“Both sleep patterns carried a higher risk of death from any cause, though, as short sleepers had a 50% higher risk, while long sleepers had a 40% chance”
SINGLE SOURCE
While some sources discuss mortality risks for short/long sleepers, the specific percentages (50% for short, 40% for long) are not corroborated across the provided evidence. One source mentions a 30% higher risk for short sleepers, which contradicts the 50% claim, but the overall specific pairing of 50%/40% is not found in multiple sources.
