Evidence-Based Longevity Strategies
| Strategy | Evidence |
|---|---|
| Regular strength training | Strong — preserves muscle mass, reduces frailty and fall risk |
| Aerobic exercise | Strong — cardiovascular and cognitive benefits |
| Mediterranean-style diet | Strong — reduced cardiovascular disease, possibly cognitive decline |
| Maintaining social connections | Strong — comparable impact to smoking cessation on mortality risk |
| Adequate sleep | Strong — affects nearly all health systems |
| Sense of purpose/meaning | Moderate-strong — associated with reduced mortality in observational studies |
| Not smoking | Very strong — single most impactful modifiable factor |
Muscle Mass and Strength — Often Overlooked
Sarcopenia (age-related muscle loss) significantly increases frailty, fall risk, and loss of independence. Resistance/strength training 2-3 times weekly is one of the most effective interventions to preserve function and independence into older age — more important than commonly recognised.Cognitive Health Strategies
- Regular physical exercise (strongest evidence for cognitive protection)
- Managing cardiovascular risk factors (blood pressure, cholesterol, diabetes)
- Staying socially engaged
- Continued learning and mentally stimulating activities
- Treating hearing loss promptly (linked to cognitive decline if untreated)
- Adequate, quality sleep
It's Never Too Late to StartResearch consistently shows that starting healthy habits — even strength training or exercise for the first time — provides significant benefits at any age, including into your 70s, 80s, and beyond. The benefits of starting are not limited to those who've always been active.
Are anti-ageing supplements worth taking?
Most marketed 'anti-ageing' supplements lack robust evidence for extending healthy lifespan in humans — the interventions with genuine strong evidence (exercise, diet, sleep, social connection, not smoking) are lifestyle-based, not pill-based.
What is the single most important thing for healthy ageing?
No single factor works alone, but not smoking and regular physical activity (including strength training) consistently show the strongest evidence across large population studies.
Does hearing loss really affect cognitive decline?
Yes — untreated hearing loss is associated with increased risk of cognitive decline and dementia, likely through reduced social engagement, increased cognitive load, and reduced brain stimulation. Hearing aids may help reduce this risk.
