We often think of stress as a negative emotion, when in fact it is a necessary emotion. The human brain is wired in such a way that it is difficult to take action until it feels some level of stress. Yet, too much stress can cause serious physical and emotional consequences. For many people, stress is at its highest level at this time of the year. Several factors contribute to it: the challenge of getting your year-end work finished, the hustle-bustle of the holiday season, even the lack of sunlight in a Michigan December.
