What is 'Sole' Water?
'Sole' (pronounced 'so-lay') water is simply a solution of water fully saturated with Himalayan salt. Proponents suggest that consuming a small, diluted amount of this brine daily provides the body with electrolytes and trace minerals. While Himalayan salt contains a multitude of minerals, it's important to remember these are in very small, trace amounts and mainly composed of sodium chloride.
The Allure of Himalayan Salt
The primary appeal of Himalayan salt over regular table salt lies in its mineral profile. Unlike highly refined table salt, which is often stripped of its minerals and then fortified with iodine, Himalayan salt is an unrefined product containing trace minerals like potassium, magnesium, and calcium. It is the iron oxide in the salt that gives it its characteristic pink hue. Many people are drawn to unrefined products, believing them to be inherently healthier, and this perception drives much of the interest in sole water.
Potential Benefits and the Science Behind Them
When added to water, Himalayan salt dissolves into its ionic components, including sodium. These ions, known as electrolytes, are vital for numerous bodily functions.
- Improved Hydration: The most significant, evidence-based benefit is improved hydration. The body requires a balance of water and electrolytes to effectively absorb fluids. For athletes or those who sweat heavily, adding a pinch of salt to water can help replenish lost sodium and electrolytes, aiding in water absorption and preventing dehydration.
- Trace Minerals: Sole water provides a negligible amount of trace minerals. While the presence of minerals like potassium, magnesium, and calcium is often highlighted, the concentration is so low that it is not a nutritionally significant source. One would need to consume an unhealthy and dangerous amount of salt water to get meaningful mineral benefits.
- Digestion Support: Some anecdotal reports suggest that salt water can help stimulate digestive enzymes and hydrochloric acid production in the stomach. However, strong scientific evidence for this specific benefit is lacking.
The Risks and Downsides of Salt Water Intake
Despite the purported benefits, the primary risk of drinking salt water is excessive sodium intake. The health dangers associated with consuming too much sodium are well-documented and apply to all types of salt, regardless of how unprocessed they are.
- High Blood Pressure: Increased sodium intake can lead to elevated blood pressure in some individuals by causing the body to retain water, which increases blood volume and puts extra strain on blood vessels.
- Water Retention (Edema): Excess sodium causes the body to hold onto water, leading to bloating and swelling, particularly in the hands, feet, and face.
- Kidney Strain: The kidneys must work harder to filter and excrete excess sodium. Over time, high sodium intake can strain the kidneys, increasing the risk of kidney disease and kidney stones.
- Iodine Deficiency: While some Himalayan salts may contain a minute amount of natural iodine, it is not a reliable source. Unlike most table salts, Himalayan salt is not fortified with iodine, an essential nutrient for thyroid function. Relying solely on Himalayan salt could lead to iodine deficiency.
How to Make 'Sole' Water Correctly
To prepare sole water, you create a concentrated brine that is then diluted for consumption. This prevents you from ingesting an unhealthy amount of salt at once. The key is to start with a saturated solution and use only a small amount of that concentrate per glass of water.
- Create the Concentrate: Fill a glass jar about one-quarter full with Himalayan salt crystals or coarse ground salt. Fill the rest of the jar with filtered water, leaving some space at the top. Seal with a non-metal lid.
- Saturate the Solution: Shake the jar well and let it sit for 12-24 hours. You will know the solution is fully saturated when some salt crystals remain undissolved at the bottom. If all the salt dissolves, add more until it no longer dissolves.
- Dilute to Drink: Each morning, mix just one teaspoon of the concentrated sole solution into an 8-ounce glass of fresh water. This dilutes the salt content to a safe and manageable level.
Comparison: Himalayan Salt Water vs. Plain Water
For most people with a standard Western diet, adding more salt is unnecessary. However, for those with high electrolyte loss, a small amount can be beneficial. Here is a comparison of adding Himalayan salt to water versus drinking plain water.
| Feature | Himalayan Salt Water (Sole) | Plain Water |
|---|---|---|
| Hydration | Provides electrolytes (sodium) to enhance water absorption, especially post-exercise. | Excellent for standard hydration, flushes waste. The body can absorb enough without added salt unless sweating heavily. |
| Mineral Content | Contains trace amounts of minerals like potassium, magnesium, and calcium. | Does not contain added minerals unless mineral-fortified or from a hard water source. |
| Sodium Intake | Increases overall sodium consumption. Risks high blood pressure and other health issues if consumed excessively. | Does not add sodium to your diet. |
| Iodine | Lacks added iodine, which is often found in table salt. Not a reliable source. | Contains no iodine. Users should get iodine from other dietary sources. |
| Risk Factor | Potential for excessive sodium intake if not used correctly. Not advised for those with high blood pressure or kidney disease. | Minimal risk, safe for general consumption. |
How Much Is Too Much?
For the average person, adding salt to water is unnecessary because most Western diets already contain excess sodium from processed foods. The World Health Organization recommends limiting daily sodium intake to less than 2,000 mg. For most people, a single teaspoon of sole concentrate (providing a small amount of sodium) mixed into a glass of water is unlikely to cause issues but should still be counted toward total daily intake. Individuals with health conditions like high blood pressure, heart, or kidney problems should consult a doctor before incorporating sole water into their routine. The key is moderation and being mindful of overall sodium consumption. For those seeking electrolyte replacement after intense exercise, a purpose-built hydration powder is often a more balanced option.
Conclusion: The Verdict on Himalayan Salt Water
Adding a small, diluted amount of Himalayan salt in my water offers negligible benefits for most people but can assist with hydration and electrolyte balance for specific individuals like heavy sweaters. While proponents often cite its trace mineral content, the amounts are too small to offer a significant nutritional advantage. The core risk is consuming too much sodium, which is already a widespread issue. Ultimately, plain water remains the best hydration choice for the majority.

Individuals interested in sole water should exercise caution, prioritize moderation, and consider their overall sodium intake before adopting this trend.
