The fountain of youth can be made of air, not water.
Scientists claim to have successfully reversed the aging process in older people with “oxygen therapy” in a unique study.
Tel Aviv University researchers have used hyperbaric oxygen chambers to target specific cells and DNA linked to shorter lifespans – and have found the “holy grail” of staying young, statement says press release on the discovery.
During the study, researchers examined whether therapy – which involves breathing pure oxygen in a pressurized environment – could reverse the effects of aging in 35 people over 64, according to the study, published Wednesday in the journal Aging.
They placed elderly participants in the chamber for 90 minutes a day, five days a week for three months and studied its impact on senescent cells, which are associated with tissue and organ damage. They also measured the length of each person’s telomere, a molecule linked to premature cellular aging.
Remarkably, the scientists found that participants’ telomeres grew by an average of 20% in length while their senescent cells shrank to 37% by the end of the trial – the equivalent of 25 years. younger.
“The significant improvement in telomere length shown … provides the scientific community with a new basis for understanding that aging can, indeed, be targeted and reversed at the basic cellular and biological level,” said the co-author of the Shai Efrati study. “Since telomere shortening is considered the ‘holy grail’ of the biology of aging.”
During the sessions, participants did not change their lifestyle, diet or medications, which in the past have been shown to impact a person’s biological age.
Scientists, including doctors at Shamir Medical Center, believe the pressurized chamber triggered brief oxygen shortages, which caused cell regeneration.
“So far, interventions such as lifestyle modifications and strenuous exercise have been shown to have an inhibitory effect on the expected shortening of telomere length,” said Dr Amir Hadanny, co-author of the ‘study.
“What’s remarkable about our study is that in just three months of therapy, we were able to achieve such significant telomere lengthening – at rates far superior to any intervention or lifestyle modification today. available.
In 2016, experts found they could stop aging in mice by giving them drugs that kill senescent cells.
