Our bodies need adrenaline because it is an essential part of our "flight or fight response," but according to Hormone, too much adrenaline can result in damage to your health.

Adrenaline is a hormone released by the adrenal glands, located at the top of each kidney. The reason adrenaline is released is in response to a number of situations, including fear, excitement, or a stressful situation, but this could also be when doing a number of activities, like skydiving or watching a horror film.

According to Healthline, when this suddenly happens it is often referred to as an adrenaline rush, and this typically starts in the brain, which processes the situation and determines if there is a threat, and then sends a signal to the adrenal glands, which respond by releasing adrenaline into the body. Most often, it is like a boost of energy and results in sweating, an increased heart rate, heightened senses, rapid breathing, increased performance, and a reduction in the ability to feel pain. Of course, having this response in a fight or flight situation is incredibly useful because it can help us respond appropriately in these circumstances.

However, adrenaline can be harmful when it is released too often, for example, when an individual is suffering from chronic stress and anxiety. Hormone notes that when adrenaline is released, it also releases glucose, and if there is no real danger then this energy has no use. This can result in a feeling of irritability. But it’s not just nervousness and irritability that is a cause, as the site also notes this can cause heart damage, high blood pressure, and even weight loss.

In addition to the aforementioned effects on health, an individual can also have issues sleeping and experience insomnia. According to Healthline, when someone is worrying, especially when lying in bed at night, it releases adrenaline and cortisol (the stress hormone) and when you're not using this energy, it will leave you restless.

Experiencing a release of adrenaline too often could also affect the ability to actually respond in situations where there is a real danger.
