StretchLearn Course
A practical, research-backed guide to hydration, electrolytes, and sustained energy.
Course Overview
This course covers the physiology behind fluid regulation, electrolyte roles, and dehydration effects on the body and brain. You will learn to calculate your personal fluid targets, read your body's early dehydration signals, and build evidence-backed hydration habits around exercise, work, and sleep. By the end you will have a personalised hydration protocol you can follow immediately.
Learning Outcomes
Calculate your personal daily fluid requirement using body-weight and activity formulas
Identify the five early signs of dehydration before thirst becomes noticeable
Distinguish the roles of sodium, potassium, and magnesium in fluid and energy balance
Design a timed hydration schedule anchored to your existing daily routine
Adjust fluid and electrolyte intake for exercise, heat, altitude, and illness
Evaluate commercial sports drinks and electrolyte products against evidence-based criteria
Curriculum Preview
Preview the course structure, see how the modules build on one another, and understand the path this program is designed to take you through.
Understand how the body regulates fluid, why dehydration impairs both physical and cognitive performance, and how to calculate your own daily fluid targets.
Understand the specific roles of sodium, potassium, magnesium, and calcium in fluid retention, nerve signalling, and energy production, and learn when supplementation makes sense.
Translate fluid targets into a timed, habit-anchored daily schedule that prevents deficits from accumulating and sustains energy across the waking day.
Fine-tune your hydration approach for special circumstances — travel, illness, stress, and aging — and build the monitoring systems that sustain the habit for years.
Built for Application
This program is designed around progression: focused lessons, structured modules, applied resources, assessments, and a course rhythm that turns information into usable capability.
