The study by Post Office Travel Insurance, UK has said that workers now require six holidays a year- i.e. a break every 62 days- to stay fresh and focused and avoid burning out.

Those who wait more than two months between holidays are more likely to become anxious, aggressive and ill, said the study.

“Workers really should take a break every few months otherwise they will burn out, which is bad for them and their employer,” the professor of organisational psychology and health at Lancaster University, as saying.

“People who fail to go on holiday are more likely to become anxious, aggressive and withdrawn. They may also develop aches and pains and struggle to sleep. Over-working depresses your immune system, making it more likely you will catch a cold or the flu.

“From the employer’s view, an employee who has not been on holiday will become less productive and more prone to mistakes,” he said.
