Ubulili Nezobuciko
Enye yezinzuzo eziyinhloko ze-physics kwezocansi yiqiniso, amandla okuphikisana, lapho sithola khona umqondo ocacile wenqubo uqobo. Nokho, ngaphezu kokuzijabulisa, sishisa futhi ama-kilocalories. Ososayensi bathola ukuthi ngesikhathi sokulala ngokobulili, okugcina isilinganiso semaminithi angu-30, umzimba udla cishe ngamakhilomitha angu-220, kanti ukuqeqeshwa kwamaminithi angu-20 ebhayisikheni yokuzivocavoca kuveza imiphumela ephansi kakhulu. Ngesikhathi esifanayo, izinkomba zingashintsha ngokuphawulekayo ekukhuleni, kuye ngezimo lapho ubulili buba khona. Isibonelo, uma ucansi:
Endaweni yomphakathi - ama-kilologori angu-412;
Ngaphambi kofakazi - 2.352 kcal;
Ubulili nomthandi ("lapho umyeni eya esitolo ngesinkwa") - 5687 kilocalories.
Yiqiniso, akukho okuhle ekusetshenzisweni okunjalo ngokweqile kwama-kilojoule, ngoba, njengoba kuvela, akugcini nje ukucebisana ubudlelwane nabathandekayo, kodwa futhi kuthinta impilo yomuntu siqu. Ngokwesibonelo, ososayensi nodokotela bathi abantu abaningi abasinda ekuhlaselweni kwenhliziyo balala nobulili nabathandi babo, futhi imbangela yokuhlukumeza isifo ngokwayo kwakuwukumesaba ukuchayeka. Kulesi simo, izinketho ezincane ezingasetshenziswa zingasiza. Isibonelo:
Ukuhamba okuqondile - 523 kilocalories;
Ku-limbo noma ngobulili kwibha enezingqimba - 1289 kcal;
I-group sex - 345 kilocalories ngomhlanganyeli ngamunye.
Ubulili kanye neKhemistry
Ngesikhathi sezocansi, inani elithile lamahomoni likhishwa emzimbeni womuntu, okubhekene nemizwa kanye nezinhlangano. Isibonelo, i-hormone yenjabulo noma injabulo yi-endophysein, ngenxa yokuthi umuntu uzizwa ejabule futhi ephazamise umuzwa wokucindezeleka.
U-Oxytocin unikeza umuzwa wokuthembeka futhi ukhishwa ngesikhathi se-orgasm kubo bobabili abalingani - kokubili amadoda nabesifazane. Ososayensi baye baqopha iqiniso lokuthi uma owesifazane ejwayele ukulala ocansini njalo, uthola injabulo futhi anganaki.
I-Testosterone iyaziwa ngokuthi i-hormone yesilisa, kepha ngesikhathi sokulala ngokobulili izinga layo egazini lika-wesifazane landa kakhulu (uma-ke, ukulala ngokobulili kwenzeka ngaphandle kokusebenzisa ikhondomu). Kanye ne-fluid seminal, iwela ezindongeni zesifazane wesifazane futhi igxila egazini. Ukungena okunjalo okubukhali ku-testosterone egazini lika-wesifazane kuthuthukisa isimo sakhe sengqondo, esingenakusho kubantu - sinesilinganiso se-hormone esinciphisa futhi indoda ilele ngokushesha ngemva kokulala ngokocansi.
Ngaphezu kwalokho, umsebenzi wobulili womuntu unciphisa emva kokuxhumana kocansi ngenxa ye-hormone dopamine, okusiza umzimba ukuba ubhekane nokucindezeleka, kanye ne-serotonin ne-oxytocin. Lawa mahomoni amabili anesibopho sokulala, futhi adala umuzwa wokukhathala. Kodwa kulaba besifazane ama-hormone enza umphumela ohlukile - banikeza amandla namandla.
Ubulili nesisu
"Isithende sika-Achille - sinalo wonke umuntu," - kusho ososayensi. Ngalo mqondo kusho ukuthi endaweni yesithende kukhona indawo eqinile evulekile. Ngakho-ke, uma uphumule futhi wenze ngendlela efanele kule ndawo, isibonelo, ukucindezela noma ukubhusa, ungathola i-orgasm. Futhi le-orgasm izohluka kakhulu kulokho ongakuzwa ngesikhathi sokushaya indlwabu noma ubulili obuvamile nomlingani wakho.
I-Orgasm iyimzwa emangalisayo futhi inqubo efana nesistimu yokugaya ingalawulwa. Lokhu kuqondiswa yi-reflex yokuzimela ye-system central yezinzwa. I-reflex ye-orgasm ingalandelwa emuva kwezigaba zakuqala zokuthuthukiswa komuntu, ngisho nasesibelethweni somama.
Okuthakazelisayo yiqiniso lokuthi "ukufeza i-orgasm akudingi izidakamizwa," kusho umlobi, intatheli uMary Roach. Utshela ngamacala lapho abesifazane bezwa i-orgasm, bebetha ngobunene amashiya abo. Futhi intombazane eyodwa yakwazi ukudala i-orgasm ngamandla okucabanga.
Ekuphetheni, singanezela ukuthi lezo zikole ziyalulaya njengekhemistri, i-anatomy ne-physics akuyona into enhle kakhulu. Into ebaluleke kakhulu ukusebenzisa isibonelo esihle.
