冷水澡

冷水澡

有朋友問到這個報導的真實性,所以查了一下,

這是youtuber好葉在2017年的影片,不知道是被誰挖出來的。

他舉的例子是有實驗驗證沒錯,但我稍微找了找,發現了一些【解釋性錯誤】。

比如:

===

冷水澡治療憂鬱症的研究來看,這個研究放在這裡講就是有漏洞的,因為研究探討的方向是【極端的環境】對身體和頭腦的刺激,

These stressors include frequent acute physical activity as well as frequent (temporary) changes in body temperature, for example, occasional forced swimming in 【cold water or hunting in very hot weather. 】

然而研究並不是拿冷水澡和熱水澡來比,他們只是做了冷水的成果,而沒有做熱水的。

所以並不能說冷水澡有這個好處,而熱水澡沒有(熱水澡其實也算是極端環境,也會刺激血液循環,也會刺激頭腦)

Adapted Cold Shower as a Potential Treatment for Depression - PubMed
Depression is a debilitating mood disorder that is among the top causes of disability worldwide. It can be characterized by a set of somatic, emotional, and behavioral symptoms, one of which is a high risk of suicide. This work presents a hypothesis that depression may be caused by the convergence o…

而男性同胞最興奮(我覺得也是標題最吸睛的地方)的精子數量的研究,其實也是探討熱水【泡】澡的傷害,

而不是冷水澡的好處,研究是探討原本有在泡熱水澡( hot tubs, hot baths or whirlpool baths)的人,改成洗冷水澡之後精子的數量【比之前】多了491%,但這個應該叫做【回升】,而不是增加。

記得,這是【泡】熱水澡,泡著和用熱水沖,是兩種不一樣的情境(用鍋子煮雞蛋跟用流動的熱水煮雞蛋比,哪個雞蛋比較快熟?)。

所以這邊提到的冷水澡,頂多就是避免傷害而已,而用熱水沖澡,則不一定有降低精子數量的傷害。
