Your core temperature

  • When you exercise, your muscles produce heat. During physical activity, your body temperature can rise up to 3 degrees. To combat this, your body starts to sweat to cool down. Known as “evaporative cooling”, this process is your body’s natural mechanism to maintain a lower core temperature. Merino moves moisture as a vapor, before it even has a chance to turn to sweat, keeping you cooler.
  • Research shows that because of wool’s effective moisture management, you maintain a lower and more stable core body temperature when wearing wool next to skin instead of synthetics.

Your heart rate

  • When you exercise, your muscles produce heat, which in turn, heats your blood. As you begin to sweat, your body’s blood volume decreases, your blood pressure drops, and blood flow between your muscles and your skin is reduced.
  • Research shows that because of wool’s efficiency assisting your body’s natural cooling process, you can maintain a lower heart rate when wearing wool next to skin instead of synthetics.

Lactic acid build-up

  • When you exercise, your core body temperature rises as your blood works to deliver enough oxygen to your muscles. This triggers lactic acid production.
  • Lactic acid build-up results in fatigue, muscle pain, and even cramps. When you slow the rate at which your core body temperature increases, you also slow the rate at which lactic acid
 builds up.
  • Research has shown that wearing wool next to your skin is an effective way to limit rise in core body temperature during exercise, slowing the rate at which lactic acid builds up in your muscle.
