As South Africa’s summers become hotter, longer and more intense, staying hydrated has shifted from an athletic concern to an everyday health essential. With earlier heat waves and higher average temperatures reported in recent years, more South Africans are spending time in conditions that increase the risk of fluid and mineral loss through sweating.
Hydration is no longer only relevant to marathon runners and gym enthusiasts. It matters for anyone spending time outdoors, commuting, working in warm environments, travelling, entertaining, or attending festivals and events.
According to REVIVE, a locally developed electrolyte brand formulated with science-backed mineral ratios, the key to better hydration isn’t just drinking more water — it’s hydrating smarter.
“Dehydration doesn’t only happen on a sports field,” says Mark Myerson, CEO of REVIVE. “It’s common at the beach, on long road trips, at festivals, at a braai, or even during a normal workday in extreme heat.”
“What most people don’t realise is that when electrolytes drop, your energy, mood and focus often drop with them. Hydration is chemistry. The body absorbs and retains water far more effectively when electrolytes are present.”
Why electrolytes matter more than water alone
Electrolytes like sodium, potassium and magnesium are essential for fluid balance, muscle function, nerve signalling and temperature regulation. Sweating leads to the loss of both water and minerals, which is why water alone is often not enough to fully restore balance.
Everyday summer scenarios where electrolytes can help include:
long beach or pool days
hiking and outdoor exercise
gardening or home DIY projects
festivals, markets and outdoor events
road trips
attending or hosting a braai
working in hot, poorly ventilated spaces
Rethinking sodium’s role in hydration
Salt has traditionally been viewed as something to limit, but newer research highlights a more nuanced story. Sodium is essential for cellular function, fluid balance and effective hydration. Without adequate sodium intake, the body struggles to retain water and maintain proper electrolyte balance.
“In the context of hydration, sodium plays a fundamental role,” says Myerson. “Without enough sodium, the body simply cannot absorb water effectively.”
How to stay “summer strong”
REVIVE recommends the following simple strategies to support hydration in the heat:
Start early: Hydrate before exposure to heat, not only when you feel thirsty.
Balance water with electrolytes: Too much plain water can dilute essential minerals.
Eat hydrating foods: Include water-rich fruit and vegetables and mineral-rich meals.
Take shade breaks: Cooling down periodically supports temperature regulation.
Alternate drinks when socialising: Swap every alcoholic drink for electrolytes or a hydration mix.
Know dehydration signals: Headaches, irritability, dizziness, nausea, cramps and fatigue suggest your body needs fluids plus minerals, not water alone.
This summer, REVIVE encourages South Africans to choose hydration that supports both daily wellbeing and performance — helping you stay balanced, energised and summer strong.
