The Sleeping Position That Could Shorten Your Life

The position most likely to create a hidden health problem is sleeping flat on your back, especially for people with undiagnosed obstructive sleep apnoea. Back sleeping is not inherently dangerous for everyone, and it can support spinal alignment, but it allows gravity to pull the tongue and soft throat tissues backward, narrowing the airway in vulnerable sleepers.

That matters because untreated sleep apnoea repeatedly interrupts breathing and sleep throughout the night. The condition is associated with high blood pressure, heart disease, stroke, daytime exhaustion, and accidents, creating a possible route through which one habitual sleeping position could indirectly affect long-term health.
