Unfortunately, these poisons do not only put stresses on our bodies, they put stresses on our minds as well. These physical forms of environmental stress put poisons into our brains as well, and can cause them to functions less effectively. Just as alcohol or drugs can affect ways that our minds work, these subtle poisons are also seeping into our brains and causing mental changes. In fact, receiving too many of these poisons can slow down mental processes without our noticing change. It will simply happen so slowly that we cannot notice difference.

In addition, one of most common causes of environmental stress is noise pollution. Anybody who lives in a large city is bombarded with a deluge of noise that can damage ears, numb senses, and cause a boatload of stress for our minds. With cars, busses, trains, factories, and people all screaming to be heard above din filling streets of modern city. These pressures on our brains and our eardrums are enough to shut mind down and send it into a cocoon of insensibility.

As well, simply being in a public place can cause us to have to deal with noise pollution. This is, of course, caused by infamous "cell yell". Anywhere we go in public, we must deal with people yelling into their mobile phones. This is not only annoying, but it is a form of environmental pollution. Listening to someone yell at a phone causes our minds stress and, through that, causes our bodies stress. They are annoying, and annoyance is a form of stress. Thus, we find ourselves stressed by something that is simply a fact of modern life.

Environmental stress occurs to us every day and we should be aware that it is happening. Obviously, we cannot be aware of it all time because to do so would probably cause us more stress just by simple worry. However, it is a fact of life while living in modern world and we should have presence of mind to know that environmental stress takes a toll on a body… and a mind.

Exercise stress tests are usually akin to exercising hard, but not strenuously. The person on treadmill is closely monitored and a doctor is on hand in case there are any problems. As well, person can stop test anytime if they do not feel right. However, it is best to let test run until it is finished, as it gives best idea of how well body is working.

A final kind of stress test is thallium test. These tests are usually administered in people who seem to have blockages in their circulatory system and blockages need to be located. Thallium tests are usually run in conjunction with an exercise stress test and, after person is done on treadmill, person is injected with a slightly radioactive thallium solution. Once thallium get into bloodstream, a special camera examines person's body in order to look for places where thallium, and thus blood, is not flowing properly. Thallium tests are not given very often, as they are mostly used when doctors know there is a blockage, but are not sure where to look for it. Obviously, some people cannot be asked to run on a treadmill and they are usually given a drug as a substitute in order to locate blockage.

There are a variety of stress tests available and your doctor is best person to talk to if you are interested in taking one. These tests are very valuable to check your overall health level and they provide a great deal of information that can be used to diagnose any problems or prevent them before they start. So if you are feeling effects of stress and you wonder if it is causing health problems, there are ways to find out what you or your doctor want to know.
