It’s the kind of discovery that seems straight out of science fiction, but it’s happening right now. A groundbreaking study conducted by Tel Aviv University and the Shamir Medical Center in Israel has illuminated a pathway to reversing the aging process in humans, and it involves hyperbaric oxygen treatments (HBOT).

The study, published in “Aging” on November 18, 2020, reveals that HBOT can halt and even roll back the biological clock. The research focused on healthy aging adults, demonstrating that their blood cells underwent a rejuvenation process during HBOT sessions.

The Two Aging Culprits

As we age, two critical processes take place within our bodies: the shortening of telomeres (protective caps on chromosomes) and the accumulation of old and malfunctioning cells. Both of these processes are associated with aging-related illnesses. The Tel Aviv University study targeted these processes with a unique HBOT protocol.

The Remarkable Findings

The research team exposed 35 healthy individuals aged 64 or older to a series of 60 hyperbaric sessions over 90 days. Blood samples were collected before, during, and after the treatments, allowing scientists to closely monitor the effects.

The results were nothing short of astounding:

  1. Telomere Lengthening: Telomeres, which typically shrink with age, showed significant growth during the study. Depending on the cell type, telomeres increased by 20% to a remarkable 38%. Telomere elongation is considered a key factor in reversing the aging process, making this discovery groundbreaking.
  2. Senescent Cell Reduction: Senescent cells, old and dysfunctional cells that contribute to aging, saw a substantial reduction of 11% to 37%, depending on the cell type. This reduction in senescent cells is a significant step towards combating age-related health issues.

A Game-Changing Breakthrough

Professor Shai Efrati of Tel Aviv University, a pioneer in hyperbaric research and therapy, spearheaded the study. The results indicate that the aging process can indeed be reversed at the cellular level. Telomere lengthening, in particular, is considered a “Holy Grail” in aging biology, and the HBOT protocol achieved it.

Dr. Amir Hadanny, Chief Medical Research Officer of the Sagol Center for Hyperbaric Medicine and Research at the Shamir Medical Center, emphasized that only three months of HBOT led to telomere elongation rates far beyond any other known interventions or lifestyle modifications.


This groundbreaking study has opened a door to further research into the potential of HBOT for reversing the aging process. It challenges the conventional wisdom about aging and suggests that there might be more effective ways to combat age-related health issues than previously thought.

While this discovery has the potential to be a game-changer, further research and clinical trials will be needed to confirm and refine these findings. However, the prospect of hyperbaric oxygen treatments as a “fountain of youth” is now more tantalizing than ever before.

As Tel Aviv University continues to push the boundaries of scientific knowledge, we eagerly await more insights and developments that could revolutionize how we view and approach aging. Stay tuned for more exciting updates in the world of hyperbaric medicine!
