Kafukufuku watsopano akuwonjezera kwambiri zotsatira za khofi. Mphamvu ya khofi, makamaka caffeine, pa physiology yathu komanso psyche yathu imawunikidwa. Kuyerekeza kunapeza kusiyana pakati pa kumwa khofi ndi kafeini m'mawa.
Khofi amakondedwa osati chifukwa cha kukoma kwake kokha, komanso chifukwa cha mphamvu yake yolimbikitsa - imathandizira kudzuka mwamsanga komanso kukhazikika bwino, pamodzi ndi zotsatira zina zopindulitsa.
Zotsatira zambiri za khofi zimachitika chifukwa cha chinthu chimodzi chomwe chimamwa mowa - caffeine. Zili ndi zotsatira zotsimikizika pazachilengedwe m'thupi, kukulitsa kutulutsidwa kwa dopamine ndikuwongolera kukumbukira. Caffeine imakhala ndi zotsatira osati pa biochemistry yathu, komanso pamalingaliro athu.
Pepala la sayansi linayang'ana kusiyana pakati pa kumwa khofi ndi kutenga mankhwala a caffeine mosiyana. Maphunziro a MRI achitidwa omwe amasonyeza mwachindunji zotsatira za ubongo. Zotsatira zikuwonetsa kuti khofi ndi caffeine zimachepetsa kulumikizana mudera linalake muubongo lotchedwa DMN, lalifupi la network mode default. Dera la DMN limagwira ntchito pamene malingaliro athu "akuyendayenda" ndikuchita njira zambiri zomwe zimatchedwa kusazindikira.
Kulumikizana kwa dera la DMN ku kugona kwathu kulipo - ntchito zambiri zomwe timachita m'mawa m'malo ogona zimachitidwa popanda cholinga chodziwika bwino, ngati kuti tikhoza kupita ku autopilot kudzera muzochita zomwe takhazikitsa. Pofika nthawi yomwe khofi yam'mawa imadyedwa, ntchito mudera la DMN imachepetsedwa. Ntchito yochepetsedwa imakhala ngati chizindikiro ku ubongo wathu kuti tikonzekere kutchera khutu ku malo athu ndi malingaliro athu.
Zotsatira za dera la DMN zimachitika chifukwa cha caffeine mu khofi, koma sizomwe zili mu zakumwazo. Lili ndi zinthu monga cafestol ndi kahweol, zomwe zimatha kuyanjana ndi zolandilira muubongo m'njira zomwe zimathandizira kuwonjezera mphamvu kapena kusintha malingaliro.
Kafukufukuyu akuwunika mwambo wakumwa khofi. Pali zotsatira zina zakumwa khofi zomwe zingakhale chifukwa cha zotsatira za placebo zomwe timadzipangira tokha - chikhulupiriro chamtundu wina kuti khofi imatipangitsa kumva bwino m'mawa ikhoza kukhala chinsinsi cha zotsatira zenizeni zolimbikitsa popanda caffeine kapena zinthu zina.
