Once you become an adult,you typically reach your full height. But your height can change with age,and it's no myth — you shrink with time.
人在成年之时,通常身高会达到顶点。但是你的身高会随着年龄而改变,年纪大了就会变矮,这并不是什么秘密。
People usually lose about a centimeter in height every 10 years after age 40,according to Medline Plus,and that pace of height loss speeds up after age 70. Overall,you can lose between 1 to 3 inches in height as you age,per Medline Plus.
医学网站Medline Plus称,在40岁后每过十年人的身高通常会缩水1厘米左右,70岁后身高缩水速度会加快。总体来看,人在年老后身高会缩水1到3英寸(2.5到7.6厘米)。
人老了之后最少要变矮五六公分吧,爸爸年轻的时候身高有一米七零吧,现在已经八十多岁了,身高也就剩下一米六五左右,和年轻的时候比要矮五六公分吧,老人常说,人老了就会缩缩啦,现在看来这句话是对的,不知自己老了。
While age-related height loss is normal,there are times when it's a sign of an underlying health condition.
尽管人老了变矮是正常现象,但是有时候也预示着潜在的健康问题。
Why do you get shorter as you age?
为什么人老了会变矮?
On a macro level,you get shorter as you age due to changes in the bones,muscles and joints. "There are a few different things going on here," Dr. Angela Catic,a geriatrician and associate professor in the Huffington Center on Aging at Baylor College of Medicine,tells Yahoo Life. One,she says,is that the discs between the vertebrae in your spine lose fluid as you get older. "They become dehydrated and,with that,they lose height — and you lose a bit of height," she says.
而且人的外貌特征也会发生相应的变化,比如脸上出现皱纹、身体发福,亦或者是身高变矮等,临床发现,40岁以后,大部分人的身高每10年会减少约1厘米,80岁以上的人的身高会比年轻时下降10~15厘米左右 。
从宏观层面来看,人在衰老时会因为骨骼、肌肉和关节的变化而变矮。美国贝勒医学院赫芬顿衰老研究中心的老年病学专家、副教授安吉拉·卡蒂克博士告诉雅虎生活频道:“有几种不同情况。”一种情况是,年纪大了以后,脊柱椎间盘所含的液体会减少。她指出:“脊柱椎间盘脱水后会变短,从而让你变矮。”
Abdominal muscles also tend to weaken over time,which can create a stooped posture,causing you to appear shorter,Catic says.
卡蒂克说,另一种情况是,腹部肌肉随着时间流逝会衰弱,从而会导致驼背,让你看起来更矮。
190老了身高会变矮2-5cm。年纪大了身高会缩多少,具体需要根据个人身体情况判断,通常会缩2-5cm,主要与进食减少、骨质疏松、腰间盘退化等因素相关。建议中老年人平时多注意饮食卫生,吃饭时要细嚼慢咽,尽量选择清淡、易消。
In women,menopause can speed up bone loss "due to the loss of the protective effects of estrogen on bones," Dr. Arashdeep Litt,an internal medicine physician with Spectrum Health,tells Yahoo Life. That,too,can cause you to get shorter.
一般60岁之后身高会降低3-5厘米 因为60岁的时候身体都还可以 ,尤其现在 只要没有什么大病,身体都算硬朗 不会出现以前一到60岁就弯腰驼背的情况 所以不可能降低7——8厘米的 放心吧 。
健康机构Spectrum Health的内科医生艾拉什迪普·利特博士告诉雅虎生活频道,女性绝经会加速骨质流失,因为“雌性激素对骨骼的保护作用减弱了”,这也会令其变矮。
但是利特指出,变矮也可能是由骨质疏松导致的,骨质疏松指的是骨密度和骨量下降,或骨骼质量或结构发生改变。美国国立卫生研究院称,这会降低骨骼强度,增加骨折风险。
据一些资料介绍 ,一般60岁之前变化不明显,60岁之后至75岁左右时会因人而异比年轻时矮2公分左右,80岁以上的人身高比年轻时下降10一15厘米。人的身长在一昼夜间也是有是变化的:早上最长,晚上最短,相差2—
如何区分正常的身高缩水和骨质疏松症?
之所以人老了身高会变矮,是因为人是由60万亿个细胞组成的,人生活了很多年,在老了以后,身体的细胞就会慢慢的萎缩没有弹性,一个细胞在萎缩的时候,我们感觉不出身体变矮了,但是整个身体的细胞都在变萎缩,那么人就会明。
So,how can you know what's behind your shrinking size? Your doctor will suspect osteoporosis if you have an overall height loss of 1.5 inches or more,Litt says. "This much height loss is a sign of osteoporosis and warrants a bone density test," she says.
那么,怎么知道是什么原因导致自己变矮的呢?利特说,如果你身高缩水总量超过1.5英寸(3.8厘米),你的医生就会怀疑你得了骨质疏松症。她指出:“身高缩水这么多是骨质疏松的迹象,需要进行骨密度测试。”
这种测试可以测出你的骨强度,并确定你是否有骨质疏松症,以及未来发生骨折的风险。
How to prevent height loss
如何预防身高缩水
Again,some height loss is normal. But Catic says you can lower your risk of height loss by doing the following:
年纪大了变矮一些是正常的。但是卡蒂克指出,你可以通过做以下几件事来降低身高缩水风险:
Exercise regularly.
定期锻炼
Lift weights (this,along with regular exercise,stresses your bones and makes them stronger).
举重(举重和定期锻炼都能强健骨骼)
Eat a diet rich in calcium and vitamin D to support bone health.
摄入有助于骨骼健康的富含钙和维生素D的膳食
Avoid smoking,excessive alcohol use and excessive caffeine intake — all of which are risk factors for osteoporosis.
避免吸烟、酗酒和过量摄入咖啡因,这些都是导致骨质疏松的风险因素
