Medical and illness
The cold-to-pneumonia chain, blood types, and the one Sakhal illness you cannot boil away.

Overview
Most DayZ illnesses are survivable if you name them correctly and treat the actual cause. The commonest mistake is treating symptoms while staying cold and wet.
The illness chain
Cold leads to flu leads to pneumonia. Each stage is harder to reverse than the one before, and all of them are accelerated by being wet. Getting dry and warm is the first treatment, not the last.
The medicine cabinet
Charcoal tablets for poisoning, tetracycline for bacterial infection, multivitamins for general resistance, saline and blood bags for blood volume. Blood type matters for transfusions — the wrong type will hurt you.
Heavy Metal Poisoning on Sakhal
This one catches everybody. It comes from eating snow or drinking contaminated water on Sakhal. Boiling does not help and chlorine does not help. A Filtering Bottle prevents it; Chelating Tablets treat it. Any guide that tells you to boil it away is wrong.
Blood recovery
Blood regenerates at roughly 0.3 per second only while both energy and water are healthy. If either drops below about 300, regeneration stops completely. Health then recovers slowly — around 0.03 per second — once blood is full.
