Take a baking soda bath to soothe sunburn naturally.

Your cupboards probably contain a number of sunburn treatments without you even knowing it. One product that you are likely to have on hand that can be very soothing to a sunburn is baking soda (sodium bicarbonate) - the same item you use to make your cookies rise and to deodorize your icebox! Add about a cup of baking soda to a bath filled with lukewarm water, and soak for as long as you desire. Try to make sure that all affected areas are submerged for this treatment to work best. Pour the bath water over your body using your hands or a soft wash cloth. Dab onto burned facial areas gently or splash the water directly onto your face. Rinse with cool water to remove any remaining grit, and moisturize with either after-sun lotion or aloe vera gel.
