Monitor Your Mood It’s impossible to be in a good mood every day, even when you’re well. But how you feel emotionally will have an effect on how you physically heal, so it’s important not to give depression or anxiety the upper hand. In one 1998 study of dental students at Ohio State University in Columbus, small wounds that researchers created before a big exam took 40 percent longer to heal than identical wounds created during summer vacation. Each day plan activities that make you feel good, such as calling a cherished friend or drawing a bubble bath. If you find that you are down in the dumps or anxious day after day, seek professional help.
