Health – Heart-circulatory system, heat regulation, blood
The heart-circulatory system is the human body’s transport system of the human body and responsible for the maintenance of blood circulation. Oxygen and nutrients are transported to every cell of the body and their metabolic products removed. In addition the heart-circulatory system also plays a central role in protecting against illnesses and in heat regulation. In industrialised counties illnesses of the heart-circulatory system are amongst the most frequent causes of disease and death. In particular stress, smoking, lack of exercise and an unhealthy diet are responsible for this.
The influence of EMFs
The effects of high and low frequency EMFs on the heart-circulatory system have been studied in many scientific papers. In so doing cardio vascular changes, such as changes in blood pressure, heart rate, electrocardiograms (ECG) and blood circulation were investigated in connection with mobile telephone use or occupational radiation exposure.
The majority of studies noted no change to the pulse, blood pressure and heart beat due to high frequency radiation. Several deviations in the results could be attributed to other influences. No clear indications of increased blood circulation due to mobile telephone use were determined. The feeling of warmth that has often been reported is primarily due to holding the telephone next to the ear (insulation effect) and the warmth of the battery, not due to additional radiation exposure.
The current studies provide no evidence for measurable effects on the heart-circulatory system in the range of low frequency radiation. Furthermore no connection with cardiovascular illnesses could be observed.
