NON-SMOKERS who live with or spend time with smokers are damaging their memory, according to research.
The Northumbria University study is the first to explore the relationship between second- hand smoke and memory problems.
Dr Tom Heffernan and Dr Terence O’Neil compared smokers with two groups of non-smokers – those regularly exposed to second-hand smoke and those who were not.
Non-smokers exposed to second-hand smoke forgot nearly 20 per cent more in memory tests than those not exposed.
However, smokers forgot 30 per cent more than those not exposed to second-hand smoking.
