IHHT Therapy
Intermittent hypoxic-hyperoxic training for the mitochondria.
In short
IHHT (intermittent hypoxic-hyperoxic training) alternates low-oxygen and high-oxygen air through a mask. A session takes 45–60 minutes at our Sofia clinic. The controlled hypoxic stimulus trains mitochondria and improves energy metabolism, sleep quality and exercise tolerance.
What is it?
IHHT (Intermittent Hypoxic-Hyperoxic Training) simulates controlled cycles of low and high oxygen while you rest. This training "wakes up" the mitochondria — the cells' energy powerhouses — and stimulates the renewal of dysfunctional ones.
It is one of the gentlest yet deeply impactful therapies for mitochondrial health, metabolic flexibility and resilience.
IHHT Therapy is part of our comprehensive approach to longevity — a combination of diagnostics, therapies and continuous monitoring for a longer, healthier life.
