Irritability is a state of mind resulting in impatience or over-reaction to one's daily routine. This symptom may result from a wide range of life stresses. Some examples include:
* major changes in life (divorce, death, job stress) ,
* sleep deprivation,
* allergies,
* vitamin deficiencies,
* premenstrual syndrome, and
* seasonal affective disorder.

Irritability usually is a short-term symptom. When it is on-going, or severe, it may be caused by something more serious. Causes include digestive tract disease, neurologic problems, substance abuse, or mental illness.

Take steps to find the cause of irritability if it is a constant problem. Seek medical evaluation when it affects normal daily living. Signs include not sleeping or eating right, overuse of drugs or alcohol, or inability to do daily activities. Medical care can uncover and treat the underlying problem.

Counseling and stress management may reduce irritability. So can healthy habits. Try these:
* Stop or decrease the amount of caffeine and alcohol you drink.
* Get plenty of sleep.
* Exercise regularly.
* Take a relaxing long shower or bath.
* Enjoy a massage.
* Share your feelings with a trusted friend.
