Smokers will look much older than they actually are. This “smokers face” condition is one among the many negatives of heavy smoking or tobacco usage, according to a study by a group of researchers at the University of Bristol in England.
According to the study that was published in PLOS genetics journal says that some people carry one or two copies of a genetic variant which is associated with heavier tobacco use. Apart from affecting lung health, the researchers have now found that appearance can also get changed with heavy use of tobacco.
For the study, the researchers used a unique combination of two data analysis approaches. They selected people from the UK Biobank. The people chosen were grouped into two – one group who had never smoked and the other group had people who at present smoked and also former smokers.
The researchers had used two types of analysis as said. One of them was “Mendelian randomization” that is used to look at the genetic variations. In t5he other methodology, they compared genetic associations in smokers and non-smokers The study says that present smoker who smokes five cigarettes a day for 12 years or a former smoker who had smoked the same numbers for 21 years and stopped ten years ago will have an older face than those who have never smoked in their life time.
