As I said, my home is far from perfect. I do know a few things, though. I know that many homes have hot spots of EMFs (electromagnetic fields) that should be avoided; especially while sleeping. Number one, the digital clock. Not your friend for many reasons, I agree. Your clock emits a very strong EMF field that drops off once you're about a foot away. You certainly want to make sure it's well away from your head while sleeping. Why? EMFs mess with our melatonin levels and we are most vulnerable while we sleep. Low melatonin can affect your sleep, mood and has even been linked to cancer (surprise, surprise). All electronic devices emit EMFs. The important factor, is that the EMF levels are low where you spend most of your time; sleeping, reading, watching TV, etc. One easy way to do this, is to make sure that these places are several feet from the closest electronic device. Keep in mind that walls don't protect you. If your refrigerator backs up to a wall and your favorite chair is on the other side, you could be sitting in a hot spot. For a little more reassurance, you could purchase a gaussmeter for $35 and test your house. Who knows, maybe you'll find some ghosts lurking around too.
If you want a more thorough exam, call your local electricity provider. They don't advertise this, but they will come to your house and give you a full inspection with their super duper gaussmeter. Just make sure you tell them that you're concerned about the EMF levels in your home when you call. You'll find that their "acceptable" levels are way higher than they should be, but just take note of the hot spots and move your furniture accordingly.
Making your home a clean, healthy environment is one small part you can do to protect your health and the health of your family. Certainly, more ramblings to follow...
