Insomnia is repeated difficulty with initiation, maintenance, duration or quality of sleep. It may take individuals at least 30 minutes or more to fall asleep and they may get six or fewer hours of sleep on most nights. People may awaken several times during the night or experience a restless sleep; therefore, they feel unrested in the morning or experience excessive daytime sleepiness.
Insomnia can be grouped into primary and secondary insomnia. Primary insomnia is not caused by an underlying psychiatric or medical condition; however, secondary insomnia is caused by a medical condition such as depression or anxiety. Insomnia may be transient in nature, only lasting about a week, and is typically caused by an acute situational stressor. Insomnia may also be chronic in nature, lasting for more than one month, and is usually associated with more persistent stressful situations such as marital discord or death of a loved one.
Some of the common causes of insomnia include: alcohol, anxiety, caffeine, nicotine and stress. Get Tomorrow's Treatments Today if you qualify.
