How many Coulombs of static charge can a human body hold without doing any harm?

A human body can typically hold around 10,000 to 20,000 Coulombs of static charge without experiencing harm, though this varies based on individual circumstances and environmental conditions. However, it's important to note that the charge that can accumulate is usually in the microcoulomb range (millions of a Coulomb), as a static discharge typically involves only a few microcoulombs. Charges above this level can lead to noticeable shocks, but they are generally not harmful unless in specific conditions (like in the presence of flammable materials).
