Key Facts

  • Widespread Condition: Eczema is a significant concern, affecting an estimated 31.6 million Americans with its characteristic symptoms of inflamed, dry, and intensely itchy skin.
  • Symptom Management, Not a Cure: It is critical to understand that baking soda cannot cure eczema. It serves as a natural, complementary therapy to help manage and soothe symptoms like itching and inflammation alongside prescribed treatments.
  • Authoritative Dosage Recommendation: The National Eczema Association specifically suggests adding about one-quarter cup of baking soda to a full, lukewarm bath to help soothe itchy, irritated skin.
  • The “3-Minute Rule” is Crucial: To maximize the benefits of any therapeutic bath, it is essential to apply a thick, fragrance-free moisturizer to damp skin within three minutes of patting dry to effectively seal in moisture.
  • A Rare but Serious Risk Exists: In very rare instances, excessive absorption of baking soda through the skin, particularly in infants or on open wounds, can lead to a dangerous condition called metabolic alkalosis, making medical consultation essential.

Does Baking Soda Actually Help Soothe Eczema?

Yes, baking soda can help alleviate eczema symptoms like itching and inflammation by adding it to a bath or using it as a paste. However, it is a complementary therapy to manage symptoms, not a cure for eczema. Many individuals suffering from the chronic skin condition, also known as atopic dermatitis, find that incorporating baking soda into their skincare routine provides welcome, temporary relief from the persistent discomfort. According to information reviewed by sources like Verywell Health and recommendations from the National Eczema Association, its use is a well-known home remedy for managing flare-ups. The key is understanding that this is a supportive measure, one piece of a larger eczema management plan that should be guided by a healthcare professional. For those with a compromised skin barrier, which is characteristic of eczema, finding safe ways to reduce irritation is a top priority, and a baking soda bath is a recognized method for achieving that calm.

The bottom line is clear: while not a cure, baking soda is widely acknowledged as a helpful tool for temporarily relieving the maddening itch and inflammation associated with eczema.

So, what is it about this common household item that can bring relief to irritated skin? The answer lies in its unique chemical properties, which interact with the skin and bathwater to create a more soothing environment. Let’s dive into the science behind how it works.

The Science: How Baking Soda Calms Eczema-Prone Skin

Baking soda helps soothe eczema with its natural antibacterial and anti-inflammatory properties, which can reduce itch and prevent infection on compromised skin. It can also help balance the pH of bath water, potentially reducing irritation. The effectiveness of baking soda, known scientifically as sodium bicarbonate (NaHCO₃), isn’t just anecdotal; it’s based on several key attributes that directly address the challenges of eczema-affected skin. When you’re wondering if can baking soda help eczema, understanding these mechanisms can give you confidence in how this simple compound works.

Eczema is more than just dry skin; it’s a condition where the skin barrier is damaged, making it less effective at retaining moisture and more susceptible to irritants. This compromised barrier often leads to an altered skin pH, which can worsen the cycle of itching and scratching. Here is exactly how baking soda intervenes to provide relief.

  • Antibacterial and Antifungal: The skin barrier in individuals with eczema is often cracked and broken, creating an entry point for bacteria and fungi. A secondary infection can significantly worsen a flare-up. Baking soda possesses natural antibacterial and antifungal capabilities that help keep the skin clean and reduce the risk of infection. Studies cited in the Journal of Integrative Dermatology have even shown its effectiveness against various fungal strains that can affect the skin and nails, making it a valuable cleansing agent for vulnerable skin.
  • Anti-inflammatory and Soothing: The hallmark of an eczema flare-up is inflammation and a persistent, often unbearable itch. Both research and widespread anecdotal evidence suggest that baking soda provides temporary itch relief and helps reduce this inflammation. Its soothing properties are often attributed to its ability to gently alter the chemistry of the bath water, creating a calming soak that eases irritation and allows the skin a moment of peace.

