起底從古生物到現(xiàn)生：野駱駝化石揭示的沙漠環(huán)境演變史

上了年紀(jì)的人身體逐漸衰老，正確保養(yǎng)身體是關(guān)鍵，只有養(yǎng)生原則遵循，身體得到良好的調(diào)節(jié)，才能遠(yuǎn)離疾病困擾。很多人到了60歲之后身體走下坡路，但是在養(yǎng)生過程中沒有注意很多的細(xì)節(jié)，很難為健康加分，還可能在抵抗力薄弱，疾病出現(xiàn)之后影響正常生活，甚至縮短老年人的壽命。那么，養(yǎng)生的老年人哪些方面不可掉以輕心呢？

1、注意衛(wèi)生

要保持身體健康，生活中各種細(xì)節(jié)得注意，從衛(wèi)生這方面入手進(jìn)行調(diào)節(jié)，才能達(dá)到預(yù)防疾病的效果。上了年紀(jì)的人體質(zhì)下降，身體逐漸衰老，免疫系統(tǒng)無法正常發(fā)揮功能，此時(shí)就應(yīng)該講衛(wèi)生。

飯前便后勤洗手，身體的清潔工作做好，通過保持身體干凈，衛(wèi)生可以讓疾病遠(yuǎn)離。因?yàn)橹v衛(wèi)生可以防止身上附著著很多的細(xì)菌，病毒，通過這種方式讓疾病患病率下降。很多人不講衛(wèi)生，很容易滋生細(xì)菌后入侵身體引發(fā)疾病。

2、補(bǔ)充足夠營(yíng)養(yǎng)

老年人想要養(yǎng)護(hù)身體，平時(shí)應(yīng)該注意營(yíng)養(yǎng)物質(zhì)的補(bǔ)充。上了年紀(jì)的人身體老化速度加快，某些重要器官功能降低，吸收營(yíng)養(yǎng)物質(zhì)的速度緩慢，因此更需要重視營(yíng)養(yǎng)全面獲取。

上了年紀(jì)的人補(bǔ)充足夠的蛋白質(zhì)，維生素可以增強(qiáng)身體素質(zhì)，防止抵抗力薄弱讓疾病有機(jī)可乘。另外，年齡增長(zhǎng)鈣質(zhì)流失，可能會(huì)缺鈣引發(fā)骨質(zhì)疏松癥，如果可以多吃高鈣食物，滿足身體對(duì)鈣質(zhì)的需求，對(duì)骨骼有保護(hù)作用，才是養(yǎng)生，促進(jìn)健康的好方法。

3、水分獲取充足

要保持老年人身體健康，在養(yǎng)生的時(shí)候水分獲取量要充足，通過每天正確的飲水方式可以滿足水分需求，達(dá)到促進(jìn)血液循環(huán)，提高身體新陳代謝能力的目的。很多人經(jīng)常在口腔干燥，明顯口渴的時(shí)候才飲水，這種情況對(duì)身體健康不利。

口渴是身體已經(jīng)發(fā)出信號(hào)，說明水分明顯缺乏，應(yīng)該分多次少量飲水，每天的飲水量達(dá)到2000毫升左右，才能在機(jī)體水分需求滿足之后促進(jìn)健康，將體內(nèi)的有害物質(zhì)排泄出體外，達(dá)到良好的養(yǎng)生效果。

4、作息正確

老年人想要正確養(yǎng)生還應(yīng)該作息保持規(guī)律，每天都有充足的睡眠時(shí)間，疾病也可以遠(yuǎn)離。很多人長(zhǎng)時(shí)間作息不規(guī)律，沒有充足的睡眠時(shí)間來延緩機(jī)體衰老，促進(jìn)健康，久而久之疾病容易入侵。

而在保養(yǎng)身體的過程中老年人要注意睡眠質(zhì)量的提高，保持情緒的放松，睡前不要經(jīng)常運(yùn)動(dòng)，也不要過度吸煙喝酒，還要調(diào)整好睡眠環(huán)境，才能擁有高質(zhì)量的睡眠讓健康靠近。
