However, a problem can arise when nervousness occurs and there may not be an associated primary trigger. Some people can feel nervous for no reason at all. These people, unfortunately, can experience episodes where they feel extremely nervous — and this can occur without any particular reason. These symptoms fall under a condition called anxiety.

The person who feels anxious will find that their heart pounds faster than normal, their chest feels tight, they breathe rapidly, they feel that they cannot get a deep enough breath, their hands will tremble, they do not think properly, they worry continuously and these thoughts cause them to be pre-occupied to the point that it may even interfere with their daily life. when this occurs, it becomes a true anxiety disorder.

Anxiety disorders are very common. it has been estimated that more than 25 million Americans suffer from anxiety disorder. the main kind of anxiety disorders include panic disorder, phobias (fears), social anxiety, post-traumatic stress disorder and obsessive compulsive disorder.

These anxiety disorders can start in a person because of the lack of the body’s own defense to prevent anxiety. the body produces chemicals that prevent anxiety. Some people can inherit a lack of these chemicals. thus, it can be said that some anxiety disorders come from genetic causes. Also, environmental situations can cause anxiety. Stress, hard work and lack of sleep can lead to anxiety.

If a person believes he or she could be suffering from an anxiety disorder, talk it over with a doctor. there are many treatments available that help with this condition.

The first thing people should examine when they feel excessively nervous or anxious is what they are doing. If they are working long hours without rest periods, they should try to curtail that. If they are drinking a lot of caffeine containing drinks, they should try to reduce that. If they are not getting a good night’s sleep, they should try to correct that. If they are doing everything right and they still have these episodes of anxiety, then it is time to see a doctor.
