You might have expected the degeneration of your brain to go hand-in-hand with the aging process of your physical body, but science has spoken, backing the fact that the practice of meditation preserves our brains cognitive function and therefore adding years to our biological clock.
At each end of our DNA cell strands are protective caps called Telomeres. The longer the telomere, the more times a cell can divide and refresh. The shorter your telomeres get, the shorter your lifespan becomes, which gives your cells a more significant susceptibility to dying off but is a big part of the natural physiological aging process.
One factor has stood out in all major studies when it comes to what accelerates the shortening of our telomeres: chronic environmental stress and perceived stress induces premature aging.
