The largest organ of the human body is the skin, which all too commonly tends to be neglected and unintentionally abused. Just a few millimeters thick, skin provides protection for everything inside it from everything outside, from weather to harmful substances.
Although you can’t tell by looking, the skin is a very active organ, reacting to external stimuli such as touch, cold, or heat, automatically rushing more blood to an injured section to expedite healing. It also provides input to protect the body, alerting you to injuries by means of pain, irritation, or changes in color or texture. It’s also a repository of the water and fats required by the body for wellness.
