A mindful worker is a happier worker

The mental health benefits of mindfulness meditation include greater engagement in your daily activities and a more positive outlook — which can in turn improve your concentration and sense of well-being. But can mindfulness practice really help employees’ mental health? A recent study says yes. Workers participating in mindfulness training found they experienced less stress, anxiety, and depression; improved sleep; fewer aches and pains; and fewer problems getting along with others.

Low-nicotine cigarettes may help determined smokers cut back

A study examining the effects of low-nicotine cigarettes on smoking behavior yielded surprising results. The study volunteers who smoked the low-nicotine cigarettes actually smoked less and had fewer cigarette cravings than those who smoked cigarettes with a higher level of nicotine. Although more research is needed before we can draw any conclusions, it’s possible that very-low-nicotine cigarettes might be a way to mitigate the health dangers of smoking for people determined not to quit.

Overweight children are at risk for heart disease as adults

In a recent study of nearly 9,000 overweight and obese children and teens, doctors found that these young people had concerning blood pressure readings and worrisome cholesterol and blood sugar levels. In adults, such test results suggest a much higher risk for heart disease — so they are of particularly great concern in children. The good news is that with help and support, kids can lose weight — the results are a healthier, happier childhood and a greater chance of a healthier, longer adult life.

How well does calcium intake really protect your bones?

How much calcium do you really need for strong, healthy bones? The answer isn’t as clear as we once thought. Recent analyses suggest that neither dietary calcium nor calcium supplements reduce the risk of fractures. In the absence of a clear deficiency, it’s impossible to know how exactly much calcium a person needs. Ideally, you should get most of your calcium through food. Be sure you’re getting adequate vitamin D as well.

Why some parents don’t follow the “safe sleep” recommendations for babies

The very thought of losing a baby to sudden infant death syndrome (SIDS) is terrifying. Safer sleeping practices for infants have greatly reduced the number of babies lost to SIDS, but many parents are unclear on the reasons behind these recommendations and therefore often don’t follow them. The safest way to put your baby to bed is: on the back; in a crib, minus blankets, bumpers, and stuffed animals; and with a pacifier. Another critical factor is maintaining a smoke-free home and family.

“Not Again!” — When UTIs won’t quit at midlife

Hope Ricciotti, MD
Hope Ricciotti, MD, Editor in Chief, Harvard Women's Health Watch

Urinary tract infections (UTIs) occur in women of all ages. Physical and hormonal changes can leave women at midlife particularly vulnerable. No woman should have to put up with the inconvenience and discomfort of recurrent UTIs. Self-help measures can be effective, but if they don’t do the trick, see your doctor. He or she can identify and treat any underlying problems and recommend other strategies to keep UTIs at bay.

Treating unexplained infertility: Answers still needed

Jeffrey Ecker, MD
Jeffrey Ecker, MD, Contributing Editor

One of the most common treatments for unexplained infertility is ovulation induction, in which a woman takes drugs that will increase the number of eggs the ovary releases in the hope that at least one will result in a pregnancy. But when too many eggs are available for fertilization, the rates of high-risk multiple pregnancies go up. A recent study compared three drugs used for ovulation induction and found that the one more likely to result in a live birth was also more likely to result in a multiple pregnancy (twins, triplets, or more). The options for treating unexplained infertility remain less than ideal, but careful choices mean that the pregnancies that do result will be safer for moms and babies.

Tai chi can improve life for people with chronic health conditions

Julie Corliss, Executive Editor, Harvard Heart Letter

Tai chi has become popular in the United States in recent years, thanks in part to growing evidence for its many health benefits. This ancient Chinese exercise not only improves balance and flexibility, it may prevent falls, ease pain, and even help your heart. A recent analysis of 33 studies of tai chi suggests that doing tai chi can help older adults with common, long-term health conditions move about more easily and enhance their quality of life. The quality of life improvements may stem from the meditative, mind-calming aspects of tai chi.

Following low-risk prostate cancers before starting treatment becoming more common

Charlie Schmidt
Charlie Schmidt, Editor, Harvard Medical School Annual Report on Prostate Disease

Treatment decisions are complicated for men with low-risk prostate cancer that grows slowly. These cancers may never become deadly during a man’s expected lifespan. And there is no conclusive evidence showing that treatment in these cases extends survival. So cancer specialists have been leaning toward monitoring low-risk prostate cancer carefully and starting treatment only when it begins to spread. This approach was once used only in academic cancer centers, but new research suggests that this strategy is becoming more common in urology practices throughout the United States and other countries as well.
