1. Natural Deodorant
If you want to avoid the parabens and aluminium found in many deodorants and antiperspirants, try a pinch of baking soda mixed with water instead. This simple paste makes an effective and simple natural deodorant. You can also simply brush some dry baking soda under your arms.
2. Insect Bites and Poison Ivy
Apply a paste made of baking soda and water to insect bites to help relieve itching. You can also try rubbing the dry powder onto your skin. This is also effective for itchy rashes and poison ivy. Baking soda helps to relieve minor skin irritation and itching by neutralizing toxins and irritants on your skin's surface.2
3. Heartburn, Indigestion, and Ulcer Pain
Most over-the-counter antacids contain some form of bicarbonate. Baking soda works by immediately neutralizing stomach acid, helping to relieve heartburn, indigestion and even ulcer pain. I have personally recommended this to many, including family members, and have been surprised how remarkably effective it is.
Dosing is typically ½ teaspoon fully dissolved in a half a glass of water, taken every two hours (do not take more than seven ½ teaspoons in 24 hours, or three ½ teaspoons if you're over 60)
This should only be used as an occasional (not chronic) treatment, however, and be careful not to consume excessive amounts, which can cause serious electrolyte and acid/base imbalances
4. Foot Soak and Exfoliator
Add three tablespoons of baking soda to a tub of warm water for an invigorating foot soak. You can scrub your feet with a baking soda paste for additional exfoliation. A paste made from three parts of baking soda combined with one part water can be used as an exfoliator for your face and body, too. It's natural, inexpensive and gentle enough to use every day.
5. Relaxing Soak
Baking soda and apple cider make a wonderful spa-like bath for soaking. It also cleans the tub and the drain, as a bonus!
6. Hand Cleanser
Mix three parts baking soda with one part of water to make a natural hand cleanser that will scrub away dirt and neutralize odors.
7. Splinter removal
Add a tablespoon of baking soda to a small glass of water, then soak the affected area twice a day. Many splinters will come out on their own after a couple of days using this treatment.
8. Sunburn Remedy
Add ½ cup of baking soda to lukewarm bathwater, then soak in the tub for natural relief. When you get out, let your skin air dry, rather than towelling off the excess baking soda, for extra relief. You can also add a mixture of baking soda and water to a cool compress and apply it to the sunburn directly.
9. Enhanced Sports Performance
Distance runners have long engaged in a practice known as "soda doping" -- or taking baking soda capsules -- before races to enhance performance, a measure that's thought to work similarly to carbohydrate loading. It's also been shown to improve speed among swimmers
10. Tooth and Gum Paste
Baking soda has a mild abrasive action that helps to remove plaque and polish, clean, and deodorize your teeth