  • pH-Balancing Potential: Healthy skin has a slightly acidic pH. However, skin affected by eczema often has an increased pH level, meaning it has become more alkaline. This alkalinity can exacerbate inflammation and itchiness. While baking soda itself is an alkaline compound with a pH of about 9, adding a small, controlled amount to a large volume of bath water can help neutralize acidic water or slightly alter the overall pH, potentially bringing it closer to a level that is less irritating for the skin. It’s a delicate balance, as excessive use could have the opposite effect, which is why following proper dosage recommendations is crucial.

Quick Fact: Did you know? The pH of normal skin is slightly acidic, but eczema can make it more alkaline. Baking soda, while alkaline itself, can help balance the pH of your bath water.

By addressing these core issues—the risk of infection, inflammation, itch, and pH imbalance—baking soda provides a multi-pronged approach to symptom relief. This scientific foundation explains why so many people have found a baking soda bath to be an effective, accessible, and affordable part of their strategy to manage eczema.

How to Use a Baking Soda Bath for Eczema Relief: A Step-by-Step Guide

To take a baking soda bath for eczema, add one-quarter cup of baking soda to a lukewarm bathtub, soak for 10-15 minutes, gently pat the skin partially dry, and apply a thick moisturizer within three minutes to lock in moisture. Following this precise, expert-recommended process ensures you get the maximum soothing benefits while protecting your skin’s delicate barrier. This method is not just about adding baking soda to water; it’s a therapeutic routine where each step plays a critical role in calming irritation and hydrating the skin.

This step-by-step guide, aligned with recommendations from authoritative sources like the National Eczema Association, will walk you through the entire process, from preparing the perfect bath to crucial post-soak care. Think of this as your blueprint for turning a simple bath into a powerful tool for managing your eczema symptoms. Getting these details right can make a significant difference in how much relief you experience.

Pro Tip: For an extra soothing boost, consider adding colloidal oatmeal to your baking soda bath—a combination many find enhances relief.

Here’s exactly how to do it for the best results.

Step 1: Prepare the Bath

Fill a tub with lukewarm water (94-98.6°F) and dissolve one-quarter cup of baking soda for an adult or 2 tablespoons for a child’s half-full tub. The preparation phase is foundational to ensuring the bath is soothing rather than irritating. Getting the temperature and dosage right is non-negotiable for effective eczema care.

  • Set the Water Temperature: Your first action is to fill the bathtub with lukewarm water. The ideal temperature range is between 94 and 98.6 degrees Fahrenheit (34.4 to 37 degrees Celsius). Water that is too hot can strip the skin of its natural oils, worsening dryness and triggering an eczema flare-up. Therefore, never use hot water.
  • Measure the Baking Soda: For a standard, full-sized adult tub, measure out about one-quarter cup of baking soda. For babies or small children, the amount must be significantly reduced. Use approximately 1 teaspoon for a baby bathtub or 2 tablespoons for a standard tub that is half-full.
  • Dissolve Completely: Add the baking soda to the tub while the water is running and swish it around with your hand. This helps it dissolve completely, ensuring an even distribution in the water and preventing gritty particles from irritating the skin.

Step 2: Soak for the Right Amount of Time

Soak in the baking soda bath for 10 to 15 minutes. Avoid soaking longer than 20 minutes, as this can dry out the skin. While it may be tempting to linger in the soothing water, timing is everything when it comes to therapeutic bathing for eczema. The goal is to allow the skin enough time to benefit from the baking soda without becoming over-hydrated, which can paradoxically lead to more dryness once you get out of the tub.

For adults, the recommended soaking time is generally between 10 to 15 minutes, with an absolute maximum of 20 minutes. For children, a shorter soak of 10 minutes is often sufficient. Setting a timer can be a helpful way to ensure you don’t stay in too long. It’s important to understand the reasoning behind this guideline: prolonged exposure to water can be counterproductive and actually weaken the skin’s barrier, which is the exact opposite of what you want to achieve when managing eczema.

