“Bug\u00fcn d\u00fc\u015f\u00fcnmek i\u00e7in hava \u00e7ok s\u0131cak!” Aram\u0131zdan kim bunu son kavurucu g\u00fcnlerde en az bir kez s\u00f6ylemedi veya duymad\u0131?<\/p>\n
Bu, yayg\u0131n bir yaz ifadesi gibi g\u00f6r\u00fcnebilir, ancak bilim, termometre belirli s\u0131cakl\u0131klar\u0131 a\u015ft\u0131\u011f\u0131nda beynin bir t\u00fcr “enerji tasarrufu moduna” girdi\u011fine ve daha yava\u015f \u00e7al\u0131\u015ft\u0131\u011f\u0131na dair giderek daha fazla kan\u0131t topluyor.<\/p>\n
PLOS Climate bilimsel dergisinde yay\u0131nlanan yak\u0131n tarihli bir ara\u015ft\u0131rmaya g\u00f6re, s\u0131cak hava dalgalar\u0131 dikkat, haf\u0131za ve karar verme becerisine zarar veriyor, \u0130klim de\u011fi\u015fikli\u011finin sadece kalp i\u00e7in de\u011fil beynimiz i\u00e7in de bir sorun oldu\u011funu do\u011fruluyor.<\/p>\n
Ara\u015ft\u0131rmac\u0131lara g\u00f6re a\u015f\u0131r\u0131 s\u0131caklarda dikkat, haf\u0131za, konsantre olma yetene\u011fi ve karar verme h\u0131z\u0131 azal\u0131yor.<\/p>\n
Sinirbilimci Kimberly Meidenbauer, “Organizma so\u011fumaya ba\u015flad\u0131\u011f\u0131nda, fizyolojik kaynaklar\u0131n bir k\u0131sm\u0131 v\u00fccut s\u0131cakl\u0131\u011f\u0131n\u0131n d\u00fczenlenmesine y\u00f6nlendiriliyor” diye a\u00e7\u0131kl\u0131yor. Y\u0131llard\u0131r y\u00fcksek s\u0131cakl\u0131\u011f\u0131n beyin ve davran\u0131\u015f \u00fczerindeki etkilerini inceleyen Washington State \u00dcniversitesi’ndeki bili\u015fsel ve \u00e7evresel \u00e7al\u0131\u015fmalar.<\/p>\n
Mekanizma bilgisayarlar\u0131nkine benzer: S\u0131cakl\u0131k \u00e7ok y\u00fckseldi\u011finde, i\u015flemci a\u015f\u0131r\u0131 \u0131s\u0131nmay\u0131 \u00f6nlemek i\u00e7in performans\u0131 otomatik olarak azalt\u0131r.<\/p>\n
Benzer ko\u015fullar alt\u0131nda beyin bile daha karma\u015f\u0131k bili\u015fsel s\u00fcre\u00e7ler i\u00e7in daha az enerjiye sahiptir.<\/p>\n
“Son y\u0131llarda – Meidenbauer ekliyor – baz\u0131 analizler a\u015f\u0131r\u0131 s\u0131cakl\u0131\u011f\u0131n gen\u00e7 ve ya\u015fl\u0131larda bile bili\u015fsel i\u015flevlere zarar verdi\u011fini g\u00f6sterdi sa\u011fl\u0131kl\u0131 insanlar.”<\/p>\n
En pop\u00fcler \u00e7al\u0131\u015fmalar aras\u0131nda Harvard T.H. taraf\u0131ndan 2018 y\u0131l\u0131nda y\u00fcr\u00fct\u00fclen bir deney yer al\u0131yor. Chan Halk Sa\u011fl\u0131\u011f\u0131 Okulu, Boston’daki s\u0131cak hava dalgas\u0131 s\u0131ras\u0131nda bir grup lisans \u00f6\u011frencisini takip etti.<\/p>\n
Klimas\u0131 olmayan binalarda uyuyan \u00f6\u011frenciler, klimal\u0131 odalarda dinlenenlere k\u0131yasla bili\u015fsel testleri \u00e7\u00f6zmek i\u00e7in daha fazla zamana ihtiya\u00e7 duydu ve daha fazla hata yapt\u0131lar.<\/p>\n
“Bili\u015fsel performansta \u00f6l\u00e7\u00fclebilir bir d\u00fc\u015f\u00fc\u015f g\u00f6rmek i\u00e7in yaln\u0131zca birka\u00e7 g\u00fcn s\u00fcren yo\u011fun \u0131s\u0131 yeterliydi” diye belirtiyor. Meidenbauer.<\/p>\n
Bunun nedeni \u00f6ncelikle fizyolojiktir.<\/p>\n
Beyin, v\u00fccut a\u011f\u0131rl\u0131\u011f\u0131n\u0131n yaln\u0131zca %2’sini olu\u015ftursa da, v\u00fccudun mevcut enerjisinin yakla\u015f\u0131k %20’sini t\u00fcketir. D\u0131\u015f ortam s\u0131cakl\u0131\u011f\u0131 y\u00fckseldi\u011finde bu kaynaklar\u0131n b\u00fcy\u00fck bir k\u0131sm\u0131 v\u00fccudu normal s\u0131cakl\u0131kta tutmak i\u00e7in kullan\u0131l\u0131r.<\/p>\n
Bunun sonucunda terleme artar, cilde kan ak\u0131\u015f\u0131 artar ve kalp-damar sistemi \u0131s\u0131y\u0131 da\u011f\u0131tmak i\u00e7in daha fazla \u00e7al\u0131\u015f\u0131r.<\/p>\n
Bu, \u00e7ok fazla enerji gerektirir ve beyne daha az kaynak kal\u0131r. Beynin dikkati, haf\u0131zay\u0131, konsantrasyonu, mant\u0131k y\u00fcr\u00fctme ve karar verme yetene\u011fini s\u00fcrd\u00fcrmesi zorla\u015f\u0131r.<\/p>\n
