Workers with Access to Natural Light Sleep Longer and Better
Natural light in the workplace improves overall health, according to a new study in the Journal of Clinical Sleep Medicine. Researchers from Northwestern Medicine and the University of Illinois at Urbana-Champaign found that employees with windows received 173 percent more white light exposure during an average work day and slept an average of 46 minutes more per night. They also engaged in more physical activity and reported a better overall quality of life. “There is increasing evidence that exposure to light, during the day—particularly in the morning—is beneficial to your health via its effects on mood, alertness and metabolism,” said senior study author Phyllis Zee, MD, PhD, a Northwestern Medicine neurologist and sleep specialist, in a release. “Workers are a group at risk because they are typically indoors often without access to natural or even artificial bright light for the entire day. The study results confirm that light during the natural daylight hours has powerful effects on health.” Read more on environment.
Public Transportation to Work Linked to Healthier Weights
Public transportation should potentially be added to what we think of as “active commuting” modes because of its related health benefits, according to a new study on TheBMJ.com. People who go to work on public transportation tend to be thinner than people who drive their own cars, according to researchers from the London School of Hygiene and Tropical Medicine and University College London. The findings are based on data from 7,424 people in the United Kingdom on how much body fat they had and from 7,534 people on their body mass index. “It seems to suggest switching your commute mode—where you can build in just a bit of incidental physical activity—you may be able to cut down on your chance of being overweight and achieve a healthier body composition as well,” said study leader Ellen Flint, according to Reuters.

ACOG: All Pregnant Women Should Receive a Flu Shot
The American College of Obstetricians and Gynecologists is now recommending that all pregnant women, no matter how far along they are in the pregnancy, should be vaccinated against influenza. During the 2009-2010 flu season the immunization rate for pregnant women was 50 percent; prior to the 2009 H1N1 pandemic it was only 15 percent. According to the college, flu prevention is “an essential element of preconception, prenatal, and postpartum care” because of immune system changes during the pregnancy and the added need to protect the fetus. “The flu virus is highly infectious and can be particularly dangerous to pregnant women, as it can cause pneumonia, premature labor, and other complications, “ said Laura Riley, MD, chair of the College’s Immunization Expert Work Group, which developed the Committee Opinion in conjunction with the College’s Committee on Obstetric Practice. “Vaccination every year, early in the season and regardless of the stage of pregnancy, is the best line of defense.” Read more on maternal and infant health.
