Insomnia is a sleeping disorder that affects millions of individuals worldwide. Research has linked insomnia to high blood pressure, congestive heart failure, diabetes and other medical issues.

Not only does insomnia cause sleepiness during the day, it has been linked to deeper problems such as high blood pressure, congestive heart failure, diabetes and other ailments.

Insomnia can fluctuate throughout one's life and can be somewhat difficult to diagnose due to the variations of the disorder. The American Academy of Sleep Medicine has developed 11 variations of insomnia.

Insomnia is characterized by difficulty falling and/or staying asleep. Insomnia can be caused by many different factors including anxiety, medications, stress, caffeine, overeating before bedtime or a change in one's life.

Many people are unaware that they are suffering from insomnia, but there are a few common symptoms:

• Difficulty falling asleep
• Waking up often during the night and having trouble going back to sleep
• Waking up too early in the morning
• Feeling tired upon waking

There are two classifications of insomnia: primary insomnia and secondary insomnia.

Primary insomnia occurs when a person is having sleep problems that are not directly related to any other health condition or problem.

Secondary insomnia occurs when a person is having sleep problems because of something else, such as asthma, depression, arthritis, cancer or heartburn.
