Guide To The Symptoms Of Stress

Irritability

One of the more apparent signs of stress is irritability. This form of agitation often precedes other symptoms, such as anger, mood swings, fatigue, and depression. The link between stress and irritability has been well documented, and researchers have identified different ways that stress can bring about these feelings. First, stress causes inflammation within the body that involves the release of cytokines. These are molecules that the immune system produces. Cytokines regulate inflammation, though they can also affect mood when they disrupt the natural circuitry between the brain and the nervous system.

In addition, stress leads to a sharp rise in cortisol and other hormones. An imbalance of these hormones within the body has been found to correlate with irritability. Irritability can cause a decrease in an individual's quality of life and can damage their working and personal relationships with others. Some studies have found links between increased irritability and more severe symptoms in patients suffering from various health conditions, such as heart failure.
