Your body is like a little furnace3. It puts out heat all the time. It comes from your body doing the work that keeps you alive4. When it puts out a lot more or a lot less heat than usual， it is trying to tell you theres a problem.

Not everyones “normal” body temperature is the same. Yours could be a whole degree different than someone elses.

A German doctor in the 19th century set the standard5 at 98.6 F， but more recent6 studies say the baseline7 for most people is closer to 98.2 F.

For an adult8， body temperature can be anywhere from 97 F to 99 F. Babies and children have a little higher range9： 97.9 F to 100.4 F.

Your temperature doesnt stay same all day， and it will be different in your lifetime， too. Some things that make your temperature move around during the day include10：

●How active you are

●What time of day it is

●Your age

●Your sex

●What youve eaten or drunk

●（If youre a woman） where you are in your menstrual cycle11

你的身體就像一個(gè)小火爐，一直在釋放熱量。熱量來(lái)自于你的身體，它維系著你的生命。當(dāng)它釋放的熱量比平常偏多或偏少時(shí)，就是告訴你身體有問(wèn)題了。

不是每個(gè)人的“正?！斌w溫都是一樣的。 你的“正?！斌w溫可能與別人有一整個(gè)度的差異。

在19世紀(jì)，一位德國(guó)醫(yī)生把體溫標(biāo)準(zhǔn)設(shè)定為華氏98.6度（37℃），但最近的研究表明，大多數(shù)人的基準(zhǔn)體溫接近華氏98.2度（約36.8℃）。

對(duì)于成年人來(lái)說(shuō)，體溫可能在97到99華氏度之間（36.1℃-37.2℃）。嬰兒和兒童的體溫范圍稍高一些：97.9到100.4華氏度（36.6℃—38℃）。

你的體溫不會(huì)整天不變，而且在你的一生中，體溫也會(huì)有所變化。導(dǎo)致你一天中體溫變化的因素包括：

●你的活躍狀態(tài)

●一天中的時(shí)間段

●你的年齡

●你的性別

●你吃了什么或喝了什么

●（如果你是女性）處于例假期間的什么階段
