The
Dangers of Teen Texting, Social Networking
 A
startling new study suggests a disturbing association between excessive
social networking and texting by teenagers and participation in a wide
range of poor health behaviors including cigarette, alcohol and drug use,
increased sexual activity and violence. The study defined
"hypernetworking" as spending three-plus hours per school day on
social network sites such as Facebook, and "hypertexting" as
sending in excess of 120 text messages per school day. Teens guilty of
hypernetworking (11.5 percent of teens surveyed) were:
- 79% more likely to have tried alcohol
- 69% more likely to be binge drinkers
- 62% more likely to have tried cigarettes
- 84% more likely to have used illicit drugs
- 94% more likely to have been involved in a physical
fight
- 69% more likely to have had sex
- 60% more likely to report four or more sexual
partners
An even larger percentage of teens (19.8 percent) were guilty of
hypertexting and displayed similar patterns of poor health behaviors:
- More than twice as likely to have tried alcohol
- 43% more likely to be binge drinkers
- 40% more likely to have tried cigarettes
- 41% more likely to have used illicit drugs
- 55% more likely to have been involved in a physical
fight
- Nearly 3.5 times more likely to have had sex
- 90% more likely to report four or more sexual
partners
The study by researchers at Case Western Reserve School of Medicine does
not show cause and effect, which means it does not prove that excessive
social networking and texting caused these unhealthy behaviors to manifest
(or vice versa). That said, the study suggests enough of a potential
connection to make parents think twice before allowing their teen unlimited
text- messaging capabilities and unsupervised access to the Web.

Support
Yourself From the Ground Up
 Anyone who has
experienced foot problems understands all too well that it can affect the
rest of the body. The feet are your foundation, much like the foundation of
a house. If that foundation suffers, the entire structure suffers right
along with it; in some cases, it can come crashing down. Fortunately, that
same logic applies in reverse: optimizing foot performance and health is
like strengthening your foundation; the result can be a stronger, more
durable you from the ground up.
A recent research review provides an excellent illustration of this
principle. It involves the example of patients suffering from arthritis and other rheumatic diseases, which can rack
the entire body with pain, stiffness and movement limitations. According to
the review, biomechanical evidence suggests that "foot orthotics and
specialized footwear may change muscle activation and gait patterns to
reduce joint loading. Emerging evidence suggests that orthotics, specific
shoe types and footwear interventions may provide an effective nonsurgical intervention
in rheumatic diseases."
The takeaway here seems clear: Support your feet and your feet will support you. An
increasing body of research suggests foot orthotics can positively impact
foot health (and thus whole-body health) in numerous ways. Talk to your
doctor to learn more.

Cut
Your Skin Cancer Risk
 Let's review what we
know about skin cancer, skin protection and your health: If you stay out of
the sun, tanning beds, etc., your chances of getting skin cancer
are remarkably low (although not completely eliminated); if you get
regular, moderate sun exposure, you'll ensure adequate vitamin D absorption (approximately 10 minutes a day will
give you upwards of 10,000 IU; the RDA for vitamin D is 400 IU) and be less
likely to develop skin cancer compared with people who experience painful sunburns – even if you spend more overall time
in the sun than they do. And while debate runs thick about the
effectiveness and safety of sunscreen, a recent study published in the Journal of Clinical Oncology
emphasizes that if you apply a little lotion, your odds of suffering
melanoma go way down.
While not the most common form of skin cancer, melanoma is the most
dangerous form, causing approximately 75 percent of all skin cancer-related
deaths. More than 160,000 new cases are diagnosed worldwide each year.
Melanoma can appear on skin sites that do not receive sun exposure, so it's
important to check your body regularly and report any skin irregularities
to your doctor.
Sunscreen may help prevent melanoma, but it blocks vitamin D absorption,
which means if you use it regularly, you need to ensure adequate vitamin D
intake from food or supplements. And make sure you don't take it for
granted; think moderation when it comes to the sun. You'll be happy you
did. Your doctor can tell you more about skin health and how to enjoy the
summer months while keeping your skin safe at the same time.
