Androgens (T, DHT) highly protective against the flu

A gem of a study that throws a wrench in one of medicine’s core dogmas – i.e. androgens have detrimental effects on the immune system and males have evolved to live with a trade-off between high androgen levels (and as such high fertility) and higher risk of severe viral episodes that can be even deadly. … Read more

Face masks (at best) ineffective against SARS-CoV-2 / COVID-19 and flu

A series of studies, some of them covering viruses other than SARS-CoV-2, yet the findings of all of them are the same – no statistically significant protective effect of face masks, and, in some cases, possibly increased rates of infection (see first study below). “…A total of 3030 participants were randomly assigned to … Read more

Adrenaline suppresses the immune system and promotes viral infections

The timing of this study just could not have been better considering the current coronavirus epidemic. The study below demonstrates that both adrenaline and noradrenaline suppressed the immune system and both increases vulnerability to viral infection as well as increasing mortality after the infection takes hold. Conversely, blocking the adrenergic receptors increased survival rates by … Read more

Suppressed immunity, not viruses (HPV), may be the cause of (skin) cancer

Recently, I posted some threads in regards to immunosuppression and cancer. Here are two that provide a good overview and tie together the immunosuppressive effects of PUFA, estrogen, and cortisol with the protective effects of vitamin A, E, D, progesterone, etc. PUFA are immunosuppressive, fasting and protein restriction (possibly) even more so Vitamin D may … Read more
