There are a number of ways that you can wind down from a stressful week such as going to the gym, hanging out with friends or even being out in nature. But, you can add one more thing to that list: baths.A study published in BMC Complementary Medicine and Therapies indicated that baths can help to reduce symptoms of depression, making it easier to live a happier life.Researchers, funded by the University of Freiburg noted that more than 350 million people suffer from depression worldwide, but only a third of those people respond to medication in the form of antidepressants.
