Foods rich in senolytic polyphenols—especially fisetin and quercetin—may help the body eliminate senescent “zombie” cells by reducing their SASP-driven inflammatory signaling and supporting immune clearance. Here’s what cellular senescence is doing to muscle, heart, and metabolic health—and the specific nutrient-dense foods that may help you “clean house.” “We used to think aging was a passive ...

In men, diet is rarely a major driver of high estrogen: most foods labeled “high in estrogen” contain phytoestrogens that only weakly activate estrogen receptors, while most estradiol is made inside the body when aromatase converts testosterone into estradiol in tissues such as body fat. If your estrogen-to-testosterone balance is off, here’s what the research ...

Here’s how this short 6–12 month “hyper-responsive” window ...

Sex and ejaculation can cause a short-lived testosterone rise of about 2 ng/mL, but levels typically return to baseline within 10–20 minutes, so it doesn’t meaningfully increase long-term testosterone. The bigger picture is a bidirectional feedback loop—testosterone drives libido, while arousal triggers a brief neuroendocrine surge—and why overall health often explains the “high T” sex-life ...

For most men, the better default is sauna after training because pre-workout heat stress increases core temperature and heart rate (via vasodilation), which can sap energy and reduce peak performance. Here’s how to time sauna for recovery and cardiovascular benefits — including when a short pre-session makes sense and how long to stay without overdoing ...
