Initial advice focused on recovery from common colds, emphasizing the need for rest, hydration, and reduced physical strain. Nutritionists also highlighted the importance of students avoiding skipped meals by incorporating snacks like fruits or nuts to maintain energy levels during school hours. Subsequent guidance expanded to include preventive medical care. Specialists recommended clinical reviews and laboratory tests to identify issues such as anemia or vitamin deficiencies that can cause fatigue. Furthermore, the importance of breakfast for cognitive performance was emphasized, with experts suggesting nutrient-dense options like oats to support attention and memory. Recent expert advice emphasizes that the transition back to strict schedules can cause physical and metabolic imbalances. Dr. Andrea Odreman of Grupo Médico Santa Paula recommends comprehensive clinical reviews, including hematology and lipid profiles, to detect silent pathologies like metabolic alterations. To support cognitive function, nutritionists suggest planning meals in advance and combining oats with fruits, eggs, or yogurt. As school years begin, specialists such as Kalliopi Georgakouli of the University of Thessaly note that dietary consistency is more important than perfection. New Greek Ministry of Health guidelines for school canteens aim to remove processed meats, chips, and soft drinks, aligning with World Health Organization recommendations to limit free sugars to under 10% of daily energy intake. Experts also warn that persistent fatigue may be linked to low iron levels, and they highlight vitamin D deficiency as a concern for those with indoor lifestyles, suggesting a daily intake of 400 IU for bone health. With the onset of the autumn school season, experts suggest following a Mediterranean diet to manage stress and fatigue. ## Timeline ### 2026-09-21: Health advice for students returning to school routines Health experts offer advice for the back-to-school season, focusing on balanced nutrition, managing sugar intake, and monitoring iron and vitamin D levels to combat fatigue and support development. 3 sources. https://clstr.news/cluster/health-advice-for-students-returning-to-school-routines ### 2026-09-21: Nutrition and dietary habits during the autumn school season Seasonal transitions and the return to school highlight the importance of balanced nutrition, focusing on Mediterranean diet staples and the role of school dining halls in establishing healthy habits. 3 sources. https://clstr.news/cluster/nutrition-and-dietary-habits-during-the-autumn-school-season ### 2026-09-16: Health experts advise preventive care and nutrition for routine transitions Health experts recommend preventive medical check-ups and nutritious breakfasts, such as oats, to support cognitive performance and physical well-being during the return to school and work routines. 5 sources. https://clstr.news/cluster/health-experts-advise-preventive-care-and-nutrition-for-routine-transitions ### 2026-09-14: Health advice focuses on cold recovery and student nutrition Health experts advise prioritizing rest during colds and emphasize the importance of regular snacking for students to maintain energy levels during the school day. 2 sources. https://clstr.news/cluster/health-advice-focuses-on-cold-recovery-and-student-nutrition --- Cite as: Health and nutrition guidance for routine transitions.
