Don't play around with altitude.
Altitude training is a powerful tool for performance and longevity – but there are no shortcuts without risk. The market is full of dubious offers claiming you can easily simulate altitudes of 6,500 m or more at home. This is not just unprofessional; it's life-threatening.
The real danger in altitude training is often not suffocation, but the destruction of your health through physiological overexertion.
A tragic example
The tragic case of Norwegian biathlete Sivert Guttorm Bakken highlights how important it is to use artificial altitude responsibly. The 27-year-old was found lifeless in his hotel room. It is suspected that using an altitude mask to simulate an extreme altitude of 7,000 meters may have contributed to the fatal outcome.

The 4 critical risks of incorrect use
"Burning out" (Autonomic Burnout)
Altitude is a massive stressor. If you start too aggressively (e.g., sleeping directly at 3,500 m), you'll blow out your autonomic nervous system. The result: your resting heart rate spikes, your sleep is ruined, and you end up in a burnout hole instead of increasing your performance.
Blood thickening (Thrombosis risk)
Due to the lack of oxygen, your body produces more red blood cells. Since you also lose a lot of water through breathing in the dry mountain air, your blood becomes thick. Without professional monitoring and correct hydration, the risk of thrombosis, embolism, or stroke increases massively.
Altitude sickness in the bedroom
If the altitude is increased too quickly, you'll develop real symptoms of altitude sickness: severe headaches, nausea, and dizziness. With improper handling, even life-threatening pulmonary or cerebral edema can occur in extreme ranges.
CO₂ poisoning (The hidden risk in the tent)
In closed tents, rebreathing your own carbon dioxide (CO₂) is the greatest danger – especially with two people in a tent that's too small or when using so-called head tents. Poor air exchange can trigger extreme headaches or, in the worst case, lead to loss of consciousness.
My approach: Safety through expertise
I advise you individually based on your health check and blood values. We plan your acclimatization so that metabolic adaptation and recovery go hand in hand.
Instead of experimenting with unrealistic altitudes and dangerous quick fixes, you rely on a professional, controlled, and safe strategy.
