Eczema and sunshine


I read an interesting bit of research recently, where the researchers claim children living in areas with more than average levels of sunshine, that is, higher UV light, end up with a reduced risk of developing eczema and food allergies.

With those living in areas with lower levels of sunlight, that is, lower levels of UV, end up with a higher risk of developing eczema and food allergies.

The researchers believe playing in the sunshine, exposes children to UV and this increases vitamin D production, which may affect the risk of eczema and food allergies.

Researchers assessed children across Australia and found on average those in the south of Australia had a higher incidence of food allergies, eczema and asthma. In fact research pointed to the risk being nearly twice as likely in the south as in the north. They also found more children allergic to peanuts and to eggs.

The research led by Dr Nick Osborne, from the European Centre for Environment and Human Health, a joint initiative between Plymouth and Exeter universities, commented,

"This investigation has further underlined the association between food allergies, eczema and where you live. We’re now hoping to study these effects at a much finer scale and examine which factors such as temperature, infectious disease or vitamin D are the main drivers of this relationship. As always, care has to be taken we are not exposed to too much sunlight, increasing the risk of skin cancer."
