Can Optimism Make You Healthy?

In a study of first year law students at the University of California at
Los Angeles, psychologists discovered students with positive attitudes and expectations had stronger immune systems and overall good health. Researchers drew blood from “declared optimists” and a control group. They then measured levels of key immune cells at the beginning of the semester. At that time there was no difference, but well into the stress-filled semester the optimists showed significantly higher levels of key immune cell activity than their less-than-positive counterparts. Keep smiling—you’ll live longer!
