I have a Magnesium Chloride topical form of application on hand for the relief of tension, insomnia, stress, and muscle spasm, specifically leg cramps in my case for emergency use after working long hours without properly hydrating and so waking with screaming Charlie horses.
Also, I recently happened upon a sort of infomercial, while viewing watercolor tutorials, about the effectiveness of engaging in artwork, regardless of talent level, to induce a sense of well-being and reduce depression (dwelling on the past) and anxiety (dwelling on the future) by keeping a focus in the present moment while drawing or painting or other type of creative work.
