Sleeping is not a cold room after a man

End beauty of life is an important aspect of married life, but in real life, many women complain about their sex life is not perfect.Most complaints that her husband fell down asleep after sex, beside his wife at this time completely ignoring the feelings and physiological needs.Thus, there are many women understand the men in the sexual life Why are you so selfish?

Fact, this is a misunderstanding.After sex, and fell down asleep not exist in the individual men, but a universal phenomenon, some scholars have called the room after the foreign syncope, its performance for the men shortly after the sex had significant fatigue, by the drowsiness to deep sleep, there's time and each individual were mixed.Previously thought, the body sex

Exertion fatigue may be the main reason men appear, but a recent study found that this point of view the lack of accuracy.An American survey of sexual life, sexual life, the average heart rate 120 beats per minute, while the daily life of the maximum heart rate can reach about 100 times per minute, if coupled with some minor activities (such as brisk walking, short distance cycling, etc.), heart rate 120 beats per minute or higher, that is, sexual life, physical strength is equivalent to the daily life of some manual labor, but not a performance caused such fatigue.Where is then the reason for it?

Recently, foreign scholars found in the penis erection process, the black level of quality has improved.Black is the quality of the material secreted in brain tissue, under normal circumstances, the peak secretion of sleep the night before, the main regulating body of sleep, gives rise to a sense of lethargy and thus promote human sleep.A few years ago, the United States has developed such synthetic drugs to promote sleep, the effect is very good, which explains the above-mentioned phenomenon.In the process of penile erection, this should only occur at night to sleep The rise in the quality of early appearance of black, equal to men in the beginning of sexual life to taking sleeping pills, along with some physical exertion, large whistling after sex sleep is not surprising.Therefore, women should not attribute it to her husband's indifference.

Need to be reminded that it is precisely because of this phenomenon is a physiological response, it must be avoided in daily life after a short time engaged in the sexual needs of highly focused attention, such as driving, etc., as a highly sleepiness were driving down the road, the danger is obvious.
