In Christchurch last week a woman with multiple sclerosis died after overheating, as that city hit 32C on Wednesday. People with multiple sclerosis can struggle to control their body temperature in hot weather, as can the very young, the very old and the simply unwary.
It is important to be aware of the threat posed by the heat. Heatstroke, dehydration and heat exhaustion can be fatal and can be prevented.
Health experts advise plenty of water, ice packs and fans as well as staying out of the sun and not leaving children, older people or pets in parked cars.
Police are also urging that people need to be vigilant and use their common sense, after police in the Waikato attended an emergency rescue yesterday where two pre-schoolers had been left locked in an overheated car.
Let's all stay safe in the heat, be sensible and keep an eye out for others.
