Senior Wellness Fundamentals: What Actually Matters
Movement, nutrition, sleep and social connection — the four pillars of healthy aging, ranked by evidence.

After age 65, the wellness interventions with the largest measured effect are unsexy: regular movement, adequate protein, consistent sleep and meaningful social contact. Everything else is rounding error.
Movement should be daily and varied. The strongest geriatric outcomes come from a mix of walking, resistance training twice weekly, and balance work — the last of which is the single best fall-prevention lever.
Protein intake is the most under-prioritized variable. Sarcopenia accelerates after 70 and is largely preventable with 1.2–1.6 g of protein per kg body weight daily, spread across meals.
Sleep architecture changes with age but total need does not. Persistent sleep complaints deserve evaluation — sleep apnea is dramatically underdiagnosed in older adults and treatable.
Social connection is a clinical variable. Loneliness is associated with mortality at magnitudes comparable to smoking. Structured contact — clubs, faith communities, scheduled family time — outperforms incidental contact.
The fall-prevention guide and medication-management guide in this cluster operationalize these fundamentals.
