6. Soothe Itchy Skin and Sunburns
Baking soda is a good treatment for all kinds of skin ailments. It is especially good at taking the chronic itchiness and irritation out of bug bites and stings. For this, make a thick paste with baking soda and water and apply it to the affected areas.
If your itchy skin is the result of a sunburn, try a baking soda bath. Simply add 1-2 of baking soda to a warm (not hot) bath. Then soak for at least 30 minutes, making sure that the affected areas are completely covered. Some evidence suggests that sunburns respond even better when cornstarch and oatmeal are added to the bath as well.
