Rock salt, commonly known as “sendha namak” in India, has long been a staple in Ayurvedic practices and traditional home remedies. Known for its natural purity and mineral content, it's often seen as a healthier alternative to regular table salt. Many people use it during fasting, for cooking or even for treating minor ailments like indigestion or a sore throat.

With its growing popularity, it's easy to think of rock salt as completely safe. But like anything we consume regularly, too much of it or using it in the wrong way can have side effects. The disadvantages of rock salt may not be widely known, but they matter, especially if you're using it often or have existing health conditions.

Can we eat rock salt daily?

Yes, you can eat rock salt daily, but make sure it is in moderation. While it's a natural option and often preferred over table salt, overuse can lead to problems, especially if you have existing health concerns.

Rock salt (Sendha namak) side effects

Here are some of the most common rock salt side effects you should be aware of:

  • High blood pressure: Too much rock salt can increase blood pressure, putting extra strain on your heart and raising the risk of heart disease.
  • Bloating and dehydration: Excessive salt causes water retention, which may lead to bloating. It can also draw water out of your cells, leading to dehydration over time.
  • Lacks iodine: Unlike iodised salt, sendha namak doesn’t contain iodine, which is crucial for thyroid health. Using it exclusively could increase your risk of iodine deficiency.
  • Digestive discomfort: If consumed in large amounts, rock salt may irritate the digestive tract, causing nausea, vomiting, or diarrhoea.
  • Skin and pet irritation: When used outside as a de-icing agent, rock salt can irritate skin and harm pets’ paws, causing discomfort or minor burns.

Conclusion

While sendha namak is a natural alternative to regular salt, it’s important to be mindful of how much you consume. If you notice sendha namak side effects such as dehydration, nausea, fatigue, or unusual changes in your blood pressure, consult a doctor immediately. Timely medical advice can prevent complications and ensure better long-term health.

This is where a good health insurance policy becomes important. It can cover regular health checkups, consultations, and diagnostic tests, helping you stay informed about your health status. If you’re managing or at risk for serious conditions, critical illness insurance can offer added financial protection for major diseases, ensuring you're not burdened during treatment.
