Quick answer: Water and electrolytes such as sodium, potassium and magnesium keep cells working and help the kidneys eliminate waste in urine. Your body regulates fluid balance through the kidneys and hormone systems like renin-angiotensin-aldosterone (RAAS). During a detox, aim for steady hydration through the day, include mineral-rich foods, and watch for signs of dehydration.
Why hydration matters
Water makes up a large share of your body and is needed for circulation, digestion and kidney filtration. Electrolytes help nerves and muscles work. See how the kidneys support detox.
How your body balances fluids
The renin-angiotensin-aldosterone system (RAAS) helps regulate blood pressure, fluid and sodium-potassium balance. When fluid or blood pressure drops, these hormones help the kidneys hold on to sodium and water.
Benefits of staying hydrated
- Regulates body temperature
- Cushions joints
