5. Don’t smoke
Cigarette smoking is harmful to heart health, and the chemicals found in cigarettes trigger inflammation and vascular changes in the brain. They can also trigger oxidative stress, in which chemicals called free radicals can cause damage to our cells. These processes may contribute to the development of dementia.
The good news is that smoking rates in Australia have dropped from 28% to 16% since 2001.
As dementia risk is higher in current smokers compared with past smokers and non-smokers, this provides yet another incentive to quit once and for all.
