Perth heat can arrive quickly, especially when a warm night follows a hot day. Staying well is not about proving that you can “handle” heat. It is about adjusting plans, reducing exposure and recognising when symptoms need urgent care. This page is general information, not a personal heat-risk assessment.
Plan around heat
Check the forecast and shift demanding tasks away from the hottest part of the day.
Use simple cooling steps
Shade, airflow, light clothing, water and rest can all reduce exposure.
Act on red flags
Confusion, collapse, seizure or loss of consciousness need emergency help.
Heat safety starts before you leave home
Look at the forecast for the full day and night, not just the current temperature. Heat can be harder to manage when sleep has been poor, indoor spaces stay warm overnight, the air is still, or outdoor work and travel cannot easily be shortened. Choose cooler times for exercise, errands and physical tasks where possible, and have a shaded or air-conditioned place you can use if conditions change.
Heat does not affect everyone in the same way. Babies and young children, older adults, people with long-term health conditions, people who work outdoors and people who are new to a hot climate may need a more cautious plan. If you have been given individual advice about fluids, activity or regular treatment, follow that advice rather than a generic article.
What a practical heat plan can look like
Wear loose, light-coloured clothing suitable for the activity, use sun protection, carry water and take regular shade breaks. On very hot days, consider whether the task can wait, be done indoors or be divided into shorter sessions. Keep vehicles and homes as cool as safely possible, and check on people who may not be able to cool themselves or ask for help easily.
For travel, plan the route, shade and water stops before setting out. Never leave children, older adults or animals in a parked vehicle. If you are exercising, working or attending an outdoor event, tell someone your plan and leave yourself a simple option to stop early.
Know the difference between discomfort and danger
Feeling thirsty, tired or sweaty can be an early sign that it is time to cool down, rest and review the plan. Symptoms such as headache, dizziness, nausea or cramps can have many causes, including heat, and should not be self-diagnosed from an image or checklist. If symptoms are not improving, are severe or are unusual for you, get medical advice.
A person with serious heat illness may become confused, poorly coordinated, faint, behave unusually, have a seizure or lose consciousness. These signs should never be managed by simply waiting it out, with a supplement, or with a routine clinic appointment.
Where can Chinese medicine fit?
A Chinese medicine consultation can be a place to discuss sleep, routine, stress, mobility and how to make everyday activity feel manageable in warmer weather. It should not be described as a way to prevent heatstroke, make a heat emergency safe or replace urgent medical assessment. Tell your practitioner about your diagnoses and all current treatment so that care can be coordinated appropriately.
When to call for emergency help
Call triple zero (000) for an ambulance if a person exposed to heat is confused, collapses, has a seizure, loses consciousness, has severe shortness of breath or chest pain, or is not responding normally. While waiting, move them to a cooler shaded place if it is safe and follow emergency instructions. Seek prompt medical advice for symptoms that are severe, worsening or not settling after cooling and rest.
Questions to ask before a hot day
- When will the heat be greatest, and can the plan be moved to a cooler time?
- Where are the shaded, cool or air-conditioned stops on my route?
- Do I have water, suitable clothing and a way to contact someone if I need to change plans?
- Does anyone in my group have health, age, mobility or work factors that need a more cautious plan?
- What symptoms would mean it is time to stop and seek medical help?
