Nws ua haujlwm li cas - cov kws tshawb fawb piav qhia.

Raws li cov kws tshawb fawb Kauslim, ua tsaug rau cov thom khwm, koj yuav tsis tsuas yog tsaug zog sai, tab sis kuj pw tsaug zog nruab nrab ib nrab teev ntev dua, vim tias koj yuav sawv tsawg dua. Txhawm rau kom nkag siab tias yog vim li cas qhov no tshwm sim, cia peb nkag siab ua ntej tias kev pw tsaug zog cuam tshuam li cas rau lub cev kub.

Thaum nruab hnub, lub cev tswj qhov kub ntawm li 37 ℃. Tab sis thaum hmo ntuj, tom qab 6-7 teev ntawm kev pw tsaug zog, lub hauv nruab nrab lub cev kub poob los ntawm yuav luag 1,2 ℃. Qhov kev poob qis no ua lub luag haujlwm tseem ceeb hauv neurobiology ntawm kev tsaug zog.

Qhov ceev koj lub cev qhov kub thiab txias, qhov ceev koj yuav tsaug zog.

Lub cev tswj hwm nrog kev pab ntawm cov hlab ntsha ntawm daim tawv nqaij. Thaum koj kub, lub hlwb qhia cov hlab ntsha kom nthuav. Yog li, cov ntshav sov los ntawm qhov nruab nrab ntawm lub cev kis mus thoob plaws lub cev thiab ua kom txias hauv cov txheej txheem. Thaum lub cev kub qis, lub paj hlwb, ntawm qhov tsis sib xws, muab cov hlab ntsha rau lub teeb liab, txwv tsis pub cov ntshav ntws mus rau saum npoo ntawm daim tawv nqaij.

Ces nws yog lub sij hawm yuav tsum nco ntsoov txog ob txhais ceg. Cov xib teg thiab ko taw yog lub cev ua haujlwm zoo tshaj plaws ntawm kev sib hloov cua sov. Lawv tsis muaj plaub hau thiab feem ntau qhib, tsis zoo li lwm qhov ntawm daim tawv nqaij. Cov kws tshawb fawb tau pom tias ua kom sov ob txhais ceg ua ntej pw hauv dej sov lossis nrog cov thom khwm pab kom cov hlab ntsha. Los ntawm qhov no, lub hauv nruab nrab lub cev kub poob sai dua thaum pw tsaug zog nrog ob txhais taw txias. Qhov no txhais tau tias koj yuav tsaug zog sai. Qhov sib txawv ntawm qhov kub thiab txias ntawm daim tawv nqaij ntawm qhov kawg thiab lub plab (los yog qhov sib txawv ntawm qhov kub thiab txias gradient) yog qhov taw qhia tseem ceeb ntawm qhov yuav ua rau tsaug zog sai dua.

Yog tias koj txhawj xeeb txog qhov kub dhau rau koj txhais taw, xaiv cov thom khwm ua los ntawm cov ntaub npuag ntuj.

Cov kws tshawb fawb kuj tau kwv yees tias cov thom khwm muaj cov nyhuv neurological. Lub hlwb muaj ib hom "thermometer" - tshav kub-sensitive neurons (WSN) nyob rau hauv lub preoptic cheeb tsam ntawm lub hypothalamus. Lawv kis impulses sai dua thaum lub hauv nruab nrab lub cev kub thiab qhov kub ntawm qhov extremities txawv ntawm ib leeg.

Raws li qee cov lus ceeb toom, qhov ntau zaus ntawm qhov tso tawm ntawm cov neurons no nce thaum pw tsaug zog thiab maj mam txo qis ua ntej lub cev sawv. Nws tseem tsis tau paub meej tias qhov ua rau yog qhov twg thiab qhov tshwm sim nyob qhov twg. Nws zoo li cov neurons no koom nrog kev xav ntawm kev pw tsaug zog, uas pab peb tsaug zog thiab tsis sawv thaum hmo ntuj. Hauv qhov no, ua kom sov koj ob txhais ceg ua ntej mus pw yuav ua rau lawv txoj haujlwm yooj yim dua.
