近期，“南方人不要把手放屁股下取暖了”話題沖上熱搜第一。

A trending topic urging people in southern China to "stop warming their hands under their buttocks" has recently shot to the top of social media discussions, sparking both laughter and debate online.

評論區(qū)不少網(wǎng)友表示：雖然……但是真暖和??！

究竟有多暖和？有網(wǎng)友亮出了體驗“效果”：

本以為取暖方式會引發(fā)共鳴，結(jié)果，評論區(qū)畫風(fēng)走向卻是……

把手放屁股下取暖，除了行為不夠雅觀、容易留下印子之外，若長期采用此類姿勢，可能還會導(dǎo)致凍瘡（因手部受壓血液循環(huán)不暢）或肌肉酸痛。

Many commenters admit the method may look awkward but insist it is undeniably effective. However, it is warned that sitting on one's hands can restrict blood circulation and, if done frequently, may lead to chilblains, numbness, and muscle soreness.

除了屁股壓手（坐手保暖）之外，蒼蠅搓手（摩擦生熱）、原子吐息（哈氣暖手）、兩腿包夾（大腿夾手）……

這些“體內(nèi)自發(fā)熱”的保暖手段，南方人也是各個沒落下??！

Without widespread central heating, many people in southern China have developed creative "self-heating" techniques to cope with the damp winter chill — from sitting on their hands and rubbing their palms together to blowing warm air onto their fingers or tucking their hands between their thighs.

沒有暖氣的南方人，甚至連進(jìn)被窩也有詳細(xì)的保暖教程。

看到這里，不少北方人好奇：真有那么冷嗎？

其實，關(guān)于“南北方的冬天哪個更冷？”一直是冬季各大網(wǎng)友必爭的話題。

The discussion has once again reignited the long-running question: is winter in southern China really colder than in the north?

中國氣象數(shù)據(jù)指出：在同樣的大氣探測溫度下，南方要冷于北方，主要是體感溫度（apparent temperature）在作怪。

體感溫度是指人通過皮膚與外界環(huán)境接觸時在身體上或精神上所獲得的一種感受。因其他與氣候相關(guān)的狀況，使空氣和人體之間的熱對流受到影響，從而使人感覺的溫度與實際有差別，因此又名表觀氣溫或感覺溫度。

在影響體感溫度的因素中，風(fēng)力和相對濕度是重要的兩個氣象條件。

Meteorological data show that although northern China is generally colder in terms of actual temperature, southern winters often feel colder because of higher humidity. How cold people feel depends not only on temperature, but also on wind and humidity, which together determine "apparent temperature".

中國天氣網(wǎng)介紹，冬季時，南方相對濕度常常在70%以上，北方大部分時候風(fēng)力在2、3級左右。

當(dāng)南方相對濕度達(dá)到70%時，體感溫度就會從5℃降到2.6℃，北方則得刮起7級大風(fēng)才會讓體感溫度從5℃降到2.5℃。

也就是說，在同等氣溫條件下，南方更易遭受濕冷攻擊，而北方遭遇寒風(fēng)刺骨的幾率相對比較低。

但從實際氣溫上來看，冬季北方比南方整體要低。經(jīng)計算發(fā)現(xiàn)，只要氣溫相差超過5℃，相對濕度對體感溫度的影響就會弱化，低溫就會成為體感溫度之爭的關(guān)鍵。

In winter, humidity in many southern regions often exceeds 70 percent, while the north is usually drier but windier. At this humidity level, 5 C in the south can feel like 2.6 C, whereas the north would need strong winds to create a similar chill. This is why the south is often described as "wet cold" and the north as "dry cold". However, when the temperature difference exceeds about 5 C, actual low temperature becomes the dominant factor.

值得一提的是，體感溫度一定程度上也與個人對氣候的耐受性有關(guān)：大多數(shù)南方人會比較適應(yīng)濕冷，但一旦刮風(fēng)就會覺得很難受；而北方人可能會對大風(fēng)比較習(xí)慣，但到南方遇到濕冷天氣，就很不適應(yīng)。

Experts also note that individual tolerance varies: southerners are generally more accustomed to humid cold but find strong winds harder to bear, while northerners used to dry cold and wind often feel particularly uncomfortable in the damp southern winter.
