The topic at hand is about managing an ostomy in extreme heat, particularly focusing on controlling sweat, preventing rashes, and ensuring the security of the ostomy appliance. This is especially relevant for someone living in a hot climate like Arizona, where high temperatures can pose challenges for ostomates. Here are some practical tips and insights to help keep your pouch secure and your skin healthy during the hot season:

1. Minimize sweat under the wafer:
- Apply a thin layer of regular stick deodorant around the stoma before attaching the wafer. This can help reduce perspiration and odor.
- Use Sure Seal Rings, which are clear polyurethane barriers that overlay the wafer, to keep moisture out. These are especially useful for activities like swimming, workouts, and outdoor work.
- Consider adding a cloth pouch cover, such as commercial covers or inexpensive all-cotton baby bibs, to absorb sweat and keep the plastic bag off your skin.
- Wear a supportive back or abdominal brace with Velcro. This can help keep the pouch in place if the adhesive loosens, allowing you to change it when convenient.

2. Change and empty more often in hot weather:
- Reduce the wear-time of your appliance when temperatures exceed 90°F, as prolonged wear in sweaty conditions can lead to seal failure.
- Plan your meals so that your output is lighter during the hottest part of the day, and try to keep the pouch as empty as possible when you need to be outside.

3. Treat and prevent rashes, blisters, or fungal spots:
- Use Lotrimin antifungal foot powder on any yeast or fungus-type rash. Apply it, then "crust" it with a barrier wipe, add a little stoma powder, and crust again. Some find that Lotrimin alone is effective.
- For sweat blisters under the wafer, apply a small dab of Neosporin on the blister, cover it with a band-aid, and then apply the wafer over it.

4. Stay hydrated and replace electrolytes, especially if you no longer have a colon:
- Drink sports beverages like Powerade Zero to restore sodium, potassium, and other electrolytes while keeping sugar intake low.
- Increase your intake of plain water and watch for early signs of dehydration, such as fatigue, dizziness, and decreasing sweat output.
- Eat potassium-rich foods in addition to drinking electrolyte beverages.
- Try to schedule outdoor activities for early morning or late evening to avoid the extreme heat and humidity.
