Sleep Quality Matters More Than Quantity

Is sleep quality as important as duration?

Yes. Poor sleep quality raises mortality risk even when total hours are adequate.

Explanation

Fragmented sleep, insomnia, and sleep apnea disrupt restorative stages of sleep, undermining health despite sufficient duration. Poor sleep quality is linked with hypertension, obesity, insulin resistance, and higher risk of cardiovascular disease.

Improving sleep quality — through treating apnea, managing stress, or improving sleep hygiene — restores restorative slow-wave and REM sleep, supporting metabolic and neurological resilience. Sleep quality predicts longevity independently of sleep duration.

Practical Emphasis: Evaluate not just how long you sleep, but whether you feel refreshed upon waking. Address sleep disturbances proactively with medical evaluation when needed.

Takeaway (Action Tip)

Optimize sleep quality and consistency, not just hours.
