What to Do When There Is a Heatwave | India Emergency Cooling and Family Safety Guide

If there is a heatwave in India, move out of intense heat, reduce physical activity, drink safe fluids appropriately, and check India Meteorological Department warnings for your district. Stay in a cooler, shaded or air-conditioned place when possible, particularly during the hottest hours. Check on infants, older adults, outdoor workers and people with medical conditions before they become unwell.

If someone exposed to heat becomes confused, collapses, has a seizure, develops unusual behaviour or seems seriously ill, suspect possible heatstroke. Call India’s emergency number 112 immediately and begin rapid cooling while help is on the way. Move the person to a cooler place, remove excess clothing, wet their skin with cool or cold water and fan them; use cold packs where available. Do not give drinks to a person who is confused, unconscious or unable to swallow safely. Do not wait to see whether sweating has stopped.

This guide covers practical steps for families, schoolchildren, street vendors, delivery riders, construction workers, outdoor labourers, older residents and visitors across India. It is relevant to hot-season conditions in Delhi, Rajasthan, Uttar Pradesh, Bihar, Odisha, Maharashtra, Gujarat, Telangana, Andhra Pradesh and other regions, while recognising that exposure differs between cities and districts. For current conditions use the India Meteorological Department heatwave guidance and NDMA SACHET alerts. This page is general advice, not a live health or weather bulletin.

Quick answer: what to do during an Indian heatwave

Check your district’s latest IMD heatwave warning. Read the date, affected area, alert colour and suggested actions, not only a screenshot of the temperature.
Stay cooler: seek shaded or air-conditioned space where available, use curtains to block strong sun and minimise strenuous activity during peak heat.
Drink suitable fluids regularly if medically permitted. Use safe water and oral rehydration solutions when appropriate for fluid and salt loss; follow medical guidance if your fluid or salt intake is restricted.
Wear light, loose clothing and protect yourself from sun. Plan unavoidable travel for cooler hours and take frequent breaks.
Watch for heat illness: dizziness, severe weakness, nausea, headache and heavy sweating can be signs of heat exhaustion; move to cool conditions and seek medical evaluation if symptoms are concerning.
Confusion, collapse, seizures or altered consciousness are an emergency: call 112 and cool immediately. Heatstroke may occur with or without sweating.
Never leave a child, elderly person or pet inside a parked vehicle. The interior can become dangerously hot.
Check neighbours and family members who are isolated, especially if their homes stay hot at night or electricity has failed.

India’s Emergency Response Support System confirms that 112 is the national emergency assistance number. The National Centre for Disease Control’s community heat-illness manual explains prevention and first-aid priorities; the World Health Organization heatwave guide stresses emergency referral and cooling for heatstroke.

What is a heatwave in India?

A heatwave is not simply a day on which the thermometer reaches an uncomfortable number. The India Meteorological Department considers temperatures in relation to regional norms and uses specified thresholds and departures from normal in its heatwave definitions. A temperature that is unusual and dangerous in one district may be more commonplace elsewhere.

IMD’s Heat Wave FAQ explains how heatwave criteria vary between plains and hilly locations and how district-level warnings are communicated. But the most useful question for a reader is not whether a particular threshold has just been met. It is how much heat your body is absorbing, whether it can release that heat, and whether you can get to a cooler setting.

High humidity makes sweating less effective at cooling the body. Direct sun, work intensity, dark roofs, poor ventilation, lack of water and hot nights can make conditions more difficult. Even a city that is not under a severe heatwave warning can have dangerously hot rooms or exposed workplaces.

The official warning is therefore a decision aid, not permission to ignore symptoms below some arbitrary temperature.

Read the IMD warning for your district, not another state’s forecast

India is too large for a single national temperature headline to describe every resident’s risk. IMD publishes district-level weather and heat-impact guidance, including colour-coded warnings and updates. The latest bulletin may include the likely intensity, duration, vulnerable populations and recommended action.

Open IMD’s heatwave page, look for the applicable district and identify the date and issue time. A forwarded graphic from yesterday may no longer be current. Someone in Rajasthan should not assume that an alert issued for coastal Odisha describes their conditions, and someone living in a densely built urban neighbourhood may experience a very hot room even if a nearby regional station records a lower value.

