HEATWAVE ACTION GUIDE

HEATWAVES CAN KILL

Heatwaves are perhaps our most under-rated natural hazard. In Australia during the 20th century, heatwaves caused more deaths than any other natural hazard. In 1939 alone, a heatwave in southern Australia caused 438 deaths and seriously affected many thousands. Heatwaves also cause expensive livestock/crop losses and damage to roads, electrical equipment, railways, bridges etc.

HEAT STRESS AND THOSE MOST AT RISK

Every summer people suffer from heat stress when the body absorbs more heat than it can dispel. Prompt action will avoid the potentially fatal effects of fully-developed heat stroke. At most risk are young children; the elderly; people with alcohol, weight, or health problems; or those on medication/drugs with a dehydrating effect. Seek medical advice in such cases.

AVOIDING HEAT STRESS

• Wear lightweight, light-coloured, loose, porous natural fibre clothes. Avoid strenuous activities.
• Drink 2 to 3 litres of water per day, even if not thirsty.
• Avoid alcoholic, caffeinated or carbonated (soft) drinks.
• Don't take salt tablets unless prescribed by a doctor.
• Avoid heavy protein foods (eg meat, dairy products) which increase body heat and fluid loss.
• Keep your home cool with curtains, shutters, or awnings on the sunny sides and open windows at night.
• If you don't have air conditioning, use fans, damp clothing and have frequent cool showers.
• Spend as much time as possible in air conditioned buildings (eg shopping centres, galleries, museums).
• Avoid direct sunlight. Wear a hat and sunscreen as sunburn limits your ability to cope with heat.
• If you work outside, keep hat and clothing damp.
• Don't leave children or pets in parked vehicles.
• If you suffer chronic illness or feel ill, see a doctor.
• Keep animals in the shade with plenty of water.
