You know the feeling. You feel overtired, burnt out and you may even be a little irritable. It might be time for a vacation. Summer is traditionally the time people travel for vacation because of the weather but sometimes just a "staycation" will do. A 2011 survey of over 1500 people by the American Psychological Association found that 1/3 of respondents feel tense or stressed our during their workday. Many people choose not to take vacation day for fear of their peers and their opinion of them as a hard worker. The truth is we all need a break. Stress affects our body systemically.
