A recent study published in ‘Environment International’ has found that exposure to residential traffic noise can have an affect on the time it takes for women to fall pregnant.

Most healthy women of child bearing age take around six months to fall pregnant. However, this recent study found that exposure to just a 10 dB increase in road traffic noise around a woman’s home could be associated with a 8% increased risk of taking longer than six months to fall pregnant.

Noise delays pregnancy

The study was led by Jeppe Schultz Christensen of the Danish Cancer Society Research Center in Copenhagen, Denmark. It identified 65 000 mothers from the Danish National Birth Cohort who self-reported information on trying to fall pregnant. Road traffic noise was recorded at their addresses.

The World Health Organisation published a comprehensive report in 2011 on the health effects of exposure to noise. It found that heart disease was one of the most dramatic effects but cognitive impairment, sleep disturbance, tinnitus, high blood pressure and anti social behaviour were also identified. And, in Western Europe alone, almost one million lives are lost every year from traffic-related noise.

Previous research has also linked traffic noise with a lower quality of semen in men.
