There are several ways to protect yourself from harmful electromagnetic fields, including limiting exposure to radiofrequency electromagnetic frequencies. EMF protection can take many forms, from pendants worn around the neck to objects used to create “safety bubbles” in your home. In addition, researchers use color-coding techniques to measure changes in a patient’s energy field before and after using EMF protection products. These color-coding techniques can reveal significant differences in energy patterns in different body parts. Read on to learn about the best EMF protection for you.
ICNIRP reviews the literature on radiofrequency EMFs
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has systematically reviewed the literature on radiofrequency electromagnetic fields (RF EMFs). These studies have sought to determine the potential health effects of these signals. The ICNIRP reviews of the literature on radiofrequency EMFs are intended to help guide public policy regarding exposure to non-ionizing radiation. The current guidelines for radiofrequency EMF exposure were published almost 20 years ago and are due to be revised shortly.
ICNIRP has critically evaluated two recent reports, the NTP (2018a) and Falcioni et al. (2018), to determine the validity of the results. The NTP report claims that RF-EMF exposures cause schwannomas in rats. However, schwannomas, in general, are rare in humans, and the ICNIRP has not found a study examining the risks of exposure to RF EMFs.
Despite the lack of a scientifically verified mechanism for RF EMFs, these findings have become a significant subject of study in the scientific literature. Researchers have employed empirical methods to assess the potential health effects of RF EMFs. For example, several studies have examined the effects of RF-EMF exposure on cancer rates and cellular processes. In contrast, epidemiological research has investigated the associations between reported RF-EMF usage and cancer outcomes.
Effects of localized exposure on nerves
Although the effects of EMFs are not yet fully understood, some studies have pointed to possible symptoms of EHS or electromagnetic hypersensitivity. The scientific community is still trying to establish a definitive relationship between EMFs and leukemia. However, current studies suggest that as many as 1.5 to five percent of childhood leukemia may be caused by exposure to ELF-EMFs. Therefore, European scientists are urging further research and better monitoring to determine whether exposure to EMFs is a cause for concern. Furthermore, a review of the current evidence for low-frequency EMFs indicates that these fields may cause neurological and psychiatric problems in humans.
Further studies are needed to determine whether EMFs cause cognitive impairment in humans. The study will examine the cognitive and behavioral effects of RF-EMFs at various levels of exposure. It will also investigate whether there is a dose-response relationship between RF-EMFs and mental performance. Currently, only animal studies have been conducted to determine whether or not EMFs cause cognitive impairment in humans.
In rats, studies have shown that exposure to 916 MHz, ten w/m2, and 10 watts/m2 may alter memory and learning. In addition, long-term exposures to RF-EMRs are also known to cause memory deficits. For example, Saikhedkar et al. (2014) exposed rats to 900 MHz for 15 days. In this timeframe, EMF exposure induced learning and spatial memory deficits. Furthermore, hippocampal neuronal degeneration was observed.
Effects of whole-body exposure on body temperature
The ACGIH 2017 guidelines for minimizing the adverse health effects of hyperthermia recommend limiting the rise in body temperature to +1degC above normothermia. But this goal requires substantial knowledge of each situation. Once the core body temperature increases above this value, EMF exposure causes harm. Therefore, ICNIRP uses a conservative temperature rise threshold of 4 W kg-1 averaged over 30 min.
There are some cellular and molecular mechanisms involved in whole-body EMF-induced temperature increases. For example, a recent study found that exposure to an EMF field with a SAR of 1 to 4 W/kg increased body temperature. In people with impaired thermoregulation abilities, the increases may be even higher. Similarly, higher temperatures are likely to occur in certain body parts, such as the hands, feet, and abdomen.
The rate of energy deposition is essential in understanding the health risks of radiofrequency (EMF) exposure. The energy deposition of EMFs depends on the frequency and type of RF fields, as well as the shape and size of the body. The effects of radiofrequency exposures are usually quantified in terms of the “specific absorption rate,” which describes how much power is absorbed per unit mass. Moreover, the amount of energy absorbed is nonuniform throughout the body.
