Dr. Pradeep Aggarwal    12-01-2017 Consult

An adrenaline rush is an extremely intense feeling. Adrenaline is a natural hormone that is produced by the body and secreted throughout the body when you undergo some type of traumatic experience. For instance, if you are attacked by a dog or you get into a fist fight, you will notice an energetic feeling that gives you the power and strength to either escape or to attack. Because of this, an adrenaline rush can be intense and can be used in order to help you out. There are a number of different symptoms that you will probably experience if you undergo an adrenaline rush. Here are just a few of the symptoms of adrenaline:

  1. Noticeable Increase in Your Strength
  2. No Feelings of Pain
  3. Heightened Senses
  4. Sudden Boost of Energy
  5. Increased Breathing
Detrimental Effects
An adrenaline rush can have detrimental effects on health. In people with heart disease, it can cause a weakening of the heart muscle, heart failure or a heart attack. It can also affect the brain in negative ways. Continuous heightened levels of stress hormones can lead to a shrinkage of the hippocampus, the brain's main memory center. Stress hormone stimulates the production of IL-1 beta, a cytokine, or signaling molecule, that creates inflammation in the hippocampus and prevents the formation of new neurons. IL-1 beta also binds to sites in the hypothalamus, pituitary and the hippocampus, the researchers found.

Beneficial Effects
While hyperactivity in the adrenal gland can have detrimental effects on health, mildly increased levels of stress hormones can have positive effects on the blood content of leptin, a protein that is produced in the body's white fatty tissue and that accelerates the growth of cancer cells, research says. While the blood content of leptin normally is directly proportional to the amount of fatty tissue in the body, stress hormones may play a role in regulating how much leptin the fatty cells produce. The less they produce, the slower cancer cells will grow.

Stopping an Adrenaline Rush
Typically, you body releases adrenaline only when you need it. However, if you are suffering from an extreme adrenaline rush, it's important that you try to calm yourself down. Monitor your breathing and look to take long, deep breaths to slow your heart rate and blood pressure down. Sit down and try to focus on what's happening as well. The trick is not to panic and to let the adrenaline rush wear off by relaxing. Once the adrenaline rush subsides, you can resume your normal activities.