Step 3: Follow the “3-Minute Rule” After the Bath

After the bath, gently pat the skin leaving it slightly damp, and liberally apply a thick, fragrance-free moisturizer within three minutes to seal in moisture and protect the skin barrier. This final step is arguably the most critical part of the entire routine and is a cornerstone of eczema management. What you do immediately after the bath determines whether you lock in the hydration or let it evaporate, leaving your skin even drier than before.

Here is the precise post-bath checklist to follow every time:
1. Gently Pat Dry: Once you get out of the tub, resist the urge to rub your skin with a towel. Rubbing can cause friction and irritate sensitive skin. Instead, use a soft, clean towel to gently pat yourself partially dry. The goal is to leave the skin slightly damp.
2. Apply Medicated Ointments: If you have any prescribed medicated ointments or creams from your doctor, apply them immediately to the affected areas as directed.
3. Moisturize Liberally: This is where the “3-Minute Rule” comes into play. Within three minutes of patting dry, apply a generous amount of a thick, fragrance-free moisturizer to your entire body. Ointments and creams with high oil content are generally more effective than thinner lotions for trapping moisture.
4. Allow Absorption: Wait for about five minutes before getting dressed to allow the moisturizer to fully absorb into your skin without being rubbed off by clothing.

The “3-Minute Rule” is a guideline strongly recommended by dermatologists for eczema care. It emphasizes the short window of opportunity you have after bathing to apply moisturizers while your skin is most receptive. This simple action traps water from the bath in the upper layers of your skin, providing crucial hydration and helping to repair the skin barrier.

By diligently following these three steps, you can safely and effectively use a baking soda bath as a powerful natural remedy to calm the uncomfortable symptoms of eczema.

Using a Baking Soda Paste for Targeted Itch Relief

For localized eczema patches, mix baking soda with a few drops of water to form a thick paste, apply it to the affected area for 2-3 minutes, then rinse thoroughly and moisturize. While a full-body soak is excellent for widespread irritation, sometimes you need a more targeted approach for a single, intensely itchy spot. In these situations, a baking soda paste is a simple and effective alternative. This method delivers a concentrated soothing effect directly where it’s needed most.

This approach is particularly useful for small, accessible flare-ups and can be a quick way to get relief without drawing a full bath. Showing an understanding of this specific application demonstrates a nuanced approach to managing eczema symptoms. Here is how to create and use a baking soda paste safely.

  1. Preparation: In a small bowl, place a few tablespoons of baking soda. Add water, a few drops at a time, and mix until you create a thick, mud-like consistency. The paste should be thick enough that it will stay on the skin without sliding off.
  2. Application: Gently apply the paste directly to the itchy or inflamed areas of skin. Be careful not to rub or scrub, as this will cause further irritation. Leave the paste on the affected area for no more than two to three minutes.
  3. Rinsing and Moisturizing: After the time is up, rinse the paste off completely with lukewarm water. Gently pat the area dry with a soft towel, leaving it slightly damp. Immediately follow up by applying your regular thick, fragrance-free moisturizer to the treated areas to hydrate the skin.

Using a paste is an excellent tool in your eczema care toolkit, but just like with baths, it’s essential to prioritize safety by following instructions and listening to your skin.

Safety First: Important Precautions and Potential Risks

Always consult a dermatologist before using baking soda for eczema, especially for children. Perform a patch test first, avoid use on open wounds, and be aware of the rare risk of metabolic alkalosis from excessive absorption. While baking soda is a generally safe, natural remedy, it is not without potential risks, particularly for those with the highly sensitive and compromised skin associated with eczema. Prioritizing safety is paramount to ensure your efforts to find relief don’t inadvertently cause more harm. Your health and safety are the top priority.

Before you begin incorporating baking soda baths or pastes into your routine, it is absolutely essential to understand and respect these precautions. This information is provided to empower you to make safe choices and demonstrates a high level of trustworthiness by being transparent about potential side effects.

