Ushokoledi .. uwusizo emini .. uyingozi ebusuku

Ocwaningweni, olwanyatheliswa eminyakeni edlule, abacwaningi bathola ukuthi amandla amagundane elebhu okulawula ushukela wegazi ayehluka phakathi nosuku. Ukushintsha iwashi lazo lezinto eziphilayo, elibonisa ukuthi zilala futhi zivuka nini, kubangela ukuba bakhuluphale kakhulu.

Ngakho-ke, imiphumela yalolu cwaningo ichaza ukuthi kungani izisebenzi zasebusuku zinamathuba amaningi okuba nesifo sikashukela nokukhuluphala.

Lolu cwaningo luphinde lwaveza ukuthi “ukuphazamiseka kwewashi lezinto eziphilayo kubantu kuholela ekuphazamisekeni kwezinqubo ze-metabolic, okuholela ekukhuleni kwesisindo ngisho nokudla ama-kilojoule afanayo ekudleni kwethu, ngakho-ke inkinga ayikona nje kuphela lokho okudlayo kodwa uma udla. yidle.”

Kulolu cwaningo, umcwaningi uhlole ukusebenza kahle kwemizimba yamagundane ekugayeni ukudla phakathi namahora angamashumi amabili nane. Kuye kwaboniswa ukuthi ngezikhathi zasemini lapho amagundane engakwazi ukudla ngendlela evamile, awasabeli kahle ku-insulin, i-hormone etshela izicubu zomzimba ukuba zithathe ushukela egazini ukuze zisetshenziswe njengamandla, futhi ushukela oweqile ongasetshenziselwa amandla uyaguqulwa. emafutheni.

Lapho abacwaningi bephazamisa amawashi e-circadian amagundane ngokuwabeka ngaphansi kwesibani esibomvu esilufifi usuku lonke, amagundane aveza izimpawu zokumelana ne-insulin, okusho ukuthi izicubu zawo zomzimba azizange zisabele kumasiginali we-insulin ukuthi athathe ushukela, okuwenza akhuluphale. .

Ukumelana ne-insulin kuhlotshaniswa nesifo sikashukela nesifo senhliziyo kubantu.
