A study of nearly 500,000 people has shown that smoking shortens the end fragments of chromosomes in the white blood cells of our immune systems. The length of these end fragments, called telomeres, is an indicator of how quickly we age and our cells’ ability to repair and regenerate. In her presentation to the European Respiratory Society International Congress in Milan, Italy, Dr Siyu Dai said: "Our study shows that smoking status and cigarette quantity can result in the shortening of leucocyte telomere length, which is an indicator of tissue self-repair, regeneration and ageing. In other words, smoking can accelerate the process of ageing, while quitting may considerably decrease the related risk.”
