My face, head, arms and hands are more sensitive to changes in temperature than the rest of the body, which tells my brain that covering them up does more to prevent heat loss. Sensations of heat loss versus real heat loss We can use these physical principles to stay cool-and control them to stay warm, if we use the right layering strategy.

If we’re wet from sweat and don’t harness this radiation leaving our body, our skin will also actively dump heat through conduction and convection. Tossing on a puffy, we trap this radiation. While the body is at rest, the body’s primary method for discharging heat is radiation. The speed of this fluid with respect your body determines the rate the heat transfer known as wind chill. Convection is heat transfer between the surface and a fluid and, in our case, the air. It’s Newton's 2nd law of thermodynamics.īut there’s also convective heat transfer. In this case, your sweat-soaked base layers in contact with your skin or you bum on the rock will transfer heat-always in the direction from hot to cold. Alternatively, conduction is the process of losing heat through physical contact with another object, like heat traveling through a copper wire. The blood underneath the skin is cooled by means of a thermo-reaction and heat exchange-sweat evaporates, which cools your extremities, skin, and the blood under your skin. As we are active, we begin to produce heat. The opposite occurs when warm blood is needed to flow from the limbs to heat the core. Blood acts as a coolant, exchanging heat-hot blood travels away from the core toward the extremities. Inversely, those same parts need to be warm enough and maintain a core temperature of 98.6F. The body is mostly concerned with keeping the brain and internal organs cool to run smoothly. Understanding a bit of the science behind how our bodies regulate temperature will help you pick the best system of clothing to work with it when you’re working hard in the outdoors. And we manage our heat gain and loss by a built-in processes called thermoregulation. I’ve also added the personal selections I’ve come to love as I’ve narrowed my focus to what simply works.ĭuring exercise, the human body can produce enough energy to power the lights in your home. Are you a high-intensity winter athlete? Here’s a deeper look at the OR line and how they might work best for you, and why.

We need not just the right tools for the job, but we need them to be perfect. High-intensity athletes are intense people.
