Boost Brain Health: Simple Lifestyle Changes Fight Dementia

A sedentary lifestyle is strongly linked to major dementia risk factors like obesity and heart disease. However, regular physical activity, particularly aerobic exercise like jogging or dancing, offers powerful protection. A 2022 study revealed that Britons who exercised regularly had a 35% lower chance of developing dementia.

Exercise delivers more nutrients to the brain and stimulates 'brain fertiliser' proteins that promote neuron growth and strengthen memory areas. Even 30 minutes of slightly breathless activity can significantly boost these essential proteins. Importantly, exercises that improve balance can help prevent falls, thus reducing the risk of head injuries.

Head injuries, even minor ones, can double or triple dementia risk by triggering abnormal protein production associated with Alzheimer's. Therefore, wearing helmets during activities like cycling is vital. Breathing polluted air also elevates dementia risk by 10% due to PM2.5 particles that can reach the brain.

Social interaction plays a key role, with loneliness increasing dementia risk by 60%. Engaging in varied social activities stimulates different brain networks and helps reduce anxiety and depression. Furthermore, quitting smoking can reduce dementia risk to non-smoker levels within two years.

Challenging the brain with new learning experiences, rather than repetitive tasks, improves brain cell connections and resilience. Finally, moderating alcohol intake is essential, as excessive drinking damages brain cells and blood vessels, contributing to stroke and heart disease, both dementia risk factors.
