A new report now wars that smoke from outdoor fir pts and BBQs can cause hear disease, lung disorders and even cancer.

According to lead author Professor John Wargo, from Yale University and a member of the Connecticut-based health body Environment and Human Health Inc (EHHI), “The particles contained in wood smoke can have a strongly negative effect on human health and can cause lung diseases, cardiovascular events and cancer.”

The International Agency for Research on Cancer says, wood smoke contains at least five cancer-causing chemicals.

The report warns summer wood burning has increased by 25 per cent in recent years, with outdoor fire pits and BBQs being advertised for use on decks and patios, which allows smoke to enter people's homes.

The scientists explain very fine particles and gases from wood smoke have been proven to enter buildings after outdoor burning.

Furthermore experts are of the opinion that air pollution can worsen symptoms for people living with a heart or circulatory disease.

They say that the best way for people with asthma to stay safe is to take their preventer inhaler as prescribed and carry their reliever inhaler with them at all times.

Asthma symptoms get worse around fire pits or barbecues, says a research from May last year that suggested scented candles could be clogging up the air in people's home, putting their families at risk of inhaling dust and fungal spores.

Researchers from San Diego State University investigated various factors that contribute to air pollution inside homes.

As expected, cigarette and marijuana smoke clog up indoor environments.
