“…The losses were more in line with those reported in men participating in moderate exercise (8,9) at room temperature. The difference may be partly attributable to environment, because calcium losses in sweat increase with heat (9,21). Calcium losses through sweat increased from 111 mgId j1 at 21-C to 201 mgId j1 at 37.8-C, as estimated by arm-bag collections during 7.5-h periods that included 100 min of exercise (9).…”

“…The effect of exercise on dermal calcium loss in our study was less than expected on the basis of the much greater losses (9 100 mg per session) reported in men participating in rigorous exercise-that is, professional basketball practice and firefighting training (12,18). The losses were more in line with those reported in men participating in moderate exercise (8,9) at room temperature. The difference may be partly attributable to environment, because calcium losses in sweat increase with heat (9,21).…”

“…Sweat calcium losses averaged 8.1 mgIh j1 at 21-C. In a second experiment, three men participating in moderate exercise for 30 min at 23.9-C lost an average of 3 mgIh j1 calcium in sweat (9). Whole-body dermal calcium losses during 40 min of intense exercise in 16 young men ranged from 18 to 31 mg (8).…”

“…Johnston and Hagan [14] were the first to report that iron (Fe) ions were present in sweat. After this important finding, the ions of the following trace elements were measured in sweat: Ca, Fe, copper (Cu), zinc (Zn), manganese (Mn), chromium (Cr), cobalt (Co), molybdenum (Mo), nickel (Ni), iodine (I), strontium (Sr), titanium (Ti), aluminum (Al), cadmium (Cd) and Mg [15,16,17,18]. One study collected the sweat from 10 healthy male adults aged 22-26 years exposed to a sauna (60°C, 30 min) and measured the concentrations of the ions of Na, chlorine (Cl), K, Ca, phosphorus (P), Mg, Zn, Cu, Fe, Ni, Cr and Mn in the sweat.…”

The skin excretes substances primarily through sweat glands. Several conditions have been demonstrated to be associated with diminished sweating. However, few studies have concentrated on the metabolism and excretion of sweat. This review focuses on the relationship between temperature and the thermoregulatory efficacy of sweat, and then discusses the excretion of sweat, which includes the metabolism of water, minerals, proteins, vitamins as well as toxic substances. The potential role of sweat secretion in hormone homeostasis and the effects on the defense system of the skin are also clarified.

Nutrients play critical roles in maintaining core physiological functions and in preventing diseases. Technologies for delivering these nutrients and for monitoring their concentrations can help to ensure proper nutritional balance. Eccrine sweat is a potentially attractive class of biofluid for monitoring purposes due to the ability to capture sweat easily and noninvasively from nearly any region of the body using skin‐integrated microfluidic technologies. Here, a miniaturized system of this type is presented that allows simple, rapid colorimetric assessments of the concentrations of multiple essential nutrients in sweat, simultaneously and without any supporting electronics – vitamin C, calcium, zinc, and iron. A transdermal patch integrated directly with the microfluidics supports passive, sustained delivery of these species to the body throughout a period of wear. Comparisons of measurement results to those from traditional lab analysis methods demonstrate the accuracy and reliability of this platform. On‐body tests with human subjects reveal correlations between the time dynamics of concentrations of these nutrients in sweat and those of the corresponding concentrations in blood. Studies conducted before and after consuming certain foods and beverages highlight practical capabilities in monitoring nutritional balance, with strong potential to serve as a basis for guiding personalized dietary choices.
