How to Heat Up Epsom Salts

There are a variety of safe methods to heat up Epsom salts for therapeutic use depending on your preference. Boiling water is one method, where you can add Epsom salt to a pot of boiling water and stir until the salt dissolves. The recommended ratio is two cups of Epsom salt per gallon of water. It is essential to let the water cool down until it reaches a comfortable temperature before use.

Another method is by using a hot water bottle, where you can add Epsom salt and hot water to the bottle, shake it until the salt dissolves and cover the bottle with a towel before use. It’s advised to not exceed 20-30 minutes of use.

Moist heating pads can be used to heat Epsom salt by following the instructions on the packaging. Sauna or steam room visits can also provide a therapeutic effect by exposing the body to moist heat.

Microwave radiation is also a quick and convenient method, but caution should be taken. Never heat Epsom salt on its own without water, as it can explode and damage the microwave. Instead, heat it in a microwave-safe bowl with a water solution and stir occasionally. Heat in increments of 15-20 seconds for a period of 1-2 minutes total.
