Sleeping Less and Living Shorter
Sleep duration is an independent, quantifiable, and modifiable predictor of premature death, with an effect size comparable to several established behavioral risk factors.

Why the Timing of a Nap Matters More Than the Nap Itself
Short, consistent, early-afternoon naps are associated with more favorable cognitive trajectories, while long, morning, or highly irregular napping patterns track with worse outcomes.
-
When the Day Is Too Dim the Brain Forgets Faster
Daytime light exposure is not a peripheral lifestyle detail but a measurable, modifiable input into the biological machinery that protects the aging brain.
-
When Sleep Loses Its Rhythm the Brain Ages Faster
Sleep regularity, not merely duration, must be positioned as a first-order target in longevity medicine and preventive neurology.
-
When Fragmented Sleep Makes the Heart Forget to Rest
Fragmented sleep, even in the absence of total deprivation, disrupts the complex neuroendocrine and metabolic processes that sustain cardiovascular resilience and systemic repair.
-
Obstructive Sleep Apnea as the Fourth Pillar of Metabolic Syndrome and Accelerated Aging
Obstructive sleep apnea functions as an upstream driver of metabolic syndrome components and a potent accelerator of biological aging through intermittent hypoxia.

Chrononutrition and the Temporal Dimension of Metabolic Health Across the Aging Lifespan
Aligning food intake with endogenous circadian rhythms improves insulin sensitivity, lipid handling, and longevity pathways independently of caloric restriction, reframing meal timing as a therapeutic target.

Sunlight, Circadian Rhythms and Glucose Metabolism in Modern Indoor Lifestyles
Reduced natural light and irregular schedules disrupt circadian organization, altering insulin sensitivity, postprandial glucose profiles, and long‑term cardiometabolic risk in continuous‑glucose‑monitoring and longevity contexts.
