New Study: Traffic Pollution and Heart Disease

Air pollution from automobiles isn’t only bad for the environment – it may also be bad for your heart. New research found that long-term exposure to fine particle matter from traffic pollution raises heart disease risk.

The specific form of traffic emission examined in this research is fine particle matter (PM), a type of pollution that consists of particles the size of about 1/100th of the width of a human hair. When these particles are inhaled, they can lodge in the upper airway and cause serious health effects. One of these health effects is an increased heart disease risk.

Melatonin and Diabetes Risk

Although much is known about type 2 diabetes, the exact cause remains a mystery. Many studies work to establish a connection between various factors and the development of the disease. One new study, published in the online journal JAMA, found a link between the secretion of melatonin in the bloodstream during sleep and an increased risk of type 2 diabetes.

Specifically, participants who secreted the least amount of melatonin in their bloodstream during sleep had double the risk of developing type 2 diabetes.

Melatonin, a hormone that helps control other hormones, is produced by the pineal gland in the brain and is highest at night, lowest during the day. It is essential for a good night’s sleep.

How Exercise & Computer Use Help Fight Memory Loss

We already know many of the benefits of exercise. One new study found, however, that when combined with computer use, exercise has the ability to protect against memory loss late in life.

Researchers studied participants who engaged in moderate physical activity (for example, brisk walking), and who used a computer on a regular basis. Results showed that these participants were 64 percent less likely to have mild cognitive impairment when compared to those who did not participate in computer use and exercise.
