Welcome Back To Science Recent. In today’s video, we’re embarking on a journey into the hidden world within us, unmasking stress, the silent puppeteer. Stress impacts us on a physiological level. When stress enters, your body initiates a chain reaction. From a rush of adrenaline to an increased heart rate, our bodies respond to stress in a complex and fascinating way.

How Stress Starts: The Alarm Bell
When a stressful event occurs, it’s like an alarm bell ringing in your brain. Your hypothalamus, the brain’s command center for controlling many bodily functions, releases corticotropin-releasing hormone (CRH). This is the green light for your body to kick into ‘fight or flight’ mode.
The Chemical Cascade: Adrenaline and Cortisol
CRH triggers the pituitary gland to secrete adrenocorticotropic hormone (ACTH). ACTH is like a VIP pass, signaling the adrenal glands to release adrenaline and cortisol. Adrenaline skyrockets your heart rate, blood pressure, and energy supplies. Meanwhile, cortisol curbs functions deemed nonessential in a fight or flight situation, freeing energy and focusing your body’s resources on the immediate stressor.
