The average adult human head weighs between 8 and 12 pounds. This figure includes the skull, brain, teeth, skin, muscles, and other tissues. Variations in weight can be attributed to factors such as age, gender, overall body size, and individual differences in skull and brain size.
Understanding head weight is valuable in diverse fields. In medicine, this knowledge is relevant to ergonomics, the design of protective headgear, and the study of head and neck injuries. In forensic science and anthropology, skull and head measurements contribute to identifying remains and understanding human evolution. Furthermore, this information plays a role in biomechanics research, particularly in areas focusing on posture, balance, and movement.
