Thupi la munthu limayendetsedwa ndi wotchi yamoyo mkati mwake momwe amagwirira ntchito tsiku ndi tsiku, monga momwe zimakhalira ndi nthawi yodyetsa komanso nthawi yodzuka ndi kugona. Njirayi imatchedwa circadian cycle kapena circadian rhythm, yomwe imakhudza kwambiri chimbudzi, kukonzanso maselo ndi kuwongolera kutentha kwa thupi.

Munthu aliyense ali ndi wotchi yake yamkati motero anthu adasankhidwa kukhala anthu am'mawa, omwe ndi omwe amadzuka m'mawa kwambiri ndikudzuka m'mawa, anthu amasana, omwe ndi omwe amadzuka mochedwa ndikugona mochedwa, ndipo nkhoswe.

Physiology ya kuzungulira kwa munthu

Nyimbo ya circadian imayimira nthawi yamaola 24 momwe zochitika zamunthu zimamalizidwira komanso momwe kugona ndi chilakolako chimayendetsedwa. Nthawi yogona imakhala pafupifupi maola 8 ndipo nthawi yodzuka imakhala pafupifupi maola 16.

Masana, makamaka chifukwa cha kuwala, cortisol imapangidwa, yomwe imatulutsidwa ndi adrenal gland ndipo mahomoniwa nthawi zambiri amakhala otsika usiku atagona ndipo amawonjezeka m'mawa kwambiri, kuti athe kudzuka masana. Hormone iyi imathanso kukulirakulira munthawi yamavuto kapena kukhala yopitilira nyengo yayitali, yomwe imatha kusokoneza magwiridwe antchito oyenda mozungulira. Onani zomwe hormone cortisol ndi yake.

Madzulo, kupanga kwa cortisol kumachepa ndikuwonjezera kupangidwa kwa melatonin, komwe kumathandizira kugona, kutha kupangidwa m'mawa. Pachifukwa ichi, anthu ena omwe amavutika kugona, nthawi zambiri amatenga melatonin nthawi yamadzulo, kuti athandize kugona.

Kusokonezeka kwa kayendedwe ka circadian

Kuzungulira kwa circadian kumatha kusinthidwa nthawi zina, komwe kumatha kuyambitsa kusokonezeka kwa tulo ndikupangitsa zizindikilo monga kugona tulo masana ndi kusowa tulo usiku, kapena kuyambitsa mavuto ena azaumoyo. Dziwani zovuta zomwe zimachitika mozungulira.
