Psychologists in Britain have said that the last full week of January is the most depressing time of year, and labeled next Monday "Blue Monday". Blue is a slang way of saying "unhappy".
    Mondays are generally seen as the worst day of the week because people feel annoyed and tired at having to go back to work after a weekend with a different sleep pattern.
    There are various reasons why more people feel depressed at this time of year. (29) Many people have unpaid credit card bills for the Christmas presents they bought,and pay day is often not until the end of the month.
    As the party season is over,people feel stressed because they have to go back to real life—work and commuting ; and they may be unhappy with their body image after parties full of alcohols, chocolates, and other food at Christmas time.
    People may have already failed in their New Year’s resolutions, such as giving up smoking. The bad weather in January can also contribute to people feeling fed up.
    (30) Some companies are taking this quite seriously and offering counseling for any staff who is feeling depressed. They hope that helping people as soon as there are signs of depression will avoid absence. Evidence shows that unreasonable managers who fail to contribute to their staff feeling fed up at this time can expect an uncooperative workforce.
    To avoid feeling blue next January,experts say that the best thing to do is to plan better next December. (31) Spend less on presents,eat and drink less over the festive period,go to bed earlier,and make more realistic New Year’s resolutions.