The government SACHET disaster alert portal distributes geographically targeted alerts through official channels. Check that an SMS or message is genuine and applies to your locality. Do not forward an anonymous claim that all schools, factories or markets are closed unless the responsible authority has actually issued that order.

India’s official impact-based warnings exist to support decisions about working hours, school activities, public facilities and healthcare readiness—not merely to attract attention with a colour. For a particular closure or changed schedule, consult the school, employer, local government or district administration responsible.

Why heat can become a medical emergency

The human body needs to keep its internal temperature within a narrow safe range. It releases heat partly through the evaporation of sweat and by moving heat toward the skin. When the environment is very hot or humid, when exertion is heavy or when dehydration reduces cooling capacity, the body can struggle to keep up.

Heat illness can begin with thirst, headache, cramps, nausea, weakness or dizziness and can progress. Heatstroke is the most serious end of this range, involving dangerous heat stress and often neurological symptoms such as confusion, seizures or loss of consciousness. It can injure organs and become fatal without urgent cooling and medical care.

An important misconception is that a person with heatstroke must have stopped sweating. That is not reliable. People with exertional heatstroke may still be sweating heavily. The CDC’s clinical and occupational guidance lists both hot dry skin and profuse sweating as possible findings.

Do not wait to measure an exact body temperature, identify the cause of every symptom or complete an online questionnaire before calling for emergency help when severe symptoms appear. The first priorities are emergency contact, rapid cooling and safe monitoring.

Heat exhaustion versus heatstroke: the action changes

Heat exhaustion: move, cool, rest and assess

A person with heat exhaustion may have heavy sweating, weakness, headache, dizziness, nausea, thirst or irritability. They may be able to speak normally but feel exhausted and unsteady. Move them to shade or an air-conditioned space, stop physical activity, loosen excess clothing and cool their skin with water and air movement.

If the person is fully alert, able to swallow and not vomiting, they may take slow sips of cool water or appropriate oral rehydration solution, subject to medical restrictions. Stay with them and obtain medical evaluation if symptoms are significant. If vomiting, fainting, worsening symptoms or failure to improve occurs, get urgent medical assistance.

Do not send the person straight back to a construction shift because the headache has eased after ten minutes. Heat illness can recur or progress, especially if the environment and exertion remain the same.

Heatstroke: call 112 and cool without delay

Suspect heatstroke if a heat-exposed person becomes confused, incoherent, collapses, experiences seizures or is seriously unwell. Call 112 immediately. Send a bystander to obtain help while another person begins cooling, if possible.

Move the person to shade or a cooler area if this can be done safely. Remove unnecessary clothing. Pour or spray cool or cold water over the body, use wet cloths and fans, and apply cold packs around areas such as the neck, armpits and groin. Where safe, feasible and appropriate, more intensive cold-water cooling may be used under trained guidance.

Do not give fluids orally to someone who is confused, unconscious, seizing or unable to swallow safely. Do not give aspirin or paracetamol to treat the heatstroke itself; they do not replace urgent cooling. If the person is unconscious but breathing normally, place them safely on their side if appropriate and monitor breathing. Follow emergency-dispatch instructions; if not breathing normally, initiate CPR if trained and instructed.

The NCDC’s emergency cooling guidance emphasises that heatstroke treatment is time-sensitive. Cooling is not something to postpone until transport arrives.

How to cool a person safely while waiting for help

The goal is to remove body heat quickly without delaying the ambulance or creating a new injury. Use the resources already available in the setting: shade, a fan, clean water, cool towels, a wet sheet or cold packs. If several people are present, divide the work: one calls, one cools, and one prepares location details and access for responders.

Move the person away from hot machinery, a rooftop, a sunlit vehicle or an exposed roadside if they can be moved without causing more danger. Keep the airway clear and follow emergency-dispatch guidance. Do not force drinks or tablets into the mouth of an unresponsive person.

If a cold-water bath or immersion method is being considered, ensure the person cannot slip beneath water or lose airway protection; such methods may require trained oversight depending on condition. Cooling by dousing the body and fanning is often more immediately available to a family or workplace.

Avoid focusing on one technique as if it were the only valid response. Call early and begin effective cooling with whatever safe equipment is immediately available. The WHO guidance explicitly recommends rapid cooling and continued monitoring while emergency medical assistance is arranged.

