Scorcher Alert: How to Beat the Heat and Protect Your Health in New Zealand
Heatwaves aren't just uncomfortable; they can be life-threatening. Our bodies naturally regulate temperature, but during extreme heat, this system can struggle. This can lead to heat exhaustion, characterised by symptoms like dizziness, headache, nausea, and rapid heartbeat. If left untreated, heat exhaustion can progress to heatstroke, a medical emergency requiring immediate attention. Heatstroke can cause confusion, seizures, and even organ failure.
While everyone is susceptible to heat-related illnesses, certain groups are more vulnerable:
- Young Children: Their bodies don't regulate temperature as efficiently as adults.
- Elderly: They may have underlying health conditions and be less able to sense or respond to heat.
- People with Chronic Illnesses: Conditions like heart disease, diabetes, and respiratory problems can exacerbate the effects of heat.
- Outdoor Workers: Those working in the sun for extended periods are at increased risk.
- People Taking Certain Medications: Some medications can interfere with the body's ability to regulate temperature.
Here's how to keep yourself and your loved ones safe during this heatwave:
- Stay Hydrated: Drink plenty of water throughout the day, even if you don't feel thirsty. Avoid sugary drinks and excessive caffeine.
- Seek Shade: Spend time in shaded areas, especially during the hottest part of the day (typically between 11 am and 4 pm).
- Cool Down: Take cool showers or baths. Use fans and air conditioning if available.
- Wear Appropriate Clothing: Opt for loose-fitting, light-coloured clothing.
- Check on Vulnerable People: Regularly check on elderly neighbours, relatives, and friends who may be at risk.
- Never Leave Children or Pets in Cars: Temperatures inside a parked car can rise rapidly, even on a mild day.
- Limit Strenuous Activity: Avoid intense exercise during the hottest part of the day.
Knowing the signs of heat exhaustion and heatstroke is crucial. If you or someone you know experiences any of the following symptoms, seek medical attention immediately:
- Heat Exhaustion: Heavy sweating, weakness, dizziness, headache, nausea, vomiting, muscle cramps.
- Heatstroke: High body temperature (above 40°C), confusion, seizures, loss of consciousness.
Keep an eye on weather forecasts and heed any warnings issued by the MetService. Your local council may also have cooling centres or other resources available. By taking these precautions, you can enjoy the summer sun safely and avoid the serious health risks associated with extreme heat. Noho haumaru! (Stay safe!)
