Drink fluids to stay healthy on the road
Rough travel and extreme sports can quickly dehydrate your body, especially in hot, dry climates such as the American Southwest or East Africa. Stock up on purified, bottled water in areas where a safe source may not exist. As a backup, carry oral rehydration solutions (ORS), which typically contain salts and a simple sugar such as glucose, to counter intestinal disorders and heat exhaustion.
T+L Recommends: Eastern Mountain Sports sells oral rehydration salts and portable ultraviolet water purifiers. On flights, skip sugary, caffeinated soft drinks from the beverage cart for healthier green tea, which contains immune-boosting, detoxifying polyphenol compounds.
