Umzi-mveliso wokulungisa imatrasi ukuxelela indlela yokukuvumela ukuba ulale ubala kobu busika

Ngokufika kobusika, iindawo ezininzi zokupholisa ubushushu behlabathi, imozulu ifinyeziwe. Ilanga ngumsebenzi wokuma kwe-ikhweyitha, iindawo ezisemantla nasezantsi emhlabeni zinokufumana iiyure ezixabisekileyo zokukhanya kwelanga. Ezi mpawu bubushushu obupholileyo kunye neentsuku ezimfutshane. . . Utshintsho kunye namaxesha onyaka, ukulala kwethu kunye nokuvuka kwethu ebomini emini. Ukunqongophala kokukhanya kwelanga kunye neempembelelo zokusetyenzwa komatrasi kunye notshintsho lwamaxesha onyaka kwimpilo yethu, ukulala kunye nokuvuka ubomi kunempembelelo. Ngokunyuka kwexesha elifutshane, uninzi lwethu lujongana namathuba amancinci okukhanya kwelanga, ibhayoloji yethu ye-circadian izinto ezimbalwa ezibalulekileyo zenzekile. Ilanga alinikezi kuphela izondlo ezixabisekileyo ezifana nevithamin D, ikwanceda ukulawula isigqi sethu se-circadian. Inceda imizimba yethu ukuba ifumane ilanga lakusasa ivule inqanaba lethu leeyure ezingama-24 zokusebenza ngosuku. Ngamanye amazwi, ilanga liyingqondo yethu yokuqalisa izinto, lixesha lokuvuka. Xa kungekho ilanga, amandla ethu onke abi, akakwazi ukuqonda xa kufuneka uvuke, kungenjalo kufuneka sizive sidinwe kakhulu. Ukunqongophala kokukhanya kukhawulezisa ukukhuselwa kwemelatonin kwaye kwenza imizimba yethu nengqondo zilale. Ukuze unqobe ukungabikho kwelanga lasebusika elibangelwa ukuphazamiseka kokulala, kufuneka usebenzise ngokupheleleyo oko unokukhanya kwelanga. Nokuba ilanga liphuma, iiyure ezimbini kuphela zokuqinisekisa ukuphuma ngaphandle kangangoko kunokwenzeka ngeli xesha. Xa uhamba okanye ngexesha lekhefu lekofu emsebenzini, nceda uthathe umnxeba osebenzayo, kwaye uqinisekise ukuba unokuqhagamshelana nelanga
