@AlexisLander - I honestly never thought about how the weather might impact my ostomy until I read Brittney's post. I think a general tip regardless of the weather, is to use some sort of minimal heating device - heating pad, blow dryer - to provide some heat to your wafer when it is initially applied. Only 10 or 15 seconds on a low heat can assist with the adhesive. I have done this for years but other than that I have personally not noticed any other issues. I would suggest that supplies are kept in an area that is temperature controlled and near room temp. Linda Urbanski (moderator, Bladdercancer.net team member)
