How does it affect your overall health? And what can you do to manage your stress? A doctor should be able to diagnose the source of the stress-related depression and prescribe appropriate treatment.

Anxiety and panic attacks Like depression, anxiety disorders and panic attacks frequently have a stress-related connection. People who struggle with ongoing situations that make them feel uneasy may experience high levels of stress that can manifest in nervousness and fear, seemingly for an unknown cause. Through careful analysis, it can be discerned whether a stressful situation may be the cause for one of these disorders. If the disorders continue to occur or increase in frequency, it is a good idea to meet with a counselor or psychologist to deal with root issues.

Colds and viruses Physical illnesses caused by stress may be as common as the garden variety cold or a seasonal virus. People who are stressed often have immune systems that are not functioning properly.

Consequently, they can get sick faster and easier than they otherwise might. To alleviate stress that may be contributing to a prolonged cold or sickness, be sure to get plenty of rest, eat healthily and avoid worrying. Take care of your physical needs to keep your body resistant to germs, especially during the winter months.

This compression can reduce blood flow throughout the body and create problems like blood clots, poor circulation, or even strokes. In addition to dealing with the causes of stress with your doctor or a counselor, temporary relief may be found in a warm bath or shower, hot tea consumption, or mental relaxation therapy, such as daydreaming or positive imaging.

Do not let this advice substitute for a thorough medical examination and professional diagnosis, however. Systemic or local infections Ironically, mental or emotional stress can even delay physical healing of local infections, like a bug bite , or systemic infections, like food poisoning.

Inflammation in this context refers not to the sudden burst of activity you get following acute infection or injury — a protective attempt to deal with some form of harm to the body and to initiate the healing process — but to a low level elevation of chemical processes that are there all the time.

If Cohen is right, we now know how. Stress reduces the sensitivity of the receptors in effect chemical switches which are supposed to control the level of inflammation in the body. This possibility has actually been under consideration for some time. Cohen himself published some of the early work on glucocorticoid resistance. One study looked at parents of children with cancer: an extremely stressed group.

Back to the common cold. Cohen realised that data from two of his previous studies could be used to test this glucocorticoid resistance theory. Other research has shown that this acts as a surrogate measure of glucocorticoid resistance. The experiment revealed that prolonged stress is correlated not only with the likelihood of developing a cold, but also with higher levels of glucocorticoid resistance. In other words, the people whose receptors responded inadequately to the cortisol in their blood were the ones who got the colds.

In a second study, Cohen had made direct measurements of glucocorticoid resistance in a group of 79 subjects before exposure to cold viruses. The findings of both studies point in the same direction. What counts is not the amount of cortisol circulating in the body, but how much our cells react to it. So what of more serious disease? The real importance of the work, says Cohen, lies in its relevance to the many other conditions in which inflammation is a factor.

Cardiovascular disease, asthma, autoimmune disease, diabetes…The regulation of inflammation plays a big role in the progression of all of them. Steptoe agrees. And Phil Evans too joins the chorus of acceptance.
