  • stock up on food, water and medicines, and put ice blocks and packs in the freezer
  • store medicines safely at the recommended temperature

There are ways to keep cool when the temperature rises:

  • stay inside and keep out of the heat as much as possible
  • if you go outside, wear light clothes, a hat and sunscreen, and take water 
  • plan shopping, appointments, exercise and gardening for early in the day, or ask someone to help
  • keep your home cool by drawing the blinds, turning on fans or air-conditioners and opening doors and windows at night
  • take cool showers, splash yourself with cold water, or use a cool damp cloth to cool off
  • keep an eye on your mood and ability to think and plan. Seek support if you’re worried
  • cool off at an air-conditioned shopping mall, community centre, library or your local swimming pool
  • drink plenty of water, even if you don’t feel thirsty. Avoid alcohol, tea, coffee and sugary drinks
  • eat small meals and cold foods like salads and fruit.

Babies and children are especially at risk from dehydration. Keep them safe by encouraging children to drink plenty of water. Watch for dark urine and check the frequency of nappy changes.

Ensure pets are well hydrated and have plenty of shady spots outside.
