# HBOT: What Science Says About Hyperbaric Oxygen Therapy

> Hyperbaric oxygen therapy is no longer a fringe phenomenon. What is really behind it and why are elite athletes and longevity researchers increasingly turning to it?

Breathing 100% pure oxygen in a pressure chamber sounds unusual at first glance. But the science behind hyperbaric oxygen therapy is solid, well documented and increasingly relevant for longevity and performance.

## What happens physiologically during HBOT

During HBOT, air pressure is increased to 1.3 to 2.0 ATA. Under normal pressure, oxygen is transported almost exclusively bound to hemoglobin. Under elevated pressure, oxygen dissolves directly into the blood plasma, a fundamental difference. This enables up to 14 times higher oxygen delivery to tissues, reaches areas with poor blood flow and stimulates repair processes at the cellular level.

## What the research concretely shows

A 2020 study from Tel Aviv University (Efrati et al.) showed, after repeated HBOT sessions over 60 days: **+20% telomere length** and **a 37% reduction in senescent cells** in healthy older adults. These are the strongest anti-aging effects ever measured for a non-pharmacological intervention.

**Neovascularization:** HBOT stimulates the formation of new blood vessels through upregulation of VEGF, relevant for recovery after intense training or injuries. **Neuroplasticity:** Several controlled studies show improved cognitive function in long COVID and age-related cognitive decline. **Anti-inflammatory action:** HBOT modulates inflammatory cytokines and reduces oxidative stress at the cellular level. **Stem cell mobilization:** Recent research shows up to 800% increased stem cell mobilization from the bone marrow.

## Who HBOT is relevant for

**High performers and executives** benefit from better cognitive clarity and faster recovery after high-stress periods. The brain consumes 20% of the body's total energy; when cerebral mitochondria are better supplied, you think more clearly and make better decisions. **Athletes** use HBOT for shorter recovery times and improved VO2max. **Longevity-oriented individuals** value the proven telomere-protective effects and the reduction of senescent cells.

A session lasts 60-90 minutes. For measurable long-term effects, 20-40 sessions are recommended. The portable home version (1.3-1.5 ATA) allows regular use without visiting a studio, from CHF 450 per month.

## HBOT in combination

HBOT delivers its greatest benefit in combination with other longevity interventions. Combined with IHHT, you address both mitochondrial regeneration and systemic oxygen supply, a synergistic effect. Red light therapy after HBOT uses the activated mitochondria for additional ATP production.

## Frequently asked questions

**Is HBOT safe for home use?**
Portable chambers up to 1.5 ATA are considered very safe. CE-certified devices come with personal instruction. If you have pre-existing conditions, prior medical consultation is recommended.

**How quickly are the first effects noticeable?**
Many people report better sleep and more energy after 5-10 sessions. Measurable anti-aging biomarkers appear after 20+ sessions. The effect is cumulative.

**Can HBOT be combined with other therapies?**
Yes, it works synergistically with IHHT, red light therapy and hydrogen therapy.
