Your lunch is a chance to get away from your work and to take some time out to de-stress and re-focus your mind.
And by taking regular rests throughout the day, this can help to improve your sleep quality too, according to Dr Nerina Ramlakhan, Silentnight's sleep expert.
She says: "Regularly seeking rest and recovery throughout the day is one of the most effective ways of improving sleep quality. Use the time to go for a walk, stretch, change channels mentally, drink a glass of water or eat a piece of fruit.
"Try to take a lunch break of at least 20 minutes every day. Avoid checking emails or surfing the Internet during this time."
And a recent survey by Crosse & Blackwell found that over 60% of Brits miss there lunch up to twice a week, with a shocking 8% not taking a break at all.
And why are we not taking our lunch?
The research revealed that we skip this important rest out of guilt and job insecurity.
The most likely to skip their lunch is 18-24, as they are more likely to want to look keen to superiors as 16% admitted to worrying they don’t look committed if they take a break.
And women were also found to feel guiltier than men for taking a well earned break.
However, we can see why some people don't want to go out at lunch as it can add up if you're buying something to eat every day.
According to the study, 25% of office workers in London spend an average of £6 a day on their lunch, compared to the national average of £3.30.
But even spending £3.30 a day can add up overtime. The minimum wage for over 25s is now £7.20 an hour, so for someone working your average 9 to 5 job, you're effectively spending more than a days wage on lunches each month.
Chris Wright, Marketing Director for Crosse & Blackwell said: “Lunchtime is an important part of the working day and a chance to refuel and recharge.
"We commissioned this report to better understand Britain’s lunchtime routines and how we can encourage people to take this much needed break during the day.”
Somebody else that wants to encourage people to take their lunch break is Carol Vorderman, who is backing a nationwide campaign to get British workers out walking for 20 minutes during their lunch.
The 'Walking Lunch' campaign is run by Westfield Health and wants to boost people's physical and mental wellbeing by simply encouraging them to take a walk every day.
Carol commented on the campaign, explaining why it's so important for everyone to take their well deserved break: "The great thing about walking is you can do it anytime, anywhere, it’s free, you get fresh air, and you don’t need to remember your gym kit.
"Having a ‘Walking Lunch’ is such a simple idea and I urge everyone to get walking.”
Fiona Lowe, Head of HR Development & Strategy from Westfield Health, also explained why walking can make a big difference to everyone's life, as the results from their survey showed the following:
"There is a great deal of evidence that prolonged sitting increases the risk of obesity but can also cause serious illnesses such as heart disease and Type 2 Diabetes.
"Many people notice their mood improves and enjoy a general sense of well-being [from taking a walk]."
