Can Sparkling Water Cause Headaches?
Sparkling water, or soda water, has become increasingly popular as more people move away from sugary soft drinks. However, some people report getting headaches after drinking carbonated beverages. So what's behind this fizzy phenomenon?
What is Soda Water?
Soda water, also known as carbonated water or seltzer, is simply water containing dissolved carbon dioxide gas. It gives water its bubbly, effervescent quality.
Unlike soft drinks, sparkling waters do not contain added sugars or artificial ingredients. However, they are acidic due to the carbonation process.
Why Sparkling Water May Cause Headaches
There are a few theories as to why some people may develop headaches after drinking soda water:
Gas Buildup
Fizzy bubbles release carbon dioxide gas into the digestive system. For some, excess gas from the sparkling water may accumulate and dilate blood vessels or nerves surrounding the brain, causing head pain.
Dehydration
Although soda water is mostly water, evidence suggests carbonated beverages may reduce hydration more than still water. Dehydration and electrolyte disturbances can be headache triggers.
Acidity
Carbonic acid gives soda water an acidic pH around 3-4. Increased acidity may provoke headaches in those predisposed, especially migraine sufferers.
Trigeminal Nerve Irritation
Bubbles may irritate the trigeminal nerve in the face and mouth, which communicates with brain pathways involved in headaches.
Ingredient Sensitivity
Though plain soda water contains no additives, flavored seltzers feature ingredients like citric acid, sodium benzoate or potassium sorbate preservatives which some people could react to.
Who Might Be Impacted?
While most people can enjoy an occasional sparkling water without issue, it may provoke headaches in susceptible individuals.
Those with Chronic Headaches
People with migraine, tension headache or headache prone conditions may be more vulnerable to potential headache triggers in soda water.
Sensitive Stomachs
Those with digestive issues like IBS or inflammatory conditions may experience symptoms like gas, bloating or diarrhea from overconsumption of carbonated drinks, potentially along with headache.
Low Blood Sugar
If soda water diminishes hydration, it could also worsen low blood sugar headaches in diabetics or others susceptible to drops in blood glucose.
Anxiety and Stress
Stomach disturbances from soda water could heighten stress or anxiety, also known headache triggers. Environmental triggers like noise or lighting in loud bars serving sparkling drinks may contribute too.
Tips to Prevent Soda Water Headaches
If you enjoy bubbly water but get headaches, try these simple strategies:
Moderate Intake
Limit soda water to 1-2 glasses a day and avoid going overboard. Spread consumption throughout the day instead of drinking a lot at once.
Alternate with Still Water
Rotate plain water into your routine to stay hydrated. For every glass of sparkling water, have a glass of regular water.
Sip Slowly
Gulp carbonated drinks slowly and deliberately instead of drinking rapidly, which introduces more gas into your digestive tract quicker.
Avoid Triggers
Skip flavored sodas with suspicious ingredients. Also be cautious drinking sparkling water in noisy, bright environments containing possible headache triggers if sensitive.
Eat Beforehand
Consume sparkling water with a snack or meal to prevent low blood sugar and electrolyte disturbances.
Try Decreasing Carbonation
Some soda makers allow adjusting carbonation levels. Try lower bubble settings if standard carbonation bothers you.
When to See a Doctor
Occasional mild headaches from sparkling water are usually harmless. But recurrent or worsening headaches after drinking soda water merit medical evaluation, especially if you experience:
- Severe head pain
- Nausea or vomiting
- Vision changes
- Confusion
- Sensory disturbances
- Weakness
See your doctor to rule out serious causes like migraine, medication side effects or underlying illness. Keeping a symptom journal tracking suspected sparkling water headache triggers can help.
Preventative Medications
If soda water reliably causes your headaches, ask your doctor about preventative medications you can take before drinking carbonated beverages.
Alternative Drinks
Determine if switching to still water, fruit-infused water or non-carbonated beverages prevents your headaches. Work with your doctor to identify the specific culprit.
The Bottom Line
Sparkling water is generally safe but its bubbles, acidity and dehydrating quality may provoke headaches in prone people. Modifying how you drink soda water or avoiding overconsumption can help, but recurrent headaches may signal an underlying issue warranting medical advice.
Pay attention to your body's signals and how you feel drinking bubbly beverages. Finding your personal tolerance level is key to still enjoying soda water safely without uncomfortable headaches.
