Study: Exercise Improves Quality of Life for Breast Cancer Patients

iStockphoto/Thinkstock(NEW YORK) -- A new study finds that exercise can improve the quality of life for breast cancer patients, Health Day reports.

Researchers from the University of Miami examined the exercise levels and mental and physical health of 240 women with breast cancer four to ten weeks after surgery. They found that the women who were physically active suffered less from depression, fatigue and had a better quality of life during cancer treatment following surgery.

The same researchers previously found that breast cancer treatment is also improved by stress management, Health Day says.

Study Raises New and Troubling Questions About Energy Drinks

Photo Courtesy - Getty Images(MIAMI) -- Despite the growing popularity of energy drinks that tout enhanced concentration and the ability to keep you awake for long periods of time, a study released Monday warns that adolescents and young adults should be aware of the potentially unknown side effects of their beverage choices.

The study, Health Effects of Energy Drinks on Children, Adolescents, and Young Adults, was released by a group of doctors at the Leonard M. Miller School of Medicine at the University of Miami.

The group found that the amount of caffeine and other stimulants in energy drinks, which are not regulated by the Food and Drug Administration, can be harmful to young adults and adolescents -- especially those with diabetes or attention-deficit/hyperactivity disorder.

The survey shows that while 30 to 50 percent of the target group had consumed an energy drink, 46 percent of reported caffeine overdoses in 2007 occurred in those 19 or younger.

A lack of governmental regulation is just one of the many reasons medical professionals say the younger age group needs to be careful with energy drinks and supplements.

"The marketing is usually geared towards children, so you have to educate your child to not listen to these marketing schemes. They do a really great job at making kids feel like they need this product to enhance their performance at school or in their activities, and they don't," said Tara Haywood, a pediatric nutritionist at the Cleveland Clinic.

Haywood warns that energy drinks can have caffeine levels up to three times as high as a regular 12-ounce can of soda.

Those with special conditions should be especially aware of what they're putting into their bodies, another doctor warns.

"There's a lot of children who are on medication for ADHD, who would potentially be harmed by high doses of caffeine, also if a child has a heart condition or diabetes, these energy drinks can cause abnormal fluctuations in their blood sugar," said Dr. Kyle Kaufman, assistant professor of internal medicine and pediatrics at the University of Cincinnati.

If those blood sugar levels do get too high, Kaufman said, an abnormal heartbeat can be the dangerous result.

So with pressure to perform both at school and on the job, what are those who can't kick the energy drink habit to do?

"Think critically about what the drink is offering. Certainly certain combinations of energy drinks or supplements with certain medical conditions can be problematic. I would generally recommend [that someone with medical problems] not take those supplements," said Dr. Kaufman.

Because energy drinks and supplements are not regulated by the FDA, the advertisements for these products can make unproven statements, and their ingredients are uncontrolled.

"In a world where a lot of both adults and kids are being asked to be awake for longer periods of time, these type of energy drinks and supplements purport to make you better at what you're doing, help you stay awake longer and that kind of marketing is very persuasive," Dr. Kaufman warns.
