Building Your Weekly Protocol
TempRx Series | Part 12 of 12 You’ve made it through the science. Heat shock proteins. Cold shock proteins. Brown fat activation. BDNF. Cardiovascular conditioning. The Søberg protocol. Contrast therapy. Finnish mortality data. Neurochemical cascades. Now comes the question that actually matters: what do you do with all of this? Knowledge without application is just…

Contrast Therapy — Hot + Cold Together
TempRx Series | Part 11 of 12 So far, we’ve treated heat and cold as separate interventions. Sauna for cellular repair and cardiovascular health. Cold for neurochemical activation and metabolic boost. But what if you did both? Contrast therapy — alternating between hot and cold — isn’t a modern biohack. It’s ancient practice. Roman baths…

BDNF & Mental Clarity — Cold for Your Brain
TempRx Series | Part 10 of 12 We’ve talked about cold shock proteins. We’ve covered the norepinephrine spike. We’ve explored brown fat activation. But there’s another reason to embrace cold that doesn’t get enough attention: what it does for your brain. Cold exposure doesn’t just wake you up in the moment. It triggers changes in…

Cardio Load & Heart Health — Heat as Exercise
TempRx Series | Part 9 of 12 Here’s something that surprises people: sitting in a hot room can train your cardiovascular system. Not as a replacement for exercise. But as a genuine physiological stimulus that makes your heart work, your blood vessels adapt, and your cardiovascular risk factors improve. When Finnish researchers found that frequent…

Cold Showers vs. Cold Plunge — What’s the Real Difference?
TempRx Series | Part 8 of 12 You’ve heard the cold exposure advice. You understand the benefits. You’re ready to start. Then comes the practical question: do I really need a cold plunge? Or can I just turn my shower to cold? The internet is divided. Biohackers insist you need a dedicated tub at precisely…

Steam Rooms & Hot Tubs — Do They Count?

Brown Fat Activation — Cold as a Metabolic Tool
TempRx Series | Part 6 of 12 You have two types of fat. One stores energy. The other burns it. Most people only know about the first kind — white adipose tissue, the stuff you’re trying to lose, the insulation that accumulates around your midsection and thighs. White fat is a storage depot. Its job…

Finnish Sauna — The Gold Standard
TempRx Series | Part 5 of 12 If you want to understand heat therapy, you go to Finland. Not because the Finns invented the sauna — humans have used heat for millennia. But because Finland turned sauna use into a population-wide natural experiment, then let researchers study it for decades. The results are hard to…

The Søberg Protocol — 11 Minutes That Change Everything
TempRx Series | Part 4 of 12 Everyone wants to know the minimum effective dose. How little can I do and still get the benefits? For cold exposure, we actually have an answer. And it comes from Dr. Susanna Søberg, a Danish researcher who analyzed dozens of cold exposure studies to find the threshold where…

Cold Shock Proteins — The Other Side of the Coin
TempRx Series | Part 3 of 12 If heat shock proteins are the repair crew, cold shock proteins are the rapid response team. Different trigger. Different mechanism. Equally powerful. While heat stress tells your body to hunker down and fix what’s broken, cold stress tells your body to wake up, pay attention, and prepare for…
