1. Move Your Body — Often
If there is one habit with the strongest support in cognitive-aging research, it is regular aerobic exercise. Activities like brisk walking, swimming, cycling, and dancing support cardiovascular health, brain circulation, mood, and sleep — all of which underpin cognitive performance. Aim for at least 150 minutes of moderate aerobic activity per week, plus two days of strength training.
2. Sleep Like It Matters (Because It Does)
During sleep, your brain consolidates memories, clears metabolic waste, and resets emotional regulation. 7–9 hours of consistent, high-quality sleep is one of the most important things you can do for long-term cognitive health. More on sleep and memory →
3. Eat a Brain-Supportive Diet
The dietary patterns most consistently associated with healthy cognitive aging share a common shape: lots of vegetables, fruits, fatty fish, nuts, legumes, olive oil, and whole grains — with limited refined sugar and processed foods. The Mediterranean and MIND diets are the best-studied examples. Brain-healthy diet guide →
4. Stay Socially Connected
Social engagement is consistently associated with cognitive resilience. Conversation, group activities, family connection, and community involvement keep multiple cognitive systems active — language, memory, social reasoning, emotional regulation.
5. Keep Learning
Take up new skills. Read challenging material. Learn languages, instruments, crafts. Cognitive engagement helps build what researchers call "cognitive reserve" — the brain's capacity to absorb challenges and still function well.
6. Manage Stress
Decades of chronic stress affect the parts of the brain most involved in memory. Build daily stress-management practices: breathing, time in nature, mindfulness, quality rest, and supportive relationships.
7. Mind Your Vascular Health
Healthy blood pressure, cholesterol, and blood sugar are not just heart matters. Vascular health is brain health. Work with your healthcare provider to keep these in the healthy range.
8. Consider Nutritional Support
Several ingredients have been studied for their support of cognitive function in healthy adults:
