Make sure you get a machine with a full body mat. There are some cheaper devices that work on local areas only which will not give you nearly the same benefit. And the companies that sell the full body mats usually include a small local applicator anyway. The real benefit lies in the full body treatment. Also try to avoid the “new” wire mesh mats. While these mats claim to offer a more evenly distributed field, they lose the pure magnetic field that comes from a current loop. Make sure to ask.
It is critical to use only machines with low intensities between 0 and 70 uT (micro tesla). ALL the top companies (MRS 2000, QRS Quantron and Bemer 3000) found that the lower intensities work better than the stronger intensities. Here, MORE IS NOT BETTER. In Fact, it’s the opposite. The lesser field strengths actually worked better in clinical studies. If you are chemically sensitive, you will additionally want to have a machine that includes the picotesla range (MRS 2000 Only).
Make sure the machine uses frequencies that are closely aligned to nature. Ideally this would be around .5 to 25 Hz. Nature produces frequencies mainly in this range. Additionally Electroencephalogram EEG studies prove that the brain wave patterns are also roughly in this range from Delta to High Beta. Furthermore, there is a lot of good research that proves the biological window of frequencies the body best absorbs is roughly .5 -25 Hz.
It is critical that PEMF equipment switches polarity every few minutes. This is important because the human body will get used to a constant north pole or south pole polarity.
Make sure the unit has a good warranty. Because these devices are around $3000 to $4000 on average, it is very important to make sure you are under warranty for at least 2 years, 3 years is better.
Check to see if you will be supported AFTER you buy. Everybody is different and you may need a little help to insure you get the full benefit of the machine.
Look for a Device with a Biorhythm Clock or at least a machine that adjusts the frequencies to different times of the day. For example, you don’t want to be put to sleep in the morning or energized before bedtime. What you need is energizing frequencies early in the day and relaxing ones at night. Most machines DON’T offer this option, so ask.
