Asthma Risk Is Increased By Second-Hand Smoke

We are all aware of the dangers of smoking to our health – the many toxins in cigarettes can cause numerous health problems, from an increased risk of certain cancers, lung disease and respiratory problems, to damaging the skin and increasing the risk of wrinkles, fine lines and thin skin. But what many people don’t realise is that second-hand smoke is equally dangerous. New studies have discovered that babies exposed to cigarette smoke have an increased risk of developing respiratory problems such as asthma in childhood.

In a recent study, scientists exposed smooth muscle cells from the airways of deceased 18 to 20 week human foetuses to varying levels of cigarette smoke. The results were interesting – those exposed to the smoke showed changes which were akin to the effects of inflammation in asthma. The results of the higher levels of smoke were alarming – while low levels of cigarette smoke showed changes similar to asthma, those exposed to high levels of smoke caused the death of the cell.

In children, these effects cause the airways to narrow which can make it difficult for babies to breathe. These effects would be particularly damaging to premature babies, according to researchers, as the airways are already far smaller than in full-term infants. Smoking is a harmful habit to anyone, but particularly to young children as their lungs cannot handle the effects of smoke, even if it is second-hand. You should avoid smoking around children wherever possible so as to limit the damage caused to their respiratory systems, but it is advised that you give up entirely in order to reduce the risk of health problems to yourself as well. If you’re unsure how to go about it, book an appointment to speak to your GP about the various ways you can give up smoking.
