Body Temperature

Body Temperature is one of the core mechanics of Tough As Nails. Temperature works on a 5-tier scale, consisting of the following values:

• Icy
• Cold
• Neutral
• Warm
• Hot

Your body temperature will slowly change to match the environmental temperature, which can be affected by many different sources, including the following:

• Biome Temperature
• Time of Day
• Weather
• Altitude
• Immersion (Wet, On Fire, In Powder Snow, etc.)
• Blocks
• Thermoregulator
• Armor
• Held Items (Main or Off-Hand)
• Consumed Items (Internal Chill / Internal Warmth)
• Season (If Serene Seasons is installed)

Sources such as blocks, armor, held items, and consumed items will show a tooltip for whether they provide cooling or heating.

A Thermometer can be used to immediately check the current environmental temperature. When your body temperature is in the Icy/Hot range, you will be at risk of Hypo/Hyperthermia respectively, which will slowly damage you over time.
