Baking soda can soothe mild sunburn by neutralizing skin pH and reducing itching, but it’s not a cure for severe burns.
Understanding Sunburn and Its Effects on Skin
Sunburn is the skin’s inflammatory response to excessive ultraviolet (UV) radiation from the sun. This condition damages the outer layers of the skin, causing redness, pain, swelling, and sometimes blistering. The severity of sunburn varies depending on factors such as skin type, duration of exposure, and UV intensity. Mild sunburn often results in discomfort and peeling, while severe cases can lead to dehydration, infection risk, and long-term skin damage.
The main cause of sunburn is UVB rays, which penetrate the skin and damage DNA in skin cells. This triggers an immune response that results in inflammation. The damaged cells release chemicals that cause blood vessels to dilate, leading to redness and swelling. While the body repairs itself over time, immediate relief from symptoms is often sought through various home remedies.
How Baking Soda Interacts with Sunburned Skin
Baking soda, or sodium bicarbonate, is a common household item known for its alkaline properties. When applied to the skin, it can help neutralize acidity and soothe irritation. The alkaline nature of baking soda may counteract the slight acidity caused by inflammation in sunburned skin.
People often use baking soda baths or pastes to relieve itching and discomfort associated with minor skin irritations. Its mild antiseptic qualities might also prevent minor infections if the skin is broken or peeling due to sunburn. However, because baking soda is a base with a relatively high pH (around 9), improper use can disrupt the natural acid mantle of the skin—a protective layer that maintains moisture and defends against bacteria.
Application Methods for Baking Soda on Sunburn
There are two popular ways people apply baking soda for sunburn relief:
- Baking Soda Bath: Adding 1/4 to 1/2 cup of baking soda into a lukewarm bath helps soothe large areas of sunburned skin. Soaking for about 15-20 minutes may reduce itching and inflammation.
- Baking Soda Paste: Mixing baking soda with water to form a thick paste allows targeted application on smaller sunburn spots. This paste should be left on for about 10-15 minutes before rinsing off gently.
Both methods aim to calm irritated nerves and cool down inflamed tissue without causing further dryness or damage.
The Science Behind Baking Soda’s Effectiveness on Sunburn
Scientific research specifically focused on baking soda’s effect on sunburn is limited. However, its use in treating other inflammatory or itchy skin conditions provides insight into possible benefits:
- pH Regulation: Baking soda’s alkalinity can neutralize acidic compounds produced during inflammation.
- Anti-Itch Properties: It may relieve itching by calming nerve endings irritated by damaged skin.
- Mild Antiseptic Action: Sodium bicarbonate inhibits growth of some bacteria and fungi that could infect compromised skin.
Despite these potential benefits, dermatologists caution against overuse since excessive alkalinity may dry out the skin or worsen irritation if used improperly.
Baking Soda Versus Other Common Sunburn Remedies
Several remedies compete with baking soda for soothing sunburn symptoms:
| Remedy | Main Benefit | Potential Drawbacks |
|---|---|---|
| Aloe Vera Gel | Hydrates deeply; reduces inflammation with cooling effect | Possible allergic reactions; less effective if product contains additives |
| Cool Compresses | Immediate cooling; reduces heat sensation quickly | Temporary relief only; no long-term healing properties |
| Baking Soda Paste/Bath | Neutralizes acidity; relieves itching; mild antiseptic effect | May dry out or irritate sensitive skin if overused; limited scientific backing for severe burns |
| Corticosteroid Creams (Over-the-Counter) | Reduces inflammation significantly; controls itching effectively | Not suitable for broken/blistered skin; prolonged use risks thinning skin |
| Coconut Oil/Moisturizers | Keeps skin hydrated; promotes healing barrier formation | Can trap heat if applied too soon after burn; risk of clogged pores in some users |
Each remedy has its place depending on severity and individual tolerance.
