Please choose the correct ending to complete the given sentence: Health: [header] How to control psoriasis [title] Fill a tub with lukewarm water. [step] Daily baths help remove scaly skin and calm the itching and burning associated with psoriasis. Make sure the water is not excessively hot-this can aggravate your symptoms.

Ending1: [title] Add a bath solution to the water. [step] Among the solutions found effective are epsom salts, dead sea salts, and oilated oatmeal. Ending2: Low-pressure water with a higher ph can also be helpful. If you live in an area where you experience tropical weather, get in a shower or bath that is not heated to the point of scalding. Ending3: Fill the tub with cool or lukewarm water. [substeps] Stick with lukewarm water-not hot-water will offer more relief than cold water because it constricts blood vessels for longer, eliminating the itching. Ending4: Fill the tub about 1/3 of the way with lukewarm water, but no more than 2/3. You shouldn't immerse yourself in water that is warmer than 103ºf, because that can cause the skin to become severely irritated.
