Himalayan Bath Salt Lamps and Essential Oils

One of the feedback I got from the podcast on sleep was to consider Himalayan Bath Salts, and Essential oils.
According to Snopes, Himalayan Bath Salt Lamps do nothing other than provide a lighting source.

Unlike the lamps, there is some science on Aromatherapy and essential oils. Although one quote concerned me enough to avoid them, "Lavender and tea tree essential oils have been found to have some hormone-like effects. They have effects similar to estrogen (female sex hormone) and also block or decrease the effect of androgens (male sex hormones). "

No thanks 

On the lighting side, Seasonal Affective Disorder (SAD) lightning seems like a better solution than salt lamps, maybe I'll get one of these: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4673349/

What is your experience with the three of these? When someone recommends a cure or solution to one of your issues, do you look up the science to validate its efficacy?
