University of Toronto finds link between heat and visual impairment in older people
Scientists at the University of Toronto have found that the heat has a negative effect on the vision of older people. This was reported on the website of the university.
Esme Fuller-Thomson and colleagues conducted a study in the United States, during which they found that those who lived in counties with an average temperature below 10 degrees were the least likely to age-related visual impairment.
For those pensioners who lived in regions with temperatures from 10 to 12 degrees, the chances of developing vision problems increased by 14%, for their peers living at a temperature of 12-15 degrees – by 24%, for residents of regions with temperatures above 15 degrees – by 44%.
At the same time, the relationship between average temperature and visual impairment, as the researchers emphasized, was practically not related to the gender, income and education of the participants. It was more active between the ages of 65 and 79, compared with people over 80.
According to scientists, the negative impact of heat on vision may be due to exposure to ultraviolet radiation, air pollution or infection and the breakdown of folic acid when the temperature rises. However, none of the hypotheses has yet been proven.
