Appearance and Internal Aging

The 2016 document examines the link between physical appearance and internal aging, suggesting that dissatisfaction with one's appearance may be tied to age-related dissatisfaction and cognitive dissonance. It notes that skin condition can reflect the health of internal organs and the body's ability to synthesize vitamin D. Epidemiological studies, including one with twins, have found connections between appearance, longevity, telomere length, and disease risks. Lifestyle factors like UV exposure, obesity, smoking, and depression can impact both aging and appearance. The paper also points out that body shape, particularly waist circumference and waist-hip ratio, is associated with health risks such as cancer, cardiovascular disease, and metabolic syndrome. Facial features like sagging and wrinkles may indicate biological aging and are linked to cardiovascular risks. The document stresses the need for more research on the relationship between appearance and health, taking into account genetic, cultural, and dietary factors.
