Let Go

SAM Can't Let Go Graphic Electricity flowing through our bodies affects our muscles and nervous system. The "Let Go" Threshold is the level at which we begin to lose control of our muscles. For most people this threshold is about 15 milliamps. At or above this level, the current flowing through our bodies interferes with our muscles' ability to function. You may have heard of people not being able to let go of an object while being shocked. This is because the electricity causes muscles to contract. Our muscles will remain contracted until the current is removed. Pain is generally felt at this level.