Water, ORS and hydration: what helps and what needs caution

Many people lose substantial water and salt through sweating in hot weather. Regular access to safe drinking water is important, and oral rehydration solutions can be useful in appropriate situations involving fluid and salt loss. However, “everyone should drink as much water as possible” is not a safe medical rule.

People with kidney disease, heart failure or medical fluid restrictions may require individualized advice. Drinking very large amounts of plain water during prolonged exertion can also be unsafe. Workers should receive suitable breaks, hydration and health guidance rather than being pushed to drink excessive amounts while continuing intense labour.

For infants, continue age-appropriate feeding and seek professional advice rather than replacing breastmilk or formula with plain water for a young baby. For adults who are alert, safe water taken regularly is a practical starting point; avoid alcohol and do not rely on large amounts of highly caffeinated drinks as a substitute for hydration.

A person who is vomiting, severely confused or unconscious should not be given oral fluids. In that situation the priority changes to urgent medical care and cooling. Hydration prevents some illness; it does not cure severe heatstroke on its own.

Make the home cooler before the hottest part of the day

Indoor heat can become hazardous when a roof and walls absorb sun all afternoon and release warmth after sunset. Blocking sunlight early may help: close curtains or blinds on sun-exposed windows, use shading where practical and reduce unnecessary heat-producing appliances.

Ventilation depends on conditions. If outside air is cooler than the home, opening windows may help. If outside air is much hotter, bringing in that air can worsen conditions. Fans can make people feel cooler by moving air across the skin, but a fan alone may be insufficient in very hot rooms, particularly for vulnerable people.

Where possible, spend part of the day in a demonstrably cooler community setting, shaded facility or air-conditioned space. Never stay inside a sealed room that becomes dangerously hot just because a fan is running. If electricity fails, identify a safe accessible location with cooling and communicate that plan to family.

The NCDC’s community heat-prevention training manual discusses shading, timing ventilation, cooling the skin and adapting daily activities. A household can make meaningful changes without expensive equipment, but no single inexpensive trick is a guarantee against severe indoor heat.

If there is a power cut during a heatwave

An outage removes fans, some water-pumping systems, refrigeration and air conditioning simultaneously. The first decision is whether your home will remain safe for everyone who lives there. People who are older, ill, disabled, pregnant or caring for infants may need an alternative cooled location sooner.

Reduce indoor heat generation; avoid unnecessary cooking that warms the room further. Use safe water, lightweight clothing and wet cloth cooling where practical. Check official electricity and public-health updates. If the room becomes extremely hot, consider relocation to an official cooling facility or a trusted cooler home before the person becomes ill.

Do not run an outdoor petrol or diesel generator inside a home, balcony enclosure, stairwell, shed or near windows. Fuel generators can create deadly carbon-monoxide exposure. A power cut is not an excuse to substitute a new poisoning hazard for heat.

If medicine requires refrigeration or medical equipment needs power, contact the healthcare provider, pharmacy or emergency service for safe continuity arrangements. Do not guess whether a temperature-sensitive medicine remains usable after a long outage.

Outdoor workers: a heatwave is a workplace safety problem

Construction workers, agricultural labourers, street vendors, cleaners, traffic personnel, delivery riders and outdoor maintenance staff can face heat from both weather and physical effort. Helmets, uniforms and protective clothing may add to heat strain. The solution must involve work organisation, not merely telling workers to “be tough.”

Work should be reviewed against official heat alerts and occupational safety policies. Where possible, schedule strenuous tasks during cooler hours, provide accessible shade, safe drinking water, rest breaks and a realistic way to stop work when someone feels unwell. New or returning workers may need gradual adjustment to hot conditions.

Supervisors should ensure workers know which signs require immediate rest and which require an emergency call. A colleague who is suddenly confused should not be told to drink water alone and finish the shift. Assign someone to call 112 while others begin cooling.

The CDC’s heat-stress illness guidance provides a useful supplementary clinical framework. In India, comply with state, employer and local government requirements; exact work-hour orders can vary and should not be invented from a national blog article.

What a supervisor should say before a hot shift

A useful briefing takes less than a minute: “Here is today’s local warning. Here is the cooler rest area. Water is available here. Tell someone immediately about dizziness, nausea or weakness. If a colleague becomes confused or collapses, call 112 and start cooling. Nobody will be left alone with severe symptoms.”

Then the supervisor must make the instructions possible. A rest point is not useful if a worker cannot leave a scaffold, rooftop or field. A water tap on another floor may not be a workable hydration arrangement. A warning poster is not an alternative to reducing exertion and organising relief.

