一番欲しいものは、手に入らないもの。 人が最も恋しく思うのは、失ったものである。
許多爸爸媽媽會擔心自己孩子的身高，特別是對那些本身身高較矮的父母來講，更是如此。有沒有什麼後天的辦法能夠幫助寶寶長個子呢？
答案是肯定的，除了遺傳因素對身高有影響之外，後天如果能夠經常運動，也能夠幫助孩子長個子！
許多因素會影響身體長高，盡管遺傳占的比例很大，但不是百分之百決定著人們的身高。專家研究表明，在影響身高的因素當中，遺傳因素占到了百分之三十三，而如果能夠經常運動可以占到20%，營養占31%，生長環境占16%。
人的身高是由骨骼的生長發育決定的。在長骨的兩端，有一種負責骨骼生長的骺軟骨。還沒成年的時候骺軟骨逐漸生長促進骨骼不斷增長；成年後生長停止，人們的個子也就不再生長。當骺軟骨還在生長期間，常常進行適量的體育運動，有助於骺軟骨的繼續成長。所以，對於孩子來講，體育鍛煉是促使孩子長高十分有效的方法之一。
除此以外，常常進行體育運動能改進人體的血液循環，促進身體對營養要素的吸收效率，提升骨細胞的成長效率；機械力可幫助骨鈣發生沉澱，讓骨骼更厚實。根據醫學專家的研究調查，對於那些常鍛煉的孩子來說，他們的身高普遍會高出4至8厘米，高於同齡的孩子。科學家建議，青春期的孩子應該每天鍛煉不少於1小時。什麼體育項目有助於長高？
通常來講，最好的運動方式包括跳躍，奔跑，以及自由體操，另外，打籃球，打排球，遊泳，跳繩，引體向上等運動也對長高很有效。跑，跳，負重運動，它們都可以對肌肉和韌帶有伸展作用，並促進骺軟骨的生長；引體向上還能夠舒展脊柱，讓脊柱更好地生長，遊泳的時候蹬夾腿的動作包括水的浮力，對身體的生長也十分有好處。
一項強度很大的運動，如體育競賽或者力量運動，每次鍛煉得時間間隔要久一些，而總的鍛煉時間不要太長，避免太過勞累；不太累的項目，如慢跑，跳繩等，鍛煉時間可以長一些，肌肉，關節和骨骼可以得到充分的激發。
值得重視的是，人的身高還受到內分泌的作用。因此，青年運動不要過量，以免影響睡眠，擾亂內分泌。此外，加強營養是身體長高的一個重要組成部分，加強鍛煉，要及時和充分補充造骨元素，包括膠質和無機鹽。
平常會聽到一些媽媽說自己寶寶一日三餐都吃得好，但是去醫院檢查居然發現還是寶寶得營養性貧血。這究竟是怎么回事兒呢？我們來聽聽專家怎么說。

小兒貧血有多種，本文僅就其中小兒貧血中最常見、最普通的一種類型——營養性缺鐵性貧血作一介紹。
營養性缺鐵性貧血顧名思義就是由於體內鐵缺乏，導致血紅蛋白合成減少，引起低血色素性貧血，這是嬰幼兒時期最常見的一種貧血。
一、原因
1、小兒體內先天貯鐵不足：胎兒從母體獲得的鐵以妊娠最後三個月最多，故早產、雙胎或多胎、胎兒失血和孕母嚴重缺鐵等均可使胎兒儲鐵減少。
2、生長發育因素：嬰兒期生長發育較快，隨體重增長血容量相應增加，嬰兒至一歲時體重增至初生時的3倍，早產兒可增至5-6倍，如不及時添加含鐵豐富的食物，則易致缺鐵。
3、鐵攝人量不足：這是缺鐵性貧血的主要原因。人奶、牛奶和穀物中含鐵量均低，不足嬰兒發育所需，如單用奶類喂養又不及時添加含鐵較多的輔食，則易發生缺鐵性貧血。
4、鐵的吸收障礙：食物搭配不合理可影響鐵的吸收。另外長期腹瀉、消化道畸形、腸吸收不良等引起鐵的吸收障礙時導致缺鐵性貧血。
5、鐵的丟失過多：食物過敏、腸息肉、美克爾憩室、鉤蟲病等都可引起腸道失血。失血1ml就相當於失鐵0.5mg，長期小量失血都是發生缺鐵性貧血的重要原因。另外長期反複患感染性疾病，可因消耗增多而引起貧血。
二、營養性缺鐵性貧血的臨床表現
任何年齡均可發病，以6個月至2歲最多見。
一般有皮膚、黏膜逐漸蒼白或蒼黃，以口唇、口腔黏膜及甲床最為明顯，食欲不佳、活動耐力差；稍大些的孩子可訴頭暈、眼前發黑、耳鳴、注意力不集中、不愛活動。重的可出現反甲，口腔黏膜及肛門發炎，異食癖，呼吸、脈率加快等。
三、診斷：
典型的貧血診斷並不難，可以化驗個血常規，看看血紅蛋白和紅細胞形態即可，世界衛生組織規定的貧血標准：
1、新生兒，如果血紅蛋白低於145克/升，就屬於貧血；
2、6個月~6歲的孩子，如果血紅蛋白低於110克/升，就屬於貧血；
3、6歲~14歲的孩子，血紅蛋白如果低於120克/升，就屬於貧血。
如臨床表現不典型時可試用鐵劑治療，如給藥後網織紅細胞升高、貧血改善，則有助於診斷。必要時可做骨髓檢查（包括鐵粒幼紅細胞和含鐵血黃素普魯氏藍染色檢查），以及血清鐵含量，血清鐵結合力等鐵代謝檢查。診斷明確貧血後還應進一步找出引起貧血的原因，以便對因治療。

Long Johns are a "thermal device" in cold weather. Before the winter, a lot of people start to dig it out of the closet, especially the elderly in the cold, the time of wearing long Johns is a long time. In the eyes of young people, long Johns are a "fashion enemy", and some people don't even wear them even one winter. Old people always say: "do not wear long Johns, later will have arthritis."
