At some point in your life, you have probably heard that cell phones and microwaves can cause all sorts of health problems, including cancer.
Some people claim that the electromagnetic fields, or EMFs, that are emitted by certain devices and household appliances give off radiation that has an ionizing effect on your body’s cells. But is there any truth to these claims? Keep reading to find out.
Understanding the Electromagnetic Spectrum
EMFs don’t come in just one form; they fall somewhere on the electromagnetic spectrum. The electromagnetic spectrum illustrates all of the different types of electromagnetic radiation and organizes them based on their wavelength and energy.
On one end of the spectrum are radio waves, which have the lowest energy and frequency and the longest wavelength. This makes them the least harmful type of electromagnetic radiation.
On the opposite end of radio waves are gamma rays, which are the most powerful form of electromagnetic radiation. As you go down the spectrum, the forms of radiation increase in energy and frequency while the wavelengths shrink.
When to Worry About EMF Exposure
Most of your household appliances and devices, including your cell phone, television, microwave, hair dryer, and computer, fall very low on the electromagnetic spectrum. Low-frequency EMFs give off an extremely mild form of radiation that is non-ionizing and generally considered to be safe for humans.
The only form of EMF exposure you should worry about is large doses of high-frequency EMFs, such as gamma rays, X-rays, and UV rays.
Thankfully, most people never come in contact with gamma rays, and in medical settings, X-ray exposure is always minimized. However, you can take steps to protect against UV radiation from the sun, such as limiting your direct sun exposure and always applying adequate sunscreen.
