18 Jan Stress on the body
What is stress?
Generally speaking, stress means pressure or strain. Life constantly subjects us to pressures. In people, stress can be physical (as in having a disease), emotional (as in feeling grief), or psychological (as in being afraid).
Genes and things that happen to you early in life (such as child abuse or neglect), even when in the womb, can affect how you handle stressful situations, possibly making you more likely to over-react. Overeating, smoking, drinking, and not exercising, which are often reactions to being under stress, can add to the negative health effects of stress.
What is the stress response?
Allostasis is the process of how the body responds to stress, whether it is acute (short-term) or chronic(long-term). The best-known acute stress response is the “fight or flight” reaction that happens when you feel threatened. In this case, the stress response causes the body to release several stress hormones, such as cortisol and Adrenalin (also known as epinephrine), into the bloodstream. These hormones increase your concentration, ability to react, and strength. Also, your heart rate and blood pressure increase, and your immune system and memory are sharper. After you have dealt with the short-term stress, your body returns to normal.
Chronic or long-term stress, however, poses a problem. If you frequently face challenges, your body is constantly producing higher levels of stress hormones and does not have time to recover. These hormones build up in the blood and, over time, can cause serious health problems.
