As someone who experienced hypersensitivity for much of my life, I must say I agree it is a two edged sword . I am still very sensitive to low frequency electrical and machinery hums and always sleep with a white noise machine in the room . At home I use fans and air filters to circulate and clean air, as well as for their action as white noise machines . I’ve noticed that many times other people are not bothered or don’t even hear the low frequency sounds that i cannot tolerate. For many years I used wax earplugs which didn’t always work . Besides for decades I heard voices ( which were annoying to me) I eventually realized were being generated from inside me . Haloperidol and too rapid withdrawal from it almost cost me my life. I’ve learned so much on this journey of personal experimentation to get out from under intolerable phenomena . Here’s what helped me the most : The money which became available to remove all metal from my mouth , all traces of root canals , and was checked for cavitations. I had 15 amalgam’s of various sizes in my mouth ( which are composed of 53% mercury) . I was a new person , falling asleep was no longer a problem , no more voices , super sensitivity subsided except for low frequency sound sensitivity which was reduced . I attribute that to damage caused by 15 electro- shock treatments forced on me in my youth. Also helpful was understanding the underlying truths of Traditional Naturopathy , Homeopathy , and learning the energy healing system Yuen Method . Before the fillings were removed when things got bad I had to invent an improved mineral bath therapy for extreme states which was to take about 1500 mg.of Niacin ( not the non-flushing ) and once the redness appeared to enter a mineral bath filled hot water bath. Rubbing skin down with a foot long luffa which wonderfully soothed the itching . Even during an on coming extreme state this bath enabled sleep and could help one regain equilibrium.I used BathTherapy brand mineral bath which had lithium and other minerals in it (not the original), although now I believe there are even better more pure mineral bath mixtures that have lithium and other minerals available in them, that can be found online in bulk quantities . I used this type of bath as needed . Eventually I moved near a national recreation area so I could easily access outdoor wilderness area’s every day .
