Insomnia is something nearly all of us have experienced at some time in our life. It can be an acute or chronic problem, and can greatly impact the way we experience life. An acute bout of insomnia lasts from a single night to a couple of weeks, and is often from stress or anxiety about work, school, an upcoming exam or public speech, or due to a traumatic event. Chronic insomnia is a long term problem that has been on going for more than 6 weeks; it can have detrimental health consequences and is associated with serious medical conditions and inflammation in the body. Chronic insomnia may be caused by a medical or psychological problem, and it is important to have more severe health issues ruled out, such as sleep apnea.
