Soak Textile Spray Detects Dehydration In Sweat And Changes Color
FAST COMPANY - Aug 17 - If you're healthy, your clothes will look blue, but the coating turns yellow, then brown, if the levels of acids in your sweat is too high, whether from dehydration or a bad diet. The spray can be squirted on before you work out, and then washes out in the wash.
