😴 How Much Sleep Do You Really Need? Nature Finds a 6–8 Hour Longevity Sweet Spot

A major Nature study examining 23 biological ageing clocks across the brain and body found a striking U-shaped relationship with sleep: both too little and too much were associated with faster ageing, disease and mortality. The biological sweet spots clustered around 6.4–7.8 hours. So sleep well—but perhaps don't sleep through your life.

Futuristic illustration of an unconscious human brain processing language and predicting words during anesthesia, with glowing neural pathways and AI-like thought patterns visible above a sleeping patient.

🧠 Even the Unconscious Brain Can Learn, Predict, and Process Language

Scientists discovered that the brain remains surprisingly active under anesthesia, continuing to process language and predict words even when conscious awareness disappears.
