Injuries in the cold are more asterisk. Injuries in the cold are more asterisk. Injuries in the cold are more likely not because cold is dangerous in likely not because cold is dangerous in likely not because cold is dangerous in itself, but because cold requires us to itself, but because cold requires us to itself, but because cold requires us to be deliberate. It reveals where we've be deliberate. It reveals where we've be deliberate. It reveals where we've skipped steps. It reveals where the body skipped steps. It reveals where the body skipped steps. It reveals where the body isn't yet ready. And that's not a isn't yet ready. And that's not a isn't yet ready. And that's not a warning. It's a gift because it teaches warning. It's a gift because it teaches warning. It's a gift because it teaches us to be in dialogue with our us to be in dialogue with our us to be in dialogue with our physiology, to move not out of habit, physiology, to move not out of habit, physiology, to move not out of habit, but out of deep listening. Now heat but out of deep listening. Now heat but out of deep listening. Now heat tells a different story. It can feel tells a different story. It can feel tells a different story. It can feel like freedom. Muscles feel open, like freedom. Muscles feel open, like freedom. Muscles feel open, responsive. Movement flows, but there's responsive.

In the heat, we sometimes go too far. Overconfidence sometimes go too far. Overconfidence sometimes go too far. Overconfidence replaces caution. Endurance feels replaces caution. Endurance feels replaces caution. Endurance feels endless until it's not. Muscles may be endless until it's not. Muscles may be endless until it's not. Muscles may be more elastic, but they're also under more elastic, but they're also under more elastic, but they're also under greater physiological strain. greater physiological strain. greater physiological strain. Dehydration creeps in. Electrolyte Dehydration creeps in. Electrolyte Dehydration creeps in. Electrolyte imbalances start to interfere with nerve imbalances start to interfere with nerve imbalances start to interfere with nerve conduction. The body is doing more work

The body is doing more work than it feels like because heat lowers than it feels like because heat lowers than it feels like because heat lowers our perception of exertion while our perception of exertion while our perception of exertion while increasing our actual load. It's in this increasing our actual load. It's in this increasing our actual load. It's in this deceptive comfort that injury risk deceptive comfort that injury risk deceptive comfort that injury risk hides, not in the tightness of cold, but hides, not in the tightness of cold, but hides, not in the tightness of cold, but in the illusion of ease. The tissue in the illusion of ease. The tissue in the illusion of ease. The tissue might be more forgiving, but the system might be more forgiving, but the system might be more forgiving, but the system is under pressure. Heat increases is under pressure. Heat increases is under pressure. Heat increases metabolic demand, and the more demand metabolic demand, and the more demand metabolic demand, and the more demand you place on your muscles, the closer you place on your muscles, the closer you place on your muscles, the closer they move toward failure, especially if they move toward failure, especially if they move toward failure, especially if the nervous system is lagging behind in the nervous system is lagging behind in the nervous system is lagging behind in signaling fatigue. What's fascinating, signaling fatigue. What's fascinating, signaling fatigue. What's fascinating, though, is how both cold and heat though, is how both cold and heat though, is how both cold and heat illuminate different aspects of safety illuminate different aspects of safety illuminate different aspects of safety and injury. Not by creating risk, but by and injury. Not by creating risk, but by and injury. Not by creating risk, but by teaching us to respect context. There's teaching us to respect context. There's teaching us to respect context. There's no one sizefitsall approach to movement. no one sizefitsall approach to movement. no one sizefitsall approach to movement. A body warmed by heat is not the same as A body warmed by heat is not the same as A body warmed by heat is not the same as a body that's cold and cautious, and a body that's cold and cautious, and a body that's cold and cautious, and neither is better. What matters is the neither is better. What matters is the neither is better. What matters is the awareness we bring into the space. The awareness we bring into the space. The awareness we bring into the space. The truth is, most injuries don't come from
30:00truth is, most injuries don't come from truth is, most injuries don't come from big moments. They come from tiny gaps in big moments. They come from tiny gaps in big moments. They come from tiny gaps in awareness, an ankle turned when focus awareness, an ankle turned when focus awareness, an ankle turned when focus slipped, a back strained when tension slipped, a back strained when tension slipped, a back strained when tension was ignored, and those gaps widen when was ignored, and those gaps widen when was ignored, and those gaps widen when we disconnect from the present. Cold we disconnect from the present. Cold we disconnect from the present. Cold brings a forced stillness. Heat brings a brings a forced stillness. Heat brings a brings a forced stillness. Heat brings a deceptive freedom. And both are deceptive freedom. And both are deceptive freedom. And both are opportunities to return to presence. To opportunities to return to presence.