Check on workers who may be embarrassed to report symptoms, who speak a different language or who are paid per delivery. A pay structure that rewards skipping breaks can undermine safety. Use trusted bilingual communication and make the emergency route clear.

Finally, observe whether the plan works. If people repeatedly become dizzy or overheated, revise the shift and protection measures rather than waiting for a severe event to prove that the system was inadequate.

Schools, examinations and outdoor sports

Schools must follow their state’s or district’s current instructions about heat advisories, changed schedules or closures. Do not infer that every Indian state will close schools on the same temperature. At the household level, make sure children can drink safe water, access shade and communicate symptoms.

Outdoor physical education and sport may require modification or cancellation during dangerous heat. An organised team should have someone responsible for monitoring conditions and first aid. A child who becomes unsteady, confused or collapses needs immediate care, not simply a reminder to rest until the next practice.

For examinations, avoid forcing children to wait for long periods in an exposed outdoor queue where there is no shade or water. Schools and centres should provide appropriate access while following exam administration rules. Parents should check official school communications rather than circulating an unverified holiday announcement.

If a child returns from school dizzy or nauseated after heat exposure, move them to a cool place and assess carefully. Severe or concerning symptoms warrant medical attention. Do not assume every headache is ordinary tiredness.

Infants and young children during a heatwave

Babies and young children rely on adults to recognise discomfort and ensure appropriate cooling and feeding. Dress them in suitable light clothing, keep rooms cooler, use age-appropriate hydration or feeding, and avoid unnecessary outings during the hottest hours.

A sleeping infant should never be left in a parked car, even for a few minutes, and should not be left unattended on a sun-exposed balcony or rooftop. Car interiors can heat rapidly, and a partially opened window is not a reliable safety measure.

Watch for unusual lethargy, irritability, poor feeding, reduced urine output, vomiting or signs of serious illness. Contact a healthcare professional when concerning symptoms appear; sudden confusion, collapse, seizures or severe unresponsiveness require emergency assistance.

Choose shade and safe ventilation without creating suffocation hazards. Heavy wet coverings over a pram can restrict airflow and trap heat. Keeping the child cool is the purpose, not merely keeping sunlight off their face.

Older adults and people living alone

An older person may experience high indoor heat without noticing thirst as strongly or being able to reach a cooler place. Some medicines and chronic illnesses can affect heat tolerance. A person may also avoid using air conditioning because of electricity costs or be unable to operate equipment during an outage.

Arrange simple regular check-ins during an alert: ask how hot the room feels, whether the person has access to water, whether medication is available and whether they can move to a cooler area. If they seem confused or cannot answer simple questions normally, do not end the call and hope they feel better later.

A trusted neighbour can help with safe supplies, but community checks should not involve untrained people moving a seriously ill person without emergency guidance. Arrange an accessible destination and transportation before weather becomes more severe.

For people with cognitive or sensory disabilities, use clear instructions, accessible notices and a familiar contact plan. Risk follows the person’s environment and ability to respond, not just their age on paper.

People with heart, kidney or respiratory conditions

Heat can place extra stress on the body, especially when hydration, medicines and underlying illness interact. But generic health advice should not override a patient’s existing treatment instructions. Someone with a fluid restriction should not automatically be told to double their drinking volume.

Ask a doctor or pharmacist whether any medication affects fluid balance, heat tolerance or storage requirements. Do not stop medication on your own. Prepare a plan for obtaining refills if travel becomes difficult and for keeping temperature-sensitive medicines safe during power cuts.

If symptoms such as chest pain, fainting, breathing difficulty, confusion or severe weakness occur, seek urgent medical attention. Heat exposure may be one part of the problem, but an emergency responder must assess all possible causes.

A household can protect vulnerable people by choosing the coolest available location, reducing exertion, making water available under medical guidance and planning help before a crisis. These are practical actions, not a claim that home adjustments can treat every illness.

Travelling in India during a heatwave

A summer journey can combine long queues, traffic, crowded platforms, exposure to sun and limited drinking water. Check IMD’s warning for the districts along your route and consider rescheduling nonessential travel. If travel is necessary, carry water, a hat or umbrella, medicines and a plan for shaded breaks.

