Radiowaves do hardly anything. No harm\nMicrowaves and infrared heat your body\nVisible light makes you visible and psychological healthy.\nUltraviolet can make you blind.\nX- and gamma rays go throught your body and make damage.\nFrom up to down, the more dangerous.\n\nFor all EMW: the more intensity, the more dangerous.\nthe more time of radiation, the more dangerous.\nThe closer to the source of the radiation, the more dangerous.

In a word, NO.  Now, in a much longer paragraph... :-)  After many years of study, there's not any conclusive evidence that exposure to WiFi (RF frequencies) has any effect whatsoever on living things and there are generally no health concerns, even if you placed your access point under your pillow.  RF exposure involves frequency, power and the duration of the exposure.  The human body most efficiently absorbs radio frequencies in the 30 to 300MHz range, and WiFi is at 2.4GHz.  So not only is the frequency much different, but WiFi products have strict power and RF emmissions requirements, such as 100 milliwatts maximum output power.  Plus, the WiFi RF energy is not "ionizing radiation" like it is UV light and Xrays, so WiFi frequencies pose no danger to human DNA the way prolonged sunlight UV rays cause skin cancers... What is actually of more concern is the RF energy from nearby FM radio stations!  (But they've been around much longer than WiFi, studied extensively, and again, nothing conclusive about any health concerns.)

I can answer that.\nHis body is running at a high frequency (9.3-10.5 Hertz)\nIts called electro magnetic pollution.\nDoes he use computers without radiation protection or a cell phone?\nI can help. That's what I do.\nAlain-Toronto

For some really interesting answers to this question I really reccomend a book called 'The Field' by Lynne Mctaggart. It looks into a lot of things that are really now coming to be understood on a new level by modern science. It is a fascinating book and although I didn't agree with everything it said it really opened my mind to some new ideas. It covers a wide range of subjects, many relating to traditional healing. The section on homeopathy is very interesting.

Faraday's Law: Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil. No matter how the change is produced, the voltage will be generated. The change could be produced by changing the magnetic field strength, moving a magnet toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil relative to the magnet, etc.

Current burns, voltage jerks the muscles.  Too much current, you're toast.  Too much voltage, your heart stops.\n\nStatic built up from rubbing your socks on the carpet probably won't kill you.\n\nSeveral years back, in the wintertime, there were some news reports of people whose car blew up at the gas pumps.  Supposedly it was due to static electricity.\n\nIt's rare to get "shocked" outside when getting in or out of one's car or touching it or whatever but it does happen.  I remember a couple times in the past 5 years when it happened to me. A tiny percentage of times I have done that but way more than zero.\n\nSo, I guess the combination of a spark and being by your open gas tank could kills you, indirectly.\n\nTaking an extreme counter-example, there was a girl struck by lightening at the WHFS alternative rock festival in DC a few years ago. Apparently it knocked her a few feet from where she was standing.  But, it didn't kill her.  She was lucky.\n\nStatic charges build up more easily in wintertime. The air is dryer.  Something about the air molecules is different when there is less moisture.  I forget what, but you have probably noticed more "static" shocks in winter than any other time of year, unless you live in a really cold, dry place.\n\nA three inch spark seems pretty far.\n\nIn high school physics class, they said that each inch that a spark travelled off a sphere through the air indicated 10,000 volts.  I think it was 10,000.  Well, you're not a sphere and you are probably not touching one but that still seems like a lot.\n\nI used to get shocks of half or three quarters of an inch  when touching the corners of walls at the house I grew up in all the time.  That was really nothing.  I barely felt it.  It was just a surprise to feel it, and also to see the spark leap between the wall and your finger.\n\nModern buildings have grounding wires on all the outlets and stuff like that, to prevent electrical problems.  Not sure what really old buildings are like.\n\nIf you are wearing a sweater or wool clothing, that could increase the amount of static charge you build up.  There are all kinds of things that could do it.\n\nIf it happens on warm, humid days when you are not wearing any wool or sweaters, that would really be strange.  If not, maybe it is what you are wearing or the atmosphere that is mostly responsible.\n\nAlso, carpet is a big factor.\n\nFeeling it hours later, that's freaky. That never happened to me.

Ok... I read the answers previously posted and they all sound reasonable close to the truth, so I'll leave them be.. they did fail to mention how a person is actually killed by a lightning strike... So I'll answer this for you...\nYour body uses the flow of charged ions to control many processes (i.e. Muscle movement, nerve signalling).  The flow of charge is more commonly known as electricity.  The average membrane potential in a human is -70 kilojoules(kJ), and the channels in your cells membrane can be triggered by an impulse of only about 20 kJ.  So when you get a current through your body with a potenial of thousands of volts... obviously there is going to be a disruption of the charge gradient.  Depending on the path of the current through the body, the effects will vary... the most dangerous path is for the current to travel through your heart.  Since your Heart is a muscle and is is controlled by an "electrical" signal, this extreme voltage can cause an over fibrulation of the cardiac muscles and essentially render then useless... kind of like if you were to take a slinky and stretch it out as fa as you can... its not goign to contract again, and is not something that can be easily fixed.  Hope this helps!

Electromagnetic waves??? thats something ive never heard of before. how about posting the article or the website online? \n\ni do know that electricity can be "transmitted" by magnetism, via electromagnetic induction. according to faraday's law, a changing rate of magnetic flux linkage induces an electromotive force, and thus induces current on a conductor. check out faraday's law at wikipedia for more info dude...

Various things you do cause a build up of static potential about your body.  How effectively you can release this potential affects how much you zap things/people around you.  Every person's individual resistance to electric current is different.  This along with things like whether or not you are constantly grounded, thus discharging any built up static potential on your body, affect your "electrifying" personality. :P  This is why people employed in working with sensitive electronics use things like grounding wrist straps or ground mats, etc before and while working with the electronic components. The mats and straps help get rid of any static potential build up.\n\nYou're just lucky enough, like my oldest sister, to be able to pop someone else at will.  I always stay out of arm's reach of her in the static filled winter time.

no....human bodies carry electric current very well and when you touch something with too much static, it goes thru that point in your body, and out another (into the earth). You're basically the earthing-wire.

From the point of view of Physics, an electromagnetic (EM) wave is a self propagating wave in space with electric and magnetic components. It carries energy and momentum which may be imparted when it interacts with matter. EM wave can be predicted by Maxwell's equations. \n\nFurther informations: http://en.wikipedia.org/wiki/Electromagnetic_wave

The earths magnetic field is static, but an Alternating Current source will fluctuate, reversing its  North-south polarity 60 times a second.\n\nThe affects of fluctuating magnetic fields are very different from the effects of a fixed field.\n\n"A strong changing magnetic field can induce electrical currents in conductive tissue, such as the brain. Since the magnetic field will penetrate tissue, it can be generated outside of the head to induce currents within, hence Transcranial magnetic stimulation. These currents will depolarize neurons in a selected part of the brain, leading to changes in the patterns of neural activation."\n\nSee the link below for more details:

Proper Voltage of Tolerance that a body can take is not harmful, but more than the tolerable can get body organs cooked.  \nElectricity never reamsin in the human body it just pass through.. for a brief millisecond...\n\n-- Hope this helps.. Goodluck =)
