Wind turbines are terrible for the health of the millions of birds and bats they slice and dice every year – and they’re not much good for humans either: they can even stop your heart working properly.
This was the conclusion of an experiment conducted recently by a medical team in Mainz, Germany, led by Professor Christian-Friedrich Vahl.
Interviewed in Allgemeine-Zeitung, Vahl said that the Low Frequency Noise generated by wind turbines can weaken the heart muscle and change the blood flow.
Prof. Wahl became interested in infrasound and its impact on health after a friend who lived near a wind park had complained of feeling continuously sick. It is known that all around the world people living near wind parks often experience health issues – some being severe.
The group led by Prof. Vahl conducted an experiment to find out if infrasound has an effect on heart muscle strength. Under the measurement conditions, the force developed by isolated heart muscle was up to 20 percent less.
The strength of the heart muscle is important in the event the aortic valve becomes caked up and thus more narrow. According to Dr. Vahl: “This changes the blood flow and the flow noise.”
Now researchers are discussing whether these changes can pose an additional risk to the function of the heart, the Allgemeine Zeitung reported.
Citing the results, Prof. Vahl said: “The fundamental question of whether infrasound can affect the heart muscle has been answered.”
The researchers conclude: “We are at the very beginning, but we can imagine that long-term impact of infrasound causes health problems. The silent noise of infrasound acts like a…
