“Too few or too many hours of sleep may speed up ageing in the brain, heart, lungs, and immune system and be linked to several diseases, according to a new study.”
CORROBORATED
Multiple web search results confirm that both short and long sleep durations are linked to accelerated biological aging across multiple organ systems, including lungs and the immune system.

web search NEUTRAL — Short sleep’s link to depression appeared largely direct, not passing through biological aging of organs as a go-between. Long sleep worked differently: its connection to depression appeared to run su…

“People who regularly slept for fewer than six hours or more than eight hours tended to show signs of faster ageing across the body.”
CORROBORATED
Two independent web sources explicitly state that sleeping fewer than six hours or more than eight hours is linked to faster biological aging.

web search NEUTRAL — Though most aging clocks measure aging across the whole body, organs age at different rates—a fact well-known to women facing ticking biological clocks due to fast-aging ovaries.

“The team used what they call “biological ageing clocks,” tools that estimate how many years a person ages faster or slower than their chronological age, using machine learning, based on biological data such as brain scans, blood proteins and chemical markers in the body.”
SINGLE SOURCE
The provided evidence for this specific claim consists of irrelevant search results for AI study tools (Studley AI, Study.com, StudyFetch) and does not describe the 'biological aging clocks' methodology.
