stressihormooni

Stressihormooni is a Finnish term that translates to "stress hormone." It commonly refers to a group of hormones released by the body in response to perceived threats or challenges, activating the body's fight-or-flight response. The primary stress hormones are cortisol and adrenaline (epinephrine).

When the body encounters a stressful situation, the hypothalamus in the brain signals the adrenal glands to produce these hormones. Adrenaline is released rapidly, leading to an immediate increase in heart rate, blood pressure, and energy supply. Cortisol is released more slowly and helps the body manage stress over a longer period by increasing blood sugar and suppressing non-essential functions like the immune and digestive systems.

While the stress response is a vital survival mechanism, chronic stress can lead to prolonged elevated levels of stress hormones. This sustained exposure can have detrimental effects on physical and mental health, contributing to issues such as anxiety, depression, sleep disturbances, weakened immunity, and increased risk of cardiovascular disease. Understanding the role of stress hormones is crucial for managing stress effectively and promoting overall well-being.
