New Delhi, A new research has claimed that the extreme hot or cold temperatures could increase risk of premature death due to cardiovascular disease. Researchers examined the association between daily averages temperature and years of life lost owing to cardiovascular disease. Years of life lost measured premature death by estimating years of life lost according to average life expectancy.
The outcomes of the study are important in a sense, how the body responds to temperate extremes, the growing obesity trend and earth's climate changes. With increasing rates of obesity and related conditions including diabetes, more people would be vulnerable to extreme temperatures, which could raise the future disease burden of extreme temperatures.
The research is based on the collected data on daily temperature in Brisbane between 1996 and 2004 that was compared to documented cardiovascular-related deaths during the same period. Brisbane has hot, humid summers and mild, dry winters.
The average daily mean temperature was 20.5 degrees Celsius, with the coldest 1 percent of days 11.7 C characterized as cold spells and the hottest 1 percent 29.2 C heat waves. Per 1 million people, 72 years of life were lost per day due to cardiovascular-related disease. The risk of premature Cardiovascular-related disease death raised more when extreme heat was sustained for two or more days.
