如何正确洗脚?专家揭示科学频率与方法

脚部聚集着大量细菌,但每个人的清洗次数不停。有些人会天天洗脚,有些人则在洗澡时顺便冲洗双脚。人们究竟应该如何清洗双脚,才能在保持卫生的同时,又不过度伤害皮肤保护层?

英国广播公司(BBC)报道,英国国家医疗保险(NHS)和美国疾病控制与预防中心(CDC)都建议人们应每天用肥皂和水清洗双脚,主要目的是防止产生异味。研究显示,定期清洗脚部可显著减少细菌数量,进而降低异味和感染的风险。

据了解,脚掌皮肤每平方厘米就有约有600个汗腺,是人体其他部位的数倍。尽管汗液本身无味,但汗腺富含盐分、葡萄糖、维生素和氨基酸,为细菌提供了理想的“营养库”。比如,葡萄球菌会把汗液中的一些成分转变成有气味的物质,导致脚臭,其中一种叫异戊酸的物质味道则尤为明显。所以,脚部皮肤不仅是细菌的栖息地,也为多种真菌提供肥沃的“温床”。

勤于清洁脚部不仅有助于减少异味,还能预防多种足部问题。由于脚趾间的狭窄环境极易滋生微生物,若不保持干净干燥,可能引发脚癣(俗称“香港脚”),通常表现为瘙痒、皮肤干裂等症状。若真菌感染得不到及时处理,还可能进一步扩散。此外,细菌感染如葡萄球菌感染,也可能通过皮肤小裂口进入血液,导致更严重的感染甚至化脓性疖肿。

对于糖尿病患者,维持良好的脚部卫生尤为重要。研究表明,糖尿病患者的脚部皮肤携带更多致病菌,感染风险更高。此外,糖尿病患者免疫功能较弱,伤口愈合慢,若不及时清洁和检查脚部,可能导致溃疡甚至截肢。

Export WhatsApp stickers to Telegram on Android

From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.

Newly uncovered hack campaign in Telegram

The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.
