IHHT involves breathing alternating cycles of low-oxygen (hypoxic) and high-oxygen (hyperoxic) air through a specialized device. This process is thought to trigger adaptive responses similar to high-altitude training, primarily by stimulating the removal of damaged mitochondria (mitophagy) and the creation of new, healthy ones (mitochondrial biogenesis). The goal is to enhance cellular energy production, improve oxygen utilization, and increase resilience to oxidative stress, thereby supporting overall healthspan.
Verdict
A promising but developing tool for enhancing mitochondrial health and resilience.

Protocol
- Sessions typically last 40-60 minutes and are performed 2-3 times per week.
- Each cycle involves 3-7 minutes of breathing hypoxic air (9-15% oxygen) followed by 2-5 minutes of hyperoxic air (30-36% oxygen).
- A standard course consists of 10-20 sessions over several weeks.
Flags
- Contraindicated for individuals with severe hypertension, heart failure, epilepsy, or acute infections.
- Must be performed with proper equipment that monitors blood oxygen saturation (SpO2).
- Potential for mild side effects like headache, dizziness, or fatigue post-session.
- Quality and calibration of consumer-grade devices can vary significantly.
