According to a number of stress researchers, stress diseases are the major killers in North America and Europe today. Many allergies, too, are caused directly or indirectly by stress, and asthma is generally brought about through stress. Much heart disease, arterial disease, colitis, and ulcers are attributed to stress. Also, stress is considered to be a precondition which enables many forms of cancer to gain a foothold in the body.
Stress also breaks down our immunities to common diseases such as colds and influenza.
