 If you aren't taking at least two vacations a year, you're putting your health at risk. Women who vacationed less than once every six years were eight times more likely to develop heart problems versus those who vacationed at least twice a year. It was also found that employees who work 55 hours or more a week have a 35% higher risk of stroke. Kicking your feet up poolside can also help lower your blood sugar and improve good cholesterol levels. So remember that next time you're too afraid to take those vacation days.
