Okokuqala, unake isikhathi sokulala kwakho. Kumuntu omdala, isimiso esamukelekayo semvelo, esilungiselela ukutholakala ngokugcwele kwamandla omzimba, kulinganiselwa ukuthi sibe amahora angu-7-8. Kodwa-ke, lesi sibonakaliso singumuntu ngamunye futhi singahlukahluka kokubili ezinkomba ezincane nezinkulu.
Okwesibili, ziphendule umbuzo: Ngabe ugibela nini? Kuze kube phakathi kwamabili noma ngemuva? Uma ungumlingisi wokubuka izinhlelo ze-TV ezisakazwa ngesikhathi esifushane kakhulu, zama ukulandela umthetho olula kanje: kufanele ulale okungenani isigamu sehora ngaphambi kwamabili. Ukushintsha okunjalo embusweni wosuku kuzosiza ekuqinisekiseni ukuphumula okuphelele, ngoba ukulala kuze kube phakathi kwamabili kubhekwa kunenzuzo emzimbeni kunobusuku.
Okwesithathu, omunye umthetho, okuyinto efiselekayo, uma kungenzeka, ukuba usebenzise zonke izinsuku: ukuhamba ngaphambi kokulala emoyeni omusha. Ukwaneliseka kwegazi lethu nge-oksijeni ngesikhathi sokuhamba kuhlinzeka nge-oxidation-ukunciphisa ukusabela okwenzeka emzimbeni wethu ngesikhathi sokulala. Lezi zimpendulo zikhuthaza ukuhlanganiswa kwe-adenosine triphosphate (ATP), ezosetshenziswa ngosuku lokukhiqiza amandla adingekayo ukuze kube nezinqubo ezihlukahlukene zokuphila. Uma usuke ukhathele kakhulu kangangokuthi awunawo amandla okuhamba eduze nepaki eliseduze noma isikwele, okungenani uzama ukuvula igumbi lokulala ngaphambi kokulala. Le nqubo izosiza ukuhlinzeka oksijini okwanele ekamelweni, okubaluleke kakhulu ukulala okuphelele.
Okwesine, umculi omkhulu wezindlu zokuhlala kufanele alandele le mithetho: endaweni yokulala akufanele ibe yizilimo ezingaphezu kwemithi. Iyini imiphumela yokwephula lo mthetho? Abesifazane abaningi, bekhumbula inkambo yesikole ye-botany, becabanga ngale ndlela: izitshalo zihlanganisa i-oksijeni ekwenzeni i-photosynthesis, ngakho-ke ngaphezulu ekamelweni lazo zonke izinhlobo zemifino, khona-ke kuyoba nokuqukethwe oksijini emoyeni. Ngempela, izitshalo zikhiqiza i-oxygen, kodwa le nqubo ye-photosynthesis ivele kuphela ekukhanyeni. Kodwa ebusuku, lapho kungekho ukukhanyisa, lezi zitshalo zizoqala ngokunamandla ukutholela umoya-mpilo emoyeni ukuqinisekisa izinqubo ze-oxidative emangqamuzaneni omzimba wazo. Ngakho-ke, emva kwephupho ekamelweni elinjalo cishe ngeke ukwazi ukuphumula ngokugcwele, cishe ekuseni uzozwa nomuzwa wokukhathala nokukhanda. Noma kunjalo - ngoba uzothola izibonakaliso zenkomo ye-oxygen ...
Okwesishiyagalolunye, ukuqinisekisa ukulala okugcwele kuzosiza ukushisa okuhle ekamelweni. Ungalali ekamelweni elishisayo kakhulu, ngoba kulokhu ulindele ukulala okuphansi. Kungcono ukuqinisekisa ukuthi kukhona umoya omuhle ekamelweni lokulala (lokhu kungafinyeleleka kalula ngokuphilisa kancane igumbi ngaphambi kokulala). Futhi uma ufuna ukufeza umphumela onzima, ungazama ukushiya iwindi elivulekile lonke ubusuku. Noma kunjalo, izinqubo ezinjalo kufanele ziqale ngenkathi efudumele. Esikhathini esizayo, ngokucima kahle, ungashiya iwindi elivulekile, ngisho nasesimo sezulu esibucayi.
Yonke le mithetho engenhla izosiza ukuqinisekisa ukuthi ulale ngokugcwele kanye nokuthola okusheshayo kokusebenza kahle.
