Staying healthy on a multi-day bushwalk is just as important as packing the right gear. A dodgy stomach can ruin a trip fast, but a few simple habits will help you avoid diarrhoea out on the trail.
First up, always treat your water. Even the clearest streams can carry bacteria or parasites. Boil it, filter it, or use purification tablets—whatever method you trust, just don’t skip it.
Second, keep your hands clean. It sounds obvious, but it’s one of the biggest causes of stomach bugs. Wash with biodegradable soap when you can, especially after going to the toilet and before eating. If water’s scarce, hand sanitiser is your backup.
Third, be smart with food. Make sure meals are properly cooked and don’t let food sit around for too long, especially in warm weather. Keep things sealed and separate—no one wants cross-contamination in the bush.
Fourth, go to the toilet the right way. Head at least 100 metres away from campsites, tracks, and water sources. Dig a small hole, do your thing, and cover it up properly. It keeps the area clean and reduces the risk of spreading bugs.
Finally, stick to foods you know work for you. A bushwalk isn’t the best time to experiment with new snacks or drastically change your diet. Keep it simple and reliable.
Follow those basics and you’ll cut your chances of getting sick by a lot—meaning you can focus on the walk, not your stomach.
