After analyzing 56 studies conducted with more than 137,000 people, Australian researchers have shown that passive smoking was the main cause of triggering asthma attacks.
This chronic disease affects around 3.5 million French people, according to
The Conversation.
Published in the
Journal of Asthma
, the scientists' findings indicate that smoke inhalation disrupts the normal development of the lungs and immune system due to airway irritation.
The authors of the study point out, however, that passive smoking is very present in our society both at home and at work.
“Children were the main victims of passive smoking, exposed to the smoking of their parents, especially mothers, at home,” they write.
Beware of synthetic bedding and gas heating
According to Australian researchers, bedding is also a cause of the onset of asthma attacks.
According to them, nylon, microfibers and acrylic materials expose users to allergenic risks and an increased presence of dust mites, unlike feather bedding, for example.
“When bedding is made from non-natural fibres, it contains higher levels of allergens and dust mites.
The firmer weave of feather pillows makes them a more protective barrier against allergens,” they explain in
The Conversation
.
But that's not all.
After passive smoking and bedding, the study reveals that heating modes could also play a role in triggering asthma attacks.
Gas heating would generate higher carbon dioxide emissions than electric heating.
“Our research shows the importance of focusing on preventing some common family environmental factors in preventing asthma symptoms,” the scientists conclude.
