No inverno as nossas veias sofrem a vasoconstrição. O que é isso? Ela diminui, encolhe. Se eu estiver com meu pé descoberto, por exemplo, só com uma blusa e uma calça, o meu coração vai trabalhar dobrado até meu pé ficar quente. Quando ele faz isso, aumenta em torno de 30% o risco de um infarto e, em média, 20% o risco para um AVC, que é um derrame. Ou seja, como é que eu ajudo meu coração? Mantendo os meus pés aquecidos, o meu corpo inteiro aquecido, com blusa, com calças, com roupas quentes, para que ele trabalhe menos. Isso é muito importante, em especial para os idosos, hipertensos, diabéticos, fumantes. Eu diria que todos nós precisamos ter esse cuidado porque no inverno nós vamos ver esse aumento acontecer gritantemente, porém o uso de uma meia e manter tudo isso quentinho fará toda a diferença na vida de todos nós. Então, essa é a minha orientação. Cuidem não só do corpo, mas aqueçam os pés."

Bed bug bites can develop into red, itchy and swollen welts, quickly causing skin irritation at the bite site.

Publisher’s rating: The claim that bed bug bites can develop into red, itchy, and swollen welts, quickly causing skin irritation at the bite site, is accurate. Bed bugs feed on human blood. Their bites are typically painless initially but can develop into red, swollen welts within a few hours or days. These welts are often intensely itchy and can cause significant skin irritation. The symptoms described are well-documented in medical literature, confirming the accuracy of this claim.

Bill Gates bringt «Madenmilch» auf den Markt, um die Welt zu retten.

Publisher’s rating: Nein. Der Microsoft-Gründer hat nie etwas mit der «Entomilk» zu tun gehabt. Das Unternehmen dahinter, Gourmet Grubb, scheint ebenfalls aus dem Geschäft zu sein.

The review reports that the Bill & Melinda Gates Foundation called the claim false and that its funding records showed no support for Entomilk or Gourmet Grubb. Entomilk did once exist, but the review says Bill Gates was mentioned on its archived website in a broader discussion of insect-based food startups, not as an investor.

Gel manicures leads of skin cancer

Publisher’s rating: While research suggests that radiation emitted by UV-nail polish dryers can damage DNA, there are no conclusive findings yet about it causing skin cancer in humans.

Related reporting describes a possible increased risk, not proof that gel manicures cause skin cancer. It says UV rays from curing lamps have been linked to increased risk, and a dermatologist cited in another report warns of higher risk in exposed areas.

Les mammographies sont interdites en Suisse.

Publisher’s rating: La mammographie n'est pas interdite en Suisse. Dans certains cantons, un programme invite les femmes de 50 ans et plus à passer un examen tous les deux ans, sur une base volontaire. Les experts estiment que l'exposition aux rayonnements est faible et que les avantages surpassent les risques.

The review says mammography is not banned in Switzerland. It reports that some cantons offer voluntary screening every two years to women aged 50 and older, and that experts consider the radiation exposure low relative to the benefits.
