What Is the Healthcare Redux Sims 4 Mod?
The Healthcare Redux Sims 4 Mod is a modular, feature-rich overhaul that adds a full spectrum of health-related gameplay to The Sims 4. Instead of the base game’s simplistic “take medicine and get better” approach, this mod introduces realistic illnesses, chronic conditions, allergies, medical emergencies, and a detailed healthcare system. Each Sim is assigned a unique immune system level, affecting how often they get sick and how quickly they recover. The mod also brings in a variety of new diseases, from the common cold to deadly infections like tuberculosis, and chronic conditions such as asthma, migraines, and diabetes. It’s designed to make health management a meaningful and sometimes dramatic part of your Sims’ stories.
