In this episode of The Science of Age-less Living, Dr. Ethan argues that aging is not primarily about accumulated damage (oxidative stress, inflammation, telomere shortening), but a loss of timing and synchronization in the body’s biological clocks.

The master clock (SCN in the brain) and peripheral clocks in organs coordinate hormones, gene expression, metabolism, repair, and immunity in precise rhythms—strong and harmonious in youth, but increasingly damped and desynchronized with age. This breakdown causes inefficient repair, unchecked inflammation, and rapid functional decline, explaining why organs age at different rates and why short-term sleep loss accelerates aging markers faster than expected.

Sleep is highlighted as the key synchronizer (via melatonin, growth hormone pulses, etc.), while continuous, non-rhythmic int ...
