Every year, as May turns to June, Pakistani schools face the same question and answer it differently every day: is it too hot for the children to play outside? One school cancels outdoor break entirely and keeps a thousand restless children indoors for a month. Another changes nothing, and children run football practice on a concrete ground at 1 pm in 44-degree heat. Both are failures of planning, not of care. Heatwave break-time rules exist to replace daily guessing with a policy: at what temperature outdoor play changes, what changes, and who decides. Children are not small adults in heat — they warm up faster, sweat less efficiently, and will not stop playing because they feel ill; they stop when an adult tells them to, or when they collapse. That is why the rules must come from adults, in advance, in writing.
The good news is that a heatwave break policy costs almost nothing. It needs shade, water, a thermometer or a reliable weather reading, a timetable adjustment, and the willingness to tell parents plainly what the school is doing and why. It does not need air-conditioning in the playground or expensive equipment. What it does need is consistency: the policy must apply on the first hot day and the fortieth, when everyone is tired of it, because heat illness does not care that the school is used to the heat by June. This guide sets out the risks, a temperature-based policy any principal can adopt, the shade-water-rest routine that makes play safe, the warning signs every duty teacher must recognise, and the parent message that turns a restriction into a trust-builder.
Why Heat Hits Schoolchildren Harder
Children produce more body heat per kilogram than adults when they run and play, and they cool themselves less efficiently, because their sweat glands are still developing and their body surface area relative to their mass is larger, so they absorb heat from hot air and hot surfaces faster. A child playing hard in direct sun can reach a dangerous body temperature far sooner than the adult watching from the shade realises, and children are poor judges of their own heat stress: they are absorbed in the game, they do not want to be the one who stops, and thirst lags behind actual water need. Younger children are at greatest risk, followed by children who are unwell, overweight, or not used to the heat after a holiday, and by any child playing a competitive game where stopping feels like letting the team down. Duty teachers should watch the quiet child sitting down suddenly, not only the loud ones still running.
The surfaces matter as much as the air. A concrete or asphalt playground in Pakistani summer can be far hotter than the air temperature, radiating heat upward into children playing centimetres above it, and metal equipment — slides, swing chains, climbing bars — can burn skin on contact by late morning. Dark school uniforms absorb more heat than light ones, and a child who has walked to school in the sun, eaten a small lunch and drunk little water arrives at break already partly dehydrated. None of this means children must never play in summer; it means the school must manage heat the way it manages any other risk — by measuring it, limiting exposure, and providing water and shade as deliberately as it provides supervision. The school's heatstroke prevention work and its break-time rules are the same plan, not two plans.
A Temperature-Based Play Policy
A policy that says "play is cancelled when it is very hot" is not a policy, because nobody agrees what very hot means at 7:30 in the morning. Use bands, based on the day's forecast maximum or a shaded thermometer reading at the school, and announce which band the day falls in before first break. A practical set of bands for most Pakistani schools: below 35°C, normal outdoor play with water available; 35–39°C, outdoor play shortened and restricted to shaded areas, with no vigorous games or sports practice in direct sun; 40°C and above, no outdoor play at all — break moves indoors or to fully shaded verandas, and sports practice is postponed or moved to early morning. Schools in Jacobabad, Sibi, Larkana and other extreme-heat districts should set their thresholds a degree or two lower in practice, because humidity and ground heat make the same air temperature harder there, and schools should use the "feels like" temperature when humidity is high.
Timing is the other lever, and it is free. Move break earlier in the day during heatwave weeks, so the main break falls before the worst heat rather than at noon, and move sports practice and physical education to the first period or after the heat eases, never to the middle of the day. Shorten outdoor break from, say, thirty minutes to fifteen or twenty in the middle band, and use the remaining time for a calm indoor activity — reading, drawing, or a quiet game — so children still get a real break rather than a truncated one that leaves them frustrated. The timetable change should be announced for the whole heatwave week, not day by day, because parents, teachers and students all plan better around a stable week than around a daily surprise. A school that already adjusts timings for summer, as described in guidance on summer timing changes, can fold the heat bands into that same announcement.
