72-hour study reveals significant daily variations in 13 out of 17 epigenetic clocks.
New research suggests that epigenetic clocks, which measure biological age based on genetic modifications, may not be as accurate as previously believed, due to daily fluctuations.
A study published in Ageing Cell analyzed blood samples from a single individual every three hours over a 72-hour period and found that 13 out of 17 epigenetic clocks exhibited significant daily variations, with cells appearing 5.5 years younger in the morning compared to midday.
