The holiday was created to honor the now-defunct Oscar the Grouch, a popular character known for his pessimism.
But according to therapist Julie de Azevedo Hanks, author of "The Burnout Cure: An Emotional Survival Guide for Overwhelmed Women," Grouching is not as bad it might seem.
Research has shown that adults who are pessimistic about the future live longer and are less likely to live with disability. In addition, people who are perceived as pessimists often use negative thinking as a motivational strategy.
“While they may be a drag to be around, they may actually be trying to improve themselves,” Hank says.
Whether you are a Grouch, know one or just want to celebrate for fun there are many different suggestions for how to commemorate this unusual holiday. While The Pueblo Chieftain suggests celebrating National Grouch Day by leaving your favorite grouch alone to wallow, Parenting Size Six recommends spending the day scowling at kittens, complaining about the sunshine, and barking "scram!" at anyone who asks a question.
