In what way can the human body discharge?

Generally speaking, people only need to discharge when operating some precise instruments (electronic components, such as computers). Because people are likely to be charged by friction.

In winter, when people touch something, there will be a "beep" discharge sound, which is the reason.

The specific measure of discharge is grounding. If the requirements are not high, just touch the metal door handle, window frame and so on. If the requirements are very high, there are special grounding wires and gloves, which may be sold in the computer city.
