夏阳炽烤,气温骤升,中暑之患随之而生。非惟不适,实关乎安危。中暑之祸,可悄然而至,尤甚于童稚与父母,奔波于夏日之乐也。
2026-05-24 · via The Hindu: Latest News today from India and the World, Breaking news, Top Headlines and Trending News Videos.

身热过甚,不能自凉,此乃中暑之症,不可不知也。

亦读 | 热浪果真为热浪乎?

中暑者何?

身热过甚,致凉系统失灵,是为中暑。与热衰竭(较轻,常多汗而晕眩)异,中暑乃危急之症,身之温控全然失效。其状若身内之温计骤乱,或伤及要脏,若不及时疗治,甚至致命。

症状

欲识中暑之兆,当察其警候。童稚当知其状,如肤热而燥,神昏,脉速,眩冒,呕恶。此乃身内调温之机,为热所困,不能自适。身不能因汗而凉,遂致脱水,而身核之温愈高。身既不能御热,遂发种种生理之应,昏聩脉亢是也。

润泽身躯,着轻衣,用日晒之药,乃避炎之常法也。

日之盛,在辰巳至未申之间,故宜谋户外之事于晨昏清凉之时。

专家之谏

吾与陈教授、博士、P·萨兰纳库马尔博士、MD、儿科DNB博士、哲学博士语。斯人于斯道已十七载,其于热射之预防与治理,见地至珍,尤值夏日炎阳炙烤,童稚最易感之季。

童子喜游于外,然暑气之下,易忘饮水,遂致脱水。脱水者,体失水也。萨瓦兰库马博士戒曰:脱水可致:

  • 渴甚而口燥
  • 头痛而恶心
  • 肌肉痉挛与皮疹
  • 呼吸之难(间或有之)

初患热疾,首当移儿于阴凉处,饮凉水以降体温。萨兰纳库马博士 医学博士,儿科学博士,哲学博士

寒凉之食与夏时更易致脱水之患

萨兰纳库马博士指出,虽儿辈或渴求寒饮冰酪以解燥渴,然此甘甜之食实难济其脱水之苦。其强调此等选择,兼夏时饮食之变(如多食外食),可致:

上呼吸道之疾: 寒饮可激喉,或增咳嗽、感冒乃至乳蛾之患。

胃疾: 乍食外膳或啖瓜过多,童子或致腹痛泄泻,益增消渴之虞。

童子何以易中暑

“身形稚子,较之成人,其表面积与体重之比尤大。盖因其表面积甚广,且肤质柔薄,故较成人,易致疲乏,多汗,蒸发过甚。”

表面积与体重之比愈高

较之成人,童子之体,其肤相对其形,暴露者广。此较广之表面积,使其速热而缓失其热。

研究表明,童子较之成人,汗如雨下者少,故散热之能亦弱,是以暑热之患易加焉。加之其身方长,散热之机较成人犹疏。此数者相合,童子易罹暑疾,是故谨防热射,护其安康于炎阳之下,实为要务。

为之

萨兰纳库马博士详述若疑儿辈中暑,当行之要术:

  • 使儿凉之:移置阴处或空调之所。予凉饮(勿过寒),令其啜之。
  • 汗蒸法:可借此法以更降其身热。此需以凉湿之巾帛覆儿肤,而轻扇之。裆、颈、腋置冰囊亦有益焉。
  • 立寻医助:速携稚子就医,或赴急诊室。

须谨察:观稚子神志,若寤而应,可续予饮液。

滋養為要

雖無普適之飲水法,然有大概之準則:

五歲以下兒童:日飲液體八百二十毫升至一公升。

十三歲以下兒童:日飲液體約三公升。

日间宜供饮,非独渴时也。水为上品,若果浆乳亦可行。然电解质之衡,尤当留意,可择含钠之物以佐之。

“曩者,热中诸症,惟夏日发之。今则四时皆有。此或天时之变也。近有热竭之症亦渐增。”曰萨兰那库马博士

事闻
君岂闻乎?

常人于酷暑之中,每时或可失汗盈升。

大地之最热,何如?

答:134°F(56.7°C),在加利福尼亚之死谷。

剃发可使人凉否?

答:非也,发实可御日之热。

西瓜之力

西瓜含九十以上之水,乃消暑解渴之佳品也。

禽兽亦然

纵使康健之畜,如犬,若置之户外,值炎日炙烤,亦不免中暑。
