Shorter days and colder temps could have you singing (and feeling) the blues. Some people may even get SAD—seasonal affective disorder, a type of depression that usually happens during the colder, darker months.

But the winter doldrums are not inevitable. Here are ways to supercharge this season with cheer:

Op for Outside: Sunlight exposure keeps your vitamin D levels up, which is good for your happiness. 

Be a Social Butterfly: Don't put the freeze on your social life—make plans with friends and family.

Keep Moving: Nothing works faster to boost your spirits than a good sweat session. 

Embrace the Season: Enjoy the activities special to this time of year, such as shopping at holiday markets and decorating your living spaces.
