Overview

• The Robert Stempel College team advises targeting 7–8 hours of solid sleep, reporting links between sleep efficiency and executive attention and between sleep fragmentation and immediate memory while noting proposed gut–inflammation mechanisms are still being explored.
• Their stress findings indicate that elevated cortisol relates to poorer memory, and that sleep quality moderates the relationship based on salivary cortisol measurements.
• Preliminary Tri-Sleep results associate higher intake of the antioxidants lycopene and beta‑cryptoxanthin with less frequent anxiety symptoms.
• Early data also tie higher‑quality diets—more fiber and protein with more fruits and vegetables and less saturated fat—to fewer nighttime awakenings and reduced sleep fragmentation.
• Physical activity is linked to lower Alzheimer’s risk, including a reported 41% reduction with about 35 minutes of moderate‑to‑vigorous exercise per week, and Tri‑Sleep data associate memory performance with waist‑to‑hip ratio.
