Analyzing your sweat informs you about your individual fluid and electrolyte needs. There is massive variability in sweat rate and sweat composition from one individual to another - and even for one individual from one day to the next. Analyzing your sweat across a range of environmental conditions, sport types, and workout intensity levels, you can create a personal sweat profile that provides a bespoke strategy for fluid and electrolyte replenishment that is tailored to your particular needs on a given day. This allows you to combat dehydration and optimize your performance.
