Naturally Boosting Immunity during Seasons

Each winter, and even in springtime, millions of aging adults gear up to battle microscopic invaders that can produce days and even weeks of coughing, sneezing and other symptoms. While over-the-counter drugs may help treat symptoms, people remain sick until their bodies’ natural immune system overwhelms the infection. Healthy immune function is not only critical to rapid recovery but also determines how resistant people are to microorganisms.

Encourage your body’s healthy immune response to a changing environment with nutrients, which promote the production of antioxidant enzymes that support the body’s natural immune defenses against free radicals. Vitamins and probiotics also help maintain a healthy immune system and may act as immune system boosters, as well as lifestyle choices, sleep and a healthy diet.
