This image is a humorous illustration depicting different types of headaches using simple cartoon-style drawings of human heads. It shows four side-view profiles of bald heads, with different shaded areas in red to represent the location and intensity of pain associated with migraines, hypertension headaches, and stress headaches. The first two heads illustrate migraines and hypertension headaches, where one side of the head is shaded in solid red. The third head has a red band across the forehead and temples to depict a stress headache. The fourth head is completely shaded in red, humorously suggesting an extreme or overwhelming level of stress or headache pain. This image aims to visually summarize and differentiate common types of headaches in a lighthearted, easy-to-understand manner through the use of simple graphics and labels.
