Immune System Strength

Your Immune System determines how resistant your character is to diseases. It is not shown directly in the HUD, but it is calculated from your Energy and Water levels.

How It Works

• Based primarily on Energy & Water levels
• Higher nutrition = stronger immunity
• Low food or hydration weakens resistance
• Affects disease contraction & recovery speed

Important Thresholds

65%+ - Resists Common Cold & Influenza
95%+ - Resists Cholera
Below 50% - High infection risk

How To Boost It

• Keep Energy & Water in white
• Avoid starvation or dehydration
• Multivitamins temporarily boost immunity
• Stay warm and dry

Why This Matters

Many players believe disease contraction is random - it isn’t. A well-fed, hydrated Survivor with high immunity can drink from risky sources and resist infection far better than a starving one.

If you’re constantly getting sick, check your nutrition first. Fixing Energy and Water is often more important than immediately taking medication.

Environmental Conditions

Exposure to weather, temperature, and overeating can affect your character’s survival and increase disease risk.

Hypothermia

• Caused by prolonged cold exposure
• Wet clothing reduces insulation
• Causes rapid Energy loss
• Increases risk of Common Cold

Treatment: Get warm, dry clothes, use heatpacks, sit near fire.

Wetness

• Caused by rain or swimming
• Reduces clothing insulation
• Makes items heavier
• Lowers maximum stamina

Fix: Wring clothes, air dry, use fireplaces.

Stuffed Stomach

• Caused by overeating or drinking too fast
• 2L stomach capacity limit
• Leads to vomiting if exceeded

Prevention: Eat slowly, allow digestion between meals.

How Environment Affects Immunity

Cold and wet conditions indirectly weaken your immune system by draining Energy and Water faster. Survivors exposed to harsh weather without proper gear are significantly more likely to contract illness.

Staying warm, dry, well-fed and hydrated is one of the strongest preventative medical strategies in DayZ.
