Biyolojik saat<\/p>\n
Biyolojik saat ya da sirkadiyen ritm, bedenimizi d\u00fcnyan\u0131n devinimiyle uyumlu hale getiriyor ve bedenlerimizin nas\u0131l i\u015fledi\u011fi konusunda b\u00fcy\u00fck de\u011fi\u015fiklikler yap\u0131yor. Neden gece uyumak istedi\u011fimizi a\u00e7\u0131klayan biyolojik saat, ayn\u0131 zamanda g\u00fcnl\u00fck ritmimizde ruh halimizi, hormon seviyelerimizi, v\u00fccut s\u0131cakl\u0131\u011f\u0131m\u0131z\u0131 ve metabolizmam\u0131z\u0131 etkiliyor. Biyolojik saat, d\u00fczenli olarak bedenimizin g\u00fcnd\u00fcz ve geceye uyum g\u00f6stermesini sa\u011fl\u0131yor. Bu nedenle saat dilimlerini \u00e7ok h\u0131zl\u0131 ge\u00e7mekten kaynaklanan bedensel ritm bozuklu\u011fu (Jet lag), d\u00fcnyayla senkronize olmam\u0131z\u0131 zorla\u015ft\u0131r\u0131yor. Biyolojik saatimizin k\u0131sa vadedeki de\u011fi\u015fimi bellek olu\u015fumumuzu etkilerken, uzun vadedeki de\u011fi\u015fimi ise tip 2 diyabet, kanser ve kalp rahats\u0131zl\u0131\u011f\u0131 gibi hastal\u0131k riskini art\u0131rabiliyor.<\/p>\n
