How hunger and thirst drain
Hunger and thirst run from 100 to 0, and both are full when you start. Each drops by 1.5 per minute, but the speed depends on what you're doing:
| What you're doing | Speed | A full bar lasts |
|---|---|---|
| Standing still | ×0.5 | 2 h 13 min |
| In a vehicle | ×0.7 | 1 h 35 min |
| Walking | ×1 | 67 min |
| Running | ×1.5 | 44 min |
| Sprinting | ×2 | 33 min |
You can run without ever getting tired, but you pay for it in food and water. Also:
- once you start shivering from the cold (34.5° and below), hunger drains 1.5 times faster (cold);
- overheating by a fire makes thirst drain 1.5–2 times faster.
The food and water icons are on the right, with a percentage under each. Below 15% the icon blinks and you see "Hungry · eat something" or "Thirsty · drink something".
What happens at zero
Empty hunger takes 500 blood per minute, empty thirst another 500. With both at zero you lose 1,000 per minute, so full blood lasts 12 minutes (blood).

Eating or drinking takes 1.5–2 seconds, and you can do it with a weapon in your hands. Every item weighs 0.5 kg. Hot food and drinks only warm you up to 37°, but they keep the chill away for a while (cold).
Bottle and flask
When you finish a bottle of water or a flask, the empty container stays with you. To refill it, stand in water or get within 2 m of a fountain, fire hydrant or sink, and Use the empty bottle or flask: it takes 2 seconds. The flask is the better one: +150 blood instead of +100.

Raw meat turns up in loot and on zombie bodies. You can eat it raw, but that's −500 blood and a 50% chance of infection (blood). Better cook it on a campfire: stand by the fire with meat in your inventory and press your inventory key when "Cook meat" appears. All your raw meat cooks at once in 5 seconds. Cooked meat fills your hunger, gives +300 blood and a little warmth.
