Since it takes a bit of time for these things to kill you, it's possible to make it through a very quick stint in outer space. At most, an astronaut without a suit would last about 15 seconds before losing conciousness from lack of oxygen. (That's how long it would take the body to use up the oxygen left in the blood.)

Most healthy dogs can go up to five days without food, though that number is only true if your pet is still drinking plenty of water. Some can even go up to seven days without, though you should never let things get that far without taking your dog to the vet.

Water fast (24–72 hours) The water fast lasts for 24–72 hours. You should not water fast for longer than this without medical supervision because of health risks. Some people may feel weak or dizzy during a water fast and may want to avoid operating heavy machinery and driving to avoid causing an accident ( 7 ).

Very healthy people can live a day or so longer. Those who are less healthy or exposed to very hot or cold weather may not survive as long. To stay healthy, you should continuously replenish your fluid supply. Many experts recommend drinking two quarts (64 ounces or about eight glasses) of water each day.

There are no precise answers. In general terms, the human body can go two to three days without water and, it is often said in survival guides, 30 to 40 days without food of any kind. (Many of these guides also discourage people from scavenging for wild plants or shrubs because of the adverse effects these can have.)
