Health

----
Characters, like colonists, raiders, etc., can become injured (via the environment or fighting). 
Each injury affects a different part of the colonists' well being, and can be found under a character's Health tab.
Under the health tab there are two sub-tabs, one for a health "Overview" which includes medical treatment preference and food restriction (1.0 onwards), and a second tab for scheduling any "Operations" that a colonist requires.
==Health Systems==
Pawns have the following health systems.

==== Sight ====
Sight is a capacity that contributes to stats including shooting accuracy, melee hit chance, and for colonists, nearly every work stat. Humans and animals have eyes, while scythers and centipedes have functionally equivalent sight sensors. Losing an eye or sensor reduces sight by 50%. Humans aged 50 or older may develop cataracts which drastically reduces sight by 50%. An eye can be upgraded with a bionic eye.
==== Hearing ====
Hearing is a capacity that contributes to trade price improvement. Hearing is reduced by damaged, missing ears, or hearing loss. Hearing can be improved past 100% with a bionic ear, however no derived stat benefits from doing so.
==== Moving ====
Moving is a pawn's capacity to use their legs to move about. It's a major factor in a pawn's overall movement speed. Moving is reduced when a leg, femur, tibia, foot, toe or their spine is injured.
Consciousness applies a 1 for 1 multiplier on moving, while breathing and blood pumping does the same but only up to -10% moving, so anything that affects any of these stats will also increase or reduce moving by the same amount. Moving is also directly reduced by certain ailments including bad back and frailty. 
Any time a pawn's moving is reduced to below 15%, they become incapacitated and can no longer do anything. They can be rescued or captured at this point. An injured pawn may eventually recover on their own as the pain levels drop, although blood loss may prevent this or cause them to collapse again.
==== Manipulation ====
Manipulation is a pawn's capacity to perform any task with their hands. It is an important factor in almost every task a colonist can perform. 
Anatomically, bipeds use their left and right arms for manipulation, and each side contributes its efficiency level to 50% of the manipulation stat. Total loss of a shoulder, arm, radius, humerus or hand will render that side totally useless and reduce the pawn's manipulation by 50%. Loss of a finger will result in about an 8% manipulation penalty per finger. For quadrupeds, manipulation is reduced by injury to their jaw instead. For both, injury to the spine will also reduce manipulation.
Consciousness applies a 1 for 1 multiplier on manipulation, so anything that affects consciousness (pain, brain damage, diseases, drugs, joywires, etc.) will also increase or reduce manipulation by the same amount. Manipulation is also reduced by ailments including bad back and frailty. Manipulation is modified by prosthetics including power claws, prosthetic arms, and bionic arms.
==== Talking ====
A character's capacity of speech. Directly affected by consciousness.
==== Eating ====
Eating is the capacity of biological pawns to consume food and is a major factor of Eating Speed. It is reduced by a damaged jaw. Even when missing a jaw a pawn can still eat, though at a reduced rate. A damaged or missing jaw can be replaced with a denture or bionic jaw
==== Breathing ====
The ability of a character to breathe. Affects consciousness and movement.
==== Blood Filtration ====
A character's ability to fight off diseases. Affects consciousness and immunity gain speed.
==== Blood Pumping ====
Blood Pumping is an essential function provided by the heart. It directly influences the moving stat. A pawn whose blood pumping reaches 0% will die instantly.
==== Digestion ====
Digestion is a pawn's ability to digest food and convert it to energy efficiently. The better a pawn's Digestion value, the less rest they will need. A pawn whose Digestion reaches 0% will die instantly.
==== Consciousness ====
Consciousness is a creature's ability to remain active, and in the case of your colonists, controllable. Blood loss, starvation and pain can have a serious effect on a creature's consciousness if they reach higher levels. Pawns below 30% consciousness will not wake up.
When a medical operation is performed, anesthesia is induced, which renders the person unconscious until the effect of the anesthetic medication has worn off. This makes them incapable of moving, along with being incapable of leaving the bed.
Consciousness is directly influenced by Efficiency of consciousness source, Pain, Blood pumping, Breathing and Blood filtration. The formula is:
 E(C) = E(CS) * (1 - Clamp((Pain - 0.1) * 4 / 9, 0, 0.4)) * (1 - 0.2 * △E(BP)) * (1 - 0.2 * △E(Br)) * (1 - 0.1 * △E(BF))
where
 E(C) is the Efficiency of Consciousness
 E(CS) is the Efficiency of Consciousness source (e.g., the brain)
 Pain is the total pain
 △E(BP) = 1 - E(BP), E(BP) is the Efficiency of Blood pumping
 △E(Br) = 1 - E(Br), E(Br) is the Efficiency of Breathing
 △E(BF) = 1 - E(BF), E(BF) is the Efficiency of Blood filtration
From the fomula, we know that when total pain is below 10%, it makes no influence on consciousness. And when 10% <= pain <= 100%, the fomula can be simplified as: 
 E(C) = E(CS) * [(Pain - 0.1) * 4 / 9] * (1 - 0.2 * △E(BP)) * (1 - 0.2 * △E(Br)) * (1 - 0.1 * △E(BF))

