Use Baking Soda:
Baking soda helps effectively in soothing the itchy and irritated skin. Sodium bicarbonate in baking soda helps in providing relief from the burning and itching sensation. Furthermore, baking soda is one of the key ingredients that we mostly use in our kitchen as the availability is of no issue, so it makes a great home remedy for treating heat rash and other skin conditions, which cause irritation on the surface of the skin. Add 3-5 tablespoons of baking soda in a lukewarm water bath then soak for about 20 minutes. The use of baking soda also heals the creases happening on the skin due to all the scratching.
