Found solution for LSU cramping/dehydration problem?

"The sensors turn the data into an electrical signal and transmit it wirelessly to a mobile app for monitoring. Dehydration, which occurs when you have electrolyte imbalances from losing too much water from the body, can lead to nausea, lethargy and fluid retention, conditions that could be dangerous for fighter pilots as well as first responders and elite athletes. By monitoring the real-time measurements, for example, fire chiefs can better decide when to swap in another firefighter and prevent injury."
