There is a "syndrome tiring sleep" - when a person wakes up in the morning tired Bashny.Net

Approximately 1% of adults are prone to sleep apnea. The two most common symptoms of sleep disorders - snoring (95%) and daytime sleepiness (90%). However, 40% of these people are also faced with the "tedious sleep." This means that they wake up just as or even more tired than when I went to bed.

According to Dr. Charles Pollack, "is how a person feels when waking up - no matter the time of day - depends on the stage of sleep in which it was time to wake up." If a person was in a stage of "REM sleep» (REM), and at the time woke up, he feels rested. However, if the "REM" disturbed sleep apnea or other condition, such as depression, airway obstruction with colds or even the influence of drugs, "people are likely to wake up in the phase of" slow wave sleep "- a deep sleep in which is not observed rapid eye movement" . So long as he does not fall upon awakening, and the phase of REM, it will "feel sleepy," even though he had slept enough.

Dr. Tom McCoy points out that a person needs "a full cycle of sleep to feel rested, and if your sleep is too short for this, the quality is likely to be low. So you can feel even more tired because missed the desired output from the cyclic sleep needed to feel refreshed and rested ».
