What examples are there of hypo-tonic drinks?

There aren't any drinks that are technically considered "hypotonic". The term "hypotonic" refers to a solution with a lower concentration of solutes (like minerals and sugars) compared to another solution, like the fluids in your body.

Here's why we don't talk about hypotonic drinks:

* Our bodies are already hypotonic: The fluid inside our cells (intracellular fluid) is hypotonic compared to the fluid outside our cells (extracellular fluid). This is necessary for cells to function properly.

* Hydration is the goal: When we talk about sports drinks or electrolyte drinks, we're primarily focused on hydration and electrolyte replenishment.

* Terminology: While the terms "hypotonic" and "isotonic" are sometimes used for sports drinks, they are not standardized or precise terms in this context.

Here's what we *do* talk about:

* Isotonic drinks: These drinks have a similar concentration of solutes to the fluids in our body, making them ideal for hydration during exercise. Examples include:

* Many commercially available sports drinks

* Coconut water

* Hypotonic drinks are sometimes called *low-concentration* drinks: These drinks contain fewer solutes than isotonic drinks and are absorbed more quickly by the body. They can be beneficial for rehydration after intense exercise or when you need to hydrate quickly. Examples include:

* Water

* Some low-sodium sports drinks

Important note: It's important to choose a drink that fits your needs and the intensity of your activity. Consult with a healthcare professional or registered dietitian if you have questions about hydration or electrolytes.
