Hunger and Thirst by alayton at Dec 27, 2013 9:38pm
DayZ standalone introduces much more complicated hunger and thirst mechanics compared to the mod. Instead of your hunger and thirst being satisfied as soon as you eat or drink anything, each type of food and drink restores varying amounts of energy and can add or remove water. Additionally, your stomach can only hold a limited amount of food and water.
This guide was written very early on. Much more information about hunger and thirst is available in our Status Effects guide, as well as information about other effects in the game.
When you eat a box of cereal, it restores around 1000 energy, and drains 250 water. Eating sardines only restores 333 energy, but adds close to 100 water. Drinking a can of soda restores a bit less than 150 energy and adds over 300 water, while drinking from a canteen doesn't give any energy, but adds 1000 water.
When you have less than 100 energy, you start losing health and blood. However, when you have a ton of energy and plenty of water (3500 and 3000 respectively), you start regenerating blood. Once your blood is refilled, you regenerate health instead.
Dehydration is much more dangerous than starvation: you lose five times as much health and twice as much blood. Once you accumulate a water deficit, it can be difficult to recover from it if you wait too long.
While they don't tell you exactly what's going on with your character, the status messages that pop up can still help you figure out what you need to get yourself healthy again. Keep in mind that there are other effects that share some of the same messages, so this is by no means a conclusive way of diagnosing yourself.
When you're hungry, you see the following messages:
"My stomach grumbles" "I'm feeling hungry" "I want to eat something" "I feel hungry"
When you're very hungry, you see these messages:
"I'm extremely hungry" "My stomach grumbled violently" "I'm starving"
When you're starving, you see:
"I'm dying of starvation"
When you're thirsty, you see these messages:
"I feel thirsty" "I'm thirsty" "I need a drink" "I feel like having a drink" "I want to drink something"
When you're dehydrated, you see:
"I really need to drink"
When you're badly dehydrated, you see:
"I'm dying of dehydration"
You can also eat and drink too much and overfill your stomach. Once you see these messages, if you keep eating or drinking, you're probably going to end up vomiting:
"My stomach feels absolutely stuffed" "I feel over-fed" "My stomach feels much more full then it's normal"
If you get to the point that you see these messages, vomiting is almost guaranteed:
"I am close to vomiting" "I think I'm going to vomit..." "I'm going to vomit..."
