Exercisers who prefer fizz
After a gym session, fitness class or short run, plain sparkling water is an option for replacing fluid if its taste makes water more appealing. The NHS suggests sparkling water for people who do not like plain water.
Who is sparkling water for after exercise?
The useful distinction is between replacing fluid after a routine session and planning for substantial sweat loss.
People exercising for longer or sweating heavily
A sparkling drink can still provide fluid, but it should not be mistaken for a sodium-replacement plan. UK sports-hydration guidance advises including sodium when exercise lasts over two hours or sweat losses are high.
Shoppers considering flavoured water
If you want fizz without choosing a regular sweet fizzy drink, read the ingredients and sugars information for the particular flavour. A flavoured product need not have the same composition as plain sparkling water.
What should you check before choosing?
Start with the demands of the workout, then check the drink’s composition and the pack you will use.
| Priority | What to check | Your needs |
|---|---|---|
| Fluid after a routine workout | Choose plain sparkling water if you want water with fizz. Check whether the bottle size is convenient where you finish exercising. | I would rather drink fizzy water than still water after a class or short run. |
| Long sessions or heavy sweating | Consider exercise duration, heat and sweat loss. UK sports-hydration guidance advises including sodium for exercise over two hours or high sweat losses; plain sparkling water is not a formulated electrolyte drink. | After a long or especially sweaty session, I need to plan for salts as well as fluid. |
| Flavour and ingredients | For flavoured varieties, read the ingredient list for sugars, juice, acids and sweeteners. Compare sugars per 100ml on the nutrition panel. | Fizzy flavour appeals to me, but I want to know what is in this particular drink. |
| Frequent fizzy drinking | Consider how often you sip carbonated drinks. The NHS associates their acidity with dental erosion, including when they contain no sugar. | If I keep a drink beside me throughout the day, I may prefer still water for some of that time. |
| Pack size and storage | Compare individual 500ml bottles with larger bottles or multipacks according to where you will drink them. Follow the chosen product’s directions after opening. | A small bottle fits my gym bag; a larger one may suit drinking at home. |
What is easy to overlook?

Treating sparkling water as a complete recovery drink
Plain sparkling water replaces fluid, but it is not formulated to provide sodium or recovery nutrition. This distinction matters particularly after prolonged exercise or heavy sweat loss.
For those sessions, plan how to replace both fluid and salts. UK sports-hydration guidance advises including sodium when exercise lasts over two hours or sweat losses are high.

Assuming zero sugar removes the dental trade-off
The NHS associates carbonated drinks with dental erosion because of their acidity, regardless of sugar or sweetener content.
If you sip fizzy drinks frequently or have dental concerns, consider still water as an everyday alternative.

Choosing a flavoured variety by its front label alone
Flavoured sparkling drinks can contain sugars, juice, acids or sweeteners that are not ingredients of plain water.
Read the ingredient list and sugars per 100ml. People with phenylketonuria need to avoid products containing aspartame, also labelled E951.

Common questions
Can I drink sparkling water after a workout?
Yes, plain sparkling water can replace fluid after an ordinary workout if you enjoy it. The NHS recommends water for replacing fluid lost through physical activity and suggests sparkling water for people who dislike plain water. A drink of plain water does not, by itself, provide recovery nutrition or a plan for substantial sweat-sodium loss.
When should I consider sodium as well as water?
Consider sodium replacement when exercise lasts over two hours or sweat losses are high, according to the cited UK sports-hydration guidance. Hot conditions also affect the choice: the British Heart Foundation advises considering drinks with electrolytes when exercising in heat. Do not assume a specialist drink is needed solely because you have exercised.
Is sugar-free sparkling water the same as still water for teeth?
No. The NHS associates carbonated drinks with dental erosion due to acidity even when they contain no sugar. If you sip fizzy drinks frequently or have dental concerns, consider still water for some of your everyday drinking.
What should I read on a flavoured sparkling-water label?
Check the ingredients for sugars, juice, acids and sweeteners, then compare sugars per 100ml on the nutrition panel. Do not assume a flavoured variety has the same composition as plain sparkling water; people with phenylketonuria also need to check for aspartame or E951.
How should I store a large bottle after opening it?
Follow the storage directions on that bottle, including any instruction to refrigerate it and use it within a stated period. Check the particular product rather than assuming the same directions apply to every brand or bottle size.
