In modern society, the demands on individuals are far higher than those in the past few decades. Faced with high-pressure, high-intensity, and highly competitive learning and working environments, as well as complex and ever-changing family and interpersonal relationships, physical and mental exhaustion has become the norm for most people. Moreover, with the development and rise of social networks, ordinary people rely excessively on electronic devices, indulging in the virtual world, short videos, and games—resulting in a severe lack of effective social interaction in real life. Coupled with the pursuit of material possessions in real life, this leads to an imbalance in physical and mental states. Long-term exposure to such an environment has made the incidence of anxiety disorders and depression much higher than in the past.

Eczema is a localized inflammatory skin disease, which can be classified into acute eczema, subacute eczema, and chronic eczema based on the disease course. The prevalence rate of eczema in the general population in China is approximately 3%–5%, and that in children is about 10%–20%, making it a relatively common skin disease. Due to the pruritus, erosion, exudation, ulceration, and recurrent attacks of the affected area, eczema seriously affects patients' daily lives.

The Dietary Guidelines for Adult Obesity (2024 Edition) released by the National Health Commission of the People’s Republic of China indicates that the overweight rate and obesity rate among Chinese citizens aged 18 and above reach 34.3% and 16.4%, respectively. Data from the World Obesity Atlas published by the World Obesity Federation shows that the increase rates of adult obesity and childhood obesity in China are 2.8% and 2%, respectively. Based on the current development trend, it is estimated that by 2030, the number of overweight and obese people in China will account for approximately half of the total population.
