Generic AI prompts telling users to 'drink 8 glasses of water' represent outdated and physiologically inaccurate science. True hydration must scale dynamically with human biology. The Physiological Hydration Engine computes exact milliliter targets and maps them onto a strict circadian temporal schedule.

Algorithmic Precision

  • Metabolic Baseline Processing: Evaluates the biological baseline (35ml per kg) against strict modifiers for metabolic exertion (from sedentary to elite athlete) and environmental thermal stress (cold vs tropical climates).
  • Circadian Fluid Distribution: Calculates the exact waking duration (between the provided wake and sleep timestamps) and automatically segments the total hydration target into 6 strategic ingestion milestones (e.g., 'Morning Flush', 'Pre-Sleep Sip').
  • Temporal Rollover Math: LLMs frequently fail when parsing nighttime sleep schedules (e.g., waking at 14:00, sleeping at 06:00). The underlying V8 engine utilizes robust mathematical rollovers to flawlessly navigate nocturnal and shift-worker workflows.
  • Zero-Dependency Native Execution: Bypasses external health APIs, ensuring sensitive biological inputs are processed strictly on local infrastructure.

5 tools expose this connector's capabilities to your AI agent.

calculate_full_hydration_plan

Requires weightKg, and accepts optional physical/climate/time modifiers. Computes optimal physiological hydration targets and synthesizes a complete circadian fluid distribution schedule in one step

calculate_hydration_schedule

Provide totalMl and optionally wakeTimeStr and sleepTimeStr. Distributes a specified total water volume evenly across waking hours into specific physiological milestones

calculate_hydration_target

Provide weight in kg. Activity level defaults to sedentary and climate to temperate. Calculates the daily water volume requirement based on body mass, physical exertion, and thermal environment

get_activity_hydration_modifier

g. sedentary, athlete). Retrieves the exact biological water penalty (in ml) caused by specific physical exertion levels

get_climate_hydration_modifier

g. cold, tropical). Retrieves the exact thermal water penalty (in ml) caused by specific environmental climates

I weigh 80kg, am highly active, live in a hot climate, wake up at 07:00 and sleep at 23:00. How much water?

Using the calculate_hydration_schedule tool: The biological engine computed a target of 4100 ml (4.1L). Your first segment is a 615ml Morning Flush at 07:15, with steady distributions until a final 410ml Pre-Sleep Sip at 22:30.

Build a hydration plan for a sedentary 60kg person in a cold climate (waking 09:00, sleeping 01:00).

Using the calculate_hydration_schedule tool: The computed target is strictly 2100 ml (2.1L). The circadian schedule maps the final hydration window precisely to 00:30 to avoid sleep interruption.

Yes. The temporal rollover math guarantees that if you wake up at 18:00 and go to sleep at 08:00, the schedule perfectly plots the 14-hour window across midnight without chronological errors.
