Do you often feel sluggish, drained of energy, and exhausted despite getting enough sleep? When your morning coffee no longer works and your concentration drops rapidly throughout the day, the root cause is often hidden deep within our bodies: in our cells. More specifically, in the mitochondria.
The so-called mitochondrial training, known as IHHT (Intermittent Hypoxic-Hyperoxic Training), starts exactly here. It is one of the most modern and effective methods in functional medicine to regenerate the body at the cellular level and gain sustainable new energy.
What are mitochondria and why are they so important?
Imagine your body as a large city. For everything in this city to run smoothly, it needs power. This power is supplied by the mitochondria – they are the tiny but extremely powerful power plants of our cells.
There are hundreds of these power plants in almost every one of our body cells. Their main task is to produce the universal cellular energy ATP (adenosine triphosphate) from the food we eat and the oxygen we breathe. We need this energy for:
- Concentration and cognitive performance
- Muscle work and vitality
- A functioning immune system
- Regeneration and cell renewal
The connection: When the cellular power plants go on strike (Symptoms)
Over time, due to stress, poor diet, or chronic inflammation, mitochondria become damaged. They produce less energy and emit more free radicals. The result is a condition we call mitochondriopathy.

Typical signs of exhausted cellular power plants include:
- Chronic fatigue
- "Brain fog" (concentration issues and mental cloudiness)
- Long recovery times after physical exertion
- Increased susceptibility to infections
- Sleep disturbances despite severe exhaustion
How does IHHT work as mitochondrial training?
The IHHT method simulates altitude training, as known from competitive sports – but completely relaxed while lying down. Through a breathing mask, oxygen-poor air (hypoxia) and oxygen-rich air (hyperoxia) are supplied in alternating intervals. This targeted “oxygen stress” causes a fascinating reaction in the body.
Cellular Anti-Aging: Sorting out old mitochondria
The brief lack of oxygen during the hypoxia phase acts like a fitness program for the cells. Damaged, “old” mitochondria cannot withstand this stimulus and are specifically broken down by the body. You can think of it as a cellular garbage collection that makes room for something new.
Stimulating new energy production
In the subsequent phase with high oxygen levels (hyperoxia), the multiplication of healthy, powerful mitochondria is massively stimulated. The result is a rejuvenated cell pool that can efficiently produce ATP again. You will feel fitter, more alert, and more resilient.
Who is cell training particularly suitable for?
Mitochondrial training at the Vitamin Institute is a versatile form of therapy. People who particularly benefit include those with:
- Chronic Fatigue Syndrome (CFS)
- Long COVID or post-vaccine symptoms
- Burnout or high stress levels in everyday life
- Competitive sports goals to optimize recovery
- The desire for healthy aging (longevity)
The Process: What an IHHT session at the Vitamin Institute looks like
A typical session lasts 45 to 50 minutes. You lie relaxed on a comfortable lounger. While you breathe the controlled air through the mask, we continuously monitor your vital signs (oxygen saturation and pulse) via a finger clip. Many of our patients use the time for deep relaxation or a short nap. It is completely painless and safe.

Sessions 1–5
We review your medical history, clarify contraindications, and define your individual therapy goal – whether regeneration, exhaustion, prevention, or performance enhancement.

Sessions 6–10
Exercise tolerance increases measurably. Short walks or light everyday tasks become possible again without triggering the typical crash the following day. This step – from “every little thing knocks me out” to “I can do small things again” – is, for most patients, the first noticeable improvement in quality of life.

From session 8 onwards
Brain fog and concentration gradually improve. This is the feedback we hear most often – and, from experience, also the improvement patients have been waiting for the most.
Important: not everyone responds in the same way. Duration of illness, severity of mitochondrial dysfunction, and baseline micronutrient deficiencies all influence the result. We do not make blanket promises – we continuously adapt the protocol to the actual development.
T. M., Munich, 41 years old (patient, Long COVID after infection in winter 2023)
“After six months of Long COVID, I was no longer able to work. After ten IHHT sessions at the Vitamin Institute, I finally feel at home in my body again. The brain fog is gone, and my resilience is slowly returning.”
Conclusion: Back to more vitality in everyday life
Mitochondrial training (IHHT) for chronic exhaustion and stress intervenes at a point that many classic recovery approaches overlook: the disrupted energy production at the cellular level. The scientific basis for hypoxia training is solid, and clinical practice shows clear improvements in cellular resilience in cases of energy deficiency and burnout symptoms.
What theoretical models cannot always depict, our daily practice shows: IHHT works best when it is individually dosed, accompanied by laboratory diagnostics, and combined with targeted micronutrient therapy. Anyone who starts cell training without this medical foundation leaves significant potential untapped.
If you suffer from persistent exhaustion, the consequences of stress, a noticeable drop in performance, or ME/CFS and would like to know whether and how IHHT is suitable for you, schedule an initial consultation at the Vitamin Institute Munich. We first evaluate the relevant laboratory findings and develop a therapy concept individually tailored to your mitochondria on this basis.
FAQ (Frequently Asked Questions)
For noticeable and lasting effects, we recommend a course of 10 to 15 sessions, ideally twice a week.
The therapy is very safe. Occasionally, slight fatigue may occur after the first few sessions, which is a sign that the body has begun the regeneration processes.
No, just come in comfortable clothing. It is recommended to drink plenty of water before and after the session.
