Scientists have recently completed an incredibly long study into whether a chosen profession can lead an adult into contracting asthma. Their results were interesting. It turns out, in a study which took around two decades to completes, that those who work with cleaning fluids and similar chemicals, run a significantly higher risk of contracting asthma later in life than others do. The belief is that, over a long period of time people inhale small quantities of these chemicals which slowly damage the inside of the lungs. Eventually it’s thought that this damage must lead to asthma though researchers are unsure as to the specific details at this time.
There’s little that can be done at this point beyond recommend the use of less potent cleaning fluids and remembering to ventilate areas before you use such products. A lot of the worse exacerbation of asthma can be nullified or at least lessened if you always ventilate enclosed areas properly!
