This topic is about finding ways to keep ostomy pouches secure in extreme heat and sweat, especially for someone living and working outdoors in a hot climate like Oman. The challenge is that high temperatures and physical activity can cause heavy sweating, which makes the adhesive on the pouch fail. Here are some helpful tips and insights to tackle this issue:

1. Consider using extended-wear or "deluxe" versions of barriers or wafers. Many manufacturers, such as Hollister, Convatec, and Coloplast, offer these longer-wear options.

2. If necessary, try switching brands or models. Some users have found success with products like the Convatec Stomahesive Extended Wear One-Piece Active Life Drainable Pouch, which withstands heat well.

3. Add an Eakin Cohesive Seal or a similar barrier ring for extra adhesion and leak protection.

4. Use Skin-Tac, either in liquid form or as a wipe, on clean, dry skin to create a tacky surface before applying the wafer.

5. Employ skin-prep or gel dressing wipes that leave a sticky film. Make sure to let them dry completely before attaching the wafer. Many users recommend Hollister Skin Gel Dressing Wipes.

6. Clean the area with non-moisturizing, non-perfumed products. Some users prefer Hollister Universal Adhesive Remover Wipes for cleaning, followed by thorough drying.

7. For mechanical support in heavy sweat, consider:
- Wearing an elastic ostomy belt that clips to most convex pouches.
- Applying two strips of 2-inch surgical tape or Perma-Type two-inch pink tape across the top and bottom edges of the wafer.

8. Switching from a one-piece to a two-piece Hollister wafer-and-pouch system can help prevent blow-offs in hot weather.

9. Users have reported success with these methods in temperatures over 90 °F (32 °C) while engaging in activities like running, cycling, golfing, swimming, and even in hot tubs and humid environments like Hawaii.

10. If a particular skin-prep, such as Convatec AllKare, interferes with adhesion, try experimenting with alternatives. Some users found Hollister skin barrier wipes effective when others failed.

These tips aim to help keep your ostomy pouch secure and comfortable, even in challenging conditions.
