Stress miyangizga qanday ta'sir ko'rsatadi

Stress tamoman yomon narsa emas. U sportda raqobatga kirishganingizda yoki sahnadagi nutqingizda qo'shimcha energiya va diqqat jamlashingizda qo’l keladi. Ammo surunkali davom etsa, u sizning miyangizni o'zgartira boshlaydi. Madhumita Murgia surunkali stressning qanday qilib miya hajmi, uning tuzilishi va qay tariqa faoliyat yuritishi, genlaringiz qatlamigacha ta'sir eta olishi to'g'risida so'zlab beradi.

Ongoing stress does more than exhaust the mind; it actually changes the brain’s size, structure, and gene expression. High levels of cortisol, the stress hormone, shrink the prefrontal cortex and weaken memory and decision-making. Even nurturing or neglectful caregiving in rats can pass down stress responses for generations. Thankfully, exercise and meditation can reverse some of these damaging effects and help restore brain health.
