The Cell Phone & Cancer Connection

Currently, cell phones are classified as carcinogenic category 2b potentially carcinogenic to humans by the International Agency for Research on Cancer (IARC).  Among those in the scientific community, there is an ongoing debate about the possible harmful effects of regular cellular phone use, but to-date no study has managed to produce definitive results.   Yaniv Hamzany, from Tel Aviv University (Israel), and colleagues examined the saliva content of 20 “heavy use” cell phone users, defined as speaking on their phones for a minimum of eight hours a month. Their salivary content was compared to that of a control group, which consisted of deaf patients who either do not use a cell phone, or use the device exclusively for sending text messages and other non-verbal functions.  The team found that the saliva of heavy users showed indications of higher oxidative stress a process that damages all aspects of a human cell, including DNA through the development of toxic peroxide and free radicals. Higher oxidative stress is also considered a major risk factor for cancer. The lead researcher observes that: “This suggests that there is considerable oxidative stress on the tissue and glands which are close to the cell phone when in use."

Tip #192 - Stay Connected
Researchers from the University of Chicago (Illinois, USA) report that social isolation may be detrimental to both mental and physical health. The team analyzed data from the National Social Life, Health, and Aging Project, a nationwide US study involving 3,000 men and women, ages 57 to 85 years. They arrived at three key findings regarding the relationships between health and different types of isolation:

• The researchers found that the most socially connected older adults are three times as likely to report very good or excellent health compared to those who are least connected, regardless of whether they feel isolated.

• The team found that older adults who feel least isolated are five times as likely to report very good or excellent health as those who feel most isolated, regardless of their actual level of social connectedness.

• They determined that social disconnectedness is not related to mental health unless it brings feelings of loneliness and isolation.

Separately, Rush University Medical Center (Illinois, USA) researchers studied 906 older men and women, testing their motor functions (including grip, pinch strength, balance, and walking) and surveying their social activity, for a period of 5 years. Those study participants with less social activity were found to have a more rapid rate of motor function decline. Specifically, the team found that every one-point decrease in social activity corresponded to an increase in functional aging of 5 years, translating to a 40% higher risk of death and 65% higher risk of disability.
