Stay safer in warm weather with practical hydration and heat-safety tips, warning signs, cooling steps and advice for higher-risk people.
Hot weather can affect anyone, especially people who work or exercise outdoors, older adults, young children, pregnant people and those with heart or other chronic conditions. Staying hydrated is important, but heat safety also means reducing exposure, taking breaks, choosing cooler times and recognising symptoms early. Personal needs vary with temperature, activity, medicines and health conditions.

Simple ways to stay safer in heat
- Carry water and drink regularly rather than waiting until you feel very thirsty.
- Use shade, cool indoor spaces or air conditioning when available.
- Plan outdoor work or exercise for cooler parts of the day and take frequent breaks.
- Wear light, breathable clothing and protect yourself from direct sun.
- Check on relatives, neighbours and friends who live alone or have health conditions.
- Ask a clinician or pharmacist how your medicines may affect heat or hydration, and never stop medicine without advice.
Know warning signs of overheating
Headache, dizziness, unusual weakness, nausea, heavy sweating, muscle cramps or shortness of breath can be warning signs that the body is struggling in heat. Move to a cooler place, rest and seek medical guidance if symptoms do not improve or are severe. Confusion, fainting, severe breathing difficulty or a suspected heat stroke situation requires urgent emergency help.
Do not rely on one hydration rule
There is no single daily water target that fits every person. Food, climate, activity, age, pregnancy and medical conditions all matter. Water is a practical choice for most everyday situations, while sugary drinks and alcohol can create additional problems in hot weather. People with kidney, heart or other conditions should ask their clinician about safe fluid amounts.
Plan before a hot day
- Check the local weather and heat-risk forecast.
- Prepare water, shade, light clothing and a way to contact help.
- Move vulnerable family members to a cool environment early.
- Avoid leaving children, older adults or pets in parked vehicles.
- Keep medicines stored according to their instructions and ask about heat-related precautions.
