I constantly give off static electricity when Im touching other people in the office. It's not a big problem, but it's a nuisance. What's the reason for this and how can I prevent it?

Electro Static Discharge (ESD) is the sudden and momentary electric current that flows when an excess of electric charge, stored on an electrically insulated object, finds a path to an object at a different electrical potential (such as ground). The term is usually used in the electronics and other industries to describe momentary unwanted currents that cause damage to electronic equipment.

Causes of ESD

One of the causes of charge separation that creates an ESD event is the triboelectric effect, in which certain materials become electrically charged after coming into contact with another different material and then being separated. This is why people experience ESD events after walking on a rug, descending from a car, or removing some types of packaging. In all these cases, friction between different materials causes triboelectric charging that, when discharged, becomes ESD.

Prevention of ESD

ESD is a serious issue in electronics, because integrated circuits are made from semiconductor materials such as silicon and insulating materials such as silicon dioxide, which can break down if exposed to high voltages. Manufacturers and users of integrated circuits must take precautions to avoid this problem. Such measures include appropriate packing material, the use of conducting wrist straps and foot-straps to prevent high voltages from accumulating on workers' bodies, anti-static mats to conduct harmful electric charges away from the work area, and humidity control, because in humid conditions the surface layer of moisture on most objects conducts electric charges harmlessly to earth. Also, insulating materials prone to triboelectric charging should be kept away from sensitive devices as the charge accumulated on them can induce charge in the devices.

Is it true that when you ae working in the computer you absorb the static frequency or energy of the computer thats why when you touch a person it gives you a bit of a shock. How true is this?

Another thing i would like to know is that can be the shoes your wearing can be another factor? Sounds strange but i just observed that i can feel the static more when I'm wearing that particular shoes.

Many problems: destroying chips, inflaming cars, ...
You probably experience the first level: deterioration or destruction of electrical component, the second level can be seen on the net where several videos are illustration the case of a small spark in flammable environment

I can feel static whenever I'm touching a metal or a computer. Since humans have a positive or negative charge, when we touch electrical and electronic stuffs, it tends to shock us because of positive current coming out of them.

Can static energy cause any disease in our body?
