Sitting all day while studying? Your child’s brain might be suffering – The Times of India

Prolonged sitting and low physical activity during the school day, including long and uninterrupted study sessions, is linked to students’ poorer attention, slower processing and lower academic gains. On the other hand, moving the body in short but purposeful ways during the school day improves on-task behaviour, cognitive performance and learning outcomes. Modern schooling and exam-focused revision often require long stretches of seated study but the brain is embodied and the blood flow, arousal, neurotransmitter dynamics and attention all respond to movement. If students sit for long periods without breaks, they risk reduced vigilance, slower processing and diminished capacity for sustained learning, which are problems that matter the most when the aim is deeper understanding and not just rote hours logged.Physical activity supports children’s cognition. According to a 2016 major systematic review and position stand published in the Medicine & Science in Sports & Exercise revealed that physical fitness, single bouts of PA and PA interventions benefit children’s cognitive functioning. The review also noted that although the effects on standardised achievement tests are mixed, there is consistent evidence that activity improves attention and some executive functions, which are capacities that are essential for learning.

Why sitting too long hurts learning

Practical recommendations for schools and parents

Classroom activity improves on-task behaviour and sometimes achievement. A 2017 meta-analysis of classroom-based physical activity interventions reported positive effects on on-task behaviour and showed evidence that active lessons can improve academic outcomes when implemented well. The authors concluded that classroom physical activity “may have a positive impact on academic-related outcomes.”A potentially effective approach for reducing and breaking up sitting throughout the day is changing the classroom environment. Height-adjustable desks, sit-stand workstations and alternative seating or similar environmental changes reliably reduce sitting time in class with small improvements in attention and reductions in disruptive behaviour. This is likely because standing and frequent posture shifts interrupt the cognitive fatigue that builds during long sitting episodes.As per a 2016 study in Pediatrics, physically active academic lessons significantly improved mathematics and spelling performance of elementary school children. In this classroom intervention, teachers delivered curriculum lessons that integrated movement. Over two years, children in the active-lesson group made larger gains in math speed, general math and spelling than controls, which was roughly equivalent to several months of extra learning. This study showed that movement woven into instruction can both reduce sitting time and boost measurable learning.However, not all activity is equal. The dose, type and timing of activity matter where vigorous exercise immediately before a test can sometimes transiently impair fine motor tasks but brief moderate activity tends to help. Sitting all day for study is an education-era habit that can quietly undermine attention, processing and learning. Break up sitting, weave movement into lessons and pair activity with healthy sleep and limited passive screen time. For parents and teachers the message is simple and low-cost: help your child move more during the school day and their brain will thank you.