In fact, the term "arthritis" and "rheumatism" are often referred to as osteoarthritis, and most of the inflammation is caused by the joint reaching its lifespan. Some arthritis is caused by external trauma or disorders of the body's immune system, such as female menopause. As a result, arthritis has no direct link to long Johns. However, with the increase of high protein intake such as meat in the national diet, the overall resistance to cold will be improved, and it can be different for different people. However, people with osteoarthritis, menstruation, pregnant women and the cold must wear long Johns before they get cold The best way to reduce labour in refilling ! They have a small table top design and come with a year’s warranty. So, do some work with this machine! .
The fall pants material in the market is varied, also the more the more thin, often let a person pick up the eye. Some people worry that after sweating, the long Johns will become damp, and the skin will not be comfortable, and will cause skin diseases such as red rash. In this respect, pure cotton autumn pants air permeability is better, it is consumer's first choice. Clinically, we rarely see patients who are suffering from skin problems due to wearing cotton long Johns. Long Johns with cashmere ingredients are the highest, and are popular among middle-aged and elderly people. However, it is important to note that people who are allergic to wool are not fit to wear long Johns with cashmere ingredients. Some polyester and other chemical fiber components of the long autumn trousers, are "electrostatic professional households", the autumn and winter season humidity is small, when wearing this autumn trousers, always can hear the sound of the split. You'd better put on a moisturizer before you wear polyester. In addition, polyester materials may irritate the skin, especially those who are dry, itchy or allergic, and children with delicate skin are better off not wearing them. In addition, many women believe that tights are both warm and slim. But such long Johns are tightly wrapped in the body, causing the blood to not circulate, the body not only can not warm, but will be colder. Severe cases can lead to frostbite, cold lipitis and other problems. Furthermore, too tight leggings may increase local temperature, and the risk of gynecological infection increases. It is recommended that women choose the long Johns to remain loose and elastic.
