Stress, whether it is minor or major, alters the body's chemistry, changing the balance of hormones and making us more susceptible to catching diseases such as colds and flus. Higher levels of stress are associated with conditions such as insomnia, high blood pressure, tension headaches, anxiety, and depression. Natural support supplements include ginseng, GABA, Kava, B vitamins as well as massage, relaxation therapy, tai chi and yoga.
