The average worker needs a holiday every 57 days, research has revealed. A study carried out among 2,000 Brits found just two months is all it takes before the tiredness sets in, performance at work starts to slide and we feel like we need to get away from the daily grind.
And while general fatigue was named as the main sign they are ready for a holiday, Brits also book a trip because they are sick of the weather or struggling to switch off from work.
Other warnings it's time to get away include losing sleep, arguing with your boss or colleagues and needing quality time with friends or family.
A spokeswoman for Virgin Holidays, which commissioned the research, said:
''Britain is a hard-working country and we all need to take a holiday now and again.
''And it seems many need some sort of getaway every two months to get their head back in the game.
''Just having a few days away from everything can really help you get over the stresses and strains of life in the workplace and even at home.
''And actually going away on holiday can be the perfect way to relax or unwind completely and catch up on some quality time with your partner or children.
''Not only does it allow you to have a break but it also means you can be refreshed and at your best when you get back to work.''
The study revealed that 54% of workers always book another holiday as soon as they return from their last one, simply because they need something to look forward to.
And 61% make sure they have at least one trip away or holiday booked in at all times.
An organised eight in ten even like to make sure they have a break or holiday at regular intervals throughout the year.
And almost a third of respondents plan their annual leave allowance at the start of each year, just to make sure they are going to be taking regular getaways over 12 months.
But 75% said that their work starts to suffer if they go too long without a holiday.
Almost two thirds of those said they lose interest in their work and don't try to go that extra mile, while four in ten said that their productivity goes down.
Making more mistakes, being less likely to skip lunches or work overtime to help out and not getting on as well with colleagues are other effects needing a holiday has on our work life.
Almost a third of stressed out workers have even been told they need to take a holiday by their boss or work colleagues.
Researchers also found that the ideal length of a trip away to allow them to relax is eight days, but more than one in ten admit that even when they do get away, they rarely manage to switch off completely.
45% still check their emails, 29% actually reply to emails and 22% even answer calls from the office or their clients and customers.
A spokeswoman for Virgin Holidays added:
''Checking emails while you're on holiday is so easy now - even when you're lying on a sunbed next to a pool.
''But a holiday is the one time where you can really recharge your batteries and forget about your day-to-day life.
''We're encouraging people to forget about work, relax and 'unleash your mojo' when you get away.
''If you don't, and you aren't feeling refreshed and ready to get back into it, you will soon need to book yet another holiday once you return to the office.''
A quarter of respondents also revealed that going on holiday has saved a relationship for them and 64% said it's the only real quality time they get to spend with their partner.
While one fifth of people have, or is planning to propose to their partner while they are on their travels.
