Gossip: ” 100 thousand why – why to become aware sleepily after the meal ” : After having a meal for advantageous digest, the hematic flow of digestion can increase, opposite, the hematic flow of cerebrum can decrease, so the person can feel dozy to become aware.
The truth: Make after the meal stranding is whole world people’s curious issue. Love has the American of turkey in the festival, with ” more lubricious ammonia acid contain in turkey ” will explain this phenomenon: Those who make us drowsy is turkey, the lubricious ammonia acid in turkey can synthesize the fade black element that has hypnotic effect inside body.
But, according to the data of American Ministry of Agriculture, the lubricious ammonia acid that contains in turkey and other and commonly used flesh kind, if the photograph such as chicken, beef is compared, do not have apparent difference. Turkey is so big eat hind is particularly Mondayish, do not have too big concern with lubricious ammonia acid apparently.
Offerring reductive view as to blood of the cerebra after the meal is slippery more. An overview middle finger 2004 goes out, this kind of view is contrary to with well-known neurophysiology criterion photograph, namely cerebrum regards the whole body as the most important organ, its blood is supplied should preferential assure, the hematic flow to digest and reduce cerebrum is unreasonable. Additional, the hematic flow of the cerebra after also making clear a meal without any evidence decreased, the hematic flow that has the brain after research discovers a meal even increased instead.
In fact, normal airframe also has distinctive mechanism to let keep of cerebrum smooth for blood really, the blood of other organ allocates even if to be changed somewhat, also won’t be opposite of cerebrum cause an effect for blood. For example when we move although sarcous offers blood to increase substantially, but the blood of cerebrum is stabilized for still maintaining.
Although turkey, blood is centered at gastric bowel to,not be tired matter makes after the meal, but tired phenomenon makes exist really after the meal, after scientists also think knowing after all is what reason caused a meal, make tired.
Eat so that jump over Rich, the drowsiness after eat is thicker
The researcher of medical center and Stanford university discovers Shengmataiao, cystic and contractive element (Cholecystokinin, CCK; Small intestine excretive a kind of peptide kind head / alvine hormone, small intestine and central nervous system have rich content, basically remove hormone and nerve to give qualitative effect) likelihood and postprandial drowsiness are concerned.
Researcher was monitored suffer inside body of the person that try the content of CCK, discovery is in 2 have meal hind to lift apparently inside the hour, fall after a rise begins after 2 hours. And measure a watch through Stanford drowsiness (Stanford Sleepiness Scale, SSS) show to enduring the investigation of drowsiness of the person that try, drowsiness begins to increase significantly after the meal, tend later gently.
Researcher makes think after the analysis to data, the drowsiness after the content of CCK and eat is both between the concern that existence positive involves. And, the CKK level that eats sheet of fast adipose food to suffer the person that try is higher, the drowsiness after eat is more intense also. The congener research of the drowsiness after other concerned CKK and eat also reachs similar conclusion.
Blood sugar is tall — appetite element is small — experimental rat was stranded
Additional, also have research clew, the blood sugar after eat is elevatory, appetite element content drops, the likelihood is to make tired another matter.
Appetite element (Orexin) , also call Qiu Naobi element (Hypocretin) , it is excretive of head issueing grave a kind of hormone, have appetite element – A and appetite element – B two kinds (or call Qiu Naobi element – 1 with next Qiu Naobi element – 2) . The hungry feeling of the content of appetite element and mankind and Morpheus are having immediate concern. When appetite element content low, the person can feel drowsy to mix do not consider motion. And moment of upland of appetite element content, the circumstance is met polarity, the person can become sober and active.
Have research discovery, when blood sugar concentration is high, can restrain the exudation of appetite element, appetite element content drops, experimental rat is shown Mondayish. And if absorb more protein, the amino acid that obtains from this can stimulate the exudation of appetite element, let experimental rat keep sober.
Postprandial drowsiness, the small law on evolution
Since satiate hind can produce drowsiness, the likelihood is the body hopes we are in satiate hind darling slow-witted move is not moved, such doing what profit is there?
On biology, the drowsiness after the scientist knows food exactly has how old value after all, why can be developmental process middleman and guarantor stays. The research of evolution psychology respect hints we, this mechanism may have the sense on evolution: Motion decreases after taking food, be helpful for the keep in storage of energy, the animal begins to search the energy that there is more to be able to be used when food again later.
Now, when we take food, compare normally quiet, and alimental stimulation can make a parasympathetic nerve relatively excited again. Excited parasympathetic nerve digests a function besides what can enhance us, promote draw nutrient material and compensatory energy besides, still can let our blood pressure drop, the heartbeat is decelerated, temperature is reduced, breath is decelerated, and these performance guide us easily to enter Morpheus.
But to modern, especially for the person with certain superfluous nutrition, the sense of the drowsiness after this eat is not great.
Conclusion: The rumor smashs. Drowsiness often reports for duty after the meal, but distributing to do not have what relation with lubricious ammonia acid with blood stream. So far, scientific group still fails to give out with respect to this one problem an unified, exact answer, the research of this respect also is undertaking all the time. Nevertheless, look at present, the machine rate of the drowsiness after hormone brings about eat with nerval adjustment is a few higher.
