Noradrenaline/Norepinephrine
Noradrenaline, also known as norepinephrine, is a chemical that acts both as a hormone and a neurotransmitter in the body. It plays a vital role in the fight-or-flight response, increasing alertness, arousal, and reaction time. Noradrenaline also aids in mood regulation and helps sustain blood pressure by narrowing blood vessels.
Description
Testing noradrenaline levels can be beneficial for individuals showing symptoms of certain adrenal gland disorders, such as pheochromocytoma. It’s also useful for those with unexplained fluctuations in blood pressure or heart rate, as well as people experiencing chronic stress, anxiety, or depression.
- Too Low: Depression, lack of focus, fatigue, and low blood pressure.
- Too High: Anxiety, high blood pressure, headaches, excessive sweating, and rapid heart rate.
Supplements that might help regulate norepinephrine levels include:
- Omega-3 fatty acids, which support overall brain health.
- Vitamin C and B vitamins, essential for adrenal gland function and neurotransmitter production.
- Herbal adaptogens like Rhodiola Rosea, which may help balance stress hormones.
Norepinephrine, when released in the body, can create a variety of feelings and physical reactions:
- Increased Alertness and Awareness: Norepinephrine sharpens focus and attention, making you feel more alert and aware of your surroundings.
- Heightened Energy and Arousal: It can give a sense of increased energy and readiness, often necessary for responding to stressful or demanding situations.
- Elevated Mood: In moderate amounts, norepinephrine can contribute to feelings of euphoria or a ‘natural high,’ often experienced during intense physical activity.
- Anxiety or Nervousness: High levels of norepinephrine, especially in non-threatening situations, can cause feelings of anxiety, nervousness, or restlessness.
- Rapid Heartbeat and Increased Blood Pressure: It causes the heart to beat faster and more forcefully, which can be felt as palpitations, and also constricts blood vessels, leading to increased blood pressure.
- Reduced Pain Perception: Like adrenaline, norepinephrine can temporarily reduce the sensation of pain, allowing for continued activity or focus in challenging situations.
- Fight-or-Flight Response: Norepinephrine is integral to the body’s fight-or-flight response, preparing you physically and mentally to either face a threat or flee from it.
