El Niño: What South Africans need to know to stay safe in the heat

South Africans should take precautions against extreme heat as El Niño conditions raise concerns about hotter and drier weather across Southern Africa.

The Department of Health has urged people to protect themselves and their families from heat-related illnesses.

It was warning that heatstroke can be life-threatening.

How to stay safe in the heat

People should drink water regularly, even when they do not feel thirsty.

The department also advises limiting outdoor activities between 11am and 3pm, when temperatures can become particularly uncomfortable.

Wearing light-coloured, loose-fitting clothing can also help people stay cooler during hot weather.

Parents and caregivers should pay particular attention to young children and older people as they may need extra help staying cool and hydrated.

Pet owners should also provide their animals with plenty of drinking water, also a cool place to stay.

What are the signs of heatstroke

Extreme heat can cause serious health problems, therefore the department highlights several symptoms that people should watch for these include:

Severe headaches.

Fainting or dizziness.

Nausea or vomiting.

Dry, hot skin.

If someone shows signs of heatstroke, move them to a cool place. Cool their body with water or a wet cloth and seek medical help immediately.

Why El Niño matters

El Niño develops when parts of the central and eastern tropical Pacific Ocean become unusually warm.

The climate phenomenon can influence rainfall and temperature patterns in Southern Africa, often increasing the likelihood of hotter and drier conditions in the region.

However, its effects vary from one season and location to another.

The Department of Health is encouraging communities to share heat safety information and take precautions to protect themselves.
