You move more when travelling. You walk more frequently whether riding the subway or exploring the streets of a historic city or even visiting a museum. By swimming or laying on the beach, you get a high dosage of vitamin D from the sun, something that is very useful for your bones and also for your positive emotions. Outdoor activities associated with travel can lower risk of diabetes, lead to weight loss and reduce cholesterol level. Some medical experts recommend traveling once every six months for cardiovascular health and for the heart.
