Heatwaves: a practical plan for staying safe

A heatwave plan should cover a cool place to go, access to fluids, support for vulnerable people and the signs of serious heat illness. Medicines and existing conditions may require individual advice. Confusion, collapse or severe illness in the heat can be an emergency: call 000 and begin cooling while following emergency instructions.

Plan around the person and the place

Heat affects people differently depending on health, age, activity and access to cooling. Think about the home, workplace, transport and time outdoors, rather than only the forecast temperature. Healthdirect's hot-weather guidance explains heat-related illness and the importance of preparation.

Identify which part of the day or setting is hardest to manage. A home that stays hot overnight, outdoor work and a long public-transport journey create different practical problems. A useful plan names a workable alternative before conditions become difficult.

Know where you can cool down

Identify a reliably cooler indoor place and how to reach it. If home cooling is limited, consider an accessible public place and check its hours and transport. Do not assume every household member can travel independently or tolerate the same environment.

Plan for pets, mobility needs and the person who usually provides transport. If a power outage would remove essential cooling or medical equipment, ask the relevant service about contingency arrangements. Keep the plan simple enough to follow when you are tired or the weather is already severe.

Hydration advice may need to be individual

Regular access to fluids is part of heat preparation, but people with medical fluid restrictions or particular health conditions should follow their clinician's advice. Do not replace an individual plan with a universal internet volume target. Healthdirect on heat and hydration

Ask in advance what to do if heat, vomiting or poor intake makes the usual plan difficult. Think about where water is available during work and travel. A reusable bottle is only helpful if you can refill it and take appropriate breaks.

Learn the warning signs that change the response

Heat illness can include dizziness, headache, weakness and nausea, while confusion, collapse, seizures or severe deterioration can indicate a medical emergency. Call 000 for suspected heatstroke or serious illness. Move the person to a cooler place and begin cooling while following emergency instructions. Healthdirect's heat illness guidance

Do not force fluids on someone who is confused, unconscious or unable to swallow safely. Do not wait for a routine telehealth appointment when the person is seriously unwell. The immediate priority is emergency assistance and cooling, not obtaining a certificate or confirming a diagnosis online.

Review medicines and storage before the hot spell

Ask a pharmacist or clinician whether your medicines or health conditions require special planning in hot weather. Follow the storage instructions and ask what to do if an item has been exposed to excessive heat. Do not assume an unchanged appearance proves it remains suitable to use.

Do not stop or adjust regular treatment on your own to prepare for the weather. If you are worried about side effects, hydration or temperature sensitivity, seek individual advice. A general heatwave guide cannot safely replace the instructions for your particular care plan.

Arrange check-ins that lead to action

If someone may need support, agree on when to contact them, what to ask and what to do if they do not respond. A check-in should assess whether they can stay cool, access fluids and obtain help, not simply record that a text was sent.

Include people living alone, older relatives and anyone with mobility or communication barriers. Ask what support they want rather than assuming. Keep their usual clinical and emergency contacts available with appropriate consent.

Work and exercise may need a different plan

Consider whether strenuous activity can be moved, reduced or postponed in line with workplace and health advice. Tell the relevant person if heat is affecting your ability to work safely. The employer's heat-risk arrangements and your individual health needs both matter.

Do not treat completing a shift or event as evidence that the conditions were safe. If you develop concerning symptoms, stop and seek appropriate help. For ongoing symptoms after heat exposure, a clinician can assess whether further care is needed rather than assuming rest alone is sufficient.

Think through travel and vehicles

Plan the coolest practical travel option and allow for delays. Have a way to contact someone if transport fails. Never leave a child or dependent person in a parked vehicle; heat can become dangerous quickly. Healthdirect's hot-weather safety advice

If your route involves long waits outdoors, consider another time or arrangement where possible. A plan should include what to do when the usual option is unavailable. Do not rely on a phone battery that may run flat without having key contacts accessible another way.

Sleep and recovery matter during prolonged heat

Explain to a clinician if hot nights are causing persistent sleep disruption or worsening an existing condition. Fatigue can affect concentration and safe driving. If you are too sleepy to drive, arrange another option. Healthdirect's sleep information

Avoid using alcohol or an unreviewed sleep product as a workaround for an overheated room. Discuss the environment and health symptoms together. The practical priority may be access to a cooler place rather than a new medicine.

Keep food and essential supplies safe

Check that refrigeration and storage arrangements remain suitable, especially during a power interruption. Follow official food-safety advice rather than judging perishable food only by smell. The summer food safety guide covers planning for meals, transport and gatherings.

Keep essential supplies accessible without accumulating unnecessary products. If caring for someone else, know which items are needed for their usual plan and whom to contact if supply or storage is disrupted. A small organised kit is easier to use than a large unlabelled collection.

If symptoms continue after cooling

Seek medical advice if you remain unwell, symptoms recur or an existing condition worsens. Tell the clinician about the heat exposure, activity, fluid intake and symptoms. Do not assume the problem is fully resolved because the weather has changed.

If the symptoms are severe or worsening, use emergency care. For a non-emergency review, a doctor may still recommend examination or tests. Telehealth suitability depends on what needs to be assessed, not simply on whether you can make a call.

Review the plan after the event

Note what worked and where the gaps were: transport, cooling, contact arrangements, work breaks or access to advice. Update the plan before the next hot period. Health circumstances and household support may change between events.

The aim is not a complicated emergency manual. It is a clear set of actions that helps you stay cooler, recognise illness and obtain the right level of help when conditions become difficult.

If cooling advice conflicts with smoke conditions

Heat and smoke can occur together, making ventilation decisions more complicated. Follow current local health and emergency advice and consider moving to a suitable cooler, cleaner indoor place if home conditions cannot be managed safely.

Do not apply a generic instruction to open windows without considering the conditions outside. Equally, do not remain in an overheating home because a smoke plan assumed the building would stay cool. Ask for assistance if mobility, transport or medical needs make moving difficult.

Include this scenario in advance when your area is at risk. The bushfire smoke guide helps connect the two plans while keeping official local warnings central.

Discuss your next step with a doctor

Read about Doccio's online doctor consultation and book an online doctor appointment for a suitable non-emergency concern. Bring the relevant history, records and questions from this guide. A doctor decides whether advice, treatment, a document, testing or in-person care is appropriate. Check current fees and service information before booking. If symptoms are urgent, use the appropriate urgent or emergency service instead of waiting for a routine appointment.
