Tell me more about drinking salt water in the morning


Drinking salt water in the morning has several potential benefits, primarily tied to maintaining adequate electrolyte levels. According to , this practice can help manage physical and mental states, especially during fasting or heavy caffeine consumption.


  1. Electrolyte Balance:

    • Salt contains essential electrolytes like sodium, which are crucial for neural and muscular function. These electrolytes facilitate chemical and electrical signaling in neurons 1.
  2. Blood Sugar Stabilization:

    • Salt water can help stabilize blood volume, reducing lightheadedness or shakiness that might be confused with low blood sugar levels 1. This is particularly useful for those practicing intermittent fasting.
  3. Enhanced Alertness:

    • Drinking salt water in the morning, especially for those consuming caffeine, can maintain sodium levels, preventing dehydration and promoting alertness 2.
  4. Hydration:

    • Adding salt to water can help retain hydration better, which is beneficial since sodium helps the body hold onto water. This is particularly important for those on low-carb diets or who exercise frequently 3.

      Salt for Fasting

      Andrew explains how ingesting salt can help manage mental and physical state during the fasting portion of intermittent fasting, and how it stabilizes blood volume and glucose levels. A small pinch of salt in water, ideally with lemon or lime juice, can offset lightheadedness and shakiness caused by low blood sugar, and make you feel better immediately.

What is the salt to water ratio? How much salt water should I drink in the morning?


suggests specific guidelines for the ratio of salt to water and the overall quantity to drink in the morning.

Salt to Water Ratio:

  • Amount of Salt: About half a teaspoon of sea salt.
  • Amount of Water: 16 to 32 ounces of water, ideally at room temperature 1.


  • Minimum Quantity: At least 16 ounces of water mixed with a small amount of sea salt.
  • Preferred Quantity: Up to 32 ounces depending on personal preference and hydration needs 1.

This practice helps maintain electrolyte balance, especially if you're consuming caffeine or exercising regularly in the morning. Adjusting the water temperature to room temperature can also make it easier to drink the required amount 1 2.

Always consult with a healthcare professional before making significant changes to your diet, especially if you have any underlying health conditions such as hypertension.
