What is stress in human body?


Stress is a natural physiological response to a perceived threat or challenge. When we experience stress, our bodies release a complex mix of hormones and chemicals that prepare us to respond to the threat or challenge.

The stress response, also known as the “fight or flight” response, can be triggered by a variety of physical, emotional, or psychological stressors, including physical danger, emotional trauma, work pressure, financial difficulties, relationship problems, and many other factors.

The stress response involves the activation of the sympathetic nervous system, which releases hormones such as adrenaline and cortisol. These hormones increase heart rate, blood pressure, and respiration, while redirecting blood flow away from the digestive and immune systems towards the muscles, brain, and other vital organs.

While short-term stress can be beneficial and help us respond to challenges, chronic or long-term stress can have negative effects on our physical and mental health. Chronic stress can lead to a range of health problems, including high blood pressure, heart disease, diabetes, anxiety, depression, and other mental health issues.