This is why recovery matters just as much as why recovery matters just as much as why recovery matters just as much as performance. Why regulation is as performance. Why regulation is as performance. Why regulation is as important as activation. If cold important as activation. If cold important as activation. If cold contracts and heat expands, then
31:00contracts and heat expands, then contracts and heat expands, then recovery asterisk integrates asterisk. recovery asterisk integrates asterisk. recovery asterisk integrates asterisk. It's what allows the nervous system to It's what allows the nervous system to It's what allows the nervous system to process challenge and rebuild trust in process challenge and rebuild trust in process challenge and rebuild trust in the body. And without that trust, even the body. And without that trust, even the body. And without that trust, even the strongest muscles become fragile. the strongest muscles become fragile. the strongest muscles become fragile. That's the paradox. Strength without That's the paradox. Strength without That's the paradox. Strength without awareness is brittle. Flexibility awareness is brittle. Flexibility awareness is brittle. Flexibility without boundaries is chaotic. Injury without boundaries is chaotic. Injury without boundaries is chaotic. Injury happens when those extremes go happens when those extremes go happens when those extremes go unbalanced. But when we engage with cold unbalanced. But when we engage with cold unbalanced. But when we engage with cold and heat, as asterisk teachers asterisk, and heat, as asterisk teachers asterisk, and heat, as asterisk teachers asterisk, not just tools, the body begins to not just tools, the body begins to not just tools, the body begins to rewire its own intuition. We don't just rewire its own intuition. We don't just rewire its own intuition. We don't just reduce injury. We increase asterisk reduce injury. We increase asterisk reduce injury. We increase asterisk intelligence asterisk sematic intelligence asterisk sematic intelligence asterisk sematic intelligence. The kind that doesn't rely intelligence. The kind that doesn't rely intelligence. The kind that doesn't rely on data or devices, but on deep lived in on data or devices, but on deep lived in on data or devices, but on deep lived in understanding. That's what makes injury understanding. That's what makes injury understanding. That's what makes injury prevention so profound. It's not just prevention so profound. It's not just prevention so profound. It's not just about avoiding harm. It's about about avoiding harm. It's about about avoiding harm. It's about embodying wisdom, learning when to move embodying wisdom, learning when to move embodying wisdom, learning when to move forward and when to slow down, when to
32:00forward and when to slow down, when to forward and when to slow down, when to push and when to listen. And in that push and when to listen. And in that push and when to listen. And in that balance, we don't just protect balance, we don't just protect balance, we don't just protect ourselves, we elevate how we show up in ourselves, we elevate how we show up in ourselves, we elevate how we show up in the world. So whether you're stepping the world. So whether you're stepping the world. So whether you're stepping into an ice bath or finishing a session into an ice bath or finishing a session into an ice bath or finishing a session under the summer sun, ask yourself not under the summer sun, ask yourself not under the summer sun, ask yourself not just what did my muscles do today, but just what did my muscles do today, but just what did my muscles do today, but what did they learn? Because the real what did they learn? Because the real what did they learn? Because the real measure of strength isn't what your body measure of strength isn't what your body measure of strength isn't what your body can endure, it's what it can asterisk can endure, it's what it can asterisk can endure, it's what it can asterisk understand asterisk and asterisk respond understand asterisk and asterisk respond understand asterisk and asterisk respond to asterisk with care. asterisk to asterisk with care. asterisk to asterisk with care. asterisk asterisk. In the end, the most asterisk. In the end, the most asterisk. In the end, the most injuryresistant body is not the injuryresistant body is not the injuryresistant body is not the strongest or the most flexible. It's the strongest or the most flexible.
