Most humans cannot survive without food for 50 days. The longest hunger strike recorded is 74 days. According to Dr Sudhir Shah, who examined him in 2003, he went without food or water for ten days in which urine appeared to be reabsorbed by his body after forming in his bladder.

But one week is a generous estimate. Three to four days would be more typical, especially in difficult conditions like broiling heat. "You can go 100 hours without drinking at an average temperature outdoors," Claude Piantadosi of Duke University told Fox. "If it's cooler, you can go a little longer.

Severe dehydration can set in within a few hours depending on the activity level of your hamster, with death being possible if it goes without water for a day or two. If you suspect your hamster is dehydrated, you may have many questions.

Alcoholic beverages lead to dehydration. Try to avoid drinking alcohol 24 hours before giving blood. If you do drink alcohol, make sure to compensate by drinking extra water.

How long can you survive by drinking pee? An extra day or two, at best. A healthy person's urine is about 95 percent water and sterile, so in the short term it's safe to drink and does replenish lost water.

An article in Archiv Fur Kriminologie states the body can survive for 8 to 21 days without food and water and up to two months if there's access to an adequate water intake.

Generally, if the climate is just right and isn't too warm, healthy chickens are able to survive a full 48 hours without water. If you factor in heat or warm conditions, then that's going to be another story.

Death follows soon if rehydration is not started quickly. Dehydration is the loss of water and body salts through diarrhoea. The human body needs water to maintain enough blood and other fluids to function properly. If your body loses substantially more fluids than you are drinking, you become dehydrated.

The human body needs food and water to survive. A human can go for more than three weeks without food — Mahatma Gandhi survived 21 days of complete starvation — but water is a different story. At least 60% of the adult body is made of it and every living cell in the body needs it to keep functioning.

The time it takes to recover from dehydration depends on how dehydrated you are. If you are severely dehydrated, it's likely that you will be hospitalized and put on intravenous hydration for up to 24 hours to recover from dehydration, or until you're able to drink oral rehydration fluids yourself.

Dying from dehydration is generally not uncomfortable once the initial feelings of thirst subside. If you stop eating and drinking, death can occur as early as a few days, though for most people, approximately ten days is the norm. In rare instances, the process can take as long as several weeks.

Every person and situation is different, though the "rule of threes" gets at the desperate nature of what our bodies need: three minutes without oxygen, three days without water, three weeks without food.

When someone is no longer taking in any fluid, and if he or she is bedridden (and so needs little fluid) then this person may live as little as a few days or as long as a couple of weeks. In the normal dying process people lose their sense of hunger or thirst.

In general, turtles should be able to survive for about 12 hours without water. This depends on the temperatures of the environment and the type of turtle. When the environment is hot, he will dehydrate faster and die sooner. When it is cool, he might be able to make it throughout a whole day.
