Keep cool amid the summer heat

NSW Health is urging people to follow a number of simple precautions to keep cool and stay safe as the state grapples with high temperatures.

With predicted temperatures in the high 30s and early 40s, NSW Health Public Health Physician, Dr Jeremy McAnulty said people of all ages should take care and avoid heat exhaustion by protecting themselves against the sun and heat.

“People need to be alert for the symptoms associated with heat exhaustion in themselves or others, especially young children and the elderly,” Dr McAnulty said.

“Symptoms of heat exhaustion include nausea, faintness, dizziness, loss of appetite, weakness, headache, and vomiting.

“If any of these symptoms occur, lay the person down and apply cool, wet towels around the neck and under the arms, and have them drink cool fluids.

“If the person does not respond to treatment or has severe symptoms such as confusion or collapse, call 000 immediately and ask for the Ambulance Service.

“People with existing diseases or sicknesses such as heart problems, diabetes or hypertension should take extra caution in this heat.

“If you have friends or neighbours who are elderly or unwell check on them regularly to ensure they are okay.”

Dr McAnulty said other people who may be at risk of heat exhaustion include outdoor workers, people in workplaces with inadequate cooling systems and workers involved in strenuous physical activities.

The high temperatures are often associated with increased air pollution levels. People with asthma are most susceptible to the effects of the high air pollution. Asthma sufferers are also advised to stay indoors and to avoid outdoor exercise, particularly in the late afternoon.

Dr McAnulty said people should follow these heat safety tips:

• Consume plenty of water, preferably every 15-20 minutes, to stay well hydrated
• Avoid drinking alcohol, sugary or caffeine drinks which can increase dehydration.
• Feed breastfed infants more frequently to help keep up their fluids.
• Keeping as cool as possible by wearing light, loose, comfortable clothing.
• Keeping out of the sun in the hottest part of the day – between 11am and 3pm – preferably in an air-conditioned environment.
• Avoid outdoor exercise or strenuous physical activity, especially in the middle of the day.
• Avoid hot winds.
• Take advantage of the shade when outside; it is a great defence against the sun.
• Don’t forget to cover up when in the sun, wear a shirt, sunscreen and hat.
• Replenish salt lost from sweating by eating proper, regular meals.

“Keep in mind that heat generated in a closed car can be fatal to children,” said Dr McAnulty.

“Never leave children or animals in the car unattended.

“If you are expecting to take a long trip by car, do pack plenty of healthy snacks and water to drink during the journey. This will help sustain children and adults energy levels.

“Keep a special eye on infants as less frequent wet nappies, irritability or sleepiness can be signs of dehydration in babies. If you are concerned that your baby is experiencing these symptoms please seek medical attention early.” <br>

With high fire dangers across the state, Dr McAnulty also encourages forward planning to stay away from hazardous areas. <br>
