The pH of sweat can vary depending on the rate of sweating. At low sweat rates, sweat is typically acidic with a pH range of 3.5-6.0. However, at higher sweat rates, sweat becomes slightly alkaline, with a pH range of 7.0-8.5. This difference is likely due to the increased concentration of lactate produced by eccrine sweat glands during intense sweating.
The average pH of sweat is considered to be slightly acidic, with a mean pH of 6.3. This means that sweat is generally more acidic than blood, which has a pH of around 7.4.
Sweat analysis is becoming increasingly important for health monitoring and disease diagnosis. Wearable devices that can measure sweat pH and other biomarkers are being developed to provide real-time insights into an individual's health status.
