Asthma is an inflammatory condition of the airways in which the airways get narrowed, which may lead to cough, wheezing, shortness of breath (breathing difficulty) and chest tightness.
Asthma can be caused by various reasons, such as genetics and environmental factors. Environmental factors include allergies, weak immune system, smoking, occupation, etc.
We know that people with a family history of asthma are more likely to develop asthma.
A recent study shows that children are more likely to get asthma if either of their parents were smokers or exposed to secondhand smoke (passive smokers). The study also stated that smoking can cause respiratory issues over two generations and named the phenomena transgenerational effects.
The researchers found that the risk of non-allergic asthma in children increases by 59% if their fathers were exposed to secondhand or passive smoking in childhood.
The researchers found that children were at a 59% greater risk of developing non-allergic asthma if their fathers were exposed to secondhand or passive smoking in childhood compared to those fathers who were not exposed.
The risk increases by 72% when children whose fathers were exposed to passive smoking and later started smoking.
Smoking is not just harmful to smokers but also harms people around them and future generations too.