== Health tab ==
All creatures have a health tab, located above the pawn's inspect pane.
:Overview tab
::The first section lists the creature's type, gender and age. Hovering over this section will display the creature's exact age and date born.
::Self-tend (turned off by default) allows a doctor to tend their own wounds, although with reduced efficiency.
::The creature's bodily systems are listed here with their current effectiveness. Not all systems are found among all types of creatures (i.e. animals don't have Talking).
:Operations tab
::The Operations tab is only available for colonists, colony animals, and prisoners. Bills can be added here to request surgical operations.
:Injuries
::Listed here are the creature's health conditions and injuries. Implants, bionic parts, and prosthetics are also listed here. Hovering over an entry provides detailed information.
::A red blood droplet indicates a bleeding injury. The size of the droplet indicates severity of the bleeding. Overall bleeding rate is listed at the bottom.
::An open circle indicates a condition that needs tending, usually requiring periodic treatments before fully cured. A solid circle indicates the condition has been tended to.
::A bandage icon indicates a treated injury. A white bandage indicates high quality treatment. Darker shades indicate lower quality treatment, more likely to result in scarring or infection. See Doctoring
==Cold and Heat Injuries==
Hypothermia: Causes a negative thought, and pawns will eventually lose consciousness.
Frostbite: Can cause limbs and fingers/toes to fall off. 
Heatstroke: Causes a negative thought, and can affect consciousness and even set a pawn on fire.
Burns: Causes low-medium pain and creates a risk of infection.
==Treatment==
For most injuries, you can treat colonists with or without medicine (with typically better results if a medicinal substance is provided), and also have them lay in hospital beds or any other bed or sleeping spot assigned as a medical spot, though Hospital Beds further improve the chance of them being treated properly. Humans heal wounds at a base rate of 8 damage per day before bonuses.
===Improper Treatment===
Treating an injury poorly may result in scarring, reduced healing rate or infections.
===Operations===
Under the Health tab, you can assign an operation to a colonist by clicking on the bill sub-tab. Operations cannot be performed without a proper Medkit to apply an anesthetic. Operation success chance depends highly on the doctor's skill level. Keep in mind that keeping the room as clean as possible (also optionally with the use of sterile tiles) will help preventing possible infection. As of Alpha 16, there are three categories of surgery failure – minor, catastrophic, and ridiculous. Ridiculous hits all body parts, minor and catastrophic hit parts near the surgery site.
=====Transplants=====
For missing internal organs, either a donor organ or an artificial equivalent can be used. Some diseases can be cured through a transplant. Artery blockages can be cured with a heart transplant and asthma can be cured with lung transplants. Be wary that your colonists may suffer mood penalties when you harvest an organ, with the "donor" will suffer a -30 mood penalty for over a week. See Human Resources for details and mitigation strategies.
=====Limb Replacement=====
From peg legs to bionic arms, you could either replace a colonists' missing limbs, augment them, or cruelly punish your enemies with peg legs out of spite. 
Bionic parts have a bonus to specific actions or movement. For example, a bionic leg will increase your colonist's moving speed by 12.5%. Having a second bionic leg will increase the speed further by 12.5%, so having both right and left bionic legs will increase the speed by 25%.
=====Implants=====
You can install implants onto a natural part to improve its functions. 
Implants are not mutually exclusive so you can have more than 1 per part.
=====Amputations=====
Limbs can also be removed due to health reasons. If an arm/leg becomes infected it can be amputated to save the person.
