Toujours \u00e0 la bonne temp\u00e9rature<\/h1>\r\n\r\n\r\n

Tu sais certainement que l\u2019int\u00e9rieur de ton corps garde une temp\u00e9rature quasi constante 24h\/24. Et ce m\u00eame s\u2019il fait parfois tr\u00e8s froid ou tr\u00e8s chaud dehors? T\u2019es-tu d\u00e9j\u00e0 demand\u00e9 comment c\u2019est possible?<\/em><\/p>\r\n\r\n\r\n

Christiane Schittny<\/a><\/p><\/div><\/div>\r\n\r\n\r\n

<\/div><\/div>\r\n\r\n\r\n\r\n

Sans chaleur, rien ne va<\/h2>\r\n\r\n\r\n\r\n

Tous les humains ont deux zones de temp\u00e9rature. La temp\u00e9rature centrale qui r\u00e8gne dans la t\u00eate et \u00e0 l\u2019int\u00e9rieur du corps, dans le tronc en fait, varie tr\u00e8s peu. Pour que ton cerveau et tes organes internes \u2013 le c\u0153ur, le foie ou les reins \u2013 puissent fonctionner correctement, ils ont besoin d\u2019une temp\u00e9rature constante d\u2019environ 37 degr\u00e9s Celsius. Si cette temp\u00e9rature venait \u00e0 d\u00e9passer 42 degr\u00e9s ou \u00e0 tomber sous 32 degr\u00e9s, ta vie serait en danger!<\/p>\r\n\r\n\r\n\r\n

La temp\u00e9rature des extr\u00e9mit\u00e9s, en revanche, autrement dit tes jambes, tes pieds, tes bras et tes mains, varie. Elle d\u00e9pend entre autres de la temp\u00e9rature ext\u00e9rieure, dite \u00abenvironnementale\u00bb, et de ton activit\u00e9 physique. Les extr\u00e9mit\u00e9s servent \u00e0 \u00e9quilibrer la temp\u00e9rature de ton corps: si la temp\u00e9rature centrale est trop basse, les extr\u00e9mit\u00e9s seront moins irrigu\u00e9es en resserrant le diam\u00e8tre des vaisseaux sanguins. Il y a alors moins de sang qui circule et la chaleur reste \u00e0 l\u2019int\u00e9rieur du corps. \u00c0 l\u2019inverse, si la temp\u00e9rature \u00e0 l\u2019int\u00e9rieur du tronc est trop \u00e9lev\u00e9e, les vaisseaux des bras et des jambes se dilatent et la quantit\u00e9 de sang qui circule augmente. Quand une grande quantit\u00e9 de sang traverse des r\u00e9gions du corps plus fra\u00eeches, le sang peut refroidir et ton corps \u00e9vacue la chaleur superflue.<\/p>\r\n\r\n\r\n\r\n

As-tu d\u00e9j\u00e0 vraiment frissonn\u00e9?<\/h2>\r\n\r\n\r\n\r\n

Ton cerveau abrite un poste de commande important pour tout ton corps. On l\u2019appelle l\u2019hypothalamus. Un nom bien compliqu\u00e9! Cet hypothalamus r\u00e9gule un grand nombre de fonctions corporelles importantes comme la tension art\u00e9rielle, le sommeil et m\u00eame nos \u00e9motions. Il surveille aussi la temp\u00e9rature de l\u2019int\u00e9rieur du corps. Pour cela, il compare en permanence la temp\u00e9rature du moment et la temp\u00e9rature cible, \u00e0 savoir 37 degr\u00e9s.<\/p>\r\n\r\n\r\n\r\n

Si la temp\u00e9rature est trop basse, l\u2019hypothalamus veille \u00e0 ce que le corps produise plus de chaleur et la conserve. En frissonnant par exemple. Tes muscles travaillent alors \u00e0 plein r\u00e9gime et produisent beaucoup de chaleur. Si la temp\u00e9rature centrale est trop \u00e9lev\u00e9e, par contre, ton corps doit imp\u00e9rativement lib\u00e9rer de la chaleur pour \u00e9viter la surchauffe. C\u2019est ce qu\u2019il fait quand tu transpires. La sueur s\u2019\u00e9vapore \u00e0 la surface de la peau, ce qui la refroidit. Malin, non?<\/p>\r\n\r\n\r\n\r\n

Et \u00e0 quoi sert la fi\u00e8vre?<\/h2>\r\n\r\n\r\n\r\n

Tu en as s\u00fbrement d\u00e9j\u00e0 fait l\u2019exp\u00e9rience: tu es clou\u00e9(e) au lit, tu te sens tout flagada, tu as des douleurs ici ou l\u00e0 ou une vilaine toux \u2013 et pour couronner le tout, de la fi\u00e8vre! Franchement, tu t\u2019en passerais bien! Et pourtant, la fi\u00e8vre est importante. Sais-tu pourquoi?<\/p>\r\n\r\n\r\n\r\n

La fi\u00e8vre est en fait une r\u00e9action de d\u00e9fense de l\u2019organisme. Il lutte ainsi contre les microscopiques organismes \u00e9trangers responsables des maladies, comme les virus et les bact\u00e9ries, qui ont r\u00e9ussi \u00e0 entrer dans ton corps. Quand ta temp\u00e9rature corporelle d\u00e9passe 38 degr\u00e9s Celsius, c\u2019est que tu luttes contre une maladie. Mais pour \u00e9viter la surchauffe, tu commences
\u00e0 transpirer abondamment. Tu perds ainsi beaucoup de liquide et \u00e7a peut \u00eatre tr\u00e8s fatigant. Donc repose-toi bien et n\u2019oublie pas de boire beaucoup. Et tu seras certainement de nouveau tr\u00e8s vite sur pied!<\/p>\r\n\r\n\r\n","protected":false},"excerpt":{"rendered":"
