Health Buzz: Maine May Require Cellphone Warning and Other News

H1N1 vaccine more widely available; strength training a must for a "body breakthrough."


Maine May Require Cellphones to Carry Warning

Cellphones might soon carry warning labels in Maine, the Associated Press reports. State legislator Andrea Boland has proposed a bill that would require cellphone labels and packaging to indicate that radiation emitted from the devices may cause brain cancer. Warnings would instruct users to hold cellphones away from their head. The report points out that studies have yet to show a decisive link between cellphones and cancer, according to the National Cancer Institute. "Scientists still caution that further surveillance is needed before conclusions can be drawn," according to the institute's website.

H1N1 Vaccine Available, But Will Americans Get It?

The Centers for Disease Control and Prevention estimates that 1 in 6 Americans has been infected with H1N1 and that the epidemic is actually on the wane. But now finally there's enough vaccine to go around, U.S. News's Deborah Kotz writes. Available doses were expected to have topped 100 million in the country by last Friday. At least 24 states and some other counties and towns have enough to open distribution to everyone.

The CDC's big worry is that H1N1 will return with a vengeance in January after college kids come home for the holidays and infect the rest of their families. The agency would like those families to be vaccinated before their germinators return. And this is a legitimate point, Kotz writes. After all, there have been a number of documented H1N1 infections that have shown to be resistant to Tamiflu, possibly a sign that the virus is mutating into a drug-resistant bug. "We have a wonderful window of opportunity to prevent or lessen a third wave," Health and Human Services Secretary Kathleen Sebelius said at a news conference. The 1957 Asian flu pandemic hit the country with a second wallop after the first fall outbreak, possibly triggered by holiday travel. Read more.

Rachel Cosgrove on the Female Body: Start With Strength Training

When women say they need to do more exercise, they're usually thinking of aerobic activity: running, a spinning class, speed-walking. But making aerobic workouts the centerpiece of a fitness plan is not the best way to go, says Rachel Cosgrove, cofounder of Results Fitness in Southern California. In her new book, The Female Body Breakthrough, she instead advocates a focus on strength training, which she says is the real key to losing fat and looking better. U.S. News's Katherine Hobson recently chatted with her.

Cosgrove says women need a different strength-training workout from men because they tend to be more quad-dominant [meaning they use the quadriceps more than the butt and hamstring muscles]. It's a real weakness for a lot of women; they have what Cosgrove calls "gluteal amnesia" because their brains aren't used to switching on their butt muscles. Women also have wider hips, and the pelvis tips forward, which stretches the hamstrings and makes it harder to engage the glutes. By engaging the core, she says, you can pull your pelvis under you and stretch out your hip flexors. You can do exercises that will switch on the butt muscles and hamstrings. Read more.
