Ben Welter - Friday, June 26, 2015

Hammacher Schlemmer headache wrapWrap your head around this: Phase change materials are being used to relieve headache pain. Hammacher Schlemmer says PCM gel packs allow the new Superior Headache Relieving Wrap to "stay cool 200% longer than typical models." A spokeswoman was unable to identify the PCM type but said it is "nontoxic and nonflammable," with a melting point of 14º C.

The older gel headache band working great relieving cluster and migraine headaches. The new one with 8 cold pads actually makes cluster and migraines worse, the points between between the packets create points which hurt the head when used. very uncomfortable and useless.
