Waterboarding is a controversial interrogation technique that simulates drowning. The person being subjected to it is strapped to a board, with their head inclined downward. Water is poured over a cloth covering their face, creating the sensation of suffocation and panic. This method has been widely criticized for being a form of torture. Many human rights organizations argue that waterboarding inflicts severe psychological and physical distress, violating ethical standards and international laws regarding treatment of detainees. Its use has sparked significant debate about the balance between national security and human rights.
