- Which preventive screenings actually matter?
- Blood pressure, lipid panel, colorectal cancer screening starting at 45, cervical and breast cancer screening per USPSTF, and immunizations. Most other 'wellness' panels have limited yield.
- How much sleep do adults need?
- Most adults need 7–9 hours. Consistency of timing matters as much as total duration — irregular schedules independently predict worse cardiometabolic markers.
- Is daily multivitamin use worthwhile?
- For most non-deficient adults, evidence is weak. Targeted supplementation (vitamin D, B12 if vegan, iron if menstruating with low stores) is better-supported.
- What's the single most effective stress intervention?
- Regular aerobic exercise is the most-studied intervention with broad effect across mood, sleep and cognitive function — outperforming most apps and supplements.