The Heat Bands
Shade, Water and Rest: The Three Non-Negotiables
Shade first. Audit the playground for shade at midday, not at 8 am, because morning shade and noon shade are different places. If the only shade is a narrow strip along one wall, that strip becomes the play area in the middle band, and games are chosen to fit it — skipping, catch, board games on mats — rather than cricket or football that need the open ground. Where shade is scarce, create it cheaply: a shamiana or canvas sheet strung between poles over part of the ground, a few large umbrellas at duty points, or permission for classes to use shaded verandas as their break area on rotation. Planting trees is the long-term answer, but a school cannot wait for a sapling to grow while this June's children play in the sun; temporary shade this week beats a tree in ten years, and both should be pursued.
Water second, and scheduled rather than left to chance. Children do not drink enough voluntarily during play, so build water breaks into the break itself: in the middle band, the duty teacher calls a water break halfway through outdoor time, and every child drinks before resuming play. Check that water points actually work — coolers filled, filters maintained, cups or bottles available — because a water rule without working water is a slogan. Children should be encouraged, and younger ones required, to bring a filled water bottle from home, and the school should keep a small stock of clean cups and a spare cooler for children who forget. Rest third: in the middle band, no child plays vigorously for the whole break without a pause, and any child who looks flushed, unusually quiet or unsteady is brought into the shade to sit, drink and be watched, without embarrassment and without being sent straight back out. Clean, cool drinking water is the foundation of all three rules, and its maintenance is a summer duty, not an afterthought.
Heatstroke Warning Signs Every Duty Teacher Must Know
Every duty teacher should know the ladder from heat exhaustion to heatstroke, because early recognition is the difference between a child who recovers in the shade and a child who needs an ambulance. Heat exhaustion signs: heavy sweating, weakness, cold or clammy skin, nausea, headache, dizziness and faintness. The response is immediate shade, lying down with legs slightly raised, loosening clothes, sips of cool water, and cooling with a wet cloth — and the child does not return to play that day. Heatstroke signs are more alarming: body temperature above 40°C, hot and red skin that may be dry, confusion, slurred speech, throbbing headache, rapid pulse, vomiting, or loss of consciousness. Heatstroke is a medical emergency: call for help and the school nurse or nearest clinic at once, move the child to the coolest place available, cool aggressively with wet cloths and fanning while waiting, and do not give fluids to an unconscious child.
Three practical preparations make this knowledge usable rather than theoretical. First, every duty teacher in summer carries, or knows the location of, the nearest first aid point and the school's emergency phone numbers — not in a file in the office, but on the duty sheet itself. Second, the school runs a ten-minute briefing at the start of the hot season, in which the nurse or a trained teacher walks duty staff through the signs and the response, because a sign recognised in training is recognised faster on a playground. Third, the school keeps a simple log of heat incidents — date, child, symptoms, action, parent informed — so patterns emerge: if three children from the same class are affected in a week, the problem may be that class's timetable, its classroom's heat, or its water access, not individual weakness. Heat illness records feed directly into the school's emergency plan, which should name the nearest hospital and the transport arrangement for a heat emergency before one happens.
Telling Parents What Has Changed — and Why
Parents accept restrictions they understand and resist restrictions that arrive unexplained, especially when a child comes home saying "we were not allowed to play." Send one clear WhatsApp message at the start of the hot season, in Urdu and English if the school's parents need both, stating the heat bands, what each band means for break, and what parents should send: a filled water bottle daily, a cap or hat, light clothing under the uniform where the school allows it, and a note to the class teacher if the child has a condition affected by heat, such as asthma or a heart condition. Ask parents to keep an unwell child home on extreme-heat days rather than sending them to sit in a hot classroom, and say plainly that the school will move break indoors at 40°C without waiting for permission — parents who hear this in advance support it, while parents who first hear it from an upset child do not.
Keep parents informed during a heatwave week, not only at its start. A short morning message — "Today is a 41°C day: indoor break, water bottles essential, sports practice postponed" — takes a minute and prevents a hundred questions. When the school does keep children indoors for several days, acknowledge the cost honestly: children miss active play, and the school is compensating with indoor games, library time and early-morning activity where possible, rather than pretending indoor break is just as good. Honesty builds the trust that makes the next restriction easier, and it also invites help — parents who understand the shade problem may donate a shamiana, a cooler, or trees for the ground. A heatwave policy that parents helped to support is a policy the school can actually enforce on the hottest, hardest days, when enforcement matters most.
