It comes as no surprise to 27-year-old Matt Styles, who juggles a full-time job working on an arable farm with farming his own sheep, pigs and poultry near Whittlesey in Cambridgeshire.

It's not unusual for him to work 15 hours a day.

"There's this sort of stigmatised, almost toxic trait within agriculture that you have to be tough... and, you know, no one has bad days or bad feelings," he said.

"I've had to do a lot of sort of soul searching and figure out what I can do to cope with some of the pressures that I've faced.

"I've been presented with these feelings of anxiety and worry and sleeplessness and low moods and kind of thought: why am I feeling like this?"

A survey by the Farm Safety Foundation revealed that 92% of farmers under 40 believe poor mental health is the biggest hidden problem they face, up from 82% in 2018.

The charity has set up a campaign called Mind Your Head to encourage those who are suffering to seek help.

Stephanie Berkeley from the organisation said conversations about mental wellbeing must be normalised.

"We want to talk about it the same way we talk about going over on our ankle or having an injury in a five-a-side football match," she said.

"We all have mental health... We all need to look after it. Sometimes it's good. Sometimes it's bad, but it's okay also to talk about it."

Former Emmerdale star and Strictly Come Dancing champion Kelvin Fletcher bought his own farm last year in the Peak District and has seen first-hand just how tough it can be.

"Campaigns like Mind Your Head are so important if we're going to chip away at the stigma that surrounds mental illness in the industry," he said.

"It's time for farmers to start really looking after themselves as well as look after the livestock, the machinery, the land."

Mr Styles, who started the farm with his wife three years ago, has been helped by online therapy but also by talking to other farmers about how he's feeling.

"Often it can feel like you're just being surrounded by these bad feelings and that there's no way out, but there is always a way out and that could just be a conversation with somebody," he said.

"That other person may turn around and say: 'Oh, actually, I've been feeling a bit low as well. I didn't know who to turn to. I'm so glad you reached out to me'."
