This recent spell of hot weather in the UK has been challenging for many of us. While moderate sun exposure can be hugely beneficial for our health, supporting immune system function and physiology… prolonged heat does unfortunately place extra demand on our bodies. Especially for those living with cancer, recovering from treatment, or managing ongoing fatigue. Our digestion can be disrupted and even simple daily activities can feel more draining when temperatures climb.
One of the most common messages is to drink more water. That’s certainly important, but hydration during a heatwave isn’t just about how much water you drink… it’s about your body’s ability to absorb and use that water effectively.
That’s where electrolytes come in.
What are electrolytes?
Electrolytes are essential minerals that carry an electrical charge, help regulate many of the body’s most important functions and limit dehydration. They include sodium, potassium, magnesium and calcium.
These minerals help to:
- Maintain fluid balance
- Support healthy muscle function
- Regulate nerve signalling
- Keep the heart beating normally
- Help transport nutrients into cells
Every time we sweat, we lose not only water but also these valuable minerals.
Replacing fluid without replacing electrolytes can sometimes leave you feeling as though you’re still dehydrated, even if you’ve been drinking plenty.
Signs you may need more than water
Everyone’s body is different, but some common signs that electrolyte levels are running low include:
- Feeling unusually fatigued
- Muscle cramps
- Headaches
- Dizziness
- Weakness
- Feeling thirsty despite drinking water
These symptoms can also have many other causes, particularly during cancer treatment, so it’s always important to discuss persistent or severe symptoms with your medical team.
8 natural ways to support electrolyte balance
Electrolytes to support hydration during a heatwave can be found in a varied, nutritious diet alongside adequate fluid intake.
Here are 8 naturally electrolyte-rich foods to include where appropriate:
Heatwaves can make everyday life feel that little bit harder, but introducing electrolyte-rich foods and fluids throughout the day can lessen the physical impact and better support you during extreme temperatures.
At Together Against Cancer, we often welcome guest speakers to the Wellness Centre to support your healing journey, sharing informed guidance on nutrition, hydration and other lifestyle approaches that support you better during a cancer journey.
