How is the pH of sweat helpful?

Sweat, which contains a wide range of biochemical markers, can tell us a lot about our health. Variations in sweat pH (i.e. acidity or alkalinity), for instance, can tell us whether our body is dehydrated and can aid the diagnosis of skin conditions such as dermatitis, acne and other skin infections.

Is human sweat acidic or basic?

In humans, sweat is hypoosmotic relative to plasma (i.e. less concentrated). Sweat is found at moderately acidic to neutral pH levels, typically between 4.5 and 7.0.

What is the alkalinity of sweat?

The pH of sweat was acid at low sweat rates (pH 3.5-6.0) and was slightly alkaline (pH 7.0-8.5) at high rates.

How do you measure the pH of sweat?

A pH sensitive dye incorporated into a fabric fluidic system is used to determine sweat pH. To detect the onset of sweat activity a sweat rate sensor is incorporated into a textile substrate. The sensors are integrated into a waistband and controlled by a central unit with wireless connectivity.

Is my sweat acidic or alkaline?
