Me in Thailand, a VERY HOT country! The Sun: Clearly an Enemy 1. Ultra-Hydrating Drinks Firstly drink lots of plain regular trusty WATER. Secondly, specialty drink such as this aloe vera juice with lime and honey as well as Pocari Sweat are VERY hydrating and tasty. Thirdly, the OS-1 is a drink specifically designed to combat DEHYDRATION! If you're suffering from heat exhaustion or even just sick with the flu, get this stuff!!! [ NOT a substitute for seeking medical help in cases of extreme heat stroke, etc.] 2. Cold Drinks Cold drinks are wonderful, but for every iced coffee or tea you enjoy, remember to drink additional water to compensate for the caffeine (a diuretic, which can also increase thirst). Bonus if your drink has ice cubes because you can suck on the ice and/or drink the melting ice water after your juice is finished. Even putting ice in beer is common in extremely hot countries. It also counteracts the effects of heat + alcohol
