Don't get so excited

When you're on an endorphin high, you're less likely to resist tempting food, a research study shows.

Happy people make healthier dietary decisions in general, but if you're too excited, that happy/healthy link loses its oomph.

In one study, one group watched a positive but calm movie clip while another group watched a positive but arousing clip. Then they were both given the choice between a snack of grapes or M&M's.

The ones who watched the action-packed clip were more likely to choose M&M's, and the ones in the calm clip group who did choose M&M's were more likely to monitor the amount they ate.

Exercise, which releases endorphins, was added to the routine. Everyone watched the calm clip, but some did a little exercise while some were sedentary.

The ones who exercised were more likely to choose the M&M's.

The conclusion? It's the shortage of mental energy that leads to less healthy choices.

Overtime may harm heart

Consistently working long hours could give your ticker a beating, a new study suggests. Researchers who looked at data from 6,000 British civil servants found that those who worked three or more hours of overtime each day had a 60 percent higher risk of developing serious heart problems. More than 350 of the workers died from heart disease, or had heart attacks or angina, HealthDay reports. More stress at work and less time for exercise or doctor's visits may help explain the findings, one expert told HealthDay.

Hookah gains popularity

A new study of young adults points to a surge in the popularity of hookah, tall water pipes used to smoke flavored tobacco. Researchers in Montreal surveyed 871 people ages 18 to 24 and found that 23 percent had smoked with a hookah in the past year, roughly three times the percentage revealed by a survey a year earlier., HealthDay reports. A similar trend may exist in the United States.

Hookah lounges have been sprouting up across the country in recent years, catering to a predominantly young clientele and often stationed near college campuses, U.S. News and World Report's Lindsay Lyon has reported. Their growing popularity as social hangouts for 18-to-24-year-olds prompted the American Lung Association to issue a report in 2008 identifying hookah smoking as a major health risk.

Hookah smoke contains some of the same hazardous components found in cigarette smoke, which have been linked to heart disease, cancer and addiction, Lyon wrote. What's more, a water pipe smoker may inhale as much smoke during a single hookah session as a cigarette smoker would inhale by blazing through 100 cigarettes.

Bigger men, bigger tumors

Heavier men have bigger, more aggressive prostate tumors, according to new research from Henry Ford Hospital presented Wednesday.

The findings, presented in San Francisco at the American Urological Association's annual meeting, were based on a six-year study of Detroit-area men. They show that the more a man weighed, the larger his prostate tumor.

They also suggest obese men should at least have an annual digital rectal exam, performed by a doctor wearing a glove, because a blood test is not as accurate in finding prostate cancer in heavier men, said Dr. Nilesh Patil.

Patil, a Ford urologist and senior author of the study, said he could not say weight control would prevent a recurrence of cancer in men already diagnosed with the disease. But he said weight control "always is a good idea" to maintain good health.

The study analyzed weight measurements and tumor sizes in 3,327 men who had robotic prostate cancer surgery at the hospital in Detroit between October 2001 and October 2007.

Guidelines from the American Cancer Society suggest annual prostate exams for men beginning at age 50 but as early as age 40 for men who have a family history of prostate cancer.
