Specific Gravity
Measure your urine's concentration to tell you if you are drinking enough water for your activity level.
What is Specific Gravity?
Specific gravity is a measure of the concentration of particles (i.e. desnsity) in a liquid compared to pure water.
Why does urine have Specific Gravity?
Urine is never just water. The kidneys filter the blood to remove waste products and excess nutrients while maintaining a precise balance of water in your body. Urine has a specific gravity because it contains metabolic wastes, electrolytes, and other Solutes.
Why track your Specific Gravity?
Tracking urine’s specific gravity is often used as a more precise "data-driven" alternative to just checking urine color. Urine concentration can tell you if you are drinking enough water for your activity level. High specific gravity after a workout might suggest significant fluid loss and a need for electrolyte-rich rehydration, not just plain water.
