Sedentary lifestyle linked to rising dementia risk, experts warn

Dementia is increasingly challenging worldwide, and the number of people affected by this condition is growing. While factors such as age or genetics are beyond our control, a sedentary lifestyle is something we can address. A lack of physical activity negatively affects the brain, increasing the risk of dementia.

About one-third of the global population spends most of the day sitting. Unfortunately, this doesn't bode well for our health. Sedentary work, the absence of any form of physical activity, excessive screen time, and poor dietary choices will eventually impact our well-being.

Neurologists from eatingwell.com emphasize that a sedentary lifestyle can lead to reduced blood flow to the brain, disrupting the delivery of oxygen and nutrients. Regular physical activity improves blood flow, supporting brain function. Long-term inactivity can also lead to brain atrophy, especially in the hippocampus, the area responsible for memory.

A sedentary lifestyle also promotes chronic inflammation, which is associated with an increased risk of many diseases, including dementia. Experts recommend regular physical activity to improve brain health and help manage blood pressure, cholesterol, and blood sugar levels.

What can you do to reduce your risk of dementia? Firstly, take breaks if you spend your work hours sitting. Every one or two hours, stand up and do some jumping jacks, jog in place, or take a short walk. Avoid stimulants, engage your mind with social interactions and logic games. Visit your doctor regularly for check-ups.

Consider your diet - do you have enough omega-3-rich foods? Include vegetables, fruits, whole grains, nuts, seeds, and fish such as mackerel or salmon in your meals.
