Canadian scientists studied data on deaths from cardiovascular attacks among both sexes, aged 60-64 and 65-69 years, over a 15-year period (from 2001 to 2015), on hot summer nights.
The study, conducted by scientists at the University of Toronto in Canada, included people living in England and Wales. Moreover, the information relates exclusively to deaths in the summer months of June and July.
The researchers then compared the death rate with anomalous air temperature data recorded at night in June and July.
The results showed that a 1°C increase in night-time temperature was associated with a 3.1% increase in deaths from cardiovascular disease, but only among men aged 60-64.
The researchers note that they did not find any association between hot nights and the risk of heart attack or stroke for older men or women in either age group.
Researchers obtained similar results when they studied the effect of abnormally high temperatures in one area of Washington State in the United States, but there a one-degree Celsius increase in temperature at night was associated with a 4.8 percent increased risk of heart attack or stroke in men aged 60-64.
According to experts, global warming is increasing the abnormal temperatures in summer and summer nights, so men at risk should take preventive measures in advance.
Amazing study!
