Drink up!
- A new studyshows that many kids aren’t drinking enough water
By Zachary Humenik （Time for Kids)
Summer is almost here, and the weather is heating up. Are you drinking enough water? Many kids aren't, according to a new study published in the American Journal of Public Health.
The study's lead author, Erica Kenney, a scientist at Harvard's T.H. Chan School of Public Health, originally planned to look into the amount of sugary drinks kids were consuming in schools. However, during her research she found that many kids were simply not drinking enough water.
Kenney and her team examined data from a group of 4,000 children, ages 6 to 19, between the years of 2009 and 2012. The data was taken from the National Health and Nutrition Survey, a study on the health of children in the United States conducted each year by the Center for Disease Control and Prevention.
While looking through the survey results, she noticed that more than half of the kids who participated were dehydrated. Of that group, boys were 76% more likely than girls to not have enough water in their system. Nearly one quarter of the kids in the survey reported drinking no plain water at all.
"There findings are significant because they highlight a potential health issue that has not been given a lot of attention in the past," Kenney said in a statement, " Even though for most of these kids this is not an immediate, dramatic health threat, this is an issue that could really be reducing quality of life and well-being for many children and youth."
How much is enough?
The human body is made up of 60% water. It regulates body temperature, delivers oxygen all over the body, assists in digestion, and performs various other tasks that keep our bodies healthy.
Not drinking enough water can lead to health problems such as headaches, irritability, poor physical performance, and even more serious issues. Your body needs more water when you are in hot climates, when you are physically active, and if you have a fever.
The United States National Agriculture Library says on average, kids need between 10 to 14 cups of water every day. This water can come from a mix of drinks and foods that contain high amounts of water, such as celery, melons, or tomatoes. It is also recommended that fluids come from water instead of sugary drinks that are high in calories and can lead to weight problems.
Tips for staying hydrated
The United States Center for Disease Control offers the following tips for people to stay hydrated:
- Carry a water bottle for easy access
- Freeze some freezer-safe water bottles. Take one with you for ice-cole water all day long.
- Choose water instead of sugar-sweetened beverages
- Choose water instead of other beverages when eating out. Generally, you will save money and reduce calories
- Give your water a little pizzar by adding a wedge of lime or lemon. This may improve the taste, and you just might drink more water than you usually do
喝起来！
一个新的调查显示很多孩子没有喝足够量的水

夏天近在咫尺了, 天气也越来越热。你喝了足够量的水了吗？根据美国公共健康杂志最新发表的调研表示，大多孩子并没有摄入充足的水分。
这项调研的主导者是哈佛公共卫生学院的科学家艾莉卡.肯尼，她原本是想调查孩子们在学校会摄入多少含糖的饮料，但她的调研却发现大多孩子在学校很少喝水。
在2009年至2012年期间，肯尼和她的团队研究了4000名年龄在6-19岁的孩子的数据，这些数据来源于国家健康及营养调研报告，该报告是每年由美国疾病预防控制中心制作的。
在浏览报告后，她发现参与调研的孩子中，处于缺水状态的超过半数。在报告数据中，男孩比女孩体内缺水的可能性高出76%。有近四分之一的孩子根本就不喝水。
“这些发现很重要，因为它们让我们关注到以往忽略了的健康隐患，”肯尼在发表的声明中如是说，“尽管对于大多孩子来说，这不会立即对健康有很大的影响，但这个问题的确会对孩子和青少年的体质和健康造成不利。”
喝多少水才能满足健康需求呢？
人体60%是由水构成的，它能够调控体温，将氧气输送给身体，帮助消化，在各个方面发挥着作用，让我们的身体保持健康。
没有摄入足够的水分会导致健康问题，如头痛、易怒、体能差甚至更严重的问题。天气炎热的环境下、运动时和发烧时，你的身体需要更多的水分。
美国国家农业图书馆表示平均来说，每个孩子每天要喝10-14杯水。这个量也包括摄入含有大量水分的食物，比如芹菜、甜瓜或者西红柿。此外，用高卡路里的含糖饮料来取代水的摄入，会导致肥胖问题。
补充水分的小窍门
以下是美国疾控中心给大家的补水小窍门：
-随身带着水壶
-在可用于冷冻的杯子中冷冻一些水，这样第二天带着，整天就可以有冰水喝
-不要用饮料来代替水
-在外吃饭时也喝水来代替饮料，这样不但省钱，还健康
-可以在白水中加点料，如几片酸橙和柠檬。这样不但可以提升口感，你也更愿意多喝水