  • Always Consult a Doctor: This is the most important rule. Before trying any new home remedy, including baking soda, you must consult with your dermatologist, allergist, or pediatrician. This is especially critical if your eczema is severe or if you are considering using it for a child. A healthcare provider can offer guidance tailored to your specific condition and health history.
  • Perform a Patch Test: Before applying a paste or taking a full bath, test the baking soda on a small, unaffected patch of skin, like your inner arm. Apply a small amount of the paste or soak the area in a concentrated solution, rinse it off after a few minutes, and wait 24 hours to see if any adverse reactions like redness, burning, or increased itching occur.
  • Avoid on Open Wounds: Do not use baking soda baths or pastes on skin with large, open wounds or serious infections. While baking soda has mild antibacterial properties, applying it to broken skin can cause significant stinging and irritation and may increase the risk of absorption into the bloodstream.
  • Be Aware of Potential Skin Irritation: Although it is uncommon, some individuals may have a sensitivity or an unknown allergy to baking soda. If you experience any irritation, increased redness, or worsening of symptoms, discontinue use immediately.
  • Use in Moderation: Overusing baking soda can disrupt your skin’s natural pH balance and strip its protective oils, leading to increased dryness and irritation over time. Stick to the recommended amounts and frequencies discussed with your doctor.
  • Know the People Who Should Be Extra Cautious: Individuals who are pregnant or nursing, or those with pre-existing conditions like high blood pressure or diabetes, should get explicit approval from their doctor before using baking soda baths.

Serious Warning: Metabolic Alkalosis
In extremely rare cases, excessive absorption of sodium bicarbonate through the skin can lead to a dangerous medical condition called metabolic alkalosis, where the body’s pH becomes too alkaline. This risk is highest for infants, young children, and individuals with extensive open wounds. Symptoms include confusion, hand tremors, nausea, vomiting, lightheadedness, and muscle twitching. If any of these symptoms occur, seek immediate medical attention.

By adhering to these safety guidelines, you can confidently explore whether baking soda can help your eczema in the safest way possible.

FAQs About Using Baking Soda for Eczema

Is it safe to use baking soda for my baby’s eczema?

Always consult a pediatrician before trying any home remedy on a baby. If approved, use a much smaller amount, such as 1 teaspoon for a baby bathtub, and be extra vigilant for any signs of irritation. A baby’s skin is far more delicate and permeable than an adult’s, which increases the risk of both irritation and systemic absorption. Safety is the absolute priority, and professional medical advice is non-negotiable.

How much baking soda should I use for an itchy skin bath?

The generally recommended amount is one-quarter cup of baking soda for a standard, full-sized adult bathtub filled with lukewarm water. This concentration is considered effective for soothing the skin without being overly harsh. Using more is not better and can lead to excessive dryness or irritation. For smaller tubs or children, this amount should be reduced accordingly.

Can I use a baking soda paste on my face?

While a paste can be used for localized spots, the skin on your face is more sensitive. It is crucial to perform a patch test on a discreet area first and consult a dermatologist before applying baking soda to your face. The potential for irritation or an adverse reaction is higher on facial skin, so extreme caution is warranted. Never apply it near your eyes.

What are the main side effects of a baking soda bath?

While generally safe, potential side effects include skin irritation or dryness if overused. In very rare cases, excessive absorption through broken skin could lead to a serious condition called metabolic alkalosis. Most people experience no side effects when following proper guidelines. However, if you notice any increased redness, burning, or discomfort, you should discontinue use and consult your doctor.

What is the 3-minute rule for eczema I keep hearing about?

The “3-minute rule” is a guideline recommended by dermatologists to apply moisturizer to the entire body within three minutes of bathing or showering. This helps to lock in the moisture from the bath before it evaporates from the skin. This simple but powerful step is one of the most effective ways to combat the dryness associated with eczema and maximize the benefits of any therapeutic bath.

Final Summary: Key Takeaways for Using Baking Soda on Eczema

In the ongoing effort to manage eczema, baking soda has firmly established itself as a valuable, accessible, and effective tool for temporary symptom relief.
