How Harmful Is Electromagnetic Radiation?

What is electromagnetic radiation? Since the dawn of the universe, electromagnetic waves have emanated to Earth as light from the sun. Thankfully, the ozone layer protects us from most of the UV rays and dangerous radiation. Nature's electromagnetic fields can direct migratory animals like birds or bats that hunt by sonar. They also reveal themselves as heat waves or lightning storms. Naturally occurring radioactive elements, like radium, uranium, plutonium and palladium, to name a few, all release radioactive particles, which are accompanied by a tiny electromagnetic pulse.

Some international studies suggest that animals are particularly sensitive to electromagnetic radiation. The Centre for Environment and Vocational Studies of Panjab University found that all bird embryos were damaged when exposed to 5-30 minute of EMF radiation (electro magnetic field). The Salim Ali Centre for Ornithology and Natural History found that the skulls and egg shells of baby birds were thinner when subjected to electromagnetic waves. They also speculated that 4 out of the 200 native bird species have gone extinct as a result. "Birds are known to be sensitive to magnetic radiation. Microwaves can interfere with their sensors and misguide them while navigating and preying," says lead researcher Ranjit Daniels.

Based on 25,000 articles published over a thirty-year time span, there is no conclusive evidence that long-term, low-level exposure to electromagnetic radiation raises a serious health concern. However, there are some gaps in the research that scientists are still working on. For instance, there have been some reports linking prematurity and low birth weight for children of electronics industry workers who come into regular contact with computer screens, electric blankets, radio-frequency welding machines, diathermy equipment and radar. Electronics workers exposed to high-level radiation also reported a higher incidence of cataracts. There have been further allegations that childhood Leukemia may be linked to electromagnetic waves and radiation as well. Some people report heightened sensitivity to electromagnetic fields, reporting headaches, depression, lethargy, aches, sleeping disorders and even epilepsy, although controlled studies have failed to suggest a definitive link. Current research is aimed at ensuring that cell phones, laptops and other common items employing electromagnetics do not cause cancer.

Even though there is no proof of harm, there are certain steps you can take to limit your exposure to electromagnetic radiation. When you are going outside, slather on UV ray protective sunblock and wear UV-deterrent sunglasses. Generally, mom's advice to "sit further back from the TV" or stand further back from the microwave is probably a good idea. Hands-free cell phones can keep the electromagnetic pulse away from your brain too. If you're particularly worried about your laptop or cell phone, then you can purchase electromagnetic absorbing products to protect yourself and your children.

There is no official statement on the dangers of electromagnetic fields, with regard to one's health. However, some people report experiencing crawling sensations, nausea, headaches, dizziness, anxiety and paranoia after 12 hours of exposure to areas that register as low as 50 milli-gauss of electromagnetic waves.
