Sweat Gland Density and Composition
- Sweat glands are dense especially on fingertips and forehead, producing sweat used beyond cooling.
- Sweat's chemical makeup varies by rate and volume but generally is consistent across sweat-inducing stimuli.
Sweat Biomarkers Reflect Blood Levels
- Sweat contains biomarkers like creatinine and urea correlating well with blood levels.
- This correlation makes sweat a promising fluid for health monitoring.
Wearable Sweat Collection Advice
- Use soft, skin-adherent patches with microfluidic channels to collect sweat reliably.
