The day that most people call in sick is on the 2nd of February, according to research from the insurance provider, Friend Provident. This day, this year also saw the highest amount of snowfall across the country, in more than a decade.

Factors, adding to the ‘National Sickie Day’ include the colder weather, economic gloom and post-Christmas blues.

The insurance provider conducted a report known as, ‘Britain under Pressure’ and predicted that around 30,000 people will call of sick on the 2nd of February.

In comparison to three years ago, the firm stated that more than 60 per cent of workers feel more prone to illness, more stressed and less healthy. Moreover, the reports stated that one in five people are sleeping less and one in three are worrying more.

The authors of the report stated that, the outcome of these health-related factors could cause further health problems ranging from headaches to clinical depression.

Mark Jones, head of protection at Friends Provident, said: "Our research shows that the UK's health is being affected by the credit crunch. As Britons feel increasingly unwell and stressed, action is needed. People need to make more effort to protect and care for themselves."

Findings from the report also stated that over half of Britons don’t exercise for at least 30 minutes, for five days a week – the Government’s recommended figure. While a third were found to either rarely or never eat the recommended five portions of fruit or vegetables each day, regarded an essential for good health.
