Markers of Cellular Aging Improve During Insight Meditation Retreat

By Anahita Hamidi

Telomeres are repetitive nucleotide sequences that act as protective “caps” at the end of DNA strands. As cells age, either as a function of time or as a result of stress and poor health, telomeres tend to shorten. As such, telomere length can be used as a crude biological marker of health and well-being.

A recent study by researchers at the University of California Davis, Center for Mind and Brain, measured changes in telomere length, telomerase (the enzyme which replenishes telomeres), and telomere-regulating genes in a group of individuals who participated in a month-long Insight meditation retreat.
