T-sheti yoyera ya thonje ndi batani lansalu-pansi ndizowoneka bwino zachilimwe. Koma kodi ndi nsalu iti mwa nsaluzi imene ingakupangitseni kuti muzizizira pa tsiku lotentha ndi lachinyezi?
Bafuta kapena thonje: Kodi ndi nsalu iti yomwe imakupangitsani kuti muzizizirira pakatentha kwambiri m'chilimwe?
2024-08-24
Tidalankhula ndi asayansi atatu a nsalu omwe amaphunzira za nsalu ndi ulusi pamlingo wa mamolekyulu kuti apeze yankho lotsimikizika, lasayansi lokhudza zovala zabwino kwambiri zomacheza masana achilimwe. Chigamulo chawo chimodzi: Linen adzakupangitsani kukhala ozizira.
Asayansi onse atatu adavomereza kuti ngati mukugwira ntchito kapena kuchita masewera olimbitsa thupi padzuwa, mungakhale bwino munsalu zopanga monga poliyesitala zomwe zidapangidwa ndi mankhwala kuti zichotse thukuta pakhungu lanu mwachangu momwe mungathere. Koma ngati kuvala kwamasewera sikuli koyenera, bafuta amapereka njira yabwino kwambiri yochotsera chinyezi ndi kutuluka kwa mpweya.
"Linen ndi yabwino kwambiri popereka chitonthozo," adatero Sundaresan Jayaraman, pulofesa wa sayansi yakuthupi ndi uinjiniya ku Georgia Institute of Technology. “Anthu amada nkhawa ndi mphepo yamkuntho. Linen ndiye ndinganene kuti mphepo yamkuntho chifukwa zonse zikuyenda bwino.
Chinyezi
Kukatentha, chida chachikulu cha thupi lanu chodziziziritsira ndicho thukuta. Pamene thukuta limatuluka pakhungu, limachotsa kutentha. Choncho m’nyengo yotentha, m’pofunika kuvala nsalu imene imathandiza kuti thupi lanu lichotse chinyezi.
"Chitonthozo chanu chimatsimikiziridwa ndi kuchuluka kwa chinyezi m'thupi," adatero Yiqi Yang, pulofesa wa sayansi ya nsalu pa yunivesite ya Nebraska ku Lincoln.
Mukufuna nsalu yomwe imayamwa mokwanira kuti ichotse chinyezi pakhungu lanu, komanso imalola kuti madziwo asungunuke mumlengalenga. Thonje ndi bafuta zonse zimayamwa kwambiri - koma thonje limasunga madzi pomwe bafuta amalola, malinga ndi Jayaraman.
"Ngati mukuyenda tsiku lotentha, lachinyezi mutavala malaya amkati a thonje, pofika kunyumba, malaya amkati amakhala atanyowa chifukwa akutenga thukuta lonse, koma alibe mphamvu yonyamula chinyonthocho kuchokera mu chovala chanu kupita kudziko lakunja," adatero. "N'chifukwa chake umakhala wopusa."
Mutha kuwona chifukwa chake thonje ndi nsalu zimachita mosiyana mukayika ulusi wawo pansi pa maikulosikopu, adatero Larissa Marie Shepherd, pulofesa wothandizira wa sayansi ya fiber ku Cornell University. Ulusi wa thonje, womwe umachokera ku timabotolo tating'onoting'ono ta njere za thonje, umawoneka ngati riboni ndipo umakonda kukhala wodzaza ndi kinks, zopindika ndi zopindika. Ulusi wansalu, womwe umachokera ku tsinde la mapesi aatali, a fulakesi aatali, amawoneka ngati ndodo za nsungwi ndipo amakhala owongoka komanso owuma.
"Mawonekedwe a riboni a thonje amatha kugwira madzi ambiri," adatero Shepherd. "Flakisi ndi yowongoka, kotero mulibe malo ambiri oti madzi atsekedwe mkati."
Mayendedwe ampweya
Thupi lanu limatulutsanso kutentha pamene mpweya wozizira umayenda pakhungu lanu - kotero pa tsiku lotentha, mumafuna kuvala nsalu yopuma.
Linen alinso ndi mwayi pano, Jayaraman akuti. Ulusi wake ndi wokhuthala kuposa wa thonje, motero nsalu za bafuta zimakhala ndi ulusi wochepa komanso mipata yambiri pakati pa ulusi. "Zikutanthauza kuti mpweya umadutsa mosavuta," adatero.
Koma kuchuluka kwa ulusi kumasiyana mosiyanasiyana kuchokera ku chovala kupita ku chovala. Shepherd adati muweruzire nokha nsalu. "Ngati mutha kuwona kuwala kudzeramo, ndiye kuti madzi ndi mpweya zimatha kulowamo," adatero.
Ubwino wina waukulu wa nsalu ndi kuuma kwake. Nsalu zansalu zolimba zimakhala ndi mawonekedwe ake bwino kuposa thonje, zomwe zimapangitsa kuti zovala za bafuta zichoke pathupi lanu pomwe zovala za thonje zimamatirira pakhungu lanu. Kusiya mpata wochuluka kuti mpweya uziyenda pakati pa zovala zanu ndi khungu lanu kumaziziritsa ndikuthandiza thukuta kusungunuka.
Mfundo yofunika kwambiri
Ngakhale nsalu ndi, mwasayansi, nsalu yozizirirapo kuposa thonje, sizinthu zokha zomwe muyenera kuziganizira posankha zovala.
Mwachitsanzo, kuuma kwa bafuta - komwe kumakhala kothandiza kulola mpweya kuyenda pakhungu panu - kumatha kuwasisita anthu molakwika. Wina akhoza kukhala womasuka ndi thonje chifukwa amamva bwino. "Chifukwa chake zimatengera zomwe mumakonda."
Kuuma kwa Linen kumapangitsanso kuti ikhale ndi makwinya, yomwe imafunikira kusita kwambiri - pokhapokha ngati mukufuna kupita kukawoneka mozungulira. "Makwinya amatha kupanga mawu owoneka ngati munthu wabwino, wofuna kuchita," adatero Jayaraman.
"Nthawi zina kusankha kokongola kumasemphana ndi chitonthozo. Zimangotengera zomwe zili zofunika kwambiri kwa inu," adatero Yang. "Koma ndine injiniya wamankhwala, mwatsoka sindikudziwa chilichonse chokhudza mafashoni."
