A person crossing the desert typically needs about 3 to 4 liters (or about 0.8 to 1 gallon) of water per day to stay hydrated, depending on factors like temperature, humidity, and individual exertion levels. In extreme heat, this requirement can increase significantly, sometimes exceeding 6 liters. It's crucial to drink regularly to avoid dehydration, as symptoms can arise quickly in harsh desert conditions. Additionally, carrying extra water is advisable due to the unpredictable nature of desert environments.
Peeing in the desert will not do anything to conserve water. Not peeing will only make the person very uncomfortable.
