Reasons You Can't Sleep

A number of factors can come into play when a person can't sleep. A sleep problem exists if it takes longer than 30 minutes to drift off or when the sleeper wakes in the middle of the night, unable to fall back asleep.

Abnormal sleep patterns often include an imbalance of REM (rapid eye movement) and non-REM sleep
