how long can one survive in desert without water (Not a trick question..it means without juices etc also)

In extreme desert conditions, a human can typically survive about 72 hours (3 days) without water, though this varies based on temperature, activity level, and individual health. Survival for only 12-24 hours is too pessimistic for most people, while 48 hours is possible but 72 hours represents a more common upper limit before severe dehydration becomes fatal.
