Is the ‘Salt-Water-Lemon’ Morning Routine Hurting Kidneys? Experts Weigh In

Wellness trends frequently promise simple fixes for the complex functions of the body; one such ritual has been drinking salt water with lemon every morning. Sold as a detox drink, digestion aid, or metabolism booster, this habit has taken deep roots in all walks of life, without thoughtful consideration regarding kidney function or maintaining fluid and salt balance.

From the perspective of a nephrologist, any kind of daily activity that helps to boost the intake of salt is worth noting.

The kidneys constantly filter blood to regulate sodium and water levels.
"When excess salt is consumed daily, the kidneys are forced to work harder to excrete it while maintaining fluid balance. Over time, this can contribute to rising blood pressure and puts more stress on the kidneys," explained Dr Aniket Hase, Consultant Nephrologist, Jupiter Hospital.

While healthy kidneys may make temporary adaptations, repeated exposure to unnecessary sodium will make kidney function suffer in the long term, especially when combined with today's high-salt diets.

Lemon Isn't the Problem-Salt Is

Adding a clinical perspective, Dr Nikhil Bhasin, Consultant Nephrologist and Renal Transplant Physician, Wockhardt Hospitals Mumbai Central, clarifies that lemon itself is not harmful.

"Lemon contains citrate, which can actually reduce the risk of certain kidney stones. The issue arises when salt is added regularly, especially in unmeasured amounts," he said.

"Once salt is introduced, the drink shifts from being hydrating to sodium-heavy, prompting water retention and potential increases in blood pressure-particularly in salt-sensitive individuals," added Dr Bhasin.

Who Should Avoid This Routine Completely?

Both nephrologists strongly advise against daily salt water consumption for:

  • People with high blood pressure
  • Individuals with diabetes or early-stage kidney disease
  • Those prone to kidney stones
  • Older adults with age-related decline in kidney filtration

"For these groups, even small daily increases in salt can quietly accelerate kidney damage," warned Dr Hase.

The Detox Myth Needs Rethinking

"There is no scientific evidence that salt water detoxifies the body," emphasised Dr Bhasin. "The kidneys and liver already detoxify efficiently when supported with proper hydration. Adding salt does not enhance this process and may do the opposite."

Salt water has medical relevance only in specific scenarios such as severe dehydration, prolonged heat exposure, or excessive sweating, not as a daily wellness habit.

A Kidney-Friendly Way to Start the Day

From both specialists' perspectives, the safest morning routine is simple: plain water or lemon water without added salt, which supports hydration without disturbing electrolyte balance.

Bottomline

Salt water with lemon may sound like a healthy ritual, but practiced daily, it can quietly burden the kidneys, especially in individuals with existing risk factors. As Dr Hase and Dr Bhasin reiterated, kidney health depends on moderation, mindful intake of sodium, and evidence-based habits-not detox trends. Simplicity works best when it comes to taking care of your kidneys.
