Drinks are important for meeting your daily hydration needs. Especially in today’s over heated environment, it is crucial to stay hydrated through the day. Drinking enough water can help you feel less thirsty and more alert; this provides increased energy levels to work or play. Some other popular beverage options that are hydrating include unsweetened herbal/vegetable teas like green tea, black coffee (without cream, sugar, or milk), and hot cocoa (unsweetened). In general, beverages provide about 3-5 servings of fluid per glass. The best gauge of the percentage of water a drink contains is by its weight or volume – if a carton says it has 64 ounces, then it must.
