Pre-Cooling Before a Race: What the Science Says
Pre-cooling before a race means lowering your body's heat before the effort begins, so you start with more headroom before heat limits yo...
JOURNAL
THE THINKING BEHIND THE TOOL.
Notes on heat, recovery, palm cooling, and the moment between efforts. Long-form context for what we are building and the science behind it.
HYROX Recovery Between Stations: How Heat Builds and How to Manage It
In HYROX, recovery between stations is short by design, and heat is one reason the back half feels heavier than the front. Core temperatu...
Why Do You Get Weaker Every Set?
Why do you get weaker every set? Part of it is normal fatigue, but heat is often the hidden limiter. As you work, your core temperature r...
Does Palm Cooling Work? An Honest Look at the Evidence
Does palm cooling work? In short, yes, as a way to move heat out of the body during rest, because the palm is one of the skin's most effi...
Rest & Recovery
Between efforts
The 90 seconds between sets is where the next set is decided. Why physiology carries across rest and most training spreadsheets miss it.
Rest & Recovery
Why Nobody Manages Temperature During Training
Modern athletes track nearly everything. Heart rate, sleep, hydration, power, pace. Yet temperature remains one of the least managed vari...
Palm Cooling
Newton, athletes, and the cooling gradient
The first thirty seconds of rest matter most. Why Newton's Law of Cooling explains when palm cooling works best between training efforts.
Palm Cooling
Why Palms and Face Exchange Heat More Efficiently
Not all areas of the body regulate heat equally. Peripheral regions like the palms and face contain specialized vascular structures that ...
Heat & Performance
Humans Became Endurance Predators Through Heat Regulation
Humans evolved to sustain effort in heat longer than most animals. Temperature regulation has always been tied to performance.
Heat & Performance
Singapore and the productive day
In 1999 Lee Kuan Yew named air conditioning the most important invention. Why temperature is a productivity variable that shaped economies.
Heat & Performance
Why Performance Drops Before You Feel Tired
Athletes often assume performance drops when fitness runs out. In many cases, the body begins reducing output earlier, as thermal strain ...
Heat & Performance
Why Temperature Shapes Performance
Temperature does not only affect comfort. It affects output, cognition, recovery and repeatability. That applies to economies and to athl...
