Stress is a part of life that is unavoidable. Pressures and deadlines at work, problems with your loved ones, bills to pay, holidays, and more are all sources of stress. Other less obvious sources are noise, traffic, crowds, bad weather, a new job, or many other things. Many people actually create their own stress.
Stress can create a breeding ground for illness.
Researchers have estimated that stress may contribute to as many as 80 percent of all major illnesses. These include cardiovascular disease, cancer, endocrine system disorders, metabolic problems, skin disorders and infectious disorders of all kinds. The body responds to stress with a series of physiological responses that include raised adrenaline levels, blood pressure elevation, accelerated heartbeat, and muscle tension. The increased production of adrenal hormones is responsible for most of the symptoms associated with stress. This is also the reason that stress can lead to nutritional deficiencies.
