WHY STRESS MAKE THE BLOOD PRESSURE BE HIGH???


Stress is a term in psychology and biology, first coined in the biological context in the 1930s, which has in more recent decades become a common place of popular parlance. It refers to the consequence of the failure of an organism human or animal to respond appropriately to emotional or physical threats, whether actual or imagined.

Stress symptoms commonly include a state of alarm and adrenaline production, short-term resistance as a coping mechanism, and exhaustion, as well as irritability, muscular tension, inability to concentrate and a variety of physiological reactions such as headache and elevated heart rate.

Studies of female monkeys at Wake Forest University (2009) discovered that individuals suffering from higher stress have higher levels of visceral fat in their bodies. This suggests a possible cause-and-effect link between the two, wherein stress promotes the accumulation of visceral fat, which in turn causes hormonal and metabolic changes that contribute to heart disease and other health problems.

Even though many researchers have studied the link between high blood pressure and stress, there's no proof stress by itself causes long-term high blood pressure. It may be that other behaviors linked to stress — such as overeating, drinking alcohol and poor sleep habits — cause high blood pressure.

Researchers have also studied the link between heart disease and mental health conditions related to stress, such as anxiety, depression, and isolation from friends and family. While it's thought that these conditions may be linked to coronary artery disease, there's no evidence they're linked to high blood pressure. Instead, it may be that the hormones produced when you're emotionally stressed may damage your arteries, leading to heart disease. It may also be that being depressed or hopeless may cause self-destructive behavior, such as neglecting to take your medications to control high blood pressure or other heart conditions. With the other word, we can say that stress produce adrenalin hormon whom make the heart pump blood fastly, it cause the blood pressure be highly.
