Stressihormoone

Stressihormoone, often referred to as stress hormones, are chemical messengers produced by the body in response to perceived threats or challenges. These hormones play a crucial role in the "fight-or-flight" response, a physiological reaction that prepares an individual to either confront a stressful situation or escape from it.

The primary stress hormones include cortisol and adrenaline (also known as epinephrine). When the brain detects a stressor, it signals the adrenal glands, located atop the kidneys, to release these hormones. Adrenaline is released quickly, causing immediate effects such as increased heart rate, elevated blood pressure, and a surge of energy. Cortisol, released slightly later, helps the body manage stress by regulating blood sugar, suppressing the immune system temporarily, and influencing mood and motivation.

While these hormones are essential for survival and adaptation in acute stressful situations, prolonged or chronic exposure to elevated levels can have detrimental effects on health. Chronic stress can lead to a weakened immune system, digestive problems, sleep disturbances, anxiety, depression, and an increased risk of cardiovascular disease. Understanding the role and impact of stress hormones is key to managing stress effectively and maintaining overall well-being.
