Imindeni enabesifazane abambalwa inesiqiniseko sokuthi ukuya esikhathini kuyavunyelaniswa futhi bonke baba nakho ezinsukwini ezimbalwa ezizayo. Kuyiqiniso yini ukuthi ukuya esikhathini kuyanamathela phakathi kwabesifazane noma yinganekwane?
Ithiyori yokuvumelanisa imijikelezo yokuya esikhathini iwukuthi ama-pheromones abesifazane ayaxhumana lapho eseduze, okubangela ukuba bathole isikhathi sabo ngesikhathi esifanayo. Ukuvumelanisa kwesikhathi kwaziwa nangokuthi "i-menstrual synchrony" kanye "nomphumela we-McClintock." Kusekelwe embonweni wokuthi lapho uthintana ngokomzimba nomunye umuntu osesikhathini, ama-pheromone ayathonyana ukuze imijikelezo yanyanga zonke iqondane.
Abanye besifazane baze bafunge ukuthi "abesifazane be-alpha" abathile bangaba yisici esinqumayo lapho wonke amaqembu abesifazane ethola i-ovulation nokuya esikhathini. Ngokweqile, abantu abasesikhathini bayakwamukela ukuthi ukuya esikhathini kuyinto yangempela eyenzekayo. Kodwa izifundo zezokwelapha azinalo icala eliqinile lokubonisa ukuthi kuyenzeka.
isayensi ayikusekeli
Ngo-2006, ucwaningo lwenze isimangalo sokuthi "abesifazane abavumelanisi imijikelezo yabo yokuya esikhathini." Lolu cwaningo luqoqe imininingwane kwabesifazane abangu-186 abahlala ngamaqembu endlini yokulala eChina. Noma yisiphi isikhathi sokuvumelanisa esibonakala senzeka, ucwaningo luphethe ngokuthi, sasingaphakathi kwendawo yokuhlangana kwezibalo.
Olunye ucwaningo olukhulu olwenziwa yi-Oxford University kanye nenkampani yohlelo lokusebenza lokulandela inkathi i-Clue lubhekane nokushayisana okukhulu kuze kube manje kuthiyori yesikhathi. Idatha evela kubantu abangaphezu kuka-1500 ibonise lokho Akunakwenzeka ukuthi abesifazane bangaphazamisa umjikelezo womunye wokuya esikhathini ngokuba seduze komunye nomunye.
Kodwa-ke, ucwaningo oluncane olusuka ku-2017 lugcina umqondo wesikhathi uphila ngokuphawula ukuthi amaphesenti angama-44 ababambiqhaza abahlala nabanye besifazane abanolwazi lwesikhathi. Izimpawu zenkathi, njenge i-migraine yokuya esikhathini, zazivame kakhulu kwabesifazane ababehlala ndawonye. Lokhu kungabonisa ukuthi abesifazane bangaba nomthelela esikhathini somunye nomunye ngaphezu kwesikhathi sokuya esikhathini.
Ithiyori ebusa kakhulu ukuthi iyi-a isu elithuthukisiwe phakathi kwabesifazane ukubambisana bodwa, bayeke ukuba uhlobo lwe-harem yendoda eyodwa ebusayo. Umqondo uwukuthi ukube abesifazane bebenemijikelezo evumelanisiwe, bazovunda bonke ngasikhathi sinye, ngakho-ke indoda ayikwazanga ukuzala nayo yonke. Awukwazi ukuphatha zonke izinsikazi ngesikhathi esisodwa, yingakho bekukholelwa ukuthi kuyindlela yokusebenzisana phakathi kwabesifazane. Nokho, kuwumbono nje ngaphandle kwesisekelo sesayensi.
Kungani kungenakufakazelwa?
Iqiniso liwukuthi ngeke sikwazi ukunquma ukuthi isenzakalo sokuvumelanisa isikhathi singokoqobo kangakanani, ngenxa yezizathu ezimbalwa.
Ukuvumelanisa lo mthetho kunempikiswano ngoba asazi ngokuqinisekile ukuthi i pheromones inkolelo-mbono esekelwe kuyo ingase ibe nomthelela lapho inkathi iqala. Ama-Pheromone ayizimpawu zamakhemikhali esizithumela kwabanye abantu abasizungezile. Basho ukukhangwa, ukuzala kanye nokuvusa inkanuko yobulili, phakathi kwezinye izinto. Kodwa ingabe ama- pheromone omunye wesifazane angabonisa omunye ukuthi sekufanele aye esikhathini? Akwaziwa.
Isikhathi futhi kunzima ukufakazela ngenxa yokuhleleka kwemijikelezo yokuya esikhathini kwabesifazane. Nakuba umjikelezo wokuya esikhathini ojwayelekile uthatha izinsuku ezingu-28, uqala ngezinsuku ezingu-5 kuya kweziyi-7 "zenkathi" yakho lapho isibeletho siphuma futhi sizizwe siphuma igazi, abantu abaningi abazitholi izikhathi ngaleyo ndlela.
Ubude bomjikelezo obufika ezinsukwini ezingu-40 busengaphakathi kwendawo yalokho "okujwayelekile." Abanye besifazane banemijikelezo emifushane enezinsuku ezimbili noma ezintathu kuphela zokopha. Lokho kwenza esicabanga ngakho "njengesikhathi sesikhathi" kube imethrikhi eqondile encike endleleni esichaza ngayo "isikhathi."
I-synchrony yokuya esikhathini ingase ivele ngenxa ye imithetho yamathuba ngaphezu kwanoma yini enye. Uma siba nenkathi yethu isonto elilodwa enyangeni futhi sihlala nabanye besifazane abathathu, kungenzeka ukuthi okungenani ababili bayoba nesikhathi sabo ngesikhathi esisodwa. Lokhu kungenzeka kwenza ucwaningo lube nzima ngesikhathi sokuya esikhathini.
