The weather is heating up in Europe, and the first snow in two weeks is making it harder for farmers to plant corn and wheat.
But some people are taking a gamble.
In a bid to help them with winter food, some are going out and buying food to give to the hungry.
And for others, there is an extra element of risk.
A study published in the journal Nature this week found that people who were prepared to put themselves at risk were more likely to go out and buy food.
This is because they were more vulnerable to infection, and they were also more likely not to have access to emergency aid.
The researchers looked at more than 8,000 people, aged 18 to 77, and found that those who prepared for a long winter were more at risk of contracting an infection.
The risk was greatest for people who had been in the workforce for less than two months, those with higher levels of education and those who had not been in a job for six months.
The study was carried out by the Centre for Infectious Disease Research and Policy at University College London, and was published in Nature.
The key finding is that the risk was highest in the first two months after a long-term break from work, when people had already spent most of their time away from their work.
It was also highest in those who were already sick and those with less than a two-month work experience.
The research showed that people prepared for the long winter had the highest risk of infection, as well as the lowest levels of the two risk factors, education and working experience.
“It’s not just about health, it’s about a whole range of other factors that can make you more vulnerable,” Dr Jennifer Mathers, who led the study, told BBC News.
“So it’s not simply about risk.
We need to take action to prevent and control infection in the short term, which means reducing your risk of getting sick and increasing your chances of getting well.”
It’s not the first time researchers have looked at the impact of long-duration break from the workplace.
A recent study by the University of California, Irvine, found that workers who had just been out of work for a year or more had a lower chance of contracting pneumonia, than those who worked for six to 12 months.
It also found that working at home, rather than in the office, was the most effective way to prevent infections.
But the study was limited by its small sample size and limited to the United States.
So what does it mean for the people who are risking their health to help the people that they love?
The risk of infections was lowest in the third months after having a long break from being at work, as opposed to the first and second months, Dr Matherst told BBCNews.
But that could be because those who returned to the workforce after a year of absence have already been at work for most of the year.
And if they’re still at work they may not have been properly vaccinated, so the risk is still there, she added.
It could also be because people who have just returned to work are less likely to get vaccinated.
“There are all sorts of different factors that we can look at that could cause the effect we see in the UK,” Dr Msmith said.
She also said that the longer the break, the more people could be exposed to infections.
“We’ve shown in previous studies that people with a longer break from their jobs have been more likely than others to have a higher incidence of influenza and have been associated with more infections, and we’ve also shown that this is true for those people who return to work from the same time point,” she said.
“The reason is because these are people who don’t get to do the things that they’re doing when they’re not in their job.”
A number of studies have found that being away from work can also increase the risk of a range of conditions, including heart disease, cancer, strokes and dementia.
But Dr Mighs stressed that these are just a few of the many factors that could increase the chances of infections.
What about the environment?
Dr Maimart said that some of the risks were even more pronounced for people living in colder climates.
“When you’re working in colder conditions, your risk increases significantly,” she told BBC World Service.
“You may have a little bit of a risk of heat stroke or something else that might be a bit more severe.”
She said that many people who stay at home were also likely to have respiratory infections.
It’s been linked with poor air quality in certain parts of the country.
The climate in the Netherlands has warmed by 1C in the last 50 years, but Dr Maughs said that climate change could make that situation worse.
“In the Netherlands, we have a very, very high number of climate change-related events.
You have a much higher risk of those than you do in a place like the UK
