Ha...h...itshizi! Ngaba nawe uyathimla? (Sternutation) Masithethe ngale nto!

Ha.....hh.......itshizi! Ukuba usandul' ukuthimla, mhlawumbi kungenxa yokuba kukho into engaphakathi empumlweni yakho ekukhathazayo okanye kukho into ekukhathazayo. Ukuthimla, ngokwezonyango okubizwa ngokuba yi-"Sternutation," yindlela entle umzimba wakho oyisebenzisayo ukususa loo nto icaphukisayo engaphakathi empumlweni yakho. Kufana "nenkqubo yokhuseleko" encinci emizimbeni yethu.

Kutheni sisithimla?

Ngoku, makhe sibone, kutheni sithimla? Ngamafutshane, kwenzeka xa ii-mucous membranes ezingaphakathi kwempumlo zethu zivutha. Zininzi izizathu zoku rhawuzelelwa:

• Amasuntswana othuli
• Impova
• I-dander yezilwanyana
• Umsi (njengomsi wecuba, umsi womoya ophuma emotweni)
• Iintsholongwane ezibangela izifo ezifana nomkhuhlane kunye neflu (iintsholongwane ezibandayo eziqhelekileyo)
• Ivumba elinamandla lezinye iziqholo okanye iikhemikhali
• Ukuphefumla izinto ezibukhali ezifana nepepile kunye nomgubo wetshili
• Utshintsho lobushushu ngequbuliso (umzekelo, ukusuka kwindawo eshushu kakhulu ukuya kwigumbi le-AC)
• Abanye abantu bayathimla xa bevezwa lilanga elikhanyayo ngequbuliso . Oku kubizwa ngokuba yi-"Photic Sneeze Reflex." Kuyamangalisa oko, akunjalo? Siza kuthetha ngaloo nto kamva.

Kwenzeka ntoni ngokwenene xa uthimla?

Khawucinge ngesuntswana elincinci lothuli olungena empumlweni yakho. Ngaloo mzuzu, 'ii-sensors' ezingaphakathi kwempumlo yakho ziyakubona oku. Ziyakubona zize zithumele umyalezo kwinxalenye ekhethekileyo yengqondo yakho othi, 'Nanku umntu ongamaziyo esiza, kufuneka simkhuphe ngokukhawuleza!' Oku sikubiza ngokuba 'ziziko lokuthimla'.

Inxalenye ekhethekileyo yobuchopho ebizwa ngokuba yi "Sneeze Center"

Eli `(Iziko Lokuthimla)` likwindawo yengqondo yethu ethi `(ingqondo)`. Ngokuchanekileyo, kwindawo ethi `(iMedulla Oblongata)`. Eli ziko likrelekrele kakhulu. Lifana ne-`CPU` yekhompyutha. Nje ukuba umyalezo ungene, unika 'ii-odolo' kwabanye bonke, esithi, `Kulungile, masiqalise ngoku! Wonke umntu makalungiselele!'

Zeziphi izihlunu ezinceda koku?

Ukuthimla akusiyo nje into yokufutha umoya ngempumlo. Yinkqubo enzima kakhulu. Kufana neqela elikhulu le-orchestra elidlala kunye. Kufuna izihlunu ezininzi emzimbeni wethu ukuze sisebenze kunye, ngaxeshanye, nangendlela ehlelekileyo.

• Izihlunu zesisu: Ezi zezona zinto zityhala ngamandla xa uthimla.
• Izihlunu zesifuba: Oku kuyanceda.
• I-Diaphragm: Le yimisipha emikhulu, ethe tyaba phantsi kwemiphunga yethu. Yimisipha esinceda siphefumle ngokuqhelekileyo. Ngaphambi kokuba sithimle, siphefumla nzulu, kwaye yimisipha esinceda sizalise imiphunga yethu ngomoya.
• Izihlunu ezilawula iintambo zelizwi: Ezi zikwabandakanyeka kwisandi esithi "ah-cheese" sokuthimla.
• Izihlunu ezingasemva komqala wakho: Ezi zibalulekile nakule nkqubo.

Khawuthelekelele indlela ezisebenza ngayo zonke ezi zihlunu kwaye zilungelelana ngayo kwimizuzwana embalwa, ngokusekelwe kumqondiso ovela kwi-"Sneeze Center"! Ayimangalisi na indlela esebenza ngayo imizimba yethu?

