Frequently Asked Questions
How much water do I really need?
A general rule is 30-35ml per kg of body weight. However, climate, activity levels, and health status can all influence your personal requirements.
Does coffee count towards my water intake?
Yes, tea and coffee do contribute to your hydration, although plain water is typically the best source. Most beverages and even water-rich foods (like watermelon) count.
Is it possible to drink too much water?
While rare, excessive water intake can lead to hyponatremia, where sodium levels in the blood become dangerously low. Drink when you feel thirsty if you're healthy.
