This document summarizes a study on healthy habits among 41 primary school pupils aged 9-12 in Poland. The study examined the students' diets, physical activity levels, screen time, sleep habits, and family meal routines through a survey. The results found that the students generally had healthy diets including fruits, vegetables, and dairy, were physically active daily, and ate 3 meals per day with their families. However, they spent a significant time in front of screens for entertainment. The Comenius HETI project increased awareness of how daily habits impact health.