Imfihlo yokuvala amehlo akho

Owu, kwaye enye into! Ngaba wakha wambona umntu ethimla evule amehlo? Hayi, akunjalo. Xa sithimla, amehlo ethu ahlala evala . Lowo ngumyalezo ozenzekelayo ovela kwiZiko lokuThimla, oko kuthetha ukuba kwenzeka ngokuzenzekelayo. Abanye abantu bathi kungenxa yokuba besoyika ukuba amehlo abo aza kuphuma, kodwa oko akuyonyani yesayensi. Isizathu sokwenyani kukuba amehlo avalwa ngale ndlela ukukhusela amehlo kuxinzelelo oluphezulu lokuthimla. Kukwacingelwa ukuba kunceda ukuthintela iintsholongwane kunye nothuli ukuba lungangeni emehlweni.

Ikhawuleza kangakanani ukuthimla?

Ngoku jonga amandla ale nto. Xa uthimla, amasuntswana amancinci aphuma empumlweni yakho - amathe, loo nto yi-mucus - anokuhamba ukuya kuthi ga kwiimayile ezili-100 ngeyure! Oko kukhawuleza kunemoto kwiindlela zethu! Ungacinga ngesantya eso? Yiyo loo nto kubaluleke kakhulu ukusebenzisa ithishu okanye ukuthimla engqinibeni yakho xa uthimla. Ngaphandle koko, iintsholongwane zinokusasazeka kude nakude, kwaye unokosulela abanye.

Uphando olutsha ngokuthimla

Izazinzulu kwihlabathi liphela zifunda ngendlela enamandla ngayo ukuthimla kunye nendlela okusasazeka ngayo izifo. ULydia Bourouiba, umphandi kwiMassachusetts Institute of Technology (MIT), iyunivesithi edumileyo eMelika, kunye neqela lakhe benza uphando olukhethekileyo ngale nto.

"Basebenzisa imifanekiso ekhawulezayo ukurekhoda ividiyo yelifu lamathontsi aphumayo xa umntu ethimla. Emva koko, iBourouiba Research Group isebenzisa izibalo ukuhlalutya okwenzekayo kula mathontsi, ukuba ahamba umgama ongakanani, kunye nokuba ahlala ixesha elingakanani emoyeni. Ithemba kukuba olu phando luya kusinceda siqonde ngcono indlela izifo, ingakumbi izifo zokuphefumla ezifana nomkhuhlane oqhelekileyo kunye nomkhuhlane, ezisasazeka ngayo ngokukhawuleza."

Uphando olufana nolu lubaluleke kakhulu. Kuba ukuba siyiqonda kakuhle indlela isifo esisasazeka ngayo, kulula ukufumana iindlela zokusithintela. Ingakumbi ngeli xesha lobhubhane we-coronavirus, ukwazi izinto ezinje kubaluleke kakhulu.

Iingxaki ezincinci eziza nokuthimla nezinto ekufuneka uzazi

Xa sithetha ngokuthimla, sicinga ngezinye izinto ezincinci, akunjalo? Masibone ukuba ziyintoni na.

Ngaba kulungile ukuthimla?

Ngamanye amaxesha xa sikwindawo ebalulekileyo, njengentlanganiso okanye itempile, siziva ngathi siyathimla. Emva koko sibamba impumlo yethu size sizame ukuyimisa ngokuyigquma umlomo. Kodwa akunakwenzeka ukuba siyeke ukuthimla ngenkani.Ayilunganga kangako . Kuba, njengoko benditshilo ngaphambili, ukuthimla yinto ephuma noxinzelelo olukhulu. Ukuba uzama ukuyimisa, olo xinzelelo lunokutyhala ngaphakathi, lonakalise i-eardrum, lonakalise imithambo yegazi emincinci entanyeni, ngamanye amaxesha lubangele iingxaki kwi-diaphragm, kwaye kunqabile kakhulu, umthambo wegazi engqondweni unokuqhuma (ukuqhekeka kwe-brain aneurysm). Ngoko ke, ukuba uthimla, kungcono ukuyeke. Kodwa, ngentlonelo, ngendlela engabakhathazi abanye.

