What is adrenaline?

Adrenaline is a hormone produced by the adrenal glands during high stress or exciting situations. This strong hormone is part of the system of acute stress reaction of the human body, also called the reaction of "fighting or flight". It works by stimulating heart rate, closing of blood vessels and dilating air passages, all of which work to increase blood flow to muscles and oxygen into the lungs. In addition, it is used as a medical treatment for some potentially life -threatening conditions, including anaphylactic shock. In the US, the medical community is largely concerned with this hormone as epinephrine, although these two terms can be used interchangeably.

Adrenal glands

Adrenal glands are located directly above the kidneys in the human body and are about 3 inches (7.62 cm). Adrenaline is one of several hormones produced by these glands. Together with Norepinephrine and Dopamine it is catecholamin, a relaxed group of hormon reaction to stress. These three hormones react with differentFor the body tissues and prepare the body physically respond to the situation causing stress.

Reaction of Fight or Flight

The term "fight or years" is often used to characterize the body's reaction to very stressful situations. It is an evolutionary adaptation that allows the body to respond quickly to danger. For example, widespread air passages allow the body to quickly get more oxygen into the lungs and increase physical performance for a short time. The blood vessels are downloaded in most of the body, which redirects blood towards the heart, lungs and the main muscle groups to help administer the reaction.

When a person encounters a potentially dangerous situation, the hypothalamus in the brain indicates the adrenal glands to release adrenaline and other hormones directly into the bloodstream. The body systems respond to these hormones in seconds, giving a person almost immediate physical support. Strength and speed increase while the body's ability to feelIT pain decreases. This hormonal increase is often referred to as "adrenaline rush".

side effects

In addition to noticeable increase in strength and procedure, this hormone usually causes increased consciousness and increased breathing. The person can also feel wireless, dizziness and experience changes in vision. These effects can take up to an hour, depending on the situation.

When there is no stress, but no real danger, one can be left restless and irritated. This is partly because adrenaline causes the body to release glucose, increases blood sugar and gives energy that has no drawer. Many people consider it beneficial to "process" the adrenaline rush after a particularly stressful situation. In the past, people have managed it naturally through fighting or other physical exertion, but a victory world, highly stressful situations often arise, which include small physical activity. Exercise can take advantage of this additional energy.

Although adrenaline can play a key role in PThe body is also causing harmful effects over time. Prolonged and elevated hormone levels can cause huge pressure on the heart muscles and in some cases can cause heart failure. In addition, it can cause the hippocamp to reduce. High levels of adrenaline in the blood can lead to insomnia and nervous nervous and are often an indicator of chronic stress.

medical use

The first synthesized in 1904 is adrenaline a common treatment of anaphylaxis, also known as anaphylactic shock. It can be quickly administered to people showing signs of serious allergic reactions, and some people with known severe allergies bear automatic injectors of epinephrine in an emergency. For these individuals, the dosage should be assigned to a physician with a license in advance and the jackets should be given according to how and where it should be administered.

Adrenaline is also one of the main drugs used to treat low cardiac output - the amount of blood pumps - and cardiac arrest. CanStimulate muscles and increases human heart rate. In addition, by concentrating blood into vital organs, including the heart, lungs and brain, it helps to increase the chances that the person will recover more fully.
