Body image is a person's thoughts, feelings and perception of the aesthetics or sexual attractiveness of their own body. The concept of body image is used in several disciplines, including neuroscience, psychology, medicine, psychiatry, psychoanalysis, philosophy, cultural and feminist studies; the media also often uses the term. Across these disciplines, there is no single consensus definition, but broadly speaking, body image consists of the ways people view themselves; their memories, experiences, assumptions, and comparisons about their appearances; and their overall attitudes towards their respective appearances (including but not limited to their skin tone, height and weight) all of which are shaped by prevalent social and cultural ideals.
Body image can be negative and diminishing ("body negativity"), positive ("body positivity") or neutral in character. A person with a negative body image may feel self-conscious or ashamed and may feel that others are more attractive. In a time when social media use is pervasive, people of different ages are affected emotionally and mentally by the appearance ideals set by the society they live in. These standards can contribute in part to body shaming – the act of humiliating an individual by mocking or making critical comments about a person's physiological appearance.
