Health Notes: A look at the latest medical studies and trends
Eat fish, be happy
According to a University of Pittsburgh study, there might be something fishy about your mood. Omega-3 fatty acids found in fish seem to affect areas of the brain associated with emotion. So, eating salmon is not only good for your heart; it may improve your mood as well. Previous research indicates that people with lower blood levels of Omega-3 fatty acids are more apt to have a negative outlook and to be more impulsive, while those with higher levels typically were more agreeable and less likely to exhibit a sour mood.
Walk away from that nicotine fit
Walking for as little as five minutes can help smokers fight nicotine cravings and quit smoking, according to a new study. Research published in the international medical journal Addiction showed that moderate exercise, such as walking, significantly reduced the intensity of smokers' nicotine withdrawal symptoms.
Laugh harder, live longer
Adults with a sense of humor outlive those who don't find life funny, according to the medical school at Norwegian University of Science and Technology, which tracked 54,000 Norwegians for seven years. Past research has shown that humor helps people cope with stress and keep a healthy immune system during stressful times.
