A study recently published in the online journal PLOS ONE expands on a 2002 investigation into pain sensitivity and the effects of exposure to, rather than ingestion of, pain medications. Test subjects were instructed to immerse a hand into a freezing-water bath until it became too uncomfortable. Then, they were told to evaluate the design of several products for a different study, after which they subjected themselves to the freezing-water bath again. Of the 25 subjects who were given a bottle of ibuprofen to hold and study, ten of those said that they felt less pain during the second water bath than the first.

Psychologists and lead researchers Abraham Rutchick and Michael Slepian say it’s not clear exactly how the increase in tolerance worked, but the study did “[demonstrate] that objects in the environment can nonconsciously decrease pain sensitivity.” They are careful to note that their subjects were all healthy undergraduate students, and that results might differ with older people with specific ailments such as arthritis.
Combining years of neurological research and mindfulness techniques, Dr. Heather Berlin helps us better understand how the body’s most complex organ can easily be misled into negative thinking - and how we can stop that from happening.
In a survey conducted by AT&T, more adults than teens admitted to texting while driving. Interestingly, 60 percent of those said they only started doing so in the last three years, and 98 percent of them knew it was unsafe.
