The Silent Epidemic in the Classroom<\/strong><\/p>\nStudies over the past decade have shown a disturbing trend: Indian children are getting heavier, more sedentary, and more prone to metabolic diseases at younger ages. According to the Indian Council of Medical Research (ICMR), nearly one in ten school-aged children in urban India is overweight or obese.<\/p>\n
Many show early signs of insulin resistance \u2013 a prelude to diabetes and doctors say the age of onset is falling rapidly. Physical inactivity is the biggest culprit.<\/p>\n
The World Health Organization recommends at least 60 minutes of moderate to vigorous physical activity daily for children, but most Indian schools provide barely a fraction of that. Between long classes, exam pressure, and tuition after hours, movement has been reduced to a luxury.<\/p>\n
Nutrition expert Sheetal Yadav from Bengaluru explains, \u201cInsulin resistance and childhood obesity form a vicious cycle. Long study hours, extra classes, and app-based games are pushing kids toward inactive lifestyles. The fat cells that form in childhood stay for life, which is why it\u2019s much harder to reverse obesity later.\u201d<\/p>\n
Cancelled PE, Cancelled Health<\/strong><\/p>\nA generation ago, children ran in open fields, cycled to school, and climbed trees. Today, they spend most of their waking hours sitting at desks, in vehicles, or in front of screens.<\/p>\n
In many private schools, Physical Education is squeezed into a single weekly session. And when exams approach or the syllabus lags, it\u2019s the first period to be sacrificed.<\/p>\n
The consequences are physiological as well as psychological. The less children move, the less efficiently their bodies handle glucose. The energy meant for muscles is stored as fat instead. Over time, this leads to insulin resistance \u2013 a metabolic condition that sets the stage for diabetes, high blood pressure, and heart disease.<\/p>\n
The problem compounds when schools lack playgrounds altogether. Urban land prices and space constraints have pushed newer institutions into vertical buildings where outdoor space is minimal. For many students, their only exposure to movement is the walk between classrooms.<\/p>\n
The Dopamine Trap: How Screens Replace Play<\/strong><\/p>\nTechnology has deepened this crisis. Children no longer run outdoors for entertainment, they scroll. Social media, gaming apps, and streaming platforms now deliver what the brain interprets as \u201crewards,\u201d but without the physical engagement or community connection that outdoor play once provided.<\/p>\n
Dr. Alok Kulkarni, Senior Consultant Psychiatrist at Manas Institute of Mental Health, Hubballi, explains: \u201cOur culture now normalizes sitting for hours in front of screens. Adults do it constantly, so kids follow. Earlier, people interacted with their community; now children don\u2019t even know what that feels like. Easy dopamine from screens has reduced their attention spans. They get bored of one video and immediately jump to the next.\u201d<\/p>\n
He adds that this constant stimulation, combined with the consumption of ultra-processed foods, \u201chijacks the brain\u2019s dopamine system.\u201d \u201cChildren develop impulsive behaviour.<\/p>\n
What starts as casual screen time during meals, often introduced by parents becomes a habit that hardens into addiction. We now have a defined psychiatric condition called internet gaming disorder,\u201d he warns.<\/p>\n
Dr. Kulkarni insists that awareness must begin at home: \u201cAdults should first reduce their own screen use, especially in front of kids. It has to start early, even before age one. We also need national-level programs to reconnect children with community spaces and schools.\u201d<\/p>\n
A Culture That Sits Too Much<\/strong><\/p>\nIndian children are not missing out on play because they\u2019re being forced to study, they\u2019re missing out because their world has shrunk. School buses replace walking, tuition replaces outdoor games, and mobile screens replace neighbourhood cricket. Even in households that can afford sports academies, exercise is often seen as an extracurricular privilege rather than a daily necessity.<\/p>\n
But the human body was built to move. Regular physical activity improves not only muscle and bone health but also cognitive development and emotional balance. Studies have shown that physically active children perform better academically, focus longer, and have fewer behavioural problems than their sedentary peers.<\/p>\n
Why Schools Must Take Responsibility<\/strong><\/p>\nExperts argue that reversing this health crisis starts within school walls. Every institution, public or private should guarantee dedicated time and infrastructure for play. PE classes should be non-negotiable, not optional.<\/p>\n
