“Telomeres function as a protective buffer against DNA loss during replication and DNA damage caused by inflammation, reactive oxygen species, and other chemical compounds. Telomeres get shorter with age and telomere length is a biological marker for age.”

“Telomeres are often compared to the plastic tips on the end of shoelaces (aiglets) because telomeres protect chromosomes from fraying on the ends. Both acute and chronic stress increase inflammation, which can cause chromosomes to become frayed when telomeres are short.”

“Protection against telomere shortening is provided by activation of the enzymes telomerase and glutathione peroxidase. Findings from a new study suggest that cognitive behavior therapy reduces telomere attrition by activating these protective mechanisms.”

“Hallmarks it leaves alone — DNA mutations, telomere shortening, senescent cells, accumulated protein aggregates, damaged extracellular matrix, tissue-level architectural damage. These belong more to the "damage repair" side of aging rather than the "information reset" side.”

“The study involved 35 older adults who underwent 60 hyperbaric oxygen therapy treatments over three months. Using blood samples the participants provided before, during, and after the intervention, researchers assessed the participants' immune cell telomere length and senescence.”

“These findings suggest that lifelong training does more than strengthen muscles or endurance; it may also preserve cellular health. By keeping the body's stress and repair systems in better balance, athletes could slow the natural shortening of telomeres that accompanies aging.”

“DNA damage is known to accelerate telomere shortening. This randomized controlled trial showed that coffee lowers DNA damage and that would be expected to potentially slow telomere attrition.”

“They get shorter every year and are a biological marker for aging. Exercise is one of the most robust ways to slow telomere attrition and someone that is very physically active may have a biological age that is even 10 years younger than their chronological age.”
