Elderly residents of warmer regions of the United States are more likely to experience vision problems than their peers living in temperate climates. This was reported by the University of Toronto, where the study was conducted.
Esme Fuller-Thomson and colleagues to solveIt was seen in those living in areas with the lowest risk of age-related visual impairment (Alaska), where the average temperature was less than 10 degrees Celsius. The probability of a problem is 14% for those living in areas where the temperature is between 10 and 12 degrees Celsius, 24 percent higher for those living in the average temperature between 12-15 degrees Celsius, and 24 percent higher for those living in warm regions where the temperature is above 15 degrees Celsius. – 44% higher.
“The relationship between visual impairment and the average temperature in the county is of great concern if future research determines that the relationship is causal. We expect global temperatures to rise due to climate change. It will be important to monitor whether the prevalence of visual impairment among older people will increase in the future,” the scientists said.
The association between mean temperature and severe visual impairment was strong regardless of gender, income, and education of the participants. It was more pronounced in people aged 65 to 79 than in people over 80. Scientists have several hypotheses as to why heat damages vision: exposure to ultraviolet radiation from the sun, air pollution, infection, and the breakdown of folic acid with increasing temperature. However, none of these hypotheses can be considered proven.
