Cliff Arnall of Cardiff University dubbed the day "Blue Monday," and said his formula took into account miserable weather, mounting debt, the length of time since Christmas, failed New Year's resolutions, a lack of motivation and a need to take action. Advertisement However, he said those feeling gloomy should focus on staying active and fit to get over the hump, Sky News reported. He also agreed with a study done by the Community Service Volunteers group that said half of people who have volunteered for more than two years feel less depressed and 63 percent of 25- to 34-year-olds say they feel less stressed after volunteering. "Helping others can sometimes boost self esteem," Arnall said.
