Carolina Goncalves, superintendent pharmacist at Pharmica, agrees: “Cool or room-temperature beverages tend to be absorbed more quickly than very hot or cold drinks because extreme temperatures can slow down gastric emptying.

“When water is at a moderate temperature, it passes through the stomach more rapidly, allowing for quicker absorption in the intestines. This efficient absorption helps speed up the hydration process, ensuring fluids reach cells and tissues faster.”

2. Add electrolytes to your water

Water alone cannot keep you hydrated – electrolytes, such as sodium, potassium and magnesium, are key for directing water and nutrients to the areas of the body that need it the most and ensuring the balance of water within your cells.

You can get these electrolytes in your diet but adding them directly into your water is a quick and easy way to ensure you’re getting enough.

You can get these electrolytes in pre-made packets or, if you prefer to keep things natural, have some coconut water (which contains electrolytes such as potassium, sodium and manganese) with a pinch of salt. Some people claim Himalayan pink salt works best due to its slightly higher nutrient content, but this hasn’t been proven, so it’s a preference.

3. Don’t forget carbohydrates

There’s a reason why many sports drinks contain glucose: as well as providing essential fuel to the muscles, carbohydrates help in the hydration process too.