Do not plan a walking tour of markets, forts or exposed monuments solely around what looks convenient on a map. Outdoor stone and pavement surfaces can become extremely hot. Find realistic cooler stops and transport options. Avoid leaving companions waiting in unshaded parking areas.

Check elderly travellers and young children frequently. A person who starts to feel dizzy should be taken to a cooler safe place, not urged to finish the journey. If serious symptoms occur, call 112 and provide a clear landmark.

A train or bus running on schedule does not guarantee a comfortable or safe waiting environment. The transport decision and personal health decision are related but separate.

Heatwaves in cities versus rural areas

In cities, dark roofs, dense construction, limited shade and heat from vehicles can keep some neighbourhoods hot after sunset. Someone living on a top floor under a metal roof may face a different indoor heat problem from a person in a shaded ground-floor apartment.

In rural settings, agricultural work, long walks for water and limited electrical cooling can create significant exposure. A person who works in a field may be hundreds of metres from reliable shade or a safe drinking source. A plan that depends on returning to the house every time the worker feels sick may be inadequate.

Neither setting is inherently safe. The common questions are: Where can people cool down? Is safe drinking water available? Is strenuous work reduced during dangerous conditions? Can an unwell person reach medical help promptly?

The most effective response often combines individual precautions with community action: shade, water access, sensible scheduling, communication and a reliable emergency route.

What should a shopkeeper, driver or street vendor do?

People whose income depends on staying outdoors may find it difficult to follow a simple instruction to remain at home. The goal is to reduce exposure as far as realistically possible. Consider earlier or later work hours where permitted, temporary shade, accessible water, frequent breaks and rotation with another worker.

A street-food vendor also needs safe food storage in high temperatures, not just personal hydration. A delivery rider should avoid skipping breaks under pressure to finish orders. A driver should never leave children or vulnerable passengers in a parked vehicle, even with windows partly open.

Supervisors and business owners should recognise that visibly unwell workers may need immediate help and that customers may also be at risk in long queues. Offering a shaded waiting area and water access is not a substitute for medical care, but it can reduce avoidable exposure.

A heatwave response that works only for people with air-conditioned offices leaves many vulnerable workers without a practical plan. Readers should adapt the protective principle to their work setting rather than pretending that all workplaces have the same resources.

Daytime heat and hot nights: why recovery matters

The body needs opportunities to release accumulated heat. Very hot nights may reduce recovery, particularly when a home retains heat and residents cannot sleep comfortably. After several hot days, a person may become progressively fatigued or dehydrated.

Check the temperature and ventilation of the bedroom, not just the daytime outdoor forecast. Arrange for vulnerable household members to sleep in the coolest safe part of the home, or relocate temporarily if the home remains dangerously hot.

Do not rely on a fan alone if it simply circulates unbearable heat. If opening a window introduces cooler air, it may help; if the outdoor air is hotter or heavily polluted, the decision needs adjustment. Use public-health and local weather guidance rather than a universal ventilation rule.

If someone develops confusion, severe weakness or collapse overnight, treat it as a potential emergency, not as ordinary poor sleep. Heat illness is not confined to noon.

Heatwave preparedness for a household with limited resources

Preparation need not begin with expensive purchases. Identify the coolest accessible place in the building, safe water sources, nearby public facilities with cooler air, the nearest medical service, and the person who will help someone unable to travel independently.

Before a warning period, check whether curtains or shading can reduce direct sun. Make sure working fans, containers for safe drinking water, a charged phone and essential medications are available. Plan cooking to minimise indoor heat buildup where safely possible.

Agree on household roles. One adult checks official IMD alerts; another contacts an older family member; someone ensures that children and outdoor workers have access to water and shade. Assign a backup if the usual adult is away.

If the home loses power, have a specific alternative rather than a vague plan to “manage somehow.” A trusted community facility, family home or public building may be safer if its cooling and accessibility have been confirmed.

Worked example 1: a construction worker becomes confused

Imagine a construction worker on a rooftop during a very hot afternoon. Earlier they felt weak and nauseated, but continued working. Now they speak unclearly and cannot follow simple instructions. A coworker proposes that they sit beside a fan and drink a large bottle of water.

The safer response is to recognise possible heatstroke. Another worker calls 112, while the team moves the person to a cooler safe place and begins rapid cooling with water and airflow. They do not force liquids into a confused person’s mouth. Someone stays with the worker until emergency personnel arrive.

