Body image can be affected by outside influences. Media sources, such as television, the Internet, and magazines, often portray people closer to the commonly accepted ideal body type than the average body image in order to sell their products and services. Consequently, people, especially older children and young adults, are overly influenced by such depictions of body image. Family life can also affect children's perception of their body image. Parents who criticise how their children look, talk, or act, may often have a negative effect on the development of self-esteem in their children. Young people may also be affected by the comments of classmates and peers when it comes to their body image. Teasing is often a method used by young people to convey negative comments and hurtful words. Common characteristics for being teased include being too small or too large; too smart or too dumb; too popular or not very popular; and any of a number of other personal characterisations. Additionally, young people often try to pressure their peers to conform to what is currently popular in clothing styles, language, and other characteristics – all that can potentially hurt one's perception of their body image.
