300 blood drives canceled because of Sandy

About 300 American Red Cross blood drives have been canceled because of Superstorm Sandy, the organization said Tuesday, and more cancellations are expected.

"Patients will still need blood despite the weather," said Dr. Richard Benjamin, Red Cross chief medical officer, in a statement. "To ensure a sufficient national blood supply is available for those in need, both during and after the storm passes, it is critical that those in unaffected areas make an appointment to donate blood as soon as possible."

Because of the cancellations, more than 9,000 blood and platelet donations across 14 states - which would otherwise be available for those needing transfusions - did not take place, the organization said. The situation may worsen as the remnants of Sandy may continue to cause damage. FULL POST

Sandy's flooding: 5 things you need to know

Flooding overwhelmed parts of the East Coast Tuesday as a result of Superstorm Sandy.

In Little Ferry, New Jersey, floodwaters were six to eight feet deep, and about 75% of the city was underwater, according to the police chief.

“We have people who were actually on roofs of their homes in certain sections. We needed, actually, boats – we’re still using boats to get people out of the low-lying areas,” Chief Ralph Verdi told CNN. “I’ve been a police officer for 33 years. I’ve never seen this type of devastation from flooding.” FULL POST

Post-Sandy water safety tips

Ever heard the line, “Water, water, everywhere and not a drop to drink?" Never is that more true than during a hurricane.

Superstorm Sandy came ashore Monday night, flooding parts of the East Coast. After a natural disaster, your water may not be safe for use, according to the Centers for Disease Control and Prevention. This includes any water used for drinking, cooking, food preparation and/or personal hygiene.

Residents in Sandy’s path should be on the lookout for boil water advisories from their local and state departments of health, as well as from utility companies. These signify that your water may be contaminated.

Still, even if no notice has been issued, consumers should never assume that water in a flood-affected area is safe to drink, the Rhode Island Department of Health says.

Know how to keep weight off before you lose it

With all the talk about obesity in America, you might be surprised to know that most people are pretty good at losing weight.

Weight loss programs have proven effective in helping people drop pounds. But keeping them off is another story.

Studies have shown that overweight participants typically give up their newly learned health habits and regain 30 to 50% of the weight they lost within one year, even if they participate in a post-weight loss maintenance program.

“There’s something we’re missing in terms of what it takes to maintain our weight,” says Michaela Kiernan, an expert in behavioral weight management at the Stanford Prevention Research Center.

Easier to sweat while wet, study finds

During spinning class, I often find myself wishing I was in a pool. For one, water would make the sweat dripping down my back less noticeable. Two, it has to be easier to sneak a break when the instructor can’t see your legs below the surface.

A new study presented this week at the Canadian Cardiovascular Congress suggests there might also be other - more important - benefits to hydro-spinning.

The study analyzed cardiovascular data from 33 young, healthy participants who performed the same workout on a dry land stationary bike and on a water stationary bike.

Also called hydro-riders or aqua bikes, water stationary bicycles are anchored to the bottom of a pool so that cyclists are submerged up to their shoulders. Resistance can be added by changing the pedal size or, in some bikes, the angle of plates in the wheels.

Researchers found that participants’ oxygen consumption and average heart rates were lower while riding in the water. In other words, their cardiovascular systems were working more efficiently to do the same amount of exercise.
