How It Works
Why Proper Hydration Matters
Water is essential for nearly every bodily function, from regulating temperature and removing waste to lubricating joints and protecting sensitive tissues. Staying properly hydrated improves energy levels, cognitive function, and overall health.
Our bodies lose water continuously through breathing, sweating, and waste elimination. This is why consistent hydration throughout the day is crucial for maintaining optimal health and wellbeing.
