A groundbreaking study analyzing health data from over 500,000 adults has pinpointed the ideal nightly sleep duration for slowing biological aging: between 6.4 and 7.8 hours. The research, led by radiologist Junhao Wen and his team, utilized "Ageing Clocks" to assess how sleep patterns influence organ-specific aging rates.

The Science Behind Aging Clocks

The study focused on 17 organ systems, including the heart, lungs, and immune system, using biological markers to track aging. "Eine fruchtbare Idee, denn bisher wurde das Konzept der 'Alterungs-Uhr' fast immer nur auf den Körper in seiner Gesamtheit angewendet, obwohl bekannt ist, dass unsere Organe in unterschiedlichen Geschwindigkeiten altern," noted the researchers. This approach allowed them to identify how sleep duration affects different parts of the body independently.
