When it comes to bathing, detox is the process of soaking in mineral-rich water in order to absorb vital nutrients and rid the body of built-up toxins. Increasingly popular, detox bathing is a time-honored practice that dates back to ancient Rome and Egypt. The goal is to promote healing, flexibility and overall wellness. This type of bathing is said to help reenergize a tired body, purify the system and clear the mind. Many people take a detox bath at the first sign of illness.
