It's been said that creativity is a major source of meaning in our lives. It's a bridge that ties thinking and emotion, that ties human beings to each other.
Like music, it appears that art (and all kinds of creative activities) are good for our brains. A 2015 Mayo Clinic, for example, links participation in artistic pursuits (traditional arts as well as crafts) with greater cognitive strength as we age. Creativity also appears to enhance wellness. According to the Samuel T. Gladding, author of The Creative Arts and Counseling, creativity can also expand our horizons and help us to gain insights into our own thoughts while bringing us great joy and satisfaction.
The benefits of creativity extend to people with Alzheimer's disease or other dementias. Part of the attraction may be that arts and crafts appear to draw on many areas of the brain. In addition, creation offers communication alternatives along with the added benefits of joy in the process and personal accomplishment.
Creativity also provides opportunities for shared meaningful bonds. When we think back on special times, we often remembers imaginative moments shared with others: baking cookies, quilting, designing the train layout, making vacation plans. The projects required shared thought and cooperation... and arouse emotions that embed them in our memories.
Maybe this is what winter is for. :-)
