A person can typically survive without water for about 3 to 5 days. This duration varies depending on several factors such as environmental conditions, activity level, age, health status, and individual characteristics. While some rare cases report survival slightly longer, generally without water, organ failure and death occur within a few days. Conditions like hot weather, physical exertion, and illness can shorten this time significantly. The well- known "rule of threes" summarizes this as 3 minutes without air, 3 days without water, and 3 weeks without food.
