The development and everyday practice of health-conscious behaviour have become increasingly important in contemporary society. In the process of shaping a healthy lifestyle, the enhancement of awareness plays a key role; therefore, it is essential that education promoting regular physical activity and a health-conscious way of life begins at an early age. The aim of the present study was to explore the extent to which health consciousness and the pursuit of a healthy lifestyle are present in the lives of secondary school students in a small town, as well as to examine whether behaviours harmful to health occur in their everyday lives, with particular emphasis on the increasingly popular tobacco products. Furthermore, the study sought to investigate the influence of socialisation contexts, specifically the relationship between family background and willingness to engage in sports, and the impact of online social media applications on regular physical activity. The primary research was conducted using an online questionnaire survey to students in grades 9–11 (n = 69) at Derecske I. Rákóczi György Secondary Grammar School, Technical School, and Dormitory. The survey assessed students’ attitudes toward a healthy lifestyle. The findings indicate that students at the investigated secondary school are familiar with the key components of a healthy lifestyle and strive to incorporate them into their everyday lives. The family, as the primary socializing environment, appears to have a significant influence on their health consciousness. Health-risk behaviors such as smoking, alcohol consumption, and illicit drug use were not characteristic of the respondents. In contrast, the consumption of unhealthy foods, including fast food and sugar-sweetened beverages, was reported to be common among the participants. The impact of the internet and media on sporting habits was found to be substantial, with these factors exerting a predominantly negative influence on adolescents’ willingness to engage in regular physical activity.
