Scientists claim to have successfully reversed the biological aging process in a group of elderly adults.

In a first of a kind study, researchers from Tel Aviv University and the Shamir Medical Center used a form of oxygen therapy to reverse two key indicators of biological aging: Telomere length and senescent cells accumulation.

As the human body gets older, it experiences the shortening of telomeres – the protective caps found at the end of chromosomes – and an increase in old, malfunctioning senescent cells.

A clinical trial involving 35 adults over the age of 64 sought to understand whether a method called Hyperbaric Oxygen Therapy could prevent the deterioration of these two hallmarks of the aging process.
