Increased risk of blindness when living in a hot area

Global warming is (too) bad for your health. Indeed: the global rise in temperature leads to the spread of some infectious diseases (such as Nile fever or malaria), increases the risk of hyperthermia and heatstroke (especially in summer) and increases the risk of cardiovascular (as well as respiratory) diseases from more vulnerable population groups.

But that’s not all: according to a new study by the University of Toronto (in Canada), living in a hot area will also increase the risk of visual impairment, especially among the elderly.

Link to air pollution?

To come to this conclusion, Canadian researchers studied the medical data of nearly 1.7 million Americans ages 65 and older. These numbers are associated with meteorological readings.

What did they discover? Compared to residents of cooler areas (where the temperature was on average less than 10°C for the year), residents of areas with an average annual temperature between 10°C and 12.7°C had a 14% increased risk of blindness. . This risk was increased by +24% (again compared to residents of ‘cold’ regions) for people living in areas where the average year-round temperature ranged between 12.7°C and 15.4°C.

According to scientists, high temperatures were particularly harmful (…]
