Dopamine is important for memory, learning, behavior, and movement coordination. Many people know dopamine as a pleasure or reward neurotransmitter.

The brain releases dopamine during pleasurable activities. Dopamine is also responsible for muscle movement. A healthful diet may help balance dopamine levels.

The body needs certain amino acids to produce dopamine, and amino acids are found in protein-rich foods. Meanwhile, eating high amounts of saturated fat can lead to lower dopamine activity, according to research from Also, certain studies suggest that a deficiency in vitamin D can lead to low dopamine activity.

While there are no dopamine supplements, exercise may help boost levels naturally. Endorphins inhibit pain signals and create an energized, euphoric feeling. One of the best-known ways to boost levels of feel-good endorphins is through aerobic exercise. Also, research indicates that laughter releases endorphins.

Endorphins may help fight pain. The National Headache Foundation say that low levels of endorphins may play a role in some headache disorders. A deficiency in endorphins may also play a role in fibromyalgia.

The Arthritis Foundation recommend exercise as a natural treatment for fibromyalgia, due to its ability to boost endorphins. It is both a hormone and a neurotransmitter. When a person is stressed or scared, their body may release epinephrine. Epinephrine increases heart rate and breathing and gives the muscles a jolt of energy.

It also helps the brain make quick decisions in the face of danger. While epinephrine is useful if a person is threatened, chronic stress can cause the body to release too much of this hormone. Over time, chronic stress can lead to health problems , such as decreased immunity, high blood pressure , diabetes , and heart disease. People who are dealing with ongoing high levels of stress may wish to try techniques such as meditation, deep breathing, and exercise. Anyone who thinks that their levels of stress could be dangerously high or that they may have anxiety or depression should speak with a healthcare provider.

Meanwhile, doctors can use epinephrine to treat many life threatening conditions, including:. In addition, epinephrine helps the heart contract again if it has stopped during cardiac arrest. Gamma-aminobutyric acid GABA is a mood regulator. It has an inhibitory action, which stops neurons from becoming overexcited. This is why low levels of GABA can cause anxiety, irritability, and restlessness.

They work by increasing the action of GABA. This has a calming effect that can treat anxiety attacks. These drugs are capable of changing the effects of neurotransmitters, which can alleviate the symptoms of some diseases. Drugs that can influence neurotransmission include medications used to treat illness including depression and anxiety, such as SSRIs, tricyclic antidepressants, and benzodiazepines.

Illicit drugs such as heroin, cocaine, and marijuana also have an effect on neurotransmission. Heroin acts as a direct-acting agonist, mimicking the brain's natural opioids enough to stimulate their associated receptors. Cocaine is an example of an indirect-acting drug that influences the transmission of dopamine.

Neurotransmitters play a critical role in neural communication, influencing everything from involuntary movements to learning to mood. This system is both complex and highly interconnected. Neurotransmitters act in specific ways, but they can also be affected by diseases, drugs, or even the actions of other chemical messengers. Learn the best ways to manage stress and negativity in your life.
