Urination, perspiration, defecation, lacrimal drainage(tears), lactation and vomitus.
When cells lose water and shrink, it is known as cellular dehydration. This can lead to impaired cellular function, as the lack of water affects important cellular processes such as nutrient transport, metabolism, and waste removal. In severe cases, cellular dehydration can lead to cell death.
Most living things lose water through evaporation from their body surfaces (such as through sweating or breathing) and through excretion (such as through urine or feces).
When you drink a regular glass of water, most of it is absorbed by osmosis through cells lining your small intestine. If you drink salt water then salt is added to the blood stream and your blood then becomes hypertonic to the entire solution (meaning is has more solute (salt) than normal), and your cells will lose water because your body is trying to dilute all that salt. So your cells will lose water and shrink.
Humans lose most of their water through urine excretion, sweating, breathing, and in feces. These processes help regulate body temperature, remove waste products, and maintain bodily functions. Drinking water helps replenish the lost fluids and prevent dehydration.
In the desert, the body can be exposed to extreme heat which can lead to dehydration, heat exhaustion, and heatstroke. The dry air can also result in rapid dehydration and sunburns. Additionally, sandstorms and lack of water and shelter can further contribute to physical stress on the body.
you get dehydrated (lose body water) by doing lots of exercise or doing a tiring activity
The body can lose about 10-15 of its water before death occurs.
The water loss is due to sweating to cool the body.
By sweating and peeing.

They might lose water via sweat. Also, a lot of water as water vapor is lost by breathing.

Water and Salt
Adults lose nearly two to three quarts (12 cups) of water every day.
Because your body is dehydrated from the alcohol and your body uses any water it can to clean the alcohol out of your system.
Water is hydrobolic
