What to Drink?
In addition to water, try mixing things up with fruit spritzers or teas. These will give you some variety and therefore may motivate you to drink more. Avoid lemonades, however, due to their high sugar content. Coffee may be consumed in moderation.
How Much to Drink?
The latest research has indicated that the previously recommended eight glasses of water per day for everyone appears to be a myth. In other words, researchers have found that drinking excessive amounts of water will not necessarily add health benefits. Therefore, a good rule of thumb is to drink whenever you are thirsty, unless you are doing strenuous exercise or live in a hot, dry climate. Also, it is best to drink water over the course of the day, because your intestines can only absorb .2 litres every half an hour. One final tip: Leave fluids in plain view (i.e., on your desk) so that you are more apt to drink.
