Dehydration: an underestimated physiological problem

Dehydration occurs when the loss of water and electrolytes exceeds the body's ability to maintain equilibrium.
their internal balance. Even moderate fluid losses can affect physical and cognitive performance, thermoregulation, and a person's safety.


In environments with high physical demands or exposure to heat, such as sports, industry, or certain clinical contexts, these effects are amplified and increase the risk of fatigue, cramps, heat stroke, and accidents.

Why sweat is key

Sweating is the body's primary mechanism for dissipating heat.
In addition to water, it contains essential electrolytes such as sodium, potassium, and chloride, the loss of which is directly related to the onset of fatigue, cramps, and decreased performance.

Scientific evidence shows that the sweating rates and the electrolyte concentrations vary greatly between individuals and depending on environmental conditions, which makes generic hydration recommendations ineffective.

Do you want to improve thermal risk prevention in your company?

Traditionally, hydration has been managed using indirect or subjective methods such as body weight, urine color, or standard intake recommendations. These approaches do not account for individual variability and do not allow for effective prevention.

Although sweat sensors have emerged in recent years, many solutions are limited to displaying data without interpretation, lack sufficient scientific validation, or are not scalable to workplaces and clinical environments.

From measurement to an action plan

Sweanty integrates two key elements to transform physiological data into practical decisions

The SweaTracker: the smart patch

The SweaTracker is a smart, portable, and non-invasive patch that adheres to the skin using a medical-grade adhesive.


During the activity, it collects and analyzes sweat, measuring the total concentration of electrolytes.


Its technology is based on a patented paper battery system that allows for the measurement of sweat conductivity with a minimal amount of sample, in a robust, reproducible and low-cost manner.

Digital platform based on artificial intelligence

Sweanty's true value lies in its digital platform. Unlike other systems, it doesn't just display data, but interprets it using predictive models.

The platform integrates:

Based on this information, the platform generates personalized and predictive hydration plans, indicating what to drink, how much, and when.

Scientific validation and safety

SweaTracker technology has been developed and validated in collaboration with leading research centers and hospitals. It has demonstrated high accuracy in various studies and has CE marking, allowing its sale throughout the European Union.

This scientific validation ensures that the recommendations are based on reliable data and applicable to real-world contexts.

Why is prevention key?

Science shows that by the time the first symptoms of dehydration appear, the body is already in a state of imbalance that is difficult to reverse during activity. Therefore, hydration should be managed preventively, not reactively.

Sweanty allows you to anticipate risk and act before problems arise.
