Waterboarding

Waterboarding is a form of water torture in which water is poured over a cloth covering the face and breathing passages of an immobilized captive, causing the individual to experience the sensation of drowning. Waterboarding can cause extreme pain, dry drowning, damage to lungs, brain damage from oxygen deprivation, other physical injuries including broken bones due to struggling against restraints, lasting psychological damage, and death. Adverse physical consequences can manifest themselves months after the event, while psychological effects can last for years.
