The average weight of an adult human head is between 4.5 and 5.5 kilograms (10-12 pounds). This includes the skull, brain, facial muscles, skin, and other tissues. Variations can occur based on factors such as age, sex, and overall body size.
Understanding typical head weight is crucial in various fields. In medicine, it’s a factor in diagnosing and treating conditions affecting the head and neck. Ergonomics utilizes this information to design safer and more comfortable helmets and headrests, reducing strain and potential injury. Automotive safety research relies on head weight data to develop effective restraint systems and understand the biomechanics of head injuries in crashes. Historically, anthropological studies have examined skull size and weight to understand human evolution and variations across populations.
