Australian scientists have proved what we have known for a long time: holidays make us happy and live longer. Research has shown that a holiday can increase happiness and improve health for longer than the time you are away, reported the Daily Mail. Victoria University’s Dr Sebastian Filep said that motivations for travel, the experiences abroad and post-holiday memories all contributed to the three elements of happiness. These are positive emotions, a sense of purpose and a sense of involvement. Furthermore, being happy improves health and helps us live longer. “I see an opportunity for a greater connection between tourism and health where holidays become a more important factor in leading a healthy lifestyle,” said Dr Filep. “We know from studies in the US that experiencing positive emotions reduces the risk for cardiovascular disease, or that optimists live longer than pessimists.” It has been suggested that ‘holiday prescriptions’ could help beat depression.
