The effects of pollution on the environment are well documented, but we tend to hear less about the damaging consequences of air pollution on physical health and cognition, and particularly on the ageing brain. That said, there have been some interesting studies on this topic published in recent years.

Unquestionably, high levels of air pollution can cause an increased risk of heart attacks, respiratory problems and eye and nasal irritation. Nitrogen dioxide levels alone contributes to the early deaths of 40,000 Brits every year. But what about low levels? And what can we do to look after ourselves?

In this blog, we’ll look more closely at the biological impact of air pollution and suggest means of countering such effects.
