Mental Attitude: Secondhand Smoke May Cause Behavior Issues in Kids.
An analysis of data concerning more than 5,200 primary school students reveals that kids exposed to secondhand smoke while in the womb and/or at a young age have a greater risk for behavioral problems, especially emotional and conduct disorders. Study leader Dr. Isabella Annesi-Maesano wrties, “Our data indicate that passive smoking, in addition to the well-known effects on health, should also be avoided because of the behavioral disorders it may cause in children.”

Health Alert: Birds May Bring Exotic Ticks North.
The seasonal migration of some bird species may allow ticks to hitch a ride from Central and South America to the United States. Researchers found that 3% of migratory birds carried so-called neotropical ticks, which means birds likely bring more than 19 million neotropical ticks to the United States every spring. Fortunately, there is no evidence that any ticks have established permanent populations as exotic ticks can’t survive, reproduce, and spread in a Northern climate. However, some experts warn climate change may make it possible for these neotropical ticks to establish themselves in the United States in the future.

Diet: Vitamin D May Helps Women Build Muscle After Menopause.
According to a new report, vitamin D supplementation can significantly increase muscle strength and reduce the loss of body muscle mass in women years after menopause. Researchers found older women who received vitamin D supplements experienced a significant increase (+25.3%) in muscle strength, while those receiving a placebo lost an average of 6.8% of their muscle mass during the course of the multi-year study. The study also revealed that those who did not receive vitamin D supplements were nearly two times more likely to experience a fall. Dr. Wulf H. Utian, the Executive Director of The North American Menopause Society adds, “While this study is unlikely to decide the debate over Vitamin D, it provides further evidence to support the use of vitamin D supplements by postmenopausal women in an effort to reduce frailty and an increased risk of falling.”

Exercise: Do You Want to Live longer? Start Walking More and Sitting Less.
Replacing one hour of sitting each day with walking can decrease the chance of early death among seniors by 12-14%. Researchers also note that swapping one hour of sitting each day with standing results in a 5% decrease in the risk of premature death. On average, people over the age of 70 spend around 65-80% of their waking time performing sedentary activities, so substituting some of this time with standing or light physical activity could have a positive impact on their overall health.
