Lesson Content/Board Summary

Body Image

Body image refers to how a person sees and feels about their body’s shape, size, and appearance. It includes personal thoughts, feelings, and attitudes towards one’s physical features.

Effect of Pubertal Changes on Body Image and Behaviour

Puberty brings physical and emotional changes that can influence how individuals perceive themselves. These changes affect confidence, behaviour, and social interactions.

The following are the effects of pubertal changes on body image and behaviour:

Development of self-consciousness about appearance.
Increased concern about body size, height, or weight.
Greater sensitivity to peer comments about looks.
Behavioural changes such as shyness, withdrawal, or trying to copy admired peers.
Positive effects such as improved strength, maturity, and sense of identity.

Misconception about Beauty as Presented in the Media

The media often presents beauty in unrealistic ways that can negatively affect young people’s self-image. Images of celebrities and models are sometimes altered to create false standards of beauty.

The following are misconceptions about beauty as presented in the media:

Beauty is defined by having slim bodies or muscular figures only.
Fair or light skin is considered more beautiful than dark skin.
Certain hairstyles or colours are superior to others.
Height determines attractiveness.
Perfect appearance is possible without flaws.

Individual Uniqueness

Every individual is unique in physical features, and no one body type or appearance is superior to another. Differences in size, shape, colour, and race are part of human diversity.

The following are aspects of individual uniqueness:

Physical features such as eye colour, hair type, and skin colour.
Height and body shape differences.
Racial and ethnic backgrounds.
Natural variations in growth and development.
Personality and talents that complement physical appearance.
