Health note. Waterline is an informational tool, not medical advice. Extended water fasting can be dangerous if you are pregnant or breastfeeding, underweight, diabetic, on medication, or have a history of disordered eating. Talk to a doctor before fasts longer than 24 hours, and stop immediately if you feel faint, confused, or unwell.
