Two-thirds of adults will tell friends and family they’re “fine” over the holidays, even when they’re not, according to new research.

The study of 2,000 people found 34% are less likely to feel OK during the festive season — more than any other time of year. And about half of those surveyed believe others don’t want to hear their troubles, as it dampens the mood.

Were respondents to be asked by family how they are over Christmas dinner, 47% would keep the conversation light-hearted, believing it isn’t the right time to discuss heavy issues.

Commissioned by British snack food manufacturer Walkers to shine a light on the benefits of opening up and talking more, the study found 52% feel additional pressure to be happy during the holidays and pretend everything is OK.

Walkers and the British charity Comic Relief teamed up with TV/radio presenter and mental wellbeing campaigner Roman Kemp to inspire people to share, challenging the nation to give up the offensive four-letter “f” word — “fine” — this Christmas and beyond.

“As someone who has been open about their own battle with mental health and seen first-hand the devastating consequences of people bottling up their feelings, this is a campaign very close to my heart,” Kemp said in a statement.

“Christmas is an amazing time of year, but it’s also a very challenging time for a lot of people.”

The study found that Brits collectively proclaim they’re “fine” 213 million times every day, with a person typically saying it four times over a 24-hour period.

Some 87% confessed to saying they’re “fine” on autopilot when asked how they are — without even thinking about how they actually feel.

Money worries and current events were cited as the topics most likely to get people down.

The research, conducted by OnePoll, also revealed the top barrier to giving open and honest answers is that “it’s easier than explaining why you’re not fine,” along with not wanting to detail their feelings.
