加護病房都用溫水洗手？洗手水溫會影響病菌數量嗎

今天看完病人在洗手的時候，發現水特別熱，想說，是不是加護病房的洗手水溫有特別意義呢？

這個問題最先想到的就是就是阿長，之後又去查了一下文獻，最後在問一下資深護理人員

結果最後的結果是..沒有特別意義

那為何會有熱水呢？

因為護士常常造洗手，天氣冷，洗冷水手不舒服，所以改用熱水

但是如果又太熱的水，手更容易乾燥，所以建議都用溫水。

不過的確有部分文獻說，溫的肥皂水或是含有滅菌成分的水可以幫助清潔更多細菌：

Hot water that is comfortable for washing hands is not hot enough to kill bacteria. Bacteria grows much faster at body temperature (37 C). However, warm, soapy water is more effective than cold, soapy water at removing the natural oils on your hands which hold soils and bacteria.

Laestadius JG, Dimberg L (April 2005). "Hot water for handwashing—where is the proof?". J. Occup. Environ. Med. 47 (4): 434–5.

Contrary to popular belief however, scientific studies have shown that using warm water has no effect on reducing the microbial load on hands.

You've probably been told that it's best to wash your hands in hot water because it helps to kill bacteria, but that is actually not the case. Adult skin can begin to scald at 120 degrees Fahrenheit (49 degrees Celsius), but studies have shown that hands washed using water up to that temperature still don't remove bacteria
