Mummification occurs under which conditions?

• A. High humidity and low temperatures
• B. High environmental temperature, low humidity, and good ventilation
• C. Low temperature and high humidity
• D. Moderate temperature with moderate humidity

Answer: (B)

Mummification happens when soft tissues are dehydrated faster than they decay, so the environment must dry things out while keeping moisture and microbes from taking over. High heat speeds up the evaporation of water from the body, and very dry air (low humidity) makes that evaporation continue rather than stall. Good ventilation is key because it carries away the evaporated moisture, preventing local humidity from rising around the body and allowing the surface to stay dry. Together, these conditions remove water and inhibit microbial activity, leading to preserved, desiccated tissues rather than wet decay. When humidity is high, temperatures are cooler, or airflow is poor, drying doesn’t occur as efficiently, and decomposition is more likely.
