The adrenal glands produce hormones that help regulate the immune system, metabolism, and blood pressure. They also help the body cope with stress. In fact, the adrenals are known as “the glands of stress” and they enable the organism to deal with pressure and tension from every possible source, ranging from injury and disease to work and relationship conflicts. Resiliency, energy, endurance and life depend on their proper functioning. To maintain adrenal glands in good health, daily exercise and a diet rich in B vitamins can help. Sleep is also another important factor. Seven to nine hours of sleep in most people allows the adrenal glands to rest and rejuvenate.
