Ageing, which happens over time in humans, has been biologically reversed by hyperbaric oxygen therapy, according to new research published in the journal Aging.

Scientists, led by Yafit Hachmo, from the Research and Development Unit, Shamir Medical Center, Tzrifin, Israel, turned back the human clock for 35 adults aged 64 and older by reversing two key areas of the body thought responsible for the frailty and ill-health that comes with growing older. Protective caps at the ends of chromosomes, known as telomeres, shorten, causing DNA to become damaged and cells to stop replicating as people age. At the same time, senescent cells build up in the body, preventing regeneration.

Increasing telomere length and getting rid of senescent cells is the focus of anti-ageing research, with drugs being developed to target those areas, The Telegraph reported.

The 35 patients were repeatedly given pure oxygen in a hyperbaric chamber, which increased the length of their telomeres by 20%, a feat that has never been achieved before.

Scientists said the growth may mean that the telomeres of trial participants were now as long as they had been 25 years earlier.

The therapy also reduced senescent cells by up to 37%, enabling new healthy cells to regrow. Animal studies have shown that removing senescent cells extends remaining life by more than 33%
