Scientists claim they have successfully reversed the human ageing process in a group of elderly adults in a breakthrough study.
Oxygen treatment altered the elderly people’s bodies at a cellular level to how they were 25 years earlier, researchers claimed.
In a unique study, scientists used oxygen therapy to reverse two key indicators of biological ageing – telomere shortening and an accumulation of malfunctioning senescent cells.
As humans age, their bodies experience the shortening of telomeres – the protective caps on chromosomes – which leads to illnesses including cancer, Alzheimer’s and Parkinson’s.
Senescent cells, or so-called zombie cells, prevent regeneration as they build up in the body over time.
The study used a method called Hyperbaric Oxygen Therapy in an effort to prevent the deterioration of these two characteristics of the ageing process.
In the study, published in the journal Ageing, 35 healthy adults aged 64 and older were placed in pressurised oxygen chambers in Israel and breathed in pure oxygen through a mask.
The sessions lasted for 90 minutes each and took place five days a week for three months.
