Once a heel blister starts to get better/heal, does keeping it exposed to air each night (so the area dries after the day of hiking) improve healing, or is keeping the area moist and soft with a dressing better?
Submitted by – Jens, Washougal, WA
Wounds, on heels or anywhere else, do not like to dry out. I can’t quote hard science, but my educated guess is that wounds with a dry surface will take 3 to 4 times longer to completely heal than wounds that have been kept moist with a proper dressing.
And the chance of scarring is greater with dry wounds—if that matters to you. I strongly recommend keeping the area moist with a proper dressing, a dressing that holds in the body moisture of the blistered area.—BUCK
