Health is measured by a bar next to your energy bar in the bottom right corner of the user interface (UI). The health bar is only visible while inside of The Mines, the Secret Woods or when the meter is not full. Outside of the Mines, the most common ways to lose Health are by getting hit by the train on the Railroad, or by the Slimes in the Secret Woods or in the Slime Hutch.
You can replenish health either by consuming food, sleeping, using the Spa, or eating Stardrops. Maximum health capacity is increased by 5 for each level gained in the Combat skill, and can be increased further by taking the Fighter and Defender professions in the Combat skill tree.
You will pass out if your health reaches zero. Clint, Linus, Maru, Robin, or Harvey, whoever has the highest friendship, will awaken you. Depending on which one it is, you may wake up in the entry room of the mine, in your bedroom, or in Harvey's Clinic. If you pass out inside the Skull Cavern, you will be awakened inside the hospital.
While passed out, you will lose money, items, and current progress in The Mines or Skull Cavern. Items that have been lost are non-retrievable, so it is a good idea to keep your valuables in a chest when exploring. The amount of money lost is defined by your current money. Up to 5000g (as of version 1.06) can be lost during the unconsciousness.
- When eating healing items, you gain approximately 12.5% more health than what is displayed in the tooltip.
