Asthma could be passed down through generations

Close to 18.9 million American adults are currently living with asthma, while more than 7 million children are also inflicted with the condition, the Centers for Disease Control and Prevention reports. Even though certain factors like air pollution have been found to play a role in the development of asthma, a new trial finds that grandmothers' smoking habits could cause their grandchildren's condition.

The study, published in the journal Review of Obstetrics & Gynecology, discovered this after reviewing the effects nicotine had on pregnant rats. During trials, scientists found rats who were given nicotine while pregnant gave birth to asthmatic babies. These baby mice then had babies of their own when they reached adulthood, and even though they did not ingest nicotine prior to giving birth, many of their babies were born with asthma. 

Such findings suggest that the effects of nicotine can leave "heritable epigenetic marks on the genome, which make future offspring more susceptible to respiratory conditions," according to Science Daily.

Even though more research needs to be conducted to verify these results, parents can still help their children who suffer from asthma now. Ensuring a child has an inhaler to deal with triggers and installing air purifiers like the Airgle PurePal CleanRoom AG900 in the home can ensure youngsters breathe only fresh air while relaxing with family.
