InOnce Human, Stardust has taken over the world and polluted nearly every corner of the planet. From water to soil, the world has become a hazardous wasteland, filled with toxic fumes and deadly radiation. Despitebeing a Meta-Human, you are not immune to the ravages of Stardust.
Exposure to pollution not only threatens your physical well-being but also takes a toll on your mental state. As such, pollution continues to be a constant threat, draining yourHealth and Sanity.While in polluted areas, you cannot even restore health using any means. Since you cannot always avoid these areas, it’s important tobuild up your pollution resistance.

How To Increase Pollution Resistance
Pollution resistance is an interesting mechanic inOnce Humanthat determines how well you can withstand the harmful effects of the polluted environment. It’s a measure of your character’s ability toresist the health draincaused by exposure to Stardust and its toxic byproducts.
Higher pollution resistance means you may venture into more polluted areas without your health depleting rapidly.You can increase your pollution resistanceby equipping gear(helmets, chest armor, and masks) that have the Pollution Resist buff.

Since gear items inOnce Humanare categorized into tiers,higher-tier items offer better protection.Early-game gear (Tier 1) provides a base pollution resistance of nine points, which can be increased to 12 by upgrading them to Tier 2. Chest armor and masks offer the most protection, with a base pollution resistance of 12 that can be upgraded to 16.
The best gear to boost Pollution Resistance in the early game is theTest Subject Outfit.It providesincreased pollution resistance per piece, making it highly effective in heavily polluted areas like Dayton Wetlands. you’re able to craft orupgrade this setanytime by using aGear Workbench.
Besides gear,certain foods and consumable itemscan temporarily boost your pollution resistance as well as help you recover your Health and Sanity. As such, you should always have consumables likeSanity Gummies,Ice Cubes, andFruit Teason hand to cure the pollution damage and reduce Sanity loss. Another great way you can heal any pollution damage is bysleeping in your bed.
While gear and consumables can significantly increase your resistance to pollution, it’s worth noting that there is no complete immunity. This means that you will still lose some Health and Sanity when in heavily polluted areas.
