Temperature extremes can lead to the risk of premature death – The researchers

19 Sep

Extreme temperatures in summer and winter can increase the risk of premature death in people with cardiovascular disease, the researchers from Australia, whose work is published in the Journal of the American Heart Association’s Cardiovascular Quality and Outcomes.

Scientists from Brisbane for the first time investigated the relationship between the average daytime temperatures and years of life lost as a result of cardiovascular mortality. Years of life lost were measured on the facts of early death compared with life expectancy.

The researchers note that their findings are important for understanding how the human body reacts to changes in the environment and the general tendency to weight gain.
It was noted earlier that extreme temperatures can contribute to spikes in blood pressure, changes in blood viscosity, cholesterol.

“With the increasing incidence of obesity and similar conditions, including diabetes, more people will be particularly sensitive to high or low temperatures, which can lead to an increase in diseases provoked by extreme temperatures” – quoted in the message words of Dr. Kunrui Huang School of Public Health and Institute of Health and Biomedical Innovation at

The scientists collected data on daily temperatures in Brisbane from 1996 to 2004 and compared them with information on deaths due to cardiovascular diseases in the same period.

A typical summer in Brisbane is hot and humid, while winters are mild and dry. The average daily temperature was 20.5 degrees Celsius, the lowest figure since the winter – 11.7 degrees (1% of the days in a year) and a maximum in summer – 29.2 degrees (1% of the days in a year).

Scientists estimate that about a million people have lost the day with peak temperatures (estremalno low or extremely high) 72 years of life due to premature heart or vascular death. The risk of premature death was higher if the extreme heat lasted two or more days.
Scientists attribute this to the high load on the heart and high loading ambulance services in those days. In this extremely cold temperature cores or people with diabetes suffer a little easier, the authors note. To avoid tragedy in cold weather you just in time to get warm in the room.
