A new Australian study has revealed that vigorous physical activity may help reduce the risk of developing dementia by lowering levels of a key blood protein linked to brain inflammation.
Researchers from the University of Tasmania studied over 1,000 participants and found that those who regularly exercised at a high intensity, whether running, swimming, or any activity that gets you “puffing and panting”, had lower levels of GFAP, a protein associated with brain degeneration.
The study showed that people who engaged in more vigorous exercise had lower GFAP levels, suggesting better brain health and reduced inflammation. The higher the intensity of the activity, the stronger the reduction in GFAP, indicating that it’s not just about doing some exercise, more strenuous forms appear to offer greater benefits.
Importantly, the protective effect of exercise was also observed in individuals who carried the ApoE4 gene, a known risk factor for Alzheimer’s disease. While the effect was slightly less pronounced in this group, the findings highlight that lifestyle choices, such as regular vigorous exercise, still play a crucial role in supporting brain health, even when genetics may increase risk.
What You Can Do
Incorporating vigorous activity into your routine can make a real difference. You don’t need to run marathons. Internal runs, fast swim laps, or short intense workouts are all excellent options. The key is consistency over time; long-term habits built over months and years are what truly benefit your brain.
Mixing up your exercise is also important. If your usual routine is moderate activity like walking, light jogging, or yoga, try blending in higher-intensity sessions such as cross-training, swimming, or paddling.
And while genetics can play a role, they are not destiny. Exercise still offers strong protective benefits regardless. When combined with other lifestyle essentials, such as, good sleep, social connection, healthy blood pressure and cholesterol, avoiding smoking, and protecting your hearing, the impact on your brain health is even greater.
Your workouts today are an investment in a sharper, healthier future.
