Increasingly frequent and intense droughts and heatwaves encourage the outbreak of forest fires, which can then spread rapidly thanks to the wind or the nature of the vegetation and soil. In recent times, such instances have been observed in parts of Europe, North America, the Pacific, and North Africa.
It explains that inhalation of these fumes – which can generate suspended particles, carbon monoxide and other chemical substances – can lead to respiratory and cardiovascular issues, and is particularly damaging to firefighters and people with chronic respiratory conditions and cardiovascular disease.But there could be an even greater impact on health, according to a new study by researchers at the University of New Mexico’s Health Sciences.
For their research, the scientists exposed rodents to smoke from a wood fire every other day for two weeks. This observation is all the more alarming as forest fires are multiplying at speed around the world, exposing a growing number of people to these unhealthy fumes.According to Campen, “neuroinflammation is the seed for all kinds of bad things in the brain, including dementia, Alzheimer’s disease – the buildup of plaques – plus alterations in neurodevelopment in early life, and mood disorders throughout life”.