This is a fictional teaching scenario, not a report of a particular workplace event. It demonstrates the decision change from preventing heat illness to responding to a life-threatening emergency.

Worked example 2: an older resident during an evening power cut

Imagine an older woman living on the top floor of an apartment during prolonged heat. The electricity fails in the evening and the room stays hot. A neighbour notices that she has not eaten and is becoming unusually tired.

The neighbour contacts a trusted relative and helps arrange access to a cooler safe place before symptoms become severe. They also check medicine needs and transport. If she becomes confused, collapses or is unable to respond normally, they call 112 and begin cooling while waiting for help.

The lesson is that indoor heat is real exposure, even when someone is no longer standing in the sun. A good plan identifies the safe alternative before a medical emergency develops.

Worked example 3: a family travelling across districts

A family plans a daytime road journey through several states. They check an IMD heatwave map and find that one stretch has a more severe warning than their home district. Rather than relying on a national weather headline, they shift departure to cooler hours and plan safe shaded stops.

They carry safe water, medications and age-appropriate supplies for a young child. At a roadside stop, the child appears unusually lethargic, so they move to a cooler environment and seek medical assessment rather than pressing onward to meet a schedule.

This fictional example shows why a good travel plan checks the hazard along the route, not just conditions at departure or destination.

Worked example 4: a school changes outdoor activity

A school in a heat-alert district has scheduled afternoon sports practice. Staff check current official warnings and revise the activity plan, keeping children out of intense exposed conditions. They also ensure water access and a straightforward way to report symptoms.

When a student becomes dizzy, staff stop activity, move the child to a cooler safe space and monitor the situation. If severe neurological symptoms appear, they call emergency services rather than waiting for a parent to arrive. The school informs families through official communication.

The lesson is not that every warm day requires cancellation; it is that activity, exposure and the available safety response must match the actual warning and conditions.

Common mistakes during heatwaves

“If someone is sweating, it cannot be heatstroke.” Heatstroke can occur with continued sweating; severe neurological symptoms matter.
“Give an unconscious person water.” That can cause choking or aspiration. Call emergency services and cool.
“Wait for an exact temperature reading before helping.” Severe symptoms require urgent action even when no thermometer is present.
“A fan always makes any room safe.” In extreme indoor heat, moving hot air may be insufficient; find a cooler setting.
“Everybody should drink unlimited water.” Medical restrictions and excessive fluid intake can make this unsafe.
“Take fever medicine to lower heatstroke temperature.” Aspirin and paracetamol do not replace rapid cooling and emergency care.
“Nighttime must be safe because the sun has set.” Hot buildings can retain heat and reduce recovery.
“A child can wait in a parked car for a short time.” Vehicle interiors can become dangerously hot quickly.
“The district forecast is not red, so heat cannot harm anyone.” Personal exposure and symptoms still matter.
“A worker has rested for ten minutes and can return immediately.” Serious or persistent symptoms require medical assessment.

Frequently asked questions

What is India’s emergency number for a person with suspected heatstroke?

112 is the national emergency assistance number. Call immediately for confusion, collapse, seizures or other severe heat-related symptoms, and start cooling while help is on the way.

Should I give ORS to someone who has heatstroke?

Do not give oral fluids if the person is confused, unconscious or unable to swallow safely. Emergency medical attention and rapid cooling take priority.

Can heatstroke occur if the person is still sweating?

Yes. Some people with heatstroke, particularly after heavy exertion, may sweat profusely. Do not use sweating as a test to rule it out.

What if I have kidney disease or a fluid restriction?

Follow your clinician’s advice for hydration and medication. Do not increase fluid or salt intake arbitrarily; arrange early medical advice about heat protection.

Can a heatwave affect someone indoors?

Yes. Hot roofs, poor ventilation, high humidity and power cuts can create dangerous indoor heat, particularly for vulnerable people.

Where can I check heatwave warnings for my city or district?

Use the India Meteorological Department and the NDMA SACHET portal for current official information.

Is heat exhaustion the same as heatstroke?

No. Heat exhaustion requires stopping exposure, cooling, fluids when safe and medical evaluation when appropriate. Heatstroke is a life-threatening emergency requiring immediate emergency contact and rapid cooling.

Should schools always close above one specific temperature?

Follow current state, district, school and government directions. A single generic temperature cannot capture local weather, exposure and institutional policies.
