Believe it or not, our sweat can tell us a lot about what’s going on inside our body. According to Wikipedia, “Perspiration, also known as sweating, is the production of fluids secreted by the sweat glands in the skin of mammals. Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. The eccrine sweat glands are distributed over much of the body.” But why do we sweat? Here is a quick video to provide the basics on Thermoregulation.   With health wearables, the natural progression of sensors has expanded to sweat sensors. What can we measure if we had sweat? Apparently a lot. Researchers at North Carolina University have developed a wearable device that uses sweat from a body to measure performance. The prototype device is like a watch you wear on your wrist. It can measure glucose/lactose, PH levels and temperature. This type of device would be beneficial to athletes and military use.   To read more about this, check this out:
