Global warming is likely to increase illnesses caused by under nutrition, due to the effects of heat exposure, researchers have warned. For the study published in the journal PLOS Medicine, the researchers analyzed daily hospitalization data covering almost 80 per cent of brazil between 2000 and 2015. They studied the link between daily mean temperatures and hospitalization for undernourishment according to the international Classification of Diseases.
"The association between increased heat and hospitalization for under nutrition was greatest for individuals aged over 80, and those 5 to 19 years," said the researchers from Monash university, Australia.
The study said that increased heat may cause illness through undernourishment in a number of ways: reducing appetites, provoking more alcohol consumption, reducing motivation or ability to shop and cook and exacerbate any under nutrition, resulting in hospitalization.
