When you're thirsty and in need of a drink, which beverages are best at keeping you hydrated? Sure, you can always reach for a glass of water -- but plain H20 isn't the most hydrating beverage around, according to a study from Scotland's St. Andrews University that compared the hydration responses of several different drinks. The researchers found that while water -- both still and sparkling --does a pretty good job of quickly hydrating the body, beverages with a little bit of sugar, fat or protein do an even better job of keeping us hydrated for longer. The reason has to do with how our bodies respond to beverages, according to Ronald Maughan, a professor at St. Andrews' School of Medicine and the study's author. One factor is the volume of a given drink: The more you drink, the faster the drink empties from your stomach and gets absorbed into the bloodstream, where it can dilute the body's fluids and hydrate you. The other factor affecting how well a beverage hydrates relates to a drink's nutrient composition. For example, milk was found to be even more hydrating than plain water because it contains the sugar lactose, some protein and some fat, all of which help to slow the emptying of fluid from the stomach and keep hydration happening over a longer period of time.

The same can be said for oral rehydration solutions that are used to treat diarrhea. Those contain small amounts of sugar, as well as sodium and potassium, which can also help promote water retention in the body. The research team at St. Andrews University tested 13 common beverages to see how they impact hydration. Here's what they found, ranked from most hydrating over a four-hour period to least.

我是喝冰水
就想喝甜水，身体自然反应
道理上来讲口渴是盐浓度高了引起的，所以想喝甜水
默默地提醒，年纪不小了。。。。。
这个最不解渴
绝对是，这种研究谁信谁傻
我喝可乐越喝越渴

蜂蜜水
我觉得带些电解质或矿物质的饮料解渴
