Quitting smoking

Brain health don't smoke

If you smoke, quitting is probably the most important step you can take to protect both your heart and your brain. As well as being linked to high blood pressure, heart disease, stroke and cancer, there’s evidence that smoking increases your risk of dementia, particularly Alzheimer’s disease and vascular dementia. It’s never too late, as quitting – even in later-life – can reduce your risk significantly.

The NHS offers lots of resources to help, and it won’t take long to notice the benefits. All of the harmful carbon monoxide will be flushed out of your body just 48 hours after your last cigarette and your circulation will improve in weeks.
