What if you could get the benefits of training at high altitude without leaving your chair? IHHT (Intermittent Hypoxic-Hyperoxic Training) is a non-invasive therapy that gently cycles your breathing between low-oxygen air (hypoxia) and oxygen-rich air (hyperoxia) in carefully controlled intervals. At Montis, we position IHHT as your body's Systemic Shield — the therapy that trains your cells to become stronger, more resilient, and more efficient at producing energy.
Why Does It Matter?
Every cell in your body runs on energy produced by mitochondria — your cellular power stations. Over time, through stress, poor nutrition, illness, and ageing, mitochondria become worn out and inefficient. IHHT is a Battery Replacement Programme — it forces the body to discard old, inefficient mitochondria and manufacture brand-new, high-performance ones.
Breathing life into wellness.
How It Works
01
Mitochondrial Renewal (Mitophagy)
The controlled hypoxic phase triggers the body's internal quality control system, identifying and clearing out old, tired mitochondria and replacing them with new, high-performance ones. This process is called mitophagy, one of the most powerful anti-ageing mechanisms the body possesses.
02
Vascular Adaptation
IHHT improves how efficiently your blood carries and delivers oxygen throughout the body, enhancing cardiovascular health, supporting the inner lining of your blood vessels, and reducing the workload on your heart.
03
Cellular Energy Production (ATP Boost)
By training your cells to operate under controlled oxygen variation, IHHT dramatically improves your mitochondria's ability to produce ATP — the body's primary energy currency. More ATP means more stamina, sharper thinking, and faster recovery.
The Session — What to Expect
Each Montis IHHT session follows a precise, medically designed protocol: Total Duration: 40 minutes · Cycles: 5 cycles per session · Hypoxic Phase: 3 minutes of controlled low oxygen · Hyperoxic Phase: 5 minutes of oxygen-rich recovery. You recline comfortably throughout. Every session is monitored by our medical team. Most clients describe the experience as deeply relaxing, almost meditative.

Frequently Asked Questions
Will I feel out of breath?
+
No. The oxygen reduction is very controlled and gradual. You may feel a slight mountain air sensation, but most clients find the session deeply relaxing and even meditative.
Is it like a workout?
+
Biologically, yes — it is a workout for your cells. Physically, no. You are simply reclining and breathing through a mask. You get all the benefits of altitude training without any physical exertion or sweat.
Why do I need this before Cellular Therapy?
+
IHHT ensures your existing cellular environment is strong, optimised, and ready to support new regenerative growth, maximising the results of your Cellular Therapy.
Is it safe?
+
Yes. Every session at Montis is monitored by our medical team, and suitability is always confirmed through a medical assessment before your first session.
Build Your Shield. Power Your Cells. Protect Your Future.
At Montis, IHHT is the therapy that turns your cells from passengers into performers, building the biological resilience your body needs to thrive, recover, and respond to everything that follows.
