Stres umum terjadi dalam kehidupan kita sehari-hari...
tetapi tau gak kalo ternyata stres itu banyak menimbulkan efek negatif bagi tubuh bahkan membuat tubuh kita rentan terhadap infeksi??
Stres ternyata mempunyai efek domino dalam sistem endokrin (endocrine system), yaitu sebuah sistem tubuh, berupa kelenjar yang memproduksi dan melepaskan sekresi yang disebut hormon (hormones), langsung ke saluran darah (kelenjar yang lain, seperti kelenjar ludah yang memproduksi air liur). Sistem endokrin yang terdiri dari kelenjar-kelenjar mendistribusikan hormon keseluruh tubuh. Beberapa kelenjar endokrin terlibat dalam menampilkan respons tubuh terhadap stres. Pertama, hipotalamus, suatu struktur kecil di otak, melepas suatu hormon yang menstimulasi kelenjar pituari didekatnya, untuk menghasilkan adrenocorticotrophic hormone (ACTH). ACTH, selanjutnya, menstimulasi kelenjar adrenal yang berlokasi di atas ginjal. Di bawah pengaruh ACTH, lapisan terluar kelenjar adrenal yang disebut korteks adrenal, melepas sekelompok steroid (misalnya, cortisol dan cortisone). Kortikol steroid ini (disebut juga kortikosteroid) merupakan hormon yang mempunyai sejumlah fungsi yang berbeda-beda dalam tubuh. Hormon ini mendorong perlawanan terhadap stres, membantu perkembangan otot dan menyebabkan hati melepaskan gula, yang merupakan tenaga dalam menghadapi stresor yang mengancam. Mereka juga membantu tubuh mempertahankan diri dari reaksi alergi dan peradangan (inflammation).
Cabang simpatis dari susunan saraf otonom (ANS) menstimulasi lapisan dalam dari kelenjar adrenal, disebut: medulla adrenalis, untuk melepas zat kimia yang disebut catechholamines-epinefrina (adrenalin) dan nonepinefrina (nonadrenalin). Zat ini berfungsi sebagai hormon setelah terlepas di dalam aliran darah Nonepinefrina juga diproduksi di sistem saraf dan berfungsi sebagai suatu neurotransmitter. Gabungan epinefrina dan nonepinefrina menggerakkan tubuh menghadapi stresor dengan meningkatkan kerja jantung dan menstimulasi hati untuk melepaskan persediaan gula, menjadi tenaga yang bisa digunakan untuk melindungi diri kita dalam situasi yang mengancam. Hormon-hormon stres yang diproduksi oleh kelenjar adrenal membantu tubuh menyiapkan diri mengatasi stresor atau ancaman. Apabila stresor sudah terlewati, tubuh kembali pada keadaan normal. Selama terjadi stres yang kronis, tubuh terus-menerus memompa keluar hormon-hormon, yang dapat menyebabkan kerusakan pada seluruh tubuh, termasuk menekan kemampuan dari sistem kekebalan tubuh yang melindungi kita dari berbagai infeksi dan penyakit.
Hindari stres sebelum terlambat..!!

Health....what is it???
First posting...
When I opened this blog, I very2 wanna share about How beautiful of my Indonesia...
but I think, Health is important to share too.....
healthy is number one, without that....i didn't know, how complicated this life...
Start with this, I just get this from my book, if you have other definitions,...it's better...
Definition of health...
health is a highly individual perception. Some people define health as the ability to carry out their normal daily tasks : A healthy women is able to go to work and accomplishes her usual tasks, A healthy youngster can go to school and play baseball at noon. other people consider themselves healthy only when they have vitality in their daily living and a feeling of wellness.
Meaning and descriptions of health vary with geography and culture. Health ang a highly industrialized nation such as the United State is quite different from health in some deprived nations. in the latter, skin lession may be considered normal and not a sign of all health, indeed, the absence of lessions may be considered uncommon.
In summary, there is no absolute definition of health. there is no certain knowledge of how to attain the ultimate level of health, nor can health itself be measured.
Factor influenching personal definition of health...
1. Developmental status
the idea of health is frequently related to person's level of development. The ability to conceptualized a state of health and the ability to respond to change in health are related directly to age.
2. Social and cultural influences
culture and social interaction also influence a person's notion of health. Each culture has idea about health, and often these are transmitter from parents to children.
3. Previous experiences
Experiences with health and illness also effect people's perceptions of health. Some people may consider a pain or disfunction normal because they have felt it before or often before.
4. Expectations of self
Some people expect to be functioning at a high level physically and psichosocially all the time when they are healthy.
