Hunger, Thirst, and Sleep Deprivation

After 24 hours, if you haven’t eaten, slept, or had a (nonalcoholic) drink, you risk fatigue damage. Like running, the damage starts at a mere 1S and increases over each interval it is taken. The interval for hunger is 6 days, for thirst is 2 days, and for sleep is 3 hours. This damage stops when you eat, drink, or sleep, respectively.
