A stun gun is an electrical non-lethal self-defense device that uses high voltage to stop an attacker. Touching a person with the prongs of the device quickly immobilizes the attacker. However, because the amperage is very low, no serious or permanent injury is inflicted.
The stun gun is designed to key into the nervous system. It dumps its energy into the muscles at a high pulse frequency that makes the muscles work very rapidly, but not efficiently.
This rapid work cycle depletes blood sugar by converting it to lactic acid all in just seconds.
The resulting energy loss makes it difficult to move and function. At the same time, the tiny neurological impulses that travel throughout the body to direct muscle movement are interrupted.
This causes disorientation and loss of balance and leaves the attacker in a passive and confused condition for several minutes.
Although there is no significant effect on the perpetrator's heart and other organs, you have the time you need to get away and get help.c
