Air fresheners and aerosols can make babies and their mothers ill, research from the University of Bristol’s Children of the 90s study has revealed.
A number of previous studies have shown that air fresheners and aerosols are responsible for high levels of volatile organic compounds (VOCs) in the home.
Children of the 90s (ALSPAC), which has followed the health and development of 14,000 children since before birth, is the first study to investigate the effects of VOCs on infants.
The researchers found that frequent use of air fresheners and aerosols during pregnancy and early childhood was associated with higher levels of diarrhoea, earache and other symptoms in infants, as well as headaches and depression in mothers.
32 per cent more babies suffered diarrhoea in homes where air fresheners (including sticks, sprays and aerosols) were used every day, compared with homes where they were used once a week or less.
They also suffered more from earache. Daily use of aerosols such as polish, deodorant and hairspray was associated with a 30 per cent increase in cases of diarrhoea and, to a lesser extent, an increase in vomiting.
Air fresheners and aerosols also affected mothers, with those who used them daily suffering nearly 10 per cent more headaches.
The most surprising result is the link between maternal depression and air fresheners. 16 per cent of mothers who used fresheners reported depression, compared with 12.7 per cent of those who seldom used them. This represents an increased risk of over 26 per cent.
The ALSPAC study monitored levels of VOCs in 170 randomly selected homes for a year to establish the household products most likely to raise levels of VOCs. In addition, over 10,000 mothers completed questionnaires about their use of these products. They also reported at various points during pregnancy and childhood on symptoms suffered by themselves and their children.
The paper’s lead author, Dr Alexanda Farrow of the School of Health Sciences and Social Care.at Brunel University, says: “Over 40 per cent of families in the ALSPAC study reported using air fresheners regularly. People may think that using these products makes their homes cleaner and healthier, but being cleaner may not necessarily mean being healthier.
“Air fresheners combined with other aerosol and household products contribute to a complex mixture of chemicals and a build-up of VOCs in the home environment. Pregnant women and babies up to six months may be particularly susceptible to the effects of this, because they spend around 80 per cent of their time at home. There may also be implications for other groups who are at home a good deal, such as old people.
“More research is needed, but in the meantime, it might be safer to limit use of air fresheners and aerosols in the home. Squeezing a lemon is just as effective at freshening the air.”
