Read the article and select the best answer. Article: How often do you go on holiday? Going on holiday makes you feel good while you're there-you gain the health benefits for months, new research shows. Jetting off to exotic destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress, it found. The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed. Experts say workers should always take their full holiday entitlement each year-as many as one in three don't-to get the benefits. The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with people who stayed at home and continued working. The average blood pressure of those on holiday dropped by 6% while the workers saw their blood pressure rise by 2% over the same period. The sleep quality of holiday-makers improved by 17% while that of the non-holidaymakers _ by 14%. The study also found the ability of vacationers to recover from stress--known as the stress-resilience test-improved by 29%. There was a 71% fall in stress resilience scores among workers. Test showed a fall in blood glucose levels, reducing the risk of diabetes, trimmer waistlines and enhanced mood and energy levels, with the effects sustained for at least 2 weeks after returning home. The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK's largest healthcare charity. Question: The author intends to tell us that _ .
