The Heat Can Affect More Than Your Comfort

A warm afternoon might seem like the perfect excuse to sit outside with a cup of tea. But when temperatures climb, heat can affect more than your comfort, particularly if you are older or managing a long-term health condition.

New Zealand is not known for the extreme summers experienced in some countries, yet heat can still cause illness. Health New Zealand warns that older adults are more vulnerable to heat-related problems, especially people with existing health conditions or those taking certain medicines.

One complication is that you may not recognise dehydration straight away. As we age, thirst can become a less reliable signal that the body needs fluids. Some medicines, including diuretics used for certain heart conditions or high blood pressure, can also increase fluid loss.

If you have heart or kidney disease and have been advised to limit fluids, ask your healthcare provider how to manage hydration during hot weather rather than simply drinking more.

Your home can become uncomfortable even when you stay indoors. Close curtains or blinds on sunny windows during the hottest part of the day, use a fan or air conditioning if available, and open windows when the outdoor air becomes cooler. If your home remains stifling, consider spending part of the day somewhere cooler, such as a library or shopping centre.

It also helps to rethink the timing of everyday activities. Move gardening, errands, and walks to the cooler morning or evening hours. Choose lighter clothing, keep water nearby, and eat refreshing foods such as fruit. If you live alone, arrange a quick phone call with a friend or relative during particularly hot spells.

Watch for unusual weakness, dizziness, headaches, intense thirst, or nausea. If you feel unwell from the heat, move somewhere cool and drink cool fluids if you can. Seek medical advice if symptoms persist or worsen. Confusion, fainting, or reduced consciousness can indicate a serious problem requiring urgent help.

Staying safe in hot weather does not mean cancelling everything you enjoy. It means recognising when conditions call for a change of plan, and taking a few sensible precautions before the heat catches up with you.
