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。

How to Buy Bitcoin?

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.

That growth environment will include rising inflation and interest rates. Those upward shifts naturally accompany healthy growth periods as the demand for resources, products and services rise. Importantly, the Federal Reserve has laid out the rationale for not interfering with that natural growth transition.It's not exactly a fad, but there is a widespread willingness to pay up for a growth story. Classic fundamental analysis takes a back seat. Even negative earnings are ignored. In fact, positive earnings seem to be a limiting measure, producing the question, "Is that all you've got?" The preference is a vision of untold riches when the exciting story plays out as expected.
