sparkling water is in a boom with the likes of sodastream, bubly, perrier, and la croix. but is the bubbling stuff really good for you? sparkling water is one of the best alternatives for people looking to cut back on pop or alcohol, as it can “scratch the itch” of wanting something bubbly to sip on at night. brands like liquid death have even gone for a more hardcore look that may be mistaken at a glance for alcohol, while encouraging drinkers to “murder their thirst.”
some say that sparkling water makes you feel full longer, thanks to the bubbles, while others suggest it may help with constipation. but is the fancier version of the simplest beverage in the world really all that different from the still version? 

where carbonated water come from?

the carbonation process, which is used to make sparkling water, was invented in 1767 by joseph priestley. however, the use of carbonating beverages wasn’t commercialized until about 20 years later when jacob schweppe — founder of the soft drinks manufacturer schweppes — founded his company. 
sparkling water is made from dissolving carbon in water using high gas pressure and low temperatures. this creates carbonic acid, which gives the water its effervescence, according to water company borg & overstrom.

however, there are places in the world where sparkling water happens to occur naturally.
soda springs, idaho has a geyser in the middle of the town that sprays sparkling water into the air. the water in the geyser occurs naturally underground thanks to a pocket of co2 gas, but the actual geyser itself was accidentally man made and goes off every hour, on the hour. the town also has carbonated springs that people can bathe in.

sparking water may also be good for more than just quenching your thirst. according to a 2011 study published by the national center for biotechnology information, sparkling water can ease constipation in stroke survivors who are subsequently unable to get out of bed. (a concern in many elderly communities.)
in the study, patients in the control group drank still water, while those in an experimental group drank sparkling water for two weeks. symptoms of constipation significantly decreased in the group that drank the carbonated water.

can bubbly water be bad for your teeth?

sparkling water may make you feel bloated, just as any other carbonated beverage would. this could also lead to belching, gas, and stomach pain. 
carbonated water is slightly more acidic than flat water, however, according to the
american dental association, regular sparkling water is generally safe for teeth. depending on the brand of sparkling water, there could be minerals that could be harmful to teeth, but this is usually down to sugars and acids that could be added. the ada does mention citrus flavoured water specifically as having higher volumes of acid, which could lead to increased risk of damaging tooth enamel. 
there is also the cost factor to consider. sparkling water generally costs more than the still counterpart — unless you’re drinking fiji or something similar.