The Risks and Precautions Using Baking Soda for Sunburn Relief
While baking soda offers notable benefits for mild irritation relief, it’s essential to understand risks before applying it extensively:
- Skin Dryness: Its alkaline nature can strip natural oils from the skin surface leading to dryness or cracking.
- Irritation or Burning Sensation: Some individuals experience increased stinging due to sensitivity or open wounds.
- Allergic Reactions: Though rare, allergic dermatitis could occur after topical application.
- Poor Healing Impact: Disrupting the acid mantle might delay natural healing processes if used excessively.
- Avoid Severe Burns: Baking soda should never replace medical treatment for blistered or second-degree burns requiring professional care.
Patch testing a small area before widespread use helps minimize adverse reactions.
The Best Practices When Using Baking Soda on Sunburns
To maximize benefits while minimizing harm:
- Dilute well: Use recommended amounts (e.g., a quarter cup per bath) rather than concentrated solutions.
- Avoid broken/blistered areas: Only apply paste or baths on intact but inflamed skin.
- Knead gently: Rinse thoroughly after application without scrubbing harshly.
- Moisturize afterward: Follow up with gentle lotions or aloe vera gel to restore hydration balance.
- If irritation worsens: Discontinue use immediately and seek medical advice if necessary.
These steps ensure safe integration into your sunburn care routine.
The Role of Hydration and Protection Alongside Baking Soda Treatment
Relieving symptoms is just one part of managing sunburn effectively. Hydration plays a crucial role in recovery because damaged skin loses moisture rapidly. Drinking plenty of water replenishes internal fluids supporting cellular repair.
Sun protection must continue even after initial treatment since newly healed areas remain vulnerable to UV damage. Wearing protective clothing, applying broad-spectrum sunscreen regularly (SPF 30+), and avoiding peak sunlight hours are essential habits post-sunburn.
Combining these preventive measures with soothing agents like baking soda ensures comprehensive care that addresses both symptoms and causes.

Frequently Asked Questions
Will Baking Soda Help Sunburn Itching?
Baking soda can help relieve itching caused by mild sunburn by neutralizing the skin’s pH and soothing irritation. Applying a baking soda paste or soaking in a baking soda bath may reduce discomfort and calm inflamed skin temporarily.
Will Baking Soda Help Sunburn Pain?
While baking soda may provide some relief from minor sunburn pain due to its cooling effect, it is not a painkiller. It helps soothe the skin but does not treat severe burns or underlying tissue damage.
Will Baking Soda Help Sunburn Healing?
Baking soda can aid in soothing and protecting mildly sunburned skin but does not speed up the healing process. It may help prevent minor infections if the skin is peeling, but proper medical care is necessary for severe sunburns.
Will Baking Soda Help Sunburn Redness?
Baking soda’s alkaline properties can help reduce inflammation and redness in mild sunburn cases by calming irritated skin. However, it should be used carefully to avoid disrupting the skin’s natural acid mantle, which protects against further damage.
Will Baking Soda Help Sunburn Blisters?
Baking soda is not recommended for treating sunburn blisters. Blisters indicate more severe skin damage that requires gentle care and possibly medical attention. Applying baking soda on broken or blistered skin may cause irritation or delay healing.
The Verdict – Will Baking Soda Help Sunburn?
Baking soda does offer tangible benefits in alleviating mild sunburn discomfort through pH neutralization and itch relief mechanisms. It’s an accessible option that many find calming when used correctly as a diluted bath soak or gentle paste. However, it isn’t a magic bullet—severe burns require professional treatment beyond home remedies.
Use baking soda cautiously—avoid overuse that could disrupt your delicate skin barrier—and always complement it with hydration and proper sun protection strategies. For stubborn pain, blistering, or systemic symptoms like fever or chills following sun exposure, consult healthcare providers promptly.
In summary: yes, baking soda can help ease mild sunburn symptoms but should be part of a broader approach focusing on gentle care and prevention rather than sole reliance.
