subject: Global Warming Could Save Lives [print this page] As the temperature rises, the planet's population is threatened by drought, floods and heat waves. WHO says more than 150,000 people already die every year as a consequence of climate change, and that many more will be affected in the coming years.
But it's dead, the other's bread: While the rest of the world hit hard by climate change, see the Danes seem to be exceptionally lucky. Not NOK that they avoid many of the climate change consequences - rising temperatures may actually help to save lives.
More heat, less death
In the study, the researchers mapped the relationship between temperature gradients in Copenhagen, on the one hand, and deaths and admissions to the other side. When Denmark is experiencing periods of warmer weather than normal, according to survey fewer patients with heart / vascular diseases are hospitalized or die - even in summer. They had expected that the heat could have a protective effect in the winter, but it was a surprise that the temperature gradients gave fewer deaths in the summer.
Luckier than others
In the study, researchers looked at how temperature gradients affect admissions and deaths in heart / vascular diseases, respiratory diseases and disorders of the brain's blood vessels. The statistical analysis showed that a temperature rise of 1 degree represented 1 percent fewer deaths and 1.1 percent fewer hospital admissions for people with heart / vascular diseases. Thus, they are lucky compared to other European countries. A large study from 2008 examined the corresponding relations in 15 European cities including Prague, Budapest, Zurich, Paris, Helsinki, London and Dublin. In almost all large cities increased mortality rates for heart / vascular patients in line with the temperature. Only in Dublin was also seen that the temperature elevations had a protective effect.
Unhealthy cold
Copenhagen and Dublin have similar climate in the warm period, and it is possible that the cold and rainy weather has a greater negative impact on mortality than a slightly higher temperature. The apparent success is explained partly because they are normally pretty unlucky when it comes to climate. It is not so much that the heat is healthy, but more that the cold can be dangerous. No one knows exactly why higher temperatures may be good for the heart / vascular patients. It is likely that the blood vessels constrict, the blood thickens and blood flow changes, depending on how much the body needs to warm up.
Temperature rise does not seem to be any difference in diseases of the brain's blood vessels. At least it seems that in our climate is cold weather is a major problem for the heart / vascular diseases than hot weather.
Lungs protection
Also when it comes to respiratory diseases will Denmark apparently be spared, even if temperatures were to rise? In the Danish study had temperature rises no significant impact on mortality, either summer or winter in fact, the researchers tend to the higher temperature in winter was good for lung patients.
And even if the temperature rises during the summer seems to provide more hospital admissions for respiratory diseases, we are probably not as hard hit as other places on the planet.
