O "drama" das esponjas da louça

Aparentemente mesmo fervendo não se resolve completamente o problema. A solução proposta é trocar todas as semanas:

""Sanitation by boiling or microwave treatment has been shown to significantly reduce the bacterial load of kitchen sponges and can, therefore, be regarded as a reasonable hygiene measure. However, our data showed that regularly sanitized sponges (as indicated by their users) did not contain less bacteria than uncleaned ones," the researcher reveal.

Not only did some of the bacteria survive the sanitation process, the researchers found that those "sanitation resistant" strains were able to quickly infest the sponge again and could even increase the number of disease-causing bacteria.

The researchers admit that further analyses are needed to substantiate their findings, but they still advise against DIY sanitation of kitchen sponges because it may actually do more harm than good. Their short-term advice is to simply replace kitchen sponges on a regular, weekly basis."

Deitem fora as esponjas de banho dizem dermatologistas

Nada de muito surpreendente mas que ainda não fizemos: Deitar fora as esponjas de banho (usadas para esfoliar, remover as células mortas da pele - o que alegadamente seria positivo). O problema é que estas células retidas na esponja podem ser o ambiente ideal (humidade e calor do banho) para que durante o dia todo o tipo de bactérias e bolores de desenvolvam (e nos afectem através de cortes na pele):

"Dermatology Institute, says they can do more harm than good.
That’s because the dead skin cells you scrub off get caught in the folds of netting.
He adds: “Then you put them in this environment in the shower that’s warm and moist and gross, and it’s a setup for bacteria, yeast and mold to grow in the puff.”
If you use them on newly shaved skin, the news is even worse.
The bacteria can then get into any tiny nicks and result in infections and bad skin."
