The answer to this month's question, "Can electromagnetic waves affect emotions," is yes. Wherever there are electromagnetic (EM) waves (basically everywhere!), there is the potential for them directly or indirectly to affect the emotions. But what about the likely motivation behind the originally-posed question? Can EM waves affect your body directly by altering brain function and nerve impulses? Again, the answer is yes. There have been studies that indicate that EM waves applied to the brain can relieve depression, but not all of the effects of EM waves on the nervous system can be positive. Extremely intense EM waves can potentially kill someone--definitely an effect on emotions. There's a reason the microwave oven has a protective grid. Those microwaves, unchecked, can cause physical damage. What still isn't clear is how much everyday, low level EM waves can affect humans. There are EM waves associated with cell phones and with power lines, and while there are certainly wacko conspiracy theories about low-level EM waves being used for mind control, the long-term effect of such waves is still unknown.
