A free, easy way to help your health
News briefs
Want something simple to boost your health? Try looking on the bright side. A large observational study published online Sept. 27, 2019, by JAMA Network Open tied optimism to fewer heart attacks and a lower risk for premature death. Researchers combed through 15 studies that included almost 230,000 people who were followed for an average of 14 years. Being optimistic was associated with a 35% lower risk for cardiovascular events and a 14% lower risk for an early death, compared with being pessimistic. The findings don't prove that seeing the glass half-full causes better health, but many other studies have reported similar findings. "Optimistic people may have healthier habits, such as regular exercise and healthy diets; and they may be better at regulating their emotions in stressful situations, which could also contribute to lower levels of inflammation. But we need more research to confirm it," says Dr. Laura Kubzansky, a study author and co-director of the Lee Kum Sheung Center for Health and Happiness at the Harvard T.H. Chan School of Public Health.

Optimism: Good for your heart?
Research we're watching
People with a positive outlook on life seem to be less likely to experience serious heart-related problems, according to a review published Sept. 27 by JAMA Network Open.
The study pooled findings from 15 studies involving a total of more than 220,000 people. After a follow-up period lasting an average of nearly 14 years, researchers found that optimism was associated with a 35% lower risk of angina, heart attack, stroke, or death from cardiovascular causes. That benefit held even when they considered studies that took into account depression, physical activity, and other possible confounding factors.
Outrunning the risk of dementia
Even if dementia runs in your family, smart lifestyle changes can help you improve your chances of staying ahead of it.
There are many things you can change about your life, but unfortunately, your genes are not among them. For better or worse, you are dealt a specific genetic hand when you are born. But that does not mean you are defenseless.
Take dementia, for example. If this cognitive disorder runs in your family, new research suggests there are ways to perhaps avoid the same fate.
Can a dietary supplement help ease your depression?
It's not clear that supplements are effective, but some evidence is encouraging.
Some people are wary of taking antidepressants to treat their mild or moderate depression. They may not want to deal with the hassle of prescriptions, the costs, the potential side effects (such as sexual dysfunction), or the worry that medication treatment could mean an endless commitment.
Why dog owners seem to have healthy hearts
Research we're watching
Having a dog often means taking daily walks, a habit that helps stave off heart disease. But that might not be the only reason dog owners have healthier hearts, according to a new study.
The nearly 1,800 participants had no history of heart disease in 2013 when the study began. Researchers scored them based on the American Heart Association's "Life's Simple 7" factors: body mass index, diet, physical activity, smoking status, blood pressure, blood sugar, and total cholesterol. Then they compared the scores of people who owned any pet to those who did not own pets, as well as the scores of dog owners with owners of any pet or no pet.

Sexual and gender minorities face unique health risks
Memory problems and confusion are just the newest in a list of health problems that appear to disproportionately affect LGBT individuals.
Past research has shown that sexual and gender minority groups may be at higher risk for certain health conditions, including cardiovascular disease and mental health disorders such as anxiety and depression. A new study suggests that another condition — dementia — may also be on that list. Findings presented at the 2019 Alzheimer's Association International Conference showed that people who identified as a sexual or gender minority were more likely than other people to report worsening memory or increased confusion over the past year.
It's possible that some of the same underlying factors that affect risk of other diseases are playing a role in these reported cognitive changes as well, says Dr. Ole-Petter R. Hamnvik, an assistant professor of medicine at Harvard Medical School. "Almost any health outcome that you look at, you can find disparities in these groups. It's not just dementia," he says.
Take a breather
Simple breathing techniques may help you to better manage heart-related issues.
Maybe you're already in the habit of taking a deep breath to calm down when you're feeling fed up or frustrated. But a regular practice of focused breathing might offer even bigger rewards.
"Stress directly affects blood flow to the heart muscle, and any technique people can use to lower stress will benefit the heart," says Dr. Kimberly Parks, a cardiologist at Harvard-affiliated Massachusetts General Hospital. Some people turn to yoga, tai chi, or meditation for stress relief. But others aren't interested in trying those techniques. For them, a simple breathing practice may be more appealing, in part because it's easy, it's free, it takes just a few minutes, and it can be done anywhere at any time.
Women with post-traumatic stress disorder may be at higher risk for ovarian cancer
Research we're watching
Could a traumatic experience raise the risk of ovarian cancer? Researchers at the Harvard T.H. Chan School of Public Health and Moffitt Cancer Center found that women who remembered experiencing six or more symptoms of post-traumatic stress disorder (PTSD) had double the risk of later developing ovarian cancer, compared with women who had not reported PTSD symptoms. They were also more likely to develop a more aggressive form of the cancer. The researchers looked at data from more than 50,000 women who participated in the Nurses' Health Study II. Early in the study, women were asked to identify their most stressful life experience and any PTSD symptoms they had experienced following that event. Researchers then looked to see which of the women went on to develop ovarian cancer. The study, published Sept. 5 in Cancer Research, found higher cancer risk persisted even if a woman's PTSD symptoms had occurred decades in the past. Past animal research suggests that stress hormones may spur tumor growth.

Are you drinking too much alcohol?
Here's how to tell if you may have a drinking problem.
Alcoholic beverages are a "social lubricant." At holiday and other parties, bouts of excessive drinking can seem like part of the celebration. But here's something to think about as you raise your glass: drinking too much alcohol at a party — or at any time — can be a sign of alcohol use disorder (AUD).
What is AUD?
AUD is the umbrella term for problem drinking that stems from alcohol abuse or alcohol dependence. While both are marked by problems stopping or controlling alcohol use, they're not the same.
