Usuvele uthanda ukugibela ibhayisikili lasendlini ngenxa yokumpompa inhliziyo, ukushiswa kwekhalori, izinzuzo zomzimba ezinyakazisa umlenze, kodwa kuvele ukuthi ukuphotha amasondo akho kuwumsebenzi omuhle kakhulu womqondo wakho. Ucwaningo olusha oluningi luthole ukuthi ukuhamba ngebhayisikili kuthuthukisa indlela ubuchopho bakho obusebenza ngayo ngokwenza izakhiwo ezimbalwa ezibalulekile zibe zinkulu ukuze ucabange ngokushesha, ukhumbule okwengeziwe, futhi uzizwe ujabule kakhudlwana. (Bheka Izindlela Ezinhle Zokupompa Imisipha Yakho Yengqondo.)

Ingqondo yakhiwe yizinhlobo ezimbili zezicubu: Okumpunga, okune-synapses yonke futhi okuyisikhungo somyalo womzimba wakho, nento emhlophe, okuyindawo yokuxhumana, kusetshenziswa ama-axon ukuxhuma izingxenye ezahlukahlukene zezinto ezimpunga. Uma unento emhlophe kakhulu, kulapho ungenza khona ukuxhumana okubalulekile ngokushesha, ngakho-ke noma yini ekhulisa izinto ezimhlophe yinhle. Ucwaningo lwakamuva oluvela e-Netherlands luthole ukuthi ukuhamba ngebhayisikili kwenza lokho kanye, kuthuthukisa kokubili ubuqotho nokuminyana kwezinto ezimhlophe kanye nokusheshisa ukuxhumana ebuchosheni.

Udaba olumhlophe akusilo ukuphela kwesakhiwo sobuchopho esithinteka ngebhayisikili, noma kunjalo. Olunye ucwaningo, olushicilelwe kulo nyaka ku- Ijenali Yezinkinga Zesifo Sikashukela, ithole ukuthi ngemuva kokuhamba ngebhayisikili amasonto ayi-12, ababambiqhaza bathole okungaphezu kwamandla emilenzeni yabo - baphinde babona ukukhuphuka kwe-neurotrophic factor (BDNF) etholakala ebuchosheni, iphrotheni elibhekele ukulawula ukucindezeleka, imizwa nenkumbulo. Lokhu kungachaza ucwaningo lwangaphambilini olutholile ukuthi ukuhamba ngebhayisikili kuhlotshaniswa namazinga aphansi okucindezeleka nokukhathazeka. (Futhi kukhona lezi Zinzuzo Zempilo Yengqondo Eziyi-13 Zokuzivocavoca nazo.)

Ngeke nje uzizwe ungcono ngokwengqondo ngemva kokugibela, kodwa empeleni uzohlakanipha. Ukuhamba ngebhayisikili, kanye nezinye izinhlobo zokuzivocavoca nge-aerobic, kukhonjisiwe ukuthi kukhulisa i-hippocampus, engesinye sezakhiwo zobuchopho ezihlobene nememori nokufunda. Ucwaningo oluvela eNyuvesi yase-Illinois luthole ukuthi i-hippocampus yabahlanganyeli yakhula ngamaphesenti amabili futhi yathuthukisa inkumbulo yabo namakhono okuxazulula izinkinga ngamaphesenti angu-15 kuya kwangu-20 ngemva kwezinyanga eziyisithupha zokuhamba ngebhayisikili nsuku zonke. Ngokwengeziwe, abagibeli bamabhayisikili babike ikhono elikhulu lokugxila kanye nesikhathi esilinganiselwe sokunaka. Ngaphezu kwalokho, zonke lezi zinzuzo zibonakala ziphikisana nokulahlekelwa ukusebenza kobuchopho ngokuvamile okuhambisana nokuguga, njengoba ososayensi bephawula ukuthi ubuchopho babagibeli bamabhayisikili bubonakala buncane ngeminyaka emibili kontanga yabo abangazivocavoci.

"Ngokwandayo, abantu baphila ukuphila okungavamile. Nakuba sazi ukuthi [ukugibela ibhayisikili] kungaba nemiphumela emihle ezifweni zenhliziyo nesifo sikashukela, sithole ukuthi kungaletha ukuthuthukiswa kokuqonda, ukusebenza kobuchopho, kanye nesakhiwo sobuchopho, "kusho umbhali oholayo wocwaningo.

Ubuye wengeza ukuthi asikho isidingo sokuphuma konke ukuze kuthuthukise ubuchopho. Iningi lezifundo lakhombisa ukuthuthuka okuphawulekayo kwengqondo ngemuva kokuthi abagibeli bamabhayisikili begibele imizuzu engama-30 noma ngaphansi ngamandla aphakathi nendawo. Futhi imiphumela ibingaguquguquki noma ngabe abantu bagibela amabhayisikili abo ngaphakathi noma ngaphandle. (Bheka Izindlela Ezingu-10 Zokusuka Ekilasini Loku-Spin ukuya Emgwaqeni.)

Ukuxhumana okuqinile kwemizwa, isimo sengqondo esingcono, nenkumbulo ebukhali-ngaphezu kwempilo engcono yenhliziyo, ingozi ephansi yesifo sikashukela, kanye nezinga lomdlavuza. Ngazo zonke lezi zinzuzo, okuwukuphela kombuzo manje okufanele ube ngukuthi, "Liyaqala ngasiphi isikhathi lelo banga lesipina?"
