Ice bathing and Ice tubs have become a popular tool among athletes and those seeking recovery and rejuvenation. But what if I told you there's a secret ingredient that can enhance your ice tub? Let me introduce you to Epsom salt and the five most effective ways to incorporate it into your ice tub routine, taking your ice tubbing to a new level of effectiveness.
What is Epsom Salt?

Epsom salt, also known as magnesium sulfate, is not just a common household ingredient but also boasts an impressive range of health benefits. It consists of magnesium, absorbed through the skin, adding an extra dimension to your ice tub.

The 5 Most Effective Ways to Include Epsom Salt in Your Ice Tub:
  1. Magnesium for Muscle Relaxation: Epsom salt is rich in magnesium, alleviating sore muscles and reducing inflammation. Add 2-3 cups of Epsom salt to your ice tub to reap this benefit.
  2. Renew Skin with Exfoliation: Combine Epsom salt with olive oil or your preferred body oil to create a natural exfoliating blend. This will remove dead skin cells, leaving your skin smooth and renewed.
  3. Promotes Recovery and Revitalization: Epsom salt helps expedite the recovery process by enhancing blood circulation and relieving tired muscles. It's a perfect addition to your routine after intense workouts.
  4. Stress Relief and Calming Effects: The amount of magnesium in Epsom salt can reduce stress and promote relaxation. A soothing ice tub with Epsom salt can be the perfect remedy for relieving stress and tension.
  5. Increased Mineral Absorption: By absorbing magnesium from Epsom salt during the ice tub, your body can intake this essential mineral, contributing to better muscle function and nervous system health.
Can Epsom Salt Affect Water Temperature?

Epsom salt itself does not directly impact water temperature. When dissolved in water, a chemical reaction occurs that absorbs heat from the surroundings, potentially causing a slight decrease in water temperature. This is known as an endothermic reaction, where the chemical process requires energy, resulting in a minor cooling effect on the water. While adding Epsom salt to water may make it feel cooler, it doesn't significantly alter the water's temperature.

Can Epsom Salt Affect Water Purity?

Yes, Epsom salt itself can contribute to improving water purity in certain ways.Impurity Removal: Epsom salt can assist in removing impurities from water through a process called flocculation. When used correctly, Epsom salt can help clump tiny particles together, making it easier to remove them from the water.Water Softening: Epsom salt is known for its softening properties, meaning it can reduce water hardness by removing or reducing the concentration of minerals like calcium and magnesium.

Skincare: While it doesn't directly purify the water, adding Epsom salt to a tub can aid in cleansing and softening the skin by helping remove dead skin cells and absorbing impurities from the skin's surface.

However, it's important to note that Epsom salt is not typically used as the primary method for water purification. There are more effective methods and chemicals for water treatment if the aim is to make the water completely pure. For smaller purposes such as baths and smaller water containers, Epsom salt may still offer certain benefits for purity and softening.

How to Get the Best Effect from Epsom Salt in My Ice Tub?

How Do I Add It, and How Much for It to Be Effective? Epsom salt can be beneficial in an ice tub as it may help alleviate muscle soreness and reduce inflammation. To get the best effect:Quantity: Typically, use about a handful of Epsom salt per standard Nordkilde ice tub with water. You can adjust the quantity to your personal preference, but avoid overdoing it.


Add the Epsom salts while filling the tub with water. Stir the water to help the salts dissolve completely. Temperature: When creating an ice tub, it might be a bit challenging to fully dissolve the salts as cold water may have a harder time dissolving them. You can try dissolving the salts in warm water first and then add ice to cool it down to the desired temperature.
Softening and Mixing: Once the salts are dissolved, mix in the ice into the tub and ensure the mixture is evenly distributed.

Epsom salt is primarily magnesium sulfate, absorbed through the skin. It's believed to help reduce muscle tension and soreness. It's also essential to note that while many find it beneficial, it might not have the same effect on everyone.


Epsom salt isn't just a simple ingredient for your ice tubs; it's a game-changer for your recovery and well-being. Its ability to alleviate soreness, calm the mind, and rejuvenate the skin makes it an indispensable part of any ice tub routine. So, next time you prepare your ice tub, add a handful of Epsom salt and feel the difference. Have you tried adding Epsom salt to your ice tubs before? Let me know how it has impacted your
