Sleep cycle

Rapid eye movement (REM) is the part of sleep when a person dreams. It takes up approximately one fourth of the sleep time, usually in the early morning. The rest of the time is spent in non-REM (NREM) sleep which is further divided into 4 categories varying from light to deep. 

Sleep disorders disturb the normal sleep cycle, and the person does not rest properly at night. While most people have disturbed sleep occasionally, if they face this problem frequently, they are suffering from insomnia. A third of the adults in the US are suffering from insomnia at least once in their life. They are unable to get sleep and wake up repeatedly.

During sleep apnea, breathing stops for some time (usually several seconds) and will disturb the deep sleep. It will make the person very sleepy. Though most people are not aware, others in the room can detect the gasps, snorts and snores. 

When a person gets the urge to move his legs, it is difficult to get good sleep and this is called restless legs. 

When a person feels sleepy, despite resting at night, he may be suffering from narcolepsy. He may also have dreams because he enters the REM sleep mode.

Doctors will ask a patient suffering from insomnia to maintain a sleep diary with details of the sleep timings, food, emotions, medicines. A continuous positive airway pressure (CPAP) machine is used for treating sleep apnea, keeping airways open.
