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
喝起來！
一個(gè)新的調(diào)查顯示很多孩子沒有喝足夠量的水
作者：Zachary Humenik (時(shí)代周刊少兒版)
夏天近在咫尺了, 天氣也越來越熱。你喝了足夠量的水了嗎？根據(jù)美國公共健康雜志最新發(fā)表的調(diào)研表示，大多孩子并沒有攝入充足的水分。
這項(xiàng)調(diào)研的主導(dǎo)者是哈佛公共衛(wèi)生學(xué)院的科學(xué)家艾莉卡.肯尼，她原本是想調(diào)查孩子們?cè)趯W(xué)校會(huì)攝入多少含糖的飲料，但她的調(diào)研卻發(fā)現(xiàn)大多孩子在學(xué)校很少喝水。
在2009年至2012年期間，肯尼和她的團(tuán)隊(duì)研究了4000名年齡在6-19歲的孩子的數(shù)據(jù)，這些數(shù)據(jù)來源于國家健康及營養(yǎng)調(diào)研報(bào)告，該報(bào)告是每年由美國疾病預(yù)防控制中心制作的。
在瀏覽報(bào)告后，她發(fā)現(xiàn)參與調(diào)研的孩子中，處于缺水狀態(tài)的超過半數(shù)。在報(bào)告數(shù)據(jù)中，男孩比女孩體內(nèi)缺水的可能性高出76%。有近四分之一的孩子根本就不喝水。
“這些發(fā)現(xiàn)很重要，因?yàn)樗鼈冏屛覀冴P(guān)注到以往忽略了的健康隱患，”肯尼在發(fā)表的聲明中如是說，“盡管對(duì)于大多孩子來說，這不會(huì)立即對(duì)健康有很大的影響，但這個(gè)問題的確會(huì)對(duì)孩子和青少年的體質(zhì)和健康造成不利?！?/p>
喝多少水才能滿足健康需求呢？
人體60%是由水構(gòu)成的，它能夠調(diào)控體溫，將氧氣輸送給身體，幫助消化，在各個(gè)方面發(fā)揮著作用，讓我們的身體保持健康。
沒有攝入足夠的水分會(huì)導(dǎo)致健康問題，如頭痛、易怒、體能差甚至更嚴(yán)重的問題。天氣炎熱的環(huán)境下、運(yùn)動(dòng)時(shí)和發(fā)燒時(shí)，你的身體需要更多的水分。
美國國家農(nóng)業(yè)圖書館表示平均來說，每個(gè)孩子每天要喝10-14杯水。這個(gè)量也包括攝入含有大量水分的食物，比如芹菜、甜瓜或者西紅柿。此外，用高卡路里的含糖飲料來取代水的攝入，會(huì)導(dǎo)致肥胖問題。
補(bǔ)充水分的小竅門
以下是美國疾控中心給大家的補(bǔ)水小竅門：
-隨身帶著水壺
-在可用于冷凍的杯子中冷凍一些水，這樣第二天帶著，整天就可以有冰水喝
-不要用飲料來代替水
-在外吃飯時(shí)也喝水來代替飲料，這樣不但省錢，還健康
-可以在白水中加點(diǎn)料，如幾片酸橙和檸檬。這樣不但可以提升口感，你也更愿意多喝水
