Alzheimer’s disease can be a devastating diagnosis for both the patient and loved ones. We have all heard or experienced firsthand the challenges that memory loss creates. While there are no guaranteed ways to prevent Alzheimer’s disease, the good news is that many evidence-based lifestyle habits can significantly reduce your risk or delay its onset and one of the easiest ones is simply sitting less. While sitting itself doesn’t cause Alzheimer’s, research shows that a sedentary lifestyle is closely linked to many risk factors that increase the likelihood of cognitive decline.
Here’s how sitting too much affects your brain:
- Reduced blood flow to the brain
Physical activity improves circulation, which helps deliver oxygen and nutrients to brain cells. Sedentary behavior can limit this, potentially affecting memory and thinking skills over time.
- Increased risk of chronic diseases
Long periods of sitting raise your chances of developing diabetes, obesity, and heart disease, all of which are known risk factors for dementia and Alzheimer’s.
- Brain structure changes
Some studies (like those using MRI scans) suggest that excessive sedentary time may be linked to thinning in brain regions involved in memory, such as the medial temporal lobe.
- More inflammation, less neuroprotection
Physical activity helps reduce inflammation and boosts brain-supporting chemicals like BDNF (brain-derived neurotrophic factor), which are key for healthy neurons. Sitting for long stretches limits this protective effect.
So, can sitting less really help?
Yes, regular movement, even light activity like standing or walking, can protect brain health.
You don’t have to run marathons. Studies show benefits from:
- Taking short walking breaks every 30–60 minutes
- Getting at least 150 minutes of moderate activity per week (like brisk walking)
- Doing strength or balance training 1–2 times a week
- Staying socially and mentally active
Moving more and sitting less helps protect not just your heart and body, but also your brain. It’s one of the simplest lifestyle shifts you can make to lower your Alzheimer’s risk. It also helps boost your mood and, therefore, can leave you feeling better all around.
