Hydration tips summer are often about what to drink, but a recent study shows that women’s hydration and sodium needs change significantly in hot weather — and that could matter more than you think, even now in mid-autumn. As the clocks go back and the days get shorter, it’s easy to forget that the body still needs to manage heat, especially if you’re heading into the summer months ahead. The Gatorade study highlights how women, in particular, may need more sodium than they usually get from water alone, especially when the weather gets warmer. This is not just about sports performance — it’s about how the body responds to heat, and how that can affect everyday energy and comfort.
What the research says
A 2026 scoping review looked at the effects of dietary changes and allicin on electrolytes in beef bulls, showing how the balance of nutrients and electrolytes can influence overall health and function. While this study was on animals, it gives a clear picture of how electrolytes — like sodium, potassium, and magnesium — work together in the body. These are the same electrolytes that help regulate fluid balance, muscle function, and nerve signals in humans.
The study also highlights the importance of maintaining a consistent intake of these minerals, especially when the body is exposed to heat. In hot conditions, the body loses more fluids and electrolytes through sweat, and if these are not replenished, it can lead to imbalances that affect how the body functions. This is particularly relevant for women, who may experience different patterns of fluid loss and electrolyte depletion compared to men, depending on factors like activity level, diet, and hormonal changes.
Understanding how these electrolytes interact can help in making more informed choices about what to drink or eat, especially when the body is working harder to manage heat. The research also suggests that the way electrolytes are consumed — whether through food, drinks, or supplements — can influence how effectively the body retains and uses them.
Electrolytes and the body’s response to heat
Why sodium matters in hydration
Sodium is a key electrolyte in the body, and it plays a big role in keeping fluids balanced. When you sweat, you lose sodium, and if you don’t replace it, your body can struggle to retain water. This is why, even in the UK, where summer heat can be intense, people may feel more dehydrated than they expect. The study suggests that women, in particular, may need more sodium — and that could mean a simple change in what you drink, or even what you eat, could make a difference.
What to look for
When choosing a drink or supplement to help with hydration, it’s not just about water — it’s about what else is in it. Look for drinks that contain sodium, potassium, and magnesium, as these are the main electrolytes the body loses through sweat. Some sports drinks are high in sugar, which can be a problem if you’re trying to stay balanced. If you’re looking for something more natural, you might want to look for electrolyte powders or drinks that are low in sugar and high in minerals.
When selecting a supplement or drink, it’s also helpful to consider the source of the electrolytes. Some products use refined minerals, while others use naturally occurring sources, such as sea salt or mineral-rich water. This can affect how the body absorbs and uses the electrolytes. If you’re looking for a more tailored option, you might want to choose a product that allows you to adjust the amount of each electrolyte based on your needs.
Common questions
Can I get enough sodium from food?
Yes, but it depends on what you eat. Foods like bread, cheese, and processed meats are high in sodium. If you’re eating a balanced diet, you may get enough sodium naturally. However, if you’re sweating a lot — especially in the summer — you may need to add a little extra sodium to your drinks or meals.
Do I need to take electrolyte supplements every day?
Not necessarily. If you’re not doing a lot of physical activity or spending long hours in the heat, you may not need to take them every day. However, if you’re feeling tired, dizzy, or experiencing cramps, it could be a sign that your body is losing more electrolytes than it’s getting back.
What’s the best way to stay hydrated in the UK summer?
It depends on your lifestyle. If you’re going out a lot, a drink with electrolytes can help you stay balanced. If you’re more of a homebody, you might find that a simple glass of water with a pinch of salt or a few drops of lemon can help your body manage heat more easily. You might also want to look at our electrolyte powder, which is a natural option for adding minerals to your water.
What to look for in a natural supplement
If you’re looking for a supplement to help with hydration, it’s important to read the label. Look for products that contain sodium, potassium, and magnesium — these are the main electrolytes the body loses through sweat. Some supplements also include other minerals like calcium and zinc, which can support overall health. If you’re looking for something that’s easy to take, a powder or a tablet can be a good option. If you’re more of a drinker, you might prefer a drink that’s low in sugar and high in minerals.
How to read a label
When looking at a supplement or a drink, it’s important to know what you’re getting. Look for the amount of sodium, potassium, and magnesium in the product. Some labels may list these as “electrolytes,” but it’s better to check the specific amounts. If you’re looking for a natural option, you might want to avoid products that are high in sugar or artificial ingredients. A simple label with the names of the minerals and the amounts can help you choose the right product for your needs.
Also, pay attention to the source of the ingredients. Some products use isolated minerals, while others use whole food sources, which can affect how the body absorbs and uses them. If you’re looking for something that’s easy to take and doesn’t contain unnecessary additives, you might want to choose a product that lists only the minerals you need, without extra fillers or preservatives.
What to do if you’re not sure
If you’re not sure what to take, or if you’re not sure how much you need, it’s a good idea to start with a small amount and see how your body responds. You might find that a little extra sodium or magnesium can make a big difference in how you feel, especially if you’re spending time in the heat. If you’re taking medication or are pregnant, it’s a good idea to speak to your GP or pharmacist before starting any new supplement.
