Kutheni abantu befuna ukulala?

        Esi sisihloko esidala kwaye esitsha kwaye akukho mpendulo yanelisayo okwangoku. Kwimihla yangaphambili, kwakucingwa ukuba luhlobo oluthile lokunqumama engqondweni, kwaye kamva kwakuthatyathwa njengokuphumla kwengqondo okwethutyana, okufana nokulala kwezilwanyana, okuluhlobo oluthile lokuphumla kwengqondo. "uqhawulo kunye nokungasebenzi" kwiiseli zemithambo-luvo. Ekubeni iteknoloji electrophysiological, abantu It ngokuthe ngcembe watyhila yayo "isigqubuthelo semfihlelo"

　　 Kuvela ukuba ubuthongo bomntu abuyinkqubo ye-passive kunye ne-static njengoko kwakucatshangelwa ekuqaleni, kubangelwa kuphela ukungena okuqhubekayo kweentlobo ezahlukeneyo zengqondo ngexesha lokudinwa okanye ukuvuswa. I-Polysomnography ifumene ukuba ukulala kwabantu yinkqubo ye-physiological esebenzayo ngamaxesha kunye nezigaba ezahlukeneyo.

        Ngokweempawu ze-electroencephalogram echaziweyo, intshukumo yamehlo kunye ne-electromyography, inokwahlulwa ngokurhabaxa ibe yi-eye ekhawulezayo yobuthongo obuDynamic (efinyeziweyo njenge-REM) kunye nobuthongo obungakhawulezileyo bamehlo (ofinyeziweyo njenge-NREM).

        Kwinqanaba lokulala le-REM, ukunyakaza kwamehlo okukhawulezayo nokungaqhelekanga kunokufunyanwa, ukuphefumla nokubetha kwentliziyo kunyuka, uxinzelelo lwegazi luyenyuka, kwaye ithoni yemisipha iyancipha; ubuthongo bokuhamba kwamehlo obungakhawulezileyo bunokwahlulwa kwakhona ku-1, 2, 3 4. Ngexesha lamaxesha amane, imisebenzi yombane yengqondo eqhelekileyo kunye neempawu ezifana ne-spindle yokulala kunye ne-amplitude ephezulu ecothayo imisebenzi yombane yengqondo inokubonwa ngexesha. Ukulala kwe-REM kunye nobuthongo obungeyo-REM benza umjikelo wokulala, malunga nemizuzu engama-60-90, malunga ne-4-7 imijikelo enjalo ngobusuku, abantu abaselula balala ubusuku bonke, ubuthongo be-REM bubalelwa kwi-20%-25%, kwaye -i-akhawunti yokulala ngokukhawuleza kwamehlo malunga ne-75% -80%.

        Uphononongo olongezelelekileyo lufumanise ukuba kwinqanaba lokulala le-REM, ukulala ngokuqhubekayo kuvelisa ukuvuswa kwexesha elifutshane, okuluncedo kumzimba ukuba uhlale uluphaphele utshintsho kwindawo engqongileyo, kunye nokwandisa iprotein synthesis kwiintsana nabantwana abancinci, kwaye kuluncedo gcina umsebenzi we-neurological kubantu abadala. Gqibezela, uthathe inxaxheba kuguquko kunye nokuqinisa inkumbulo. Kwinqanaba lokulala le-non-REM, kufumaniseka ukuba ukusetyenziswa kwamandla emzimbeni kuncitshisiwe, kwaye ukukhuselwa kweehomoni ezahlukeneyo zepituitary kuyanda, kwaye ukukhutshwa kwehomoni yokukhula kufikelela kwincopho kwinqanaba lesine, ngoko kunokuphelisa. umzimba' ukudinwa kunye nokubuyisela amandla omzimba.

Ngamafutshane, ukulala kubaluleke kakhulu kwimpilo yomzimba kunye nengqondo yomzimba womntu. Abantu bafanele balungelelanise ubomi babo ngokwenzululwazi, babe nocwangciso oluthe rhoqo, balale kamnandi yaye banandiphe ubomi obonwabisayo.
