About this Mod
Low Health Warning is a lightweight client-side Minecraft QoL mod designed to keep you aware of dangerous health levels without getting in the way of gameplay.
When your health drops below a safe point, the mod displays a clear “Low Health” message above your hotbar, giving you an instant visual warning when things start to get risky. Whether you are exploring caves, fighting mobs, playing survival, or dealing with intense PvP moments, this simple warning helps you react faster before it is too late.
The mod is built to be clean, fast, and non-intrusive. It does not add complicated menus, unnecessary effects, or heavy features. It simply does one useful job and does it well: warning you when your health is low.
Perfect for players who want a small quality-of-life improvement that feels natural in Minecraft while staying lightweight and easy to use.
