THE NAESIA APP
Your sweat. Understood.
Follow estimated losses while you train, review totals afterwards and compare sessions over time. These simulated screens show how the NAESIA app could work.

01 / LIVE WORKOUT
In the moment.
View local sodium concentration, estimated whole-body sweat rate and cumulative fluid and sodium losses as the workout progresses.
Move through a simulated session. Totals integrate losses over time; the current rate is a point-in-time estimate.
Current sodium loss rate: 697 mg/h · estimated
The screen shows local sodium concentration alongside model-derived whole-body values. The chart displays the complete illustrative session.

02 / WORKOUT SUMMARY
The whole session.
Review duration, averages and estimated loss totals in one place. Compare losses with logged intake to support your recovery planning, without automatically prescribing how much to drink or consume.
Average sweat rate is total estimated loss divided by session duration. Average sodium concentration is volume-weighted, keeping concentration and cumulative sodium loss consistent.

SMART HYDRATION ALERTS
A checkpoint. With context.
Combine estimated sweat loss with starting body weight and logged drinks to estimate your net fluid deficit. A configurable checkpoint prompts you to review your intake during the session.
Review logged fluid intake Example log
Amounts already consumed. Edit these illustrative entries; only entries up to the selected minute are counted.
Other recorded fluid or mass changes
Positive values mean additional net loss; negative values mean net gain. Zero is assumed in this example. Clear an unknown value to show a partial estimate.
The demo uses sweat loss − logged intake + other recorded changes, with approximately 1 kg per litre of water. It illustrates the interface, not NAESIA’s future validated algorithm.
The values shown are a static illustrative example. Enable JavaScript to explore progression.
A 2% checkpoint is an advisory setting, not a universal medical danger threshold. NAESIA does not directly measure body mass or diagnose dehydration. Starting weight and a complete intake log are required. Unknown additional changes are labelled as a partial estimate.

Below your 2% advisory checkpoint.
Your estimated fluid deficit has reached 2% of your starting body weight. Review your hydration status and fluid intake.
03 / PERSONAL ANALYTICS
A longer view.
Compare fluid and sodium losses across sessions, alongside workout duration and temperature. Similar fluid losses can come with different sodium losses.

04 / SWEAT PROFILE
A profile that is yours.
Build a record of your sweat response across training conditions. Use repeated sessions to understand your range rather than relying on one test.
