The South African Weather Service (SAWS) has issued a heatwave advisory for north-western parts of the province.
Persistently high temperatures could increase the risk of heat-related illness.
According to the World Health Organisation (WHO), prolonged exposure to extreme heat can put pressure on the body, particularly when it struggles to maintain a normal temperature.
The heat can affect anyone, but older people, young children, outdoor workers and people with existing health conditions face greater risks.
Tips for keeping cool during a heatwave
Keep your home cool
Close curtains, blinds and windows during the hottest parts of the day if the air outside is warmer than inside.
Open windows in the evening or at night when outdoor temperatures drop below indoor temperatures.
Switch off electrical appliances that generate unnecessary heat and spend time in the coolest room available.
If possible, spend a few hours in a cooler public space or an air-conditioned building.
Drink water regularly
Make it a trend to drink water throughout the day, even before you feel thirsty.
If you work outdoors, make sure to carry a water bottle and take regular water breaks.
Avoid excessive alcohol as it increase the risk of dehydration.
Wear lightweight, loose-fitting clothing and a wide-brimmed hat to protect yourself from direct sunlight.
Also apply sunscreen when spending time outdoors.
Look out for children and older people
Never leave children or pets inside parked vehicles, even for a short time.
Check regularly on older relatives, neighbours and anyone who lives alone, particularly those with existing health conditions.
Keep babies and young children in cool, shaded places.
Know the signs of heat illness
Extreme heat can cause heat exhaustion or heatstroke.
Watch for symptoms such as dizziness, headaches, nausea, weakness and heavy sweating.
One should follow the latest SAWS advisories and take extra precautions while high temperatures persist.
