy, resilience, and long-term health.
Recovery
If you’re rebuilding after stress, illness, or fatigue and need something structured but low-load.
Treatment Plan
ReOxy is delivered as a short, focused block:
10 sessions - recovery and general health
15 sessions - performance-focused
Completed within ~21 days
This structure allows your body to adapt properly, rather than relying on one-off sessions.
What Happens After
Most people don’t just feel different during the sessions — they notice changes in how they function afterwards.
Energy becomes more stable
Recovery feels easier
Sleep becomes more consistent
Daily demands feel more manageable
These effects often last for several months, and in some cases up to 9–12 months, depending on lifestyle and baseline.
Some people repeat a block later in the year.
Others maintain well without needing to.

-
Absolutely. You can try this alongside any of our therapies.
Our recommended ReOxy biostocks are:
ReOxy + NovoTHOR Red Light + PEMF = Energy & Mitochondrial Upgrade
ReOxy creates an oxygen stress that forces mitochondria to become more efficient, while red light boosts ATP production and PEMF improves cellular function. Together, this increases energy, reduces fatigue, and supports long-term cellular health.ReOxy + Sports Massage + Contrast Therapy = Circulation & Recovery
ReOxy enhances oxygen delivery, massage improves tissue flow, and contrast therapy trains blood vessels to circulate more effectively. This combination accelerates recovery, reduces soreness, and improves overall circulation.ReOxy + Infrared Sauna + Optional Cold = Detox & Cardiovascular Health
ReOxy trains oxygen efficiency while infrared sauna adds heat stress to boost circulation and sweating, with optional cold providing mild vascular stimulation. Together, this supports detoxification, heart health, and metabolic resilience. -
