Biological Effects or Health Effects? What is a Health Hazard?
When discussing electromagnetic fields (EMFs), it is important to distinguish between biological effects and health effects. Biological effects refer to measurable responses in the body due to exposure to a stimulus or change in the environment. These responses can include changes in bioelectrical activity, cellular function, or other physiological processes. Not all biological effects, however, lead to adverse health effects.
Exposure to high levels of electromagnetic fields can indeed trigger biological effects in the body. For example, strong EMFs can induce electric currents and heating effects in tissues. These effects are well understood and are taken into account when setting exposure guidelines to avoid potential health hazards. Current guidelines restrict exposure levels to EMFs that are not expected to cause detrimental health effects.
However, the debate arises when considering long-term exposure to low-level EMFs. Some individuals have reported a range of symptoms that they attribute to low levels of EMF exposure. These symptoms may include headaches, fatigue, sleep disturbances, or other non-specific complaints. Yet, scientific evidence does not support a direct link between these symptoms and EMF exposure.
Studies on Symptoms Related to EMF Exposure
Various studies have been conducted to investigate the potential health effects of long-term EMF exposure.
