Being stressed can overload your immune system, making you more prone to cold sores, infections and illness. Heightened and/or sustained levels of stress and negative emotions can cause some skin conditions to flare-up or worsen – these include eczema, acne, hives, psoriasis and hair loss. Because, nerve fibers in the skin have connections to many organs and bodily systems, stress and negative emotions can trigger imbalances that can cause or exacerbate existing skin conditions, and even weaken your immune system. If you are experiencing a lot of stress or anxiety, consider relaxation therapy, yoga, exercise or other stress-busting techniques to boost your bodys defense system. Donot forget, a sensible diet helps too!
