As the holiday season approaches and the winter months settle in, many of us focus on protecting our physical health. We wash our hands more often, take vitamins, and bundle up against the cold. What is often overlooked, however, is how much mental health care can influence the strength of our immune system. Stress, worry, and emotional strain do more than weigh on the mind. They affect the body in ways that can make us more vulnerable to illness. Taking care of your mental health is not just about feeling better emotionally. It is also an important way to keep your body resilient.
