Scientists Are Finding Health Benefits of Carbonated Water

Have you ever sipped on a glass of carbonated water and immediately felt a wave of refreshment unlike any other?

There’s a fascinating science behind why carbonated water, often seen as just a bubbly alternative to flat water, might be more beneficial than we realize.

Carbonation is More Than Just Bubbles

Carbonation is the process of dissolving carbon dioxide (CO2) gas in water, creating that familiar fizz and slight tanginess we associate with drinks like soda, club soda, and seltzer water.

But it’s not just about the sensory experience.

When CO2 mixes with water, it forms a weak acid called carbonic acid, slightly lowering the pH of the water. This might sound concerning, but this very reaction unlocks a cascade of potential health benefits, starting with improved hydration and digestion. ^(ref)

The Bohr Effect

One of the most intriguing aspects of carbonated water is its relationship with our body’s oxygen absorption process, known as the Bohr effect.^(ref) Contrary to what we might assume, having more CO2 in our system can enhance oxygen delivery to our cells.

This is because CO2 helps to lower the pH of our blood slightly, making it easier for oxygen to be released from hemoglobin and absorbed by the body. This delicate balance is crucial, especially during stress or panic attacks, where the right amount of CO2 can mean the difference between shallow, panicked breaths and calm, deep breathing.

Carbonated Water & Circulation

In Europe, the therapeutic use of carbonated water has taken a fascinating turn with the introduction of carbonated spas. These spas utilize CO2-infused water to treat various circulatory issues, particularly peripheral vascular disorders.

The science suggests that CO2 can significantly improve microvascular circulation, even aiding in treating diabetic wounds and potentially reducing the need for amputations ^(ref). It’s a testament to the power of CO2 in enhancing blood flow and oxygen delivery to where it’s needed most.

A Potential Ally Against the C-Word?

While the research is still in its early stages, there’s compelling evidence to suggest that CO2 might play a role in cancer prevention and treatment. Studies have shown that CO2 can inhibit cancer metastasis, induce apoptosis (the process of programmed cell death in cancer cells), and even affect certain genes involved in the transition from a normal cell to a cancerous one.^(ref) 

This is particularly fascinating when considering the relationship between CO2 levels, oxygen delivery, and the internal pH of cells, offering a new perspective on the body’s intricate balance and how carbonated water might influence it.

The Unsung Hero of Anti-Inflammation & Relaxation

Beyond its potential in medical treatments, CO2 is gaining recognition for its anti-inflammatory properties and role in promoting relaxation and well-being ^(ref). Whether the increased CO2 in the air after a thunderstorm or the soothing effects of CO2-rich hot springs, there’s a growing awareness of how this gas influences our health.

Even the cosmetic industry is tapping into the benefits of CO2, incorporating it into creams for improved skin hydration and circulation. The humble glass of carbonated water might just be a vessel for many health benefits, from improved digestion and circulation to potential roles in cancer treatment and skin care.

As we continue to explore and understand the multifaceted effects of CO2, one thing is clear: those tiny bubbles carry a world of potential, making every sip of carbonated water a step towards understanding the complex symphony of our body’s inner workings.
