Bathe in baking soda

- Adding baking soda to a bath may help soothe irritated skin. A 2004 study looked at the effects of baking soda (sodium bicarbonate) on 31 people with mild to moderate psoriasis. Those that bathed in a baking soda bath reported improvements in skin itching and irritation.

- However, a 2019 study on 30 people found that applying baking soda topically to areas of psoriasis was not effective. Scientists need to do further research into the benefits of baking soda for easing skin irritation.