Uthini kakuhle?

Xa uthimla, kubalulekile ukunciphisa ukusasazeka kweentsholongwane kwabanye. Nantsi indlela yokwenza oku:

• Soloko usebenzisa itshefu okanye ithishu. Lahla ithishu kwisitya senkunkuma esivaliweyo emva kokuthimla. Hlamba kakuhle itshefu ngesepha uze uyiyeke yome elangeni.
• Ukuba awunayo ilaphu, thimla ungene engqinibeni yakho yangaphakathi. Oku kungcono kakhulu kunokuthimla esandleni sakho. Kuba sivula iingcango, sichukumise abanye abantu, size sitye ngezandla zethu. Ukuba sithimla ezandleni zethu, ezo ntsholongwane ziya kuyo yonke indawo.
• Emva kokuthimla , qiniseka ukuba uhlamba izandla zakho ngesepha ubuncinane imizuzwana engama-20 okanye usebenzise isicoci sezandla esisekelwe kutywala.

Kutheni ndithimla izihlandlo ezininzi zilandelelana?

Ngamanye amaxesha ukuthimla kube kanye akukususi ngokupheleleyo oko kusempumlweni yakho. Emva koko, umzimba wethu uthi, "Kulungile, masizame okunye!" size sithimle kwakhona, mhlawumbi amaxesha ambalwa. Kufana nokucoca impumlo yakho ngokupheleleyo. Isithathu okanye ezine ziqhelekile. Ukuba kuqhubeka ixesha elide kunoko, kunokuba yi-allergy. Kwimeko enjalo, licebo elihle ukubona ugqirha.

Ukuthimla okuneFotic

Nditshilo ngaphambili ukuba abanye abantu bayathimla xa bevezwa ngequbuliso lilanga elikhanyayo okanye xa bejonge ukukhanya okukhanyayo. Kuthiwa phakathi kwe-18% kunye ne-35% yabemi banale meko. Ibizwa ngokuba yi-`(Photic Sneeze Reflex)` okanye i-`ACHOO (Autosomal Dominant Compelling Helio-Ophthalmic Outburst) syndrome`. Kucingelwa ukuba yinto ye-`(genetic)` yemfuza. Oko kukuthi, yinto edluliselwa kwizizukulwana ngezizukulwana. Kucingelwa ukuba ibangelwa yi-`(cross-wiring)` encinci, oko kukuthi, ukudideka kwemiqondiso, phakathi kwe-`(trigeminal nerve)` ebuchotsheni, kunye ne-`(optic nerve)`, i-nerve evakalelwa kukukhanya emehlweni. Oku akuyongozi, kodwa kulungile ukulumka kuba ukuba kwenzeka ngequbuliso, njengaxa uqhuba, kunokuphazamisa kancinci.

Ngoko ke, ngamafutshane, izinto ekufuneka uzikhumbule

Kulungile, ngoko ke sithethe kakhulu ngokuthimla namhlanje, akunjalo? Ngamafutshane, khumbula oku:

• Ukuthimla yindlela yendalo yokuzikhusela esetyenziswa ngumzimba wethu ukucoca impumlo zethu.
• Ilawulwa yi-"Sneeze Center" esebuchotsheni, enomsebenzi onzima kakhulu wemisipha.
• Ukuthimla yinto enamandla kakhulu, ekhawulezayo.Ngoko ke, thimla ngokufanelekileyo (kwithishu, engqinibeni) ukuthintela ukusasazeka kweentsholongwane.
• Musa ukunyanzela ukuthimla ukuba kuyeke . Kunokulimaza umzimba.
• Ukuthimla elangeni (i-Photic Sneeze Reflex) yimeko eqhelekileyo yemfuza eyenzeka kwabanye abantu.
• Uphando olongezelelekileyo malunga nokuthimla luya kusinceda siqonde indlela izifo ezisasazeka ngayo.

Ngoko ke, kwixesha elizayo xa uthimla, khumbula ukuba ayisosandi nje 'setshizi', kodwa yinkqubo emangalisayo neyinkimbinkimbi eyenzeka ngaphakathi emzimbeni wakho. Kwaye ungalibali ukucinga ngabanye kwaye uthimla ngokukhuselekileyo, kulungile?
